23 multiple choice 1 point
why must the distribution piping and hoses used in a compressed gas system be rated for the operating pressure of the system?
to reduce the potential for a piping or hose rupture
to avoid unnecessary replacement
to ensure they are easy to disconnect
to ensure they match the other hoses in the system

Explanation:

For question 22: When using a portable compressor, its electrical rating must be evaluated to ensure it is compatible with available power sources and operates safely without electrical hazards.
For question 23: Distribution piping and hoses in a compressed gas system must match the system's operating pressure to prevent them from failing under pressure, which would cause rupture and dangerous leaks.

Answer:

1. Electrical rating
2. To reduce the potential for a piping or hose rupture
