General Lab Rules

INTRODUCTION

These facilities were created to serve the following functions:

  1. To support education, manufacturing, design, and project coursework for all CEAT Departments.
  2. To provide general shop facilities including, but not restricted to, machining, welding, woodworking, and general fabrication for all CEAT educational operations, for undergraduate students, as well as graduate students.

The Design and Manufacturing Lab (DML) is located at 1724 West Tyler, the Manufacturing Development Lab (MDL) is located at 1702 West Eskridge Ave. and the Manufacturing Fabrication Lab (MFL) is 1701 West Eskridge Ave.  Permits are required to park in the lots from 5:00 am to 5:00 pm Monday-Friday.  The day-to-day operation of the facility is under the direction of the College of Engineering, Architecture, & Technology.  This direction is facilitated through a DML Manager (office in DML 123J) and MDL Manager (MDL 102) who reports to a CEAT faculty member designated as the Lab Director.  The Lab Director reports to the CEAT Assistant Dean of Academic Affairs. The names and contact information for these individuals will be posted near the entrance to the building.  

GENERAL POLICY FOR LAB USAGE

Since these facilities are for the support of instructional activities, the machines and tools are not to be used for personal projects or organizations outside of CEAT.  This rule holds for students, student technicians, staff members, and faculty members.  Similarly, no tools, machines, or supplies are to be borrowed or removed from the building unless approved by a Lab Manager.  This policy prohibits, for instance, the repairing of personal autos or bicycles, the construction of parade floats or house decorations, or the construction of hobby-type items.

Since safety is the primary concern, no admittance to the machine shops, welding shops, sheet metal shop, or wood shops will be made unless an appropriately trained CEAT employee is on duty.  Every attempt will be made to offer those students working on independent projects enough operating hours to cover their needs.  No keys to the above-mentioned shop areas will be checked out to individual students, clubs, or groups.

The labs are divided into closed shop and open shop areas.  The closed shop is not intended to be used by the general student population.  If students want to use machines in a closed shop area for project work, they must first make arrangements with a Lab Manager. 

We encourage the development of a Safety culture in and around the labs, as such safety rules will be enforced by employees (staff, faculty, and student technicians) and by students.  Any student observing other students operating tools in a dangerous manner is bound by engineering ethics to mention this to those involved and/or the supervising employee.  Staff and faculty members are obligated to police the various shops for safety violations and are called upon to administer penalties or warnings.  

NAME BADGE & SHOP CERTIFICATION SYSTEM

All students are required to wear name badges in all work areas within the CEAT North Campus Manufacturing Labs.  These areas are shown graphically in Figure 1, Figure 2, and Figure 3.  The name badge requirement goes into effect during the 3rd week of the semester.  After that time, any student without a name badge will not be allowed to work in the shop areas until one is obtained, unless working on training part. 

Level 1 (White Badge):   To get a name badge, students must first complete the Hazard Communication and the General Safety trainings.  After the quizzes are successfully completed, a name badge will be issued.  Both quizzes are now available on BrightSpace as a self-registration course called (CEAT North Campus Labs –STW_CEAT North Campus Labs).  You are requested to wait at least 48 hrs after receiving a 100% on the quizzes before you request a badge.

NOTE:   Students who lose their name badge will be charged $5.00 for a replacement. 

Students at Level 1 must be trained on the operation of mills and lathes before they can use these machines. Training can be provided by course instructors, student organization advisors, the lab manager, or his designee.  Students at Level 1 will only be allowed to use the machine shops when participating in a supervised training session/class or when one-on-one supervision is provided.  Some periods of time will be designated as training sessions in the open machine shop.  This will allow students to practice using the machines in a supervised environment, enhance their skills, and achieve the next level of certification if desired. 

Machine Shop Access (Green Badge):  The lab manager will certify when students have progressed to this level.  They may require the student to successfully complete a demonstration before granting the certification.  A green badge does not mean that a student is an expert machinist; it means that he/she is capable of running machines with less supervision.  These students will be given general shop access during regular open machine shop hours.  Students should always be prepared to ask for help from instructors or lab employees as needed. 

Aero Access (Blue Badge):  Access to the Aero Composites Lab (DML 128) and Aero Assembly Lab (DML 130) is determined by the DML Aero Committee. This access is only valid for the time period granted. This area is not a part of the general CEAT North Campus Labs.

PROCEDURES FOR PERSONAL INJURY

All injuries, regardless of severity, must be reported to the Lab Manager, or in his absence, to the CEAT employee who is on duty.  If the injury to the student or staff member is relatively minor, he/she can be treated with the contents of the first-aid kits available in all machine areas.  These kits contain materials for bandaging small cuts or dressing small burned areas.  Minor cuts, fractures, burns, and abrasions can be treated at University Health Services (1202 W. Farm Road) during their normal business hours, which are 8:00 a.m. until 6:00 p.m.  These services are available to students and to employees and the charges incurred are to be paid for by the injured party, although UHS will file insurance claims. 

If the injured person is incoherent, comatose, or otherwise in trauma, he/she should be transported by ambulance directly to the Emergency Room at Stillwater Medical Center.  The ambulance is called by dialing 911. 

Any OSU employee, who is injured while on duty at the DML, above the need for a standard first aid kit, must file a Workman's Comp. form with the Staff Assistant in the MAE main office, EN 218D.  All injuries must be reported, as soon as possible, to the Lab Manager.

BLOOD-BORNE PATHOGENS

Any body fluids deposited on the floor, on machines, or on furniture must be dealt with as being a pathogenic material.  A kit is available for this type of cleanup, which includes absorbent powder, storage bags, plastic gloves, and disinfectants.  Only trained/designated personnel should clean up blood or other bodily fluids.  If there is any doubt about the severity of the situation, OSU Environmental Health Services should be called immediately at extension x4‑7241.  Our first concern is for the safety and wellbeing of the injured party.  However, any person who is bleeding, even for minor cuts and abrasions, should control the bleeding as soon as possible to prevent contamination of lab machinery, tools, furniture, etc.

FOOD, DRINK, TOBACCO

Use of Tobacco

Tobacco and smoking preparation use are prohibited in buildings, vehicles and grounds owned, leased or under the control of OSU, with the exception of a limited number of residential facilities. Tobacco use includes, but is not limited to, the carrying by a person of a cigar, cigarette, pipe, or other lighted smoking device or the use of smokeless tobacco including snuff, chewing tobacco (including chewing on an unlit cigar or other tobacco product), smokeless pouches, or any other form of loose-leaf, smokeless tobacco. Smoking preparations include but are not limited to hookahs, electronic cigarettes, vapor devices, and clove cigarettes.

Use of alcohol

Oklahoma State University alcohol policy. It is forbidden to consume, possess, or serve beer and alcoholic beverages on the campus. Do not operate power tools when you are ill, taking strong medications,

fatigued or recently consumed alcoholic drinks.

Use of Food

No drinks, candy, or food are to be consumed in the machine shops, the wood shop, or the welding shop.   Food or drink containers may be contaminated with small metal particles or cutting oil, and it is unsafe to operate a machine tool while eating and drinking. Food and Drink are only permitted in designated areas and you should clean up the area when you are finished eating, by wiping down the area and placing left-overs and containers in trash.  

CELL PHONES

Students must silence cell phones when working around machinery in any of the shops.  Also, students must leave the shop area to text or talk on the phone. Use of these devices can be distracting to you and others who may be operating dangerous machines. 

PETS

No pets of any kind should be brought to the DML.  Assistance animals that are approved by Student Disability Services are acceptable.

SHOP DRESS CODE

All persons, whether students, employees, or visitors in the lab, must abide by a few simple regulations pertaining to shoes and clothing, when working, or even just "watching" in any of the work areas (designated in Figure 1, Figure 2, and Figure 3).  These regulations are driven by safety considerations and are similar to what one would find in any factory or commercial lab. The lab manager or lab director, do reserve the right to allow modifications to the dress code depending on the status of the lab, for visitors and group tours. 

When in a work area-

CLOTHING and SHOES:  Anyone in a work area (Weld areas, woodshops, machine shops, etc) are required to wear long pants and shoes that cover the entire foot.  Do not wear short pants or skirts.  Flip flops, sandals, house shoes, slippers, clogs, or any other kind of open-toed shoe is not permitted in any of the work areas.

When working with machinery-

HAIR:  No long hair, including ponytails or pigtails, is permitted around any of the machinery or power tools.  If the student/staff member has long hair, it must be secured in some fashion, such as tucking it under a cap, putting it inside a shirt, or clipping it securely to the top of your head.  Long hair can become tangled in rotating machinery and can result in severe injury and in some cases death.

CLOTHING:  No loose, floppy clothing is permitted on persons actually working on any of the machines.  Long shirt sleeves must be rolled up.  Old but serviceable clothing is recommended since water-soluble cutting oil droplets are often ejected in the machine areas.  When welding, brazing, torch cutting, or plasma cutting, old clothing should be worn, covering all skin below the welding mask.  Protective welding gloves are available.  Arc welding and plasma cutting produce intense ultraviolet radiation, which can burn skin, but which may not show up until several hours later.

JEWELRY:  No necklaces, chains, pendants, bracelets, etc. are to be worn for the reason that they can become entangled in rotating machinery.  Rings and watches must be removed or completely covered with tape.

EYE/FACE PROTECTION

  1. Safety glasses meeting ANSI Z87.1, 1989, standards, with side shields, must be worn by all personnel (students, faculty, employees, and visitors) at all times when working or walking through the “open” machine shop, the closed machine shop, the wood shop, the welding shop, and the Baja and Formula team assembly areas, and when posted in the "Low Bay" area and the "High Bay" area. Safety glasses must also be worn in any areas when there is a danger of flying debris due to hammering, drilling, tapping, grinding, sanding, etc.  Figure 1, Figure 2, andFigure 3for schematics of the buildings that show areas where safety glasses are required.  For persons requiring regular eyeglasses, safety glasses or goggles must be worn over the eyeglasses.  In the case of a non-active lab, the lab managers reserve the right to wave this restriction.

Each student is required to purchase his/her own safety glasses.  These should not be loaned to other persons because of hygienic concerns.  Safety glasses are available at most hardware stores, such as Atwood’s, Fastenal, Lowe's, or Wal-Mart, and at the Fastenal vending machines.


 

Figure 1.  DML Schematic for Work Areas

2. Full face shields must be worn by any person operating any grinder. The face shield is worn along with regular safety glasses.  The face shield should be worn, in general, when there exists any possibility of splinters, chips, or scraps being thrown toward the operator.  Ordinary safety goggles protect the eyes but not the remainder of the face. 

3. Welding masks must be worn by persons doing any form of arc welding or plasma cutting, along with safety glasses.  When doing acetylene cutting or acetylene welding, tinted goggles or face shield must be worn in addition to safety glasses.

4. Welding screens must be used to protect passers-by.  The Lab Manager should be consulted if there is any question about the proper protection required.  These regulations cover not only those doing the actual welding but also those persons who might be helping.

5. Persons walking past an area in which welding or plasma cutting is taking place shall avert or cover their eyes in the event the radiation shield is not in the proper place. 

HEARING PROTECTION

Hearing protection shall be worn in areas of high noise and/or where indicated by signs.  The sound pressure level at which hearing protection is required is 90 dBa.  A few machines, such as pneumatic grinders and some woodworking tools may produce sounds of this level or higher.  If the sound level of the machine is high enough that it is difficult to talk to a person standing two feet away, without shouting, then ear protection is required. Another indication of high noise levels is the presence of "ringing" in the ears after the machine is turned off.  Inexpensive disposable ear plugs can be purchased at drug stores, hardware stores, and building supply stores.  Earmuff-type hearing protectors are the most effective but should only be used by one person due to the possibility of passing on infections.  If the student regularly works in a high noise area, he/she shall get earplugs from the Fastenal vending machines or purchase earmuffs.   

PROTECTION FROM DUST AND PAINT EXPOSURE

All persons engaged in sanding materials that generate dust (e.g., wood, composite material, metals, plastics, etc.) should wear comfort masks.  Disposable comfort masks are available from staff or the Fastenal Vending Machines only after completing the N95 Filtering Facepiece Training and Quiz.

If a respirator is required, the student must contact OSU Environmental Health and Safety to start the process.

If sanding is to be done to remove paint from a machine or structure, the surface shall be tested for lead content.  An inexpensive test kit for lead paint is available at all paint stores and at most builders' supply stores.  If lead paint is detected, no sanding is to be done.

Spray painting shall be done outdoors and never in such a way that fumes can drift back into the building or be pulled into the air conditioning system, contaminating the entire building.  For small painting jobs, a table is available that can be rolled outside the building.  The part to be painted can be placed on the open mesh or suspended from the built-in rack.  Painting is never to be done on the grass or on a concrete surface.  Painting must never be done when there is a risk of the wind-borne particles drifting toward other persons or on to parked vehicles.

The store from which the paint was purchased will supply SDS information and can also supply information about any required respirator cartridge.  Some automotive paints are extremely toxic and must not be used in the buildings or anywhere on the grounds.  The propellant used in some paint spray cans may be flammable, and as a safety precaution, these spray cans should never be used around flames.

Work areas must be cleaned by the persons doing the painting or sanding.  Sanding dust must be collected, and any remaining paint thinners, paint remnants, etc., must be placed in specified containers.  CEAT North Campus Lab employees must be consulted about proper disposal of these items.

ACQUISITION AND STORAGE OF CHEMICALS

Storage and handling of chemicals is covered in a "Hazard Communications" training session and documents.  Only the main topics are briefly covered here.  OSU EHS requires all employees of the University to have training in Hazard Communications one time per year. This is also required of students using the North Campus labs.

Any chemical (including oils, fuels, glues, paints, thinners, fluxes, solvents, acids, etc.) must have an SDS, or Safety Data Sheet.  The sheets must be kept in a file in the room in which the material is being used, and the file must be labeled.  Each material has ratings that apply to flammability, toxicity, etc.  Some materials will have to be stored in one of the flammable liquids storage cabinets provided in the DML, Development Lab, and Fabrication Lab. 

Chemicals with an NFPA rating of 3 or 4 must be approved for use in the North Campus Labs.

The Lab Manager must be informed as to what chemicals are brought into the lab, and he must be supplied with the SDS sheet.  It is the duty of the student to acquire the SDS sheets from the vendor who sold the material or from a database.  No chemical is to be brought into the lab without the proper SDS sheet.

Do Not Pour chemicals (paints, solvents, etc.) down the drain.

Discarded materials such as paint thinner and/or solvents must be turned in to a lab employee or the Lab Manager, who will store these materials in safe, labeled containers until they can be picked up by OSU personnel who handle hazardous wastes.  If unknown chemicals are mixed in a container, the contents will have to be analyzed, which is a very costly process.  Violators who mix chemicals without complete labeling will have the analysis and disposal costs charged to their bursar accounts.

Use of Products containing Polyester Resins PROHIBITED without prior approval

If approved, all PPE per the SDS will be used. 

BOTTLED GASES

Bottled gases, such as acetylene, oxygen, argon, and carbon dioxide, must be kept secured.  This means the bottles must be chained to the wall or must be clamped into a dolly designed for this purpose.  The reason for this is that if a bottle falls over, the valve at the top can be broken off.  When this happens, the bottle becomes a rocket and can cause serious injury.  Be sure to close the hand valve at the top of the bottle after each use.  If the valve is left open, the pressure regulator might allow the gas to continue seeping out.

Anyone handling these bottles must complete the Compressed Gas Cylinder Safety quiz now available at the CEAT North Campus Labs –STW_CEAT North Campus Labs BrightSpace site.  

ELECTRICAL SAFETY

Very little current is required to cause electrocution!

Students are not permitted to perform any electrical modifications or repairs in circuits with voltages above 50 Volts, or currents greater than 15 amps. Students may work with DC and AC control circuits and data acquisition circuits and wiring that do not exceed the limits above. No electrical work should be performed on any live (e.g. switched on) circuit. Circuits built with electrical storage (e.g. capacitors) should not to be worked on prior to the manufacturer published (or calculated) wait time post disconnect of power.

All electrical equipment and circuits regardless of voltage level, should have a suitable means for identifying wiring. Detailed schematic drawings, circuit diagrams, and color coding, shall be submitted as part of the project SOP. All electrical wiring will conform to NEC/ OSHA regulations.

Before students operate any high voltage equipment, voltages 120 Volts AC or greater, there must have an active SOP in place and have obtained permission from designate personal.

Students must not attempt high voltage electrical repairs. If equipment has a frayed cord, damaged insulation or plug, or causes even a minor shock, it must be removed from service and reported to NCL staff so corrective action can be taken.

EXTENSION CORDS

Avoid using extension cords whenever possible. Extension cords should not go under doors, across aisles, be strung across the ceiling, or plugged into other extension cords. If an extension cord is used, students should confirm with NCL staff that the cord is correctly rated for the load being applied. Don't assume that a cord is heavy-duty simply because it's bright orange and thick. If the insulation on the extension cord has become damaged, don't try to repair the cord. You should bring the damaged cord to the attention of a NCL staff member, more than likely it will be replaced. This could prevent electrical fire, or electrocution.

Before using an extension cord one should; Check cords for damage, ensure cord is rated for the load, make sure the cord is completely plugged into the outlet and has some strain relief, minimize trip hazards when routing the cord, and when you finish unplug extension cord, roll it up, and return to storage.

GROUNDING

All 120-volt circuits in the lab have a "hot" wire, a neutral wire and a ground wire.  The plugs for most power tools have three prongs on the end for these three wires. The longest prong is the ground.  Only extension cords having the three-prong plugs should be used, and keep cord away from water. Ground fault circuit interrupter protection must be used when extension cords are in wet or damp environments.

Some of the plastic or hard rubber power tools have only two blades on the plug, with one blade being wider than the other.  This is a polarized plug and will normally fit into a wall outlet only one way.  These tools are referred to as being "double insulated" and are not connected to ground.  You will also see this type of plug on consumer products such as drill motors, saws, hair dryers, etc.  Bear in mind that these tools are safe from shock hazard only because the plastic parts do not conduct electricity.  The blades of these plugs should never be altered or forced into a socket.

USE OF ELECTRICAL TOOLS IN WET AREAS

The rule for this is: DON'T!!

Most electrical codes now require the use of ground fault circuit interrupters (GFCI) on circuits having outlets close to sinks or on circuits used outdoors.  The GFCI has internal circuit breakers that compare current in the "hot" wire with that in the neutral wire.  If there is a difference, a small relay will trip, indicating that some of the current is leaking away, through a short, or frayed wire, or through someone's body.  GFCI plugs are available on extension cords for outdoors use.  

BREAKERS, SWITCHES, PANELS

Students must never touch or reset any of the breakers in any of the panels mounted anywhere in the buildings.  If a machine or computer quits running, please notify an employee.  If you flip breakers at random, you may shut down someone's computer, damage a machine, or cause an accident.

Do not open the disconnect box or the starter box of any machine tool.  Fuses in disconnect boxes are to be changed only by employees.  Nothing should be stored in such a way as to limit accessibility to electrical panels, disconnect boxes, or motor starters. 

BAND SAW OPERATION

Band saws can be used to cut various types of metal, plastics, and wood.  However, the proper blade and blade speed must be used for each material.  For instance, it is dangerous to use a “wood" blade to cut metal.

The work being cut is hand-held so it is important to keep your fingers clear. 

Some safety rules for band saws:

  1. Adjust the upper guide to about 1/8" above the material being cut.
  2. If you are uncertain about the type of blade, blade tension, or speed, ask one of the employees to check it for you.
  3. Do not attempt to saw anything that does not have a flat surface to press against the table.  For example, if you attempt to cut something that can “rock,” the blade may cause the part to spin, and the blade could jam.
  4. Stop the machine to remove scrap.
  5. Stop the machine to back the blade out of an uncompleted cut.
  6. Never leave the machine running while unattended.
  7. Keep fingers clear of the blade area.  Hold material firmly and feed at a moderate rate.  If the saw sounds as if it is slowing down, you are feeding too fast.
  8. A blade that has several teeth knocked off will cause the work to jerk and will make a pulsing sound.  The machine must be shut down immediately.

DRILL PRESS OPERATION

We have both light duty drill presses with "Jacobs" type keyed chucks as well as heavy duty presses that use Morse taper collets.  Only those people with acceptable shop experience may use the heavy-duty presses.  The smaller presses can be used for drilling wood and light metal.

  1. After using the key to tighten the chuck, be sure to remove the key. (Some keys have spring-loaded nibs that will push the key out anyway.)
  2. The material you are drilling must be clamped down to the table or held securely in a drill-press vise, which is bolted or clamped to the table.  If a drill bit "grabs" a piece of metal or a board, the work material becomes a rotating weapon, which can chop off fingers or worse.
  3. When using any sort of drill bit or hole saw, the bit must be matched to the material being drilled.  The correct speed must also be selected.  If smoke arises from the part while drilling, you should stop immediately.  Your bit, or holesaw, or whatever, is probably dull.  Never "hang" with your weight on the elevating handle.  If it requires this much force, it means that the bit or saw is dull or is improper for the material being drilled.

SHEET METAL FOOT SHEAR OPERATION

Sheet aluminum and mild steel can be cut by a foot-operated shear.  The allowable gage (thickness) and width are specified by a small sign affixed to the frame of the machine, and these ratings must never be exceeded.  The operator should place only one foot on the treadle, leaving the other foot free for balance.  If the metal does not shear when you are putting your full weight on the treadle, this means that the thickness or width is too great, and you should consult with an employee about an alternate method of cutting the material.

UNDER NO CIRCUMSTANCE SHOULD TWO PEOPLE STAND OR JUMP ON THE TREADLE.  THE CONNECTING LINKAGES CAN BE BROKEN AND THE OPERATORS INJURED.

HYDRAULIC SHEAR OPERATION

A hydraulic shear is available in the wood shop area.  This machine can shear mild steel and aluminum up to 10 gage at a width of 52 inches.  Students are not to operate this shear but can ask shop personnel to make any cuts they may require.  Student shop technicians must be trained in the use of this machine by the Lab Manager.

STRIKING TOOLS (HAMMERS, ETC.)

There are several types of hammers, each having a definite purpose.  Eye protection must be worn when using any type of hammer.

The claw hammer is to be used only for driving nails.  It must never be used with punches, cold chisels, drifts, or other hardened steel tools.  The claw hammer usually has a hardened face, which can chip if used to strike something hard.  Even when driving ordinary nails, chips of the nail head or hammer can fly off, causing injury.  If a nail is struck a "glancing" blow, the nail can fly out in any direction.

When using cold chisels, punches, or drifts, a ball-peen hammer or machinist's hammer must be used.

MILL & LATHE OPERATION

There are several different types of metal lathes and mills throughout the North Campus Manufacturing Labs.  After completing your Safety and Hazmat training, you must be trained by a NCML employee before operating any of them. 

You must sign up for one of the training sessions that are posted. You can contact a Lab Manager to obtain training time and place if none are posted. Sign up takes place on SignUpGenius.

After completing this training you will receive a Green badge allowing mill and lather operation. 

BENCH, PEDESTAL, AND HAND-HELD GRINDER OPERATION

Note:  The main types of grinders you might use are the bench and pedestal grinders.  They are the same except that the pedestal grinder is mounted on a heavy stand whereas the bench grinder is designed to sit on the workbench.  These grinders usually have two wheels, each with its own guard and tool rest.  These grinders are to be used dry, with no cutting fluid.  Hand-held grinders can be used for dressing welds or smoothing the edges of cut plate steel, or tubing.

  1. Grinding wheels are by nature very brittle and can shatter.  Therefore, the operator must wear a full-face shield and safety glasses.
  2. The operator must allow the wheel to come up to full speed before beginning grinding.  Similarly, grinding operations must be finished before turning the motor off.  The wheel will require a long time to coast down.  Do not try to slow the wheels by dragging any material against the wheel while it is coasting.
  3. The guard must be in place and the work rest must be adjusted properly. If you have questions, ask one of the shop employees.
  4. Grinding must be done only on the face of the wheels--never on the sides.  Applying force to the side of the wheel can cause it to explode.  You must never apply enough force to the wheel that you cause the motor to slow down.  The exception to this is that a hand-held grinder is designed to use the side of the wheel, and not the edge.
  5. Grinding wheels are rated by an abrasive grade number.  For example, a "30 grit" is very coarse whereas a "500 grit" is very fine.  You must not change the wheels yourself.  Ask a shop employee.  If a wheel is not installed at the correct torque with the correct flanges, it could explode.  Grinding wheels must be used below the maximum rated speed.
  6. Every wheel grinder in the North Campus labs shops is set up for grinding only ferrous material.  DO NOT grind aluminum, copper, soft brass, etc. because these materials will cause the wheels to "load."  Two bad things can then happen:  1) The metal embedded in the wheel will cause the temperature to rise very rapidly, and the wheel can explode in the operator's face!  2) The wheel is rendered useless until it is refaced by one of the employees.  If you have any doubt about your material, just remember that ferrous materials are generally magnetic.  And, if you see a shiny residue on the grinding wheel, you must shut it down immediately.  This residue is a soft metal, filling the pores of the grinding stone.  Note:  Nonferrous metals, some plastics, etc., can be ground, but only with the proper equipment, the correct wheels, and the required coolant.  

WOOD SHOP RESTRICTIONS

Students will be allowed to use only the scroll saws panel saw, drill press, belt sander, and the vertical band saw in the wood shop, with permission.  Students will not be allowed to use the thickness planer, joiner, or table saw.  If there is a need to have wood pieces cut by any of these machines, the Lab Manager must be consulted for assistance.  

COMPUTER LAB (DML 125)

DML Room 125 has been set up as a CAD/CAM computer lab that is open to all of CEAT.  The lab will be open and available for students to use 24 hours per day, EXCEPT when a class is scheduled in the room.  A room schedule will be posted by the door to show when scheduled classes meet.  Room 125 should not be used for any purposes other than computing.  It is NOT a workshop, and no tools are to be used in this space. A smaller computer lab is also located in the MDL and will be loaded with the typical CEAT software image. Systems will require students to log in with their OKey credentials. Students are not allowed to unplug computers or cables. If there is an issue with a system, please let one of the lab managers know.

APPROPRIATE WORK AREAS

Students performing manual production or assembly activities should only do so in designated bench work areas.  Improper areas for this type of work include DML125 (the computer lab), any office, and the restrooms.  Figure 4and Figure 5shows a schematic of the building and identifies the areas where this type of work can be done.

POLICY FOR PROJECT OPERATION

  1. Testing at the CEAT NCML, MD-80, and UAFS.

For any project potentially requiring any testing at the North Campus Manufacturing labs, MD80, or airfield, a Standard Operating Procedure (SOP) will be turned in to the Lab Manager, in electronic form, for approval by the DML Safety committee. This SOP form is located at ncl.okstate.edu. This SOP will list responsible faculty, team members, project description, expected hazards, operating procedures with hazard mitigation, first aid procedures, etc. The committee will determine acceptability of the SOP within 48 hours.  A North Labs manager must approve test locations and times. The PI, the responsible faculty, or a North Labs Safety committee member must be in attendance for the initial testing and for subsequent testing, if deemed necessary.

  1. Fuels for Internal Combustion Engines

No gasoline, propane, etc. shall be stored inside any buildings. The Lab Manager shall designate a storage area for the fuels used in the various racing programs or other projects. SDS must be on file for all fuels used.

  1. Operation of Internal Combustion Engines

No Internal Combustion Engines shall be operated inside buildings without adequate venting, with the exception of the forklifts.  Engine tests shall be run outdoors, in such a location that fumes are not allowed to enter the building. All Engines will be secured during operation. Procedures and designated testing area(s) will be documented in the project SOP.

  1. Operation of Rotating Devices (Propellers, Shafts, etc)

The testing is to take place behind a protective screen.  The device must be safely secured to avoid movement.  Anyone in the vicinity should be behind the screen and wearing eye protection.

No rotating devices will be operated except with proper procedures and guarding in place to prevent contact with rotating shafts or propellers. Procedures and designated testing area(s) will be documented in the project SOP.

  1. There will be NO Untethered flights on OSU Campus

All planes, helicopters, etc. shall be tethered to the ground to prevent operation outside of a designated area. Designated operation areas shall be marked clearly to prevent any person from entering the operation area. Operation area and tethering is subject to approval by the Safety committee and shall be contained in the project SOP.

  1. Test Areas

Designated test areas will be clearly marked. Only designated project team members will be allowed in the test area and only according to the Standard Operating Procedure (SOP). Test areas will be determined by the Lab Manager.

POLICY ON FORKLIFTS AND TRUCKS

The DML has one forklift truck, three pickup trucks, and three trailers.  The Manufacturing Fabrication Lab has one forklift. All of these are controlled by the Lab Managers.  

  1. Use of forklifts

Only employees who have had the university training and certification may use the forklifts and only with the permission of the Lab Manager.  The training is available through the Safety Department, a division of Environmental Health Services.

  1. Use of pickup trucks

These vehicles are to be driven only by approved MAE employees, or other CEAT employees as approved, and only with permission of the DML Lab Manager. "Employees" include faculty, full and part-time staff, teaching assistants, and research assistants. Any person driving one of these vehicles must have a valid U.S. driver's license and must have his/her own liability insurance.  Drivers will be asked to enter trip data in a log for out-of-town trips.  Pickups and trailers, owned by MAE or any OSU entity, are never to be used for personal business.  This is an OSU policy. This means that the trucks are to be driven only to the declared destination and not used for shopping, etc.   Use of these vehicles should be requested well in advance, since they are heavily used.

  1. Use of utility trailer

The same restrictions apply as for the pickup trucks.

  1. Use of covered trailer

This trailer was donated to MAE for transporting SAE Formula cars, BAJA cars, and Aircraft Design Capstone Airplanes.  Use of the trailer must be scheduled through the DML Lab Manager.  It is advisable for the student groups mentioned above to schedule all trips as soon as the dates are known.
