A technician finishes a job and must dispose of used filter-driers and rags soaked with refrigerant oil. What is the responsible practice?
Explanation
Used filter-driers and oil-soaked materials can be contaminated and must be handled and disposed of according to hazardous-waste and local regulations, not simply thrown in the trash. Burning them or pouring oil into a storm drain releases harmful substances into the environment. Following proper disposal rules protects both the technician and the public, complementing the refrigerant recovery requirements.
