Aerosol Can Safety Usage Tips

1. Correct Storage: Avoid High Temperature and Violent Collision

• Store in a cool, dry, and well-ventilated place, away from direct sunlight, stoves, heaters, and other heat sources. The storage temperature should not exceed 50℃ to prevent the internal pressure of the can from rising sharply due to heat, which may cause explosion.
• Do not place aerosol cans in closed spaces with high temperature, such as car trunks, attics, or greenhouses. In summer, the temperature inside the car trunk can easily exceed 60℃, which is a high-risk area for aerosol can explosion.
• Avoid violent collision, falling, or trampling on the can body. Impact may damage the can body structure or valve system, leading to propellant leakage or sudden pressure release.
• Store upright and do not place horizontally or upside down for a long time, especially for cans with liquid contents. This can prevent the propellant from mixing abnormally with the contents and avoid affecting the spraying effect or causing valve blockage.

2. Standard Operation: Ensure Safe Spraying

• Before use, check the can body and valve for damage, deformation, or leakage. If there is any abnormality (such as rust, dents, or gas leakage), stop using it immediately and dispose of it properly.
• Shake the can fully 3-5 times before spraying (especially for products with suspended particles or layered contents, such as sunscreen sprays and insect repellents) to ensure uniform mixing of the contents and propellant, and improve the spraying effect.
• Maintain an appropriate spraying distance: For daily chemical products (such as sunscreen sprays, air fresheners), the distance from the target surface should be 15-25cm; for cleaning agents and industrial products, it should be 20-30cm. Avoid spraying too close to prevent local accumulation or splashing.
• Do not spray towards open flames, high-temperature objects, or electrical equipment (such as stoves, lit cigarettes, power sockets). Most propellants are flammable, and spraying near fire sources may cause combustion or explosion.
• Use in a well-ventilated environment. Do not spray in closed small spaces (such as narrow bathrooms, storage rooms) for a long time to avoid excessive accumulation of propellant gas, which may cause dizziness, chest tightness, or even fire hazards.
• Do not spray directly on the skin or eyes. If the sprayed substance comes into contact with the skin, rinse immediately with plenty of water; if it enters the eyes, rinse with clean water for at least 15 minutes and seek medical attention promptly.

3. Proper Disposal: Avoid Environmental Pollution and Safety Risks

• Do not puncture, crush, or burn the aerosol can, whether it is empty or has remaining contents. Puncturing or crushing may cause the can body to burst due to sudden pressure release; burning will cause the internal pressure to rise sharply, leading to violent explosion.
• For cans with remaining contents, do not arbitrarily discard them in domestic waste. Contact local environmental protection departments or professional recycling institutions to hand over the cans for centralized treatment. Some communities have special recycling points for hazardous waste, which can be used for disposal.
• When discarding empty cans, confirm that there is no residual pressure inside (press the nozzle to check if there is any gas spraying). After confirming that it is empty, it can be disposed of according to ordinary metal recycling standards, but it is still recommended to hand it over to a professional recycling institution.

4. Special Groups and Special Scenarios: Additional Safety Reminders

• Keep aerosol cans out of the reach of children and pets. Children may mistakenly press the nozzle or play with the can body, leading to accidental spraying or can body damage.
• For pharmaceutical aerosol cans (such as asthma sprays), strictly follow the doctor's advice and the instructions on the can for use. Do not increase the dosage or use frequency at will, and pay attention to the expiration date of the product.
• When using industrial aerosol cans (such as rust inhibitors, spray paints), wear appropriate protective equipment (such as gloves, goggles, masks) to avoid direct contact with the skin or inhalation of harmful gases.
