When should clogged or partially filled aerosol cans be disposed?

When should clogged or partially filled aerosol cans be disposed?

• A. Immediately
• B. End of each semester
• C. After one year
• D. When full

Answer: (B)

Disposal of clogged or partially filled aerosol cans is handled through the lab’s hazardous waste program on a scheduled basis. The end of each semester is the best time because schools typically arrange hazardous waste pickup then, allowing trained staff to safely vent, label, and containerize the cans and prevent dangerous storage buildup. This approach keeps cans under proper control and reduces the risk of leaks or punctures from long-term storage. Disposing immediately isn’t advised since these cans may still be pressurized or contain hazardous contents that require a controlled process. Waiting a year is too long and increases the chance of corrosion or leaks, and waiting until the can is full ignores the fact that partial contents remain hazardous and still need safe handling.
