Environmental impact
Why the regulation exists: ozone depletion from CFC and HCFC releases, and the climate impact of their substitutes. Core questions test whether you understand what venting actually does, which is the moral logic behind every rule on the exam.
The figures that belong to this topic
- The venting prohibition bars knowingly releasing regulated refrigerant during maintenance, service, repair or disposal.
- De minimis releases during good-faith recovery attempts are excepted.
