Do you ever find yourself wondering whether certain items in your house are safe to throw away in the regular trash?

If you’ve ever cleaned out your garage, or organized your storage room or shed, the answer is probably yes.

There are a surprising number of household items that contain hazardous materials, including:

  • Insect and pest killers
  • Auto oil, brake fluid, antifreeze, and other fluids
  • Bleach
  • Drain cleaners
  • Fire extinguishers
  • Batteries
  • Fluorescent light bulbs
  • Gasoline
  • Hair dye and spray
  • Lead-based and oil-based paint

  • Electronics (e-waste), many of which contain toxic materials, and are illegal to throw away in Colorado
  • Many types of cleaning products

What is Hazardous Waste?

The EPA defines any waste that can have a harmful effect on the environment or on human health as hazardous.

In general, if the packaging or label on a product lists words such as “toxic”, “volatile”, “combustible”, “poison”, “corrosive”, or “harmful”, it’s likely something you shouldn’t put in your trash.

What are the Dangers of Hazardous Waste?

Items that are described as hazardous shouldn’t be thrown out with your weekly garbage, or dumped down the drain.

The chemicals in them can pollute the soil and water. Some of them also pose a danger if handled incorrectly, with the potential to explode or burst into flame.

Fortunately, there are ways to safely dispose of or recycle of hazardous materials here in Boulder County.

How to Safely Store Hazardous Waste

We understand that you can’t take your hazardous waste to proper disposal or recycling locations every day. In the meantime, be sure to keep these items safely stored out of reach of children and pets.

Every product that contains hazardous waste is different, so first, check the packaging or label for proper storage instructions. Certain aerosols, for example, should not be stored at extreme temperatures or in particularly humid environments.

High temperatures can cause pressure in these cans to build up and potentially cause an explosion. So it’s a bad idea to keep such products in the trunk of your car in the middle of summer.

If the product emits fumes, be sure to store it in a well-ventilated area outside of your living area.

Cleaning and automotive fluids should be stored in sealed containers, ideally with a child safety cap, and out of reach of children. If possible, store such hazardous materials behind locked doors.

Regularly organize your hazardous materials, safely disposing of what you can, to minimize the risk to you and your family.
