DO

• Seek information and advice from your local municipality regarding litter control, waste disposal and environmental standards.
• Minimize potential for environmental damage (e.g., do not pour chemicals down the drain, on the ground, into storm sewers; recycle or compost trash as much as possible; etc.).
• Follow approved procedures from local municipality and environmental agencies for the disposal of unwanted or waste chemical products.
• Minimize waste by composting vegetation waste.
• If trash is being burnt, ensure that someone watches the fire until it is completely extinguished.
• Have water available (pails and/or hoses) to control/extinguish fire.
• Recycle paper, glass, metal and plastic products whenever possible.
• See the OSH Answers document "Infectious Waste" for information about safe handling of infectious waste.

DO NOT

• Do not mix hazardous waste with general waste materials.
• Avoid burning trash if it will be a nuisance to nearby residents.
• Do not burn green vegetation.
• Do not burn plastics, rubber, tires, or any other materials known to produce dark, irritating smoke.
• Do not add any more materials that burn slowly if a fire is producing dark smoke.
• Do not throw away unwanted chemicals into the general garbage or into bodies of water which could contaminate streams, irrigation or drinking water.

Hazardous wastes are those wastes which, due to their nature and quantity, are a potential risk to human health and/or the environment and which require special disposal techniques to eliminate or reduce the hazard. If disposed of without proper treatment, hazardous wastes can cause serious, long-lasting damage to both terrestrial (land) and aquatic ecosystems. Human health impacts can also be severe. For example, long-term exposure to mercury, lead or cadmium can damage the brain, the kidneys, the nervous system and fetal development.

In general, products that are corrosive, flammable, reactive or toxic are considered to be hazardous waste. Examples include:

• many solvents, pesticides, and paint strippers,
• materials that catch fire easily (such as gasoline, paints, and solvents);
• materials that are reactive or unstable enough to explode or release toxic fumes (including acids, bases, ammonia, and chlorine bleach); or
• corrosives that can attack metal containers such as tanks, drums, and barrels (such as industrial cleaning agents and oven and drain cleaners) or those that can attack the skin.
