What are the 3 types of respirators?

The three basic types are: Half Mask/Dust Mask, Half Mask (Elastomeric), and Full Facepiece (Elastomeric). 2. Non-Powered Air-Purifying Respirators: When using a non-powered air-purifying respirator, the user operates it simply by breathing.

What are the different respirator masks?

The many types of respirators available include (1) particulate respirators, which filter out airborne particles; (2) “gas masks,” which filter out chemicals and gases; (3) airline respirators, which use compressed air from a remote source; and (4) self-contained breathing apparatus, which include their own air supply.

What is a half mask air-purifying respirator?

PAPRs are generally more protective than non-pow- ered half mask respirators because the blower creates positive pressure inside the facepiece under most work conditions, which reduces inward leakage of potentially contaminated air. A half facepiece PAPR has an APF of 50, and a full facepiece PAPR has an APF of 1,000.

Where do you put a quarter mask respirator?

Quarter mask respirators are used with cartridges or cloth filters. The quarter mask fits from the top of the nose to the top of the chin. The breathing resistance is high in comparison to larger masks. Half-mask respirators fit from under the chin to above the nose. One or two cartridges are used to filter the air and are

What’s the difference between a face mask and respirator?

A respirator is a tight fitting mask that creates a FACIAL SEAL. Each respirator when used properly will create a facial seal which will provide TWO-WAY PROTECTION, filtering the air entering and exiting the wearer at a level of efficiency designated by the respirator or filter/cartridge (Half Face and Full Face).

When to use a half mask negative pressure respirator?

Therefore, OSHA standards require to restrict using of half-mask negative-pressure respirators up to 10 PEL after obtaining fit factor greater than or equal to 100 during the mask selection for the worker (they used a safety factor = 10). Comparison of APF in the US and the UK

Are there any NIOSH approved surgical mask respirators?

Surgical N95 – A NIOSH-approved N95 respirator that has also been cleared by the Food and Drug Administration (FDA) as a surgical mask. N99 – Filters at least 99% of airborne particles. Not resistant to oil. N100 – Filters at least 99.97% of airborne particles. Not resistant to oil.
