SOS Readiness Practice Exam

During a wildfire, smoke brings in fine particles that can irritate the lungs and worsen existing health conditions. The actions that truly reduce exposure focus on limiting the amount of smoky air you breathe: monitor the air quality index, stay indoors with doors and windows closed, and use a clean air source or a properly fitted respirator if you must be outside or in a smoky space. Creating defensible space around a home helps reduce the risk from flames and can lower smoke exposure indirectly by limiting how much smoke and heat you’re exposed to around the structure, but it doesn’t directly control the indoor air you breathe. Ignoring air quality removes a crucial cue for when to stay inside, when to seal the environment, or when to use protective respirators, leaving you vulnerable to harmful smoke levels.
