Rest your palm flat on the aerosol can at the back of your shed at 3pm and hold it there: it’s the check fire crews make first
Fire crews have a simple trick to check if your shed’s aerosol cans are in danger: press your palm flat against them at 3pm on a hot day. If the metal feels uncomfortably hot, the pressurized gas inside could be building toward dangerous levels. This seemingly innocent can of fly spray or WD40 could become a serious hazard when summer heat transforms your shed into an oven.
