What is the purpose of a pressure gauge in hazardous materials handling?

A pressure gauge is an essential tool in hazardous materials handling as it serves the primary function of determining the pressure within a system or container. Accurate pressure readings are crucial for ensuring safety and preventing potential hazards such as leaks, ruptures, or explosions. In a hazardous materials context, maintaining appropriate pressure levels is critical for the safe storage and transport of various substances.

By monitoring pressure, technicians can assess whether the system is operating within its designed parameters. If pressure exceeds safe levels, it may indicate a malfunction or a dangerous situation that requires immediate action. Thus, the pressure gauge is vital for ensuring the integrity of hazardous materials operations and protecting both personnel and the environment.

The other options, while related to material handling, do not define the primary purpose of a pressure gauge. For instance, measuring temperature relates to thermal conditions of materials, determining product density involves analyzing mass relative to volume, and assessing flammability pertains to the combustibility of substances. None of these functions align with the specific role of a pressure gauge.
