What is the maximum inlet pressure for a respirator in psi?

The correct choice reflects the maximum inlet pressure for a respirator, which is important for ensuring safety and proper functioning of the equipment during use. Specifically, respiratory protection standards and guidelines typically recommend that the inlet pressure should not exceed 125 psi. This limit is in place to prevent any potential damage to the respirator, maintain the integrity of the air supply system, and ensure that the user receives a consistent and safe flow of breathable air.

Selecting a pressure that exceeds this limit could compromise the effectiveness of the respirator, potentially leading to mechanical failure or an inadequate air supply, which would pose serious health risks to the user in hazardous environments. Therefore, understanding and adhering to the maximum inlet pressure is a critical aspect of proper respirator maintenance and usage.
