Aerosol Spray (AS)

Aerosol sprays contain a pesticide and a propellant that are packed under pressure. When the nozzle is pressed, the product and propellant are released from the container in a fine mist or directed spray.

Due to the following hazards associated with aerosols, less hazardous options are recommended where available.  

Aerosol spray formulations do not meet our criteria for least-toxic and should always be used with special precautions, see below.

Hazards

• Breathing the propellant, pesticide or other ingredients can be hazardous to health. 

• Aerosol cans containing propellant are explosive if crushed or heated.

• Aerosol propellant can be flammable. Use away from heat or sparks.

• A misdirected spray can cause eye injury and chemical burns.

• Acute symptoms of aerosol exposure include headache, nausea, dizziness, shortness of breath, throat irritation and skin rash. 

Precautions

• Store aerosol products according to all product label recommendations.

• Never place an aerosol can near  a heater, direct sunlight, fire or other heat source.  Heat causes the propellants to expand, which may result in an explosion.

• Never puncture or subject an aerosol can to sharp impact. A puncture may cause an explosion.

• Never place an aerosol can in a household trash compactor.  The pressure may cause an explosion.

• Never throw a full or partially full aerosol can into the regular trash. Refuse collectors may be injured by exploding cans and/or be sprayed with hazardous chemicals.

• Keep aerosol cans away from children and pets. 

• Dispose of aerosols properly. If an aerosol can is completely empty, it can be disposed of in the regular trash.  Some communities accept the cans as part of their metals recycling program. 

• If an aerosol product cannot be used, given away for reuse or if the nozzle is broken, take it to a household hazardous waste collection facility or event.

• Always wear proper personal protective equipment such as goggles, respirators and gloves.

• Never apply pesticides when unprotected individuals or exposed food or eating utensils are nearby.

• Always clean up spills immediately.
