Which of the following indicates that a respirator meets a specific performance standard?

The indication that a respirator meets a specific performance standard is represented by its NIOSH approval. The National Institute for Occupational Safety and Health (NIOSH) establishes standards for respirators, ensuring they have been tested for their effectiveness in filtering out airborne contaminants. When a respirator is NIOSH approved, it signifies that it has met the necessary safety and performance criteria set by this regulatory body.

Brand names and warranties may suggest quality or reliability but do not specifically confirm compliance with performance standards. While color coding can assist in identifying types of respirators or levels of protection, it does not provide an assurance that the respirator has undergone rigorous evaluation or met regulatory standards. Therefore, the most definitive indicator of a respirator's performance capability is its NIOSH approval.
