As a former Volunteer FireFighter I am conscious of this matter.
Do you keep all pressurized spray cans localized in a cabinet?
Are all 'flammables', ie, thinners, solvents, etc. stored in a metal locker?
Do you use a safety can for your wiping materials, rags, paper towels, etc.?
A friend and neighbor is on our local FireFighting service and he has even placed an 'Alert' in the system that shows I have flammables stored in my garage so the response team knows what they are facing if they have to come.
Please review your Fire Safety measures for the protection of you, your family and your FireFighters!
