Powered air-purifying respirator (PAPR) A type of air-purifying respirator that utilizes a battery-powered fan to draw contaminated air through the cartridge or filter into the facepiece. [Pg.1468]

Responders may use full facepiece respirator with a P100 filter or powered air-purifying respirator (PAPR) with high efficiency particulate air (HEPA) filters when it can be determined that ... [Pg.104]

You can use the motor of the Powered Air Purifying Respirator (PAPR) (see entry274), keeping it on your lap to ensure a constant supply of purified air. In general, maintain a lot of distance between you and the cars in front of you and avoid rush hour traffic. Definitely have someone else fill your car with gas or wear a mask while filling up (or drive an electric car). [Pg.131]

Partially Acidulated Phosphate Rock. Not all phosphate rock is suitable for direct application and may require the addition of a more soluble form of phosphate. An alternative is partial acidulation to render its P205 more available. The partially acidulated phosphate rock (PAPR) process depends on treating ground phosphate rock with only a portion of the stoichiometric value of acid, for example 50 percent PAPR.19 The amount of water-soluble phosphate in PAPR varies according to the degree of acidulation. The crop response to the product is often quite similar to fully acidulated products such as SSP or TSR... [Pg.1133]

Powered air-purifying respirators use a blower to draw air to the user. PAPRs should not be confused with air-supplying respirators, because they do not supply clean air. The air is cleaned by cartridges or canisters, as it is with other air-purifying respirators. These respirators are available as lightweight backpacks, or they may be mounted on or in application equipment where the power is supplied by the vehicle s electrical systems. [Pg.250]

Disadvantages of a PAPR would include the inability of the respirator to be used in atmospheres which restrict the usage of any air-purifying respirator, and increased dead space (characteristic of any respirator). [Pg.567]

There is a subset of PAPRs that do not form a tight seal with the face. These are known as hood-type PAPRs. A large, loosely fitting hood usually made of a butyl rubber-coated material covers the head, shoulders, and upper chest. [Pg.568]
