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 Toxic/Poison – A substance that can lead to death if inhaled, ingested, or absorbed by the skin. Corrosive – A substance that can destroy or burn living tissue and can eat away at other materials.

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.
