Great point! So if you have a firework that sparks some dry grass or brush, your home fire extinguisher will likely be fine as long as the fire doesn’t get too big before you can grab it.
However, if you have a hoard of fireworks that catch fire, you’re better off running and calling the fire department than trying to quickly put that out with your home fire extinguisher as it likely won’t work.
Those years of safety training finally paying off:
Do you know what types of fires your fire extinguisher is rated for? There are several different types. Most modern home fire extinguishers are rated for A (wood/paper), B (liquids like oil fires), and C (electrical), but you may have an older fire extinguisher or landlord who cheaped out on one that only works on some of those types.
If you have a fire that’s based on metals (like fireworks) or exothermic chemical reactions, have a different fire extinguisher or call the fire department with special instructions.
Always remember the acronym PASS when using a fire extinguisher:
Volume changes based on temperature and pressure. So when we reference volume measurements like for flow rates, we typically do the math to adjust those to standard temperature and pressure. Standard pressure is 1 atm but standard temperature varies based on who you’re talking to because of competing standards. It’s usually 25 C or 20 C.
When we want to reference the non temperature and pressure corrected volume, we append actual to it so that people know what the measurement is. Some people don’t do that and that causes confusion for others using their work if the reading is standard or actual.
