Respiratory Protective Equipment
Types of RPE:
1-Respirator: Designed to purify respirable air by inhaling it through a medium which removes the contaminants. All respirators are designed on Negative Pressure.
• Face-piece Respirator (Dust Mask)
• Half-mask Respirator
• Full-face Respirator
• Powered Visor Respirator
2-Breathing Apparatus: Supplies pure respirable air from an uncontaminated source. All breathing apparatuses are designed on positive pressure.
• Emergency Escape Set
• (BA) Breathing Air-line Trolley
• (SCBA) Self Contained Breathing Apparatus
