Field notes on tear gas and bear spray residue

Each note answers one question. Why do symptoms flare when the furnace kicks on? How does capsaicin oil behave differently from CS powder? What happens to a soaked car seat, and who pays when a rental gets tear-gassed? They're written for households and small businesses around Berkeley.

  1. Why CS tear gas powder keeps stinging long after the cloud clears The name says gas, but CS is a solid that is dispersed as tiny particles. Once the cloud settles, those particles sit on every surface and in every fabric they reached, and they wake up again whenever they are disturbed.
  2. Capsaicin oil versus CS powder: why the cleanup is not the same People lump bear spray, pepper spray and tear gas together because they all burn. One is a dry powder and the other an oil, and a cleanup plan that works on one can smear the other around.
  3. The first furnace run after tear gas, and why it can undo a week of airing out Households often air out a house, feel better, and then get hit again the first cold night the furnace starts. The heating system is a reservoir and a delivery system for residue at the same time.
  4. Ducts, filters and coils after tear gas or pepper spray exposure The heating and cooling system is the part of a home most likely to keep spreading residue after surfaces look clean. Knowing which components collect it helps you judge whether a proposed scope leaves gaps or adds padding.
  5. When bear spray goes off inside a hot car Colorado drivers carry bear spray to trailheads all summer, and a closed car in the sun gets far hotter than the air outside. A can that vents or is triggered by a loose item can coat an entire cabin in minutes.
  6. Getting capsaicin out of a vehicle's cabin filter, vents and seats Car owners often clean the visible surfaces and then get a face full of pepper the next time they switch on the heater. The ventilation system needs its own attention, and so does each type of interior material.
  7. Bear spray in an attached garage, and keeping it out of the house Garages are where Colorado households keep camping gear, including bear spray. When a can falls or vents there, the problem rarely stays in the garage: it follows air through the house door, attic connections and the people walking in.
  8. Keep or replace? Soft goods after tear gas or pepper spray Hard surfaces can almost always be washed. Absorbent items are the real judgment call, and they are also where most of the cost and the arguments with insurers tend to land.
  9. Laundering clothes and bedding that carry tear gas or capsaicin Most washable fabrics can be saved, but the laundry room is also where residue spreads to everything else. A few habits keep one contaminated load from turning into a house full of irritated skin.
  10. Protecting your skin, eyes and lungs around irritant residue Even a quick trip back inside to grab medications or documents can leave people coughing for hours. Basic protection and a plan for first aid make short entries safer, and they matter even more for anyone who chooses to do some cleaning.
  11. When children and people with asthma can move back in after tear gas Adults may tolerate a little leftover sting. A toddler crawling on carpet, or a parent with asthma, may not. Re-entry for the most sensitive household members deserves a higher bar and a slower pace.
  12. Ozone, foggers and air fresheners: why they miss the real problem The burning after tear gas or bear spray comes from particles and oil on surfaces, not from a smell in the air. Products that change the smell can hide the warning sign while leaving the irritant behind.
  13. Tear gas residue in older northwest Denver bungalows Much of Berkeley and the blocks around it were built up in the early twentieth century with brick and frame bungalows. Their materials hold residue differently than drywall and laminate, and some need gentler handling.
  14. Renters and landlords after tear gas is used in a rental Rentals are common in Berkeley, Regis and Sunnyside. When police use tear gas in or next to a rented unit, the owner, the tenant and possibly two insurers each have a piece of the problem, and the pieces do not always fit neatly.
  15. Filing an insurance claim after police use tear gas in your home Coverage for tear gas cleanup is not settled across carriers. Some homeowners have been paid; others have been told the loss falls under an exclusion. Prompt reporting and careful records make a difference either way.
  16. Pepper spray released inside a small business Neighborhood commercial strips around Berkeley and the Highlands are full of small shops, cafes and bars. A pepper spray discharge during a dispute or a theft can clear a room instantly and raise questions about food safety, stock and when to reopen.
  17. What to note about residue on hard surfaces Hard surfaces are the easiest part of an irritant cleanup, as long as the method matches the residue. Dry powder and oily spray need different first steps, and the wrong one spreads the problem.
  18. Tear gas in a shared building: which rooms, and whose job In a multi-unit building, irritant residue does not respect unit lines. Corridors, stairwells and shared ventilation spread it, and each unit, the association and several insurers may each own a piece.
