Examples of Household Hazardous Waste

Hazardous wastes can be found throughout the home. Look for labels on the items - words such as DANGER, WARNING, and CAUTION are signals for hazardous waste. Look in the kitchen, bathroom, basement and garage for them. 

Proper disposal of these and any other hazardous waste is important to the safety of your family and household pets, as well as the quality of our environment. Reduce the risk of poisonings, fires, and toxic fumes by properly disposing of such materials at the SEMCO Regional Collection center or one of our conveinient satellite locations. Never dispose of hazardous chemicals directly into your garbage or into the waterways of your community.

Products that contain the following chemicals are hazardous: corrosive, explosive, reactive, flammable or toxic. Unfortunately, the absence of the words does not guarantee the product is without hazards. For example, methyl alcohol (found in some glass cleaners) can cause blindness if ingested, but may not require a warning if it makes up less than 4% of a product. Additionally, health effects from long term exposure may not even be considered in the labeling requirements.
