Can supplied-air respirators only be equipped with demand pressure regulators?

1. True

2. False

3. Only for low-risk environments

4. Only with special adaptations

The correct answer is: False

Supplied-air respirators are designed to deliver breathable air from a source to the user, and they can be equipped with various types of pressure regulators, not just demand pressure regulators. The flexibility in design means that supplied-air respirators can use continuous flow or pressure-demand regulators, depending on the specific requirements of the environment and the level of protection needed. This adaptability allows for safe and effective use in a variety of situations, including high-risk environments where additional respiratory protection might be necessary. By offering multiple options, users can select the most appropriate system for their circumstances, ensuring optimal safety and effectiveness during operations involving hazardous materials or conditions.
