Gruenhagen cautioned. ‘‘Never puncture an aerosol can. There is usually seme pressure left, even after the product is used up. Never throw it into a trash fire, or place the can — empty, full or partially full — near such heats as a fire, a radiator or the inside of a car on warm summer days. It can explode to harm those nearby.”
Gruenhagen continued. ‘‘Dispose of empty aerosol cans where children cannot come into contact with them. Read the labels and heed all warnings.
“Many aerosol containers look alike. Be certain you use the right one,” he urged.
