Regulations & Safety第 80 / 240 题
A technician finishes a job and must dispose of used filter-driers and rags soaked with refrigerant oil. What is the responsible practice?
a.Toss them in the regular trash immediately
b.Burn them on-site to save space
c.Pour any residual oil down a storm drain
d.Handle and dispose of oil-contaminated materials according to hazardous-waste and local regulations
解析
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.
