What is prohibited regarding recovered halocarbons used as clean agents?

• A. Recovered halocarbon clean agents shall not be released into the atmosphere.
• B. Recovered halocarbon clean agents should be vented to the atmosphere after neutralization.
• C. Recovered halocarbons clean agents can be disposed in the municipal waste stream.
• D. Recovered halocarbon clean agents may be released if properly filtered.

Answer: (B)

Recovered halocarbons used as clean agents are environmental hazards that must be kept from being released into the atmosphere. After they are recovered, these substances should be returned to the supplier or sent to a licensed reclamation or destruction facility, following regulatory requirements. The action described—venting to the atmosphere after neutralization—is prohibited because releasing halogenated agents, even after any neutralization step, can still harm the ozone layer and the environment, and improper disposal through air release is not allowed. Municipal waste disposal or releasing after filtration are also not acceptable paths; the proper approach is containment and processing through approved reclamation or disposal channels.
