Basic protection
- Hands
- Nitrile gloves, changed when torn or heavily soiled; avoid latex if allergic
- Eyes
- Sealed goggles rather than ordinary safety glasses; no contact lenses
- Breathing
- A well-fitted particulate respirator for CS dust; ask a professional about cartridge respirators for heavy spray residue
- Body
- Long sleeves and pants, or disposable coveralls, removed outdoors
- Feet
- Shoe covers or dedicated shoes left at the door
Before going inside
- Decide exactly what you need to retrieve and where it is, so time inside is short.
- Open doors and windows from outside first if possible, and let air move before entering.
- Tie back long hair and remove jewelry that could trap residue against skin.
- Have clean water, mild soap and a clean towel ready outside.
- Bring a bag for contaminated clothing and gloves.
- Make sure someone outside knows you are going in.
First aid basics after contact
General guidance only. Follow advice from Poison Control or a clinician when you have it.
Move to fresh air
Leave the area and face into the breeze. Most mild symptoms ease with time in clean air.
Flush eyes with water
Rinse with clean, cool water for several minutes, keeping eyelids open. Do not rub. Remove contact lenses if they are in.
Wash skin with soap
For capsaicin oil, soap or a mild dish detergent and cool water work better than water alone. Avoid hot water, which can intensify burning.
Change clothes outdoors
Peel clothing off away from the face, bag it, and shower before touching household items.
Watch for delayed symptoms
Coughing or chest tightness that develops later deserves a call to a clinician.
The limits of doing it yourself
Household protection is designed for short, light tasks. A home where police deployed multiple canisters, or a garage coated by a full can of bear spray, involves hours of close work in residue, and the exposure adds up. That is the point where many households hand the job to a cleanup provider with proper respiratory equipment and keep their own role to documentation and decisions.
If you do clean, take breaks outdoors, work one room at a time, and stop if symptoms build rather than pushing through.
