NGA 29/30 Repairing a Distribution Pipe Practice Test

When making temporary repairs on plastic pipe using clamps, preventing static discharge is crucial because plastic materials can accumulate static electricity. This can lead to sparks or discharges that may ignite nearby flammable substances or create hazards in environments where flammable gases or vapors may be present.

Static electricity can build up due to the friction between the plastic pipe and the clamp or from environmental factors. By ensuring that precautions are taken to prevent static discharge, you help ensure a safe working environment during the repair process.

In contrast, using a hammer to secure the clamp would risk damaging the pipe or compromising the integrity of the repair, and applying excessive force to tighten the clamp can also lead to cracking or breaking of the plastic pipe. Similarly, while sealants might be beneficial in certain scenarios, they are not a fundamental precaution related to the specific risks of static electricity during the clamp installation.
