University City Tear Gas Cleanup: Common Questions Answered
What is the difference between tear gas and pepper spray?
Tear gas is a group of irritant agents, usually fine solids, such as CS, CN and CR. Pepper spray, or OC, is made from chili pepper extract in an oil base. They behave differently, so cleanup methods differ.
What can be saved after tear gas?
Glass, metal, sealed wood and plastic often clean well. Washable fabrics may be saved depending on the agent. Carpet, padding, foam and mattresses are harder, and some must be removed. The crew sorts items with you.
Why does the air system matter?
If the heating or cooling system ran, it may have pulled irritant particles into vents and ducts and moved them to other rooms. Crews isolate and clean the system so residue does not spread again.
Can I clean tear gas residue myself?
Small incidents with little residue may clear with fresh air. For anything larger, it is risky because residue is hard to see and wiping can spread it. A professional crew uses protective gear and checks the result.
What should I do first after tear gas is released?
Get to fresh air, take others and pets with you, and keep everyone out of the space. Do not hose it down or mix cleaning products. If anyone has trouble breathing, call 911 or Poison Control.
How long does tear gas cleanup take?
A small space can be finished quickly, while a whole building, or one where the air system ran, takes longer. The team gives a timeline after seeing the site. Keep the space closed until the work is done.
