What environmental precautions should be observed after completing a tightness test?

• A. Properly close out test area, prevent vapor release, and remove equipment while following spill prevention practices.
• B. Leave the area open to ventilation and ignore spills.
• C. Discard all test equipment immediately.
• D. Increase test pressure to ensure leaks are visible.

Answer: (A)

After finishing a tightness test, the environmental priority is to secure the area and prevent any vapor releases or spills from contacting soil, water, or air. Closing out the test area, controlling and containing residual vapors, and removing equipment with spill-prevention measures stops contaminants from escaping and protects the environment. Proper teardown and removal reduce the chance of leaks or drips that could contaminate nearby surfaces or waterways, and it ensures any remaining liquids are collected and disposed of safely. Ventilation is important, but it must be paired with containment and cleanup so vapors don’t disperse uncontrolled. The other options miss these protections: leaving the area to ventilation and ignoring spills allows vapors to escape and increases environmental and safety risks; discarding equipment immediately bypasses necessary decontamination and containment steps; and increasing the test pressure creates new hazards rather than addressing environmental precautions.
