Respirator A half face particulate (air-purifying) mask is generally worn to protect the wearer from dust and paint fumes. A respirator is a device designed to protect the wearer from inhaling harmful dusts, fumes, vapors, or gases. Respirators come in a wide range of types and sizes used by the military, private industry, and the public. Respirators range from relatively inexpensive single-use, disposable masks to more robust reusable models with replaceable cartridges.

How to Choose a Respirator or Dust Mask In addition to proper ventilation, a respirator or dust mask will go a long way in protecting your lungs and health. Respirators and dust masks aren’t all the same – there are different kinds to choose from, as well as a rating system for efficiency. At home and around the workshop, either a particulate filter (dust mask) or chemical cartridge respirator are likely to be all you’ll need. N95 and R95 particulate masks.

CPAP Machines CPAPs are the most common types of machines and blow a single pressure airstream. APAPs blow a variable pressure stream dependent on the minimal pressure needed to keep user's airways open. Lastly, BiPAPs blow two separate pressure streams, one at inhalation and one at exhalation.

Respirators - Respirator Selection The main categories are: 1  N series (Not resistant to oil) - May be used in any atmosphere where there is no oil particulate.  R series (Resistant to oil) - May be used in any atmosphere where there is no oil particulate, or up to one shift where there is oil particulate present.

- 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. once the use limits are reached.

- respirator, designed to protect individuals against volatile agents and aerosols. The respirator must be carefully fitted on the face to ensure minimal leak-age, and individuals must be well trained in the donning of masks (a maximum of ≤ 9 sec being desirable). In addition to the respiratory hazard, many chemical agents are dermally active. This re-

- October 2009. Respirators and Surgical Masks: A Comparison. Because certain disposable respirators are similar in appearance to many surgical/procedure masks, their differences. are not always well understood. However, respirators and surgical masks are very different in intended use, fit. against the face, wear time, testing and approval. The purpose of this document is to highlight some of these. differences. The biggest difference between a respirator and a surgical mask is the intended use.

- APFs are numbers that indicate the level of workplace respiratory protection that a respirator, or class of respirators, is expected to provide to employees when used as part of an effective respiratory protection program.he new final rule takes effect on November 22, 2006. It includes a table of APFs (attached to this message) for the four basic types of respirators -- air-purifying respirator (APR), powered air-purifying respirator (PAPR), supplied-air respirator (SAR), and self-contained breathing apparatus (SCBA).

Thread: What kind of respirator do you use for metal work or brazing? I've done brazing a few times and done a few mitres. I've just started reading about respiratory safety. What kind of respirator/dust mask do you guys use for metal work? (Ie: filing, drilling, sanding.) I feel like an idiot for not wearing a dust mask for the two mitres I've already done, but what's done is done I suppose. In a similar vein, I want to pick up a respirator for particulate/fumes while brazing.
