검증된 단계별 안내1
Understand that reclaimed refrigerants are those that have been recovered from equipment and processed for reuse.
Recognize that during use and recovery, refrigerants can degrade or become contaminated with impurities or breakdown products.
These impurities or breakdown products can be toxic or harmful to human health and the environment.
Because of these potential hazards, reclaimed refrigerants are classified as hazardous materials to ensure proper handling, storage, and disposal.
Note that not all reclaimed refrigerants are flammable or inert; their classification depends on their chemical composition and contamination.
