Details :
Principles of Operation :
These respirators are designed to
maintain a slight positive pressure of air inside the facepiece
whether the wearer is inhaling or exhaling. This helps prevent
contaminants from seeping in around the facepiece, even if there
should be small breaks in the face-to-facepiece seal.
Approvals & Standards :
The MSA Pressure-Demand Air-line
Respirator has received National Institute for Occupational
Safety and Health (NIOSH) and Mine Safety and Health
Administration (MSHA) Certification No. TC-19C-158, for use in
atmospheres not immediately dangerous to life and health and
from which the wearer cannot escape without the aid of a
respirator. MSA Air-Supply Hose (25-300 feet) must be used to
maintain NIOSH/MSHA certification. The units require an air
supply from an uncontaminated compressed-air source as
stipulated in General Industry Safety and Health Regulations,
Part 1910.134 (OSHA) with the delivered air conforming to at
least Grade D of ANSI Standard Z86.1.
