Chemicals are now being used to clean the streets after fires.
The US Environmental Protection Agency (EPA) said it would use chemicals as a “last resort” to reduce the risk of further fire damage.
The agency said the chemicals would be applied to a patch of grass to help fight the spread of the fire.
EPA Administrator Gina McCarthy said the move was to help stop the spread.
What are chemicals? “
As the risk to public health continues to increase, the EPA is taking a new approach that will help protect communities and our environment from further wildfires.”
What are chemicals?
Chemicals can be used to kill or injure insects, such as fleas and ticks, but can also kill plants.
The chemicals are usually sprayed onto the surface of a burning area or into the ground to extinguish the fire, but they can also be used as a means to protect against insects, insects that are carried in soil, or even a wildfire.
The chemical that will be sprayed onto a patch is called an organic compound (OC).
The chemicals can also harm people or animals.
Some are poisonous.
They can cause eye, nose and throat irritation, vomiting, stomach pain, muscle aches, headaches, difficulty breathing and skin reactions.
Other chemicals can cause skin irritation, burns, or death.
