Flammable substances- They easily ignited. These products include paint, thinners, and other solvents. Substances that are flammable usually carry warning labels such as: Combustible; Do not smoke during use of product; Not to be used near heat or flames.
Corrosive substances- They cause disintegration of materials such as acid in car batteries. Corrosive substances usually carry warning labels such as: Causes severe burns on contact; Can burn eyes, skin, and throat.
Reactive substances- These instantly ignite or produce poisonous vapors when mixed with other substances, or can explode when exposed to heat, air, water or shock. Warning labels include: Danger; Combustible; Not to be used near heat or flames.

What do you think happens when you DON’T dispose of dangerous waste properly?
You should never put hazardous household wastes into your rubbish bins or even within your garbage collection system. These types of wastes are not to be disposed of in the sink, or toilet or gutters, or buried in the ground. This is what can happen if you don’t use correct disposal methods:
● If you bury your hazardous waste in the garden, the dangerous chemicals and poison can leach into the surface or groundwater. This can affect the soil, plants and water for a long time.
● If you pour your hazardous waste down the sink, the waste may corrode the pipes or block storm-water drains and cause problems at water treatment plants.
● If you put your hazardous waste into the garbage bins, this can put the health and safety of garbage collection workers at risk. It may also pollute waterways and drinking water if sent to normal landfills. Hazardous waste should only be stored in specially designed landfills.
● If you put your hazardous waste into plastic shopping bags, these can create an ugly litter problem if not recycled or disposed of properly. If these bags get into waterways, they may be a threat to wildlife. Most supermarkets now collect plastic bags for recycling.
Illegal disposal, dumping or misuse of wastes is a serious offence and subject to large financial penalties.

Hazardous waste is dangerous to our health and the environment. Always ensure you read labels carefully and follow the safety precautions before using any substance. It can save your life!
