A Material Safety Data Sheet (MSDS) is designed to provide both workers and emergency personnel with the proper procedures for handling or working with a particular substance. MSDS's include information such as physical data (melting point, boiling point, flash point etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill/leak procedures. These are of particular use if a spill or other accident occurs.

Laboratory Safety Rules Hypothesize: what do you believe to be the 5 greatest dangers in a science lab – list them in ascending order

Why is Lab Safety important? Lab safety is a major aspect of every lab based science class. Lab safety rules and symbols are needed so that students do not injure themselves or their classmates.

Hands-on experiences are essential to learning in science class, but safety must be the first concern! The following rules exist for your safety. These rules help to prevent accidents in the lab and allow for more efficient work to occur.

Lab Safety Rules 1. Always follow the teacher’s directions and only do lab work when a teacher is present. 2. Conduct yourself in a responsible manner at all times. No Horseplay! 3. Do not touch any equipment, chemicals, or other materials until told to do so. 4. Do not eat food, drink beverages, or chew gum in the lab. Do not use lab glassware as food or beverage containers 5. Report ALL accidents to your teacher immediately, even if you think it is minor.

When first entering the science room, do not touch any equipment, chemicals or other materials until you are instructed to do so. NEVER enter the room if unsupervised.

Stay focused & pay attention to all written and verbal instructions. Ask questions before proceeding if you are unsure. Know what you are to do before you do it.

Misbehavior CANNOT and WILL NOT be tolerated! Don’t be a statistic! Immediately notify your teacher of any unsafe conditions you observe. Work with your group at your station only. Meaning no wandering or visiting other lab groups! Be ON TASK at all times You Are NOT This Age !

Report all accidents immediately, no matter how small. This includes broken glass, cuts and scrapes, chemical spills and fire. Learn the proper techniques for handling these accidents. Remain calm!

CLOTHING… Do NOT Wear: Wear: Sandals Jewelry Loose or Baggy clothing Goggles/safety glasses Closed-toed shoes Gloves as needed Clothing made of natural based fiber such as cotton Tie back long hair

Please note the location and proper use of the following lab safety equipment found in your school: Eyewash Station Safety Shower Fire Safety Blanket Fire Extinguisher First Aid Kit How to call the Office Safety Goggles

NEVER eat or drink in the lab. Anti-Eating Mouth Cage US Patent Issued In 1982 http://www.totallyabsurd.com

Keep hands away from eyes, mouth and body while using chemicals. Wash your hands with soap and water after performing lab activities. NEVER touch, taste or smell any chemicals unless specified to do so.

Never rinse anything down the sink without the permission of your teacher. Note the “SAFETY TIPS” on your lab before conducting lab activities.

Use the posted procedure and evacuation route for exiting the classroom and building if necessary. Return all equipment and supplies to the proper storage area.

Other Chemical Hazards and Symbols Flammable Explosive Toxic/Poison Irritant Corrosive Environmental

Chemical Hazard Symbols and Definitions Flammable – Any substance that will burn if exposed to an open flame. Explosive – A substance that may explode if exposed to heat or flame.

Chemical Hazard Symbols and Definitions Irritant - A substance that causes inflammation upon contact with skin or mucous membranes. Environmental - Substances that are harmful to the environment. They must be disposed of properly, not washed down the drain.

Waste Disposal First ask your teacher where/how to dispose of waste. Never pour anything down the drain unless you are told to do so. A waste bottle will be supplied for substance that cannot go down the drain

Reasons for proper waste disposal Hazardous chemicals down the drain can lead to pollution of ground water, lakes, rivers, etc. Plants and animals will die if they are exposed to hazardous chemical waste. Serious health problems will become present in people if hazardous waste finds its way into drinking water.

You and your Parents must agree to and sign the safety contract in order to participate in lab activities. You man not engage in any further labs requiring equipment until the Safety Contract is signed!
