3. Plan work in accordance with Chemical Hygiene Plan Use equipment for designed purposeBe familiar with emergency equipment and procedures Know and use appropriate protective equipment Be alert to unsafe conditions and actions call attention to them correct them Personal responsibilities Work so that others (e.g., coworkers, the public) will not be harmed.

6. Lab is scheduled from 1:00 to 5:00 PM on assigned afternoons. Senior Lab Lab Schedule / Rules You are expected to manage your time and productivity to make the best use of your allotted time. Your employer will have the same expectation. Make-up time will usually not be granted. Students may not work in the lab unless an instructor, teaching assistant, or lab technician is present.

7. Senior Lab Clean up We start the semester with the lab clean and well organized. It is up to you to keep it that way. • Failure to clean-up everyday and at the end of your project will result in a reduction in your grade and the ire of Bob Cox. Clean-up is everyday at 4:30 PM, plan on this in your project schedule.

8. Safety equipment is available in each lab. There is no excuse for not using it. Senior Lab Safety - Your Responsibility You are responsible for the safety of your project, your team and your neighbors. A safety review will be part of your preliminary oral exam. Violations of safe practice will result in a reduction of your grade or suspension from the lab. As an engineer you are responsible for your own safety, the safety of your co-workers, and the safety of the public and the environment.

9. Safety glasses are required whenever you are handling chemicals or operating machinery. (PERIOD) Hard-hats are required when working on the grating area. Please do not drop tools on the students below! Use the fume hoods to reduce your chemical exposure. When handling strong corrosives such as full strength acids and bases, use a face shield, gloves, and splash apron. Senior Lab Safety - Protective Equipment

10. Gloves • Choose the type of Glove that will protect against the chemical you are handling • Glove Materials Permeation Test Data • Take glove off so that your skin does not make contact with contaminated area • See www.labsafety.com

11.  Glove Material  Applications  ~ Cost Butyl  A synthetic rubber material that offers the highest permeation resistance to gas and water vapors. Especially suited for use with esters and ketones. $12-20/pair Neoprene  A synthetic rubber material that provides excellent tensile strength and heat resistance. Neoprene is compatible with some acids and caustics. It has moderate abrasion resistance. $30-55/12pr Nitrile  A synthetic rubber material that offers chemical and abrasion resistance - a very good general duty glove. Nitrile also provides protection from oils, greases, petroleum products, and some acids and caustics. $11-12/100pr disposable (Chemistry) $16-60/12pr reusable PVC polyvinyl chloride  A synthetic thermoplastic polymer that provides excellent resistance to most acids, fats and petroleum hydrocarbons. Good abrasion resistance. $15/100 pr disposable $30-55/12 pr reusable PVA polyvinyl alcohol  A water-soluble synthetic material that is highly impermeable to gases. Excellent chemical resistance to aromatic and chlorinated solvents. This glove cannot be used in water or water-based solutions. $37/10pr Viton7  A fluoroelastomer material that provides exceptional chemical resistance to chlorinated and aromatic solvents. Viton7 is very flexible, but has minimal resistance to cuts and abrasions. $35-100/pair

12. Do not eat or drink in the lab. These are chemical handling areas. Do not pipette by mouth! Do not spill any chemicals. Spill containment and clean-up materials are located in lab 3520A. The removable gratings between floors must not be removed. Near fatal injuries have occurred in the past. Shorts and sandals are not appropriate attire in the laboratories. You can change before lab. Senior Lab Safety - Don'ts

13. Keep your work area clean and well organized, clean up any spills. ALL chemical containers must be labeled. After Consulting Guidelines for Drain Disposal of Chemicals, Contact your instructor or Bob Cox for disposal of chemicals and hazardous waste. Be aware of the danger of long hair, loose clothing and jewelry around rotating or moving equipment. Secure your long hair. Senior Lab Safety - Safe Practices

14. Exposure Limits OSHA Average over 40 hr work week Sickness Death Threshold Limit Value Threshold of smell Flamibility/Explosion Flamibility Limits Explosion Limits Safety Considerations

15. Hazardous Operations • Develop a plan of operation for hazardous experiments/equipment • Get plan approved • Document all operations to meet the guidelines of the plan

16. OTHER LABORATORY AREA HAZARDS • Compressed gas cylinders.A. Past accidents, projectile Hazard capable of penetrating concrete walls.B. Tanks must be securely belted or chained in place.C. Oxygen tanks must be segregated.D. Oxygen connections and lines must be oil free.E. Either a regulator or a safety cap must be in place at all times.F. The safety cap must be in place when moving the tank.

26. Each lab/work area must have appropriate spill containment and clean-up materials sufficient for the chemicals in use. Minor spills dealt with in the Lab. Two types of packs Acid Base Major spills require assistance, call University dispatch 5-2677 (5-COPS). Life threatening situations, ring fire alarm and evacuate. Senior Lab What to do for Chemical Spills

27. What to do in Power Outage • Close Fume Hoods • Secure Chemical Containers • Caps, Covers, etc. • Close cylinders at tank valve • Turn off non-essential equipment and large power draw equipment • Check all sensitive or reactive materials maintain cover gases or seals

28. Fire • Pull the nearest fire alarm and evacuate. • University policy is that students should not attempt to fight fires. • Any person having first hand knowledge of an alarm situation should report to the emergency response personnel in the parkinc7 lot at the northwest comer of MEB. • Close lab and hallway doors on your way out. • Never disregard a fire alarm. • Have an alternate escape route planned.

29. Earthquake. • Routinely close cabinet doors. • Hide under a heavy desk or door frame. • Evacuate cautiously, watch for falling glass.

30. Emergency Response

31. Many lab projects will generate hazardous waste streams. As part of your project planning, discuss the disposal issues with Instructor. Some hazardous wastes may be treated and neutralized. Guidelines for Drain Disposal of Chemicals Some hazardous wastes must be collected for disposal. All waste containers must be kept closed. Annual EPA inspections. Fines from past infractions.
