Which safety equipment is crucial when working with CNG?

When working with compressed natural gas (CNG), ensuring safety is paramount due to the potential risks associated with handling high-pressure gas. The crucial safety equipment includes pressure gauges, relief valves, and gas detection systems.

Pressure gauges are essential because they allow technicians to monitor the pressure levels within the CNG system, preventing over-pressurization that could lead to leaks or other hazardous situations. Relief valves are safety devices designed to release excess pressure from the system, thereby mitigating the risk of explosion or equipment failure. Gas detection systems serve to identify any leaks in the system, which is critical since CNG is odorless and colorless; being able to detect gas presence is vital for maintaining a safe working environment.

In contrast, while reflective vests, hard hats, fire extinguishers, and safety cones are indeed important for general workplace safety, they do not specifically address the unique hazards associated with CNG operations. Standard toolkits for automotive repair, while useful for maintenance and repairs, do not provide the specialized safety features that are necessary when dealing with CNG's high-pressure properties and the associated risks.
