1. Laboratory Safety

2. You and your parents must agree to and sign the safety contract in order to participate in lab activities. Failure to comply with safety guidelines may result in your removal from the class and loss of credit for the work that is done in your absence.

3. Conduct in the Physics Lab 1. Food and drink are strictly prohibited in the laboratory. 2. When first entering the room, do not touch any chemicals or equipment until you are instructed to do so. 3. No unauthorized experiments are to be performed. If you are curious about trying a procedure not covered in the experimental procedure consult with your instructor.

4. Conduct in the Physics Lab 4. Coats, backpacks, etc., should not be left on the lab benches and stools. Be aware that lab chemicals can destroy personal possessions. 5. Always wash your hands before leaving lab.

5. 6. No matter how small the accident may seem, always notify the instructor immediately in case of an accident. This includes cuts, scrapes, burns, and any kind of broken glass. 7. Learn where the safety and first aid equipment is located and how to use them. Conduct in the Physics Lab

6. Safety Equipment Please note the location and proper use of the following lab safety equipment:  Eyewash Station: __________  Safety Shower: __________  Fire Safety Blanket:__________

7. Safety Equipment Please note the location and proper use of the following lab safety equipment:  Fire Extinguisher: __________  First Aid Kit: __________  Fume Hood: __________

8. How to use a Fire Extinguisher (PASS) PULL the pin: some extinguishers require releasing a lock latch, pressing a puncture lever, or taking another first step. AIM low: point the extinguisher nozzle (or its hose) at the base of the fire. SQUEEZE the handle: This releases the extinguishing agent. SWEEP from side to side: Keep the extinguisher aimed at the base of the fire and sweep back and forth until it appears to be out..

9. How to Dress for Lab 1. You must wear the safety goggles provided by the chemistry department. at all times while in the lab. This rule must be followed whether you are working on an experiment or simply writing in your lab notebook. 2. Contact lenses are not recommended. Chemicals can accumulate under the lenses and cause serious injuries or blindness. Please note that if the eye wash is used and you are wearing contact lenses, you will lose your contacts. good bad

10. How to Dress for Lab 3. Closed toed shoes and long pants are suggested. Sandals and shorts are discouraged. 4. Long hair must be tied back when using Bunsen burners.

11. Proper Handling of Chemicals and Equipment 1. Consider all chemicals to be hazardous unless you are instructed otherwise. Material Safety Data Sheets (MSDS) are available in lab for all chemicals which are in use. These will inform you of any hazards and precautions of which you should be aware. 2. Know the chemicals you are using. Carefully read the label twice before taking anything from the bottle. Chemicals in the lab are marked with a National Fire Protection Agency (NFPA) hazardous materials diamond labels. Learn how to interpret these labels.

12. Proper Handling of Chemicals and Equipment  Dispose of chemicals properly. Waste containers will be provided and their use will be explained. Unless you are told explicitly told otherwise, assume that only water may be put in the lab sinks.  Clean up all broken glassware immediately and dispose of the broken glass properly.  Never leave burners unattended. Turn them off whenever you leave your workstation. Be sure that the gas is shut off at the bench rack when you leave the lab.  Beware of hot glass- it looks exactly like cold glass.

13. Safety Symbols to Know  Flammable – Any substance that will burn if exposed to an open flame.  Explosive – A substance that may explode if exposed to heat or flame.  Toxic/Poison – A substance that can lead to death if inhaled, ingested, or absorbed by the skin.

14. Safety Symbols to Know  Corrosive – A substance that can destroy or burn living tissue and can eat away at other materials.  Radioactive – A substance that emits radioactive particles.  Irritants –Substances that are noxious or irritating.

15. Hazard Diagram  NFPA Diamond: This is the labeling system used by the National Fire Protection Association (NFPA). This label utilizes a diamond divided into four smaller diamonds, which represent specific hazards.

16. Material Safety Data Sheet (MSDS)  A MSDS is a document prepared by a chemical manufacturer describing the potential hazards, physical properties, and the procedures for safe use of a chemical substance. It is intended to tell what the hazards of the substance are, how to use the substance safely, what to expect if the recommendations are not followed, what to do if accidents occur, how to recognize symptoms of overexposure, and what to do if such incidents occur.
