Negative-pressure air-purifying respirator

Generally negative-pressure air-purifying respirators tend primarily to increase respiratory work that may then later have a ripple down effect to increase cardiac work in individuals with metabolic compromise. [Pg.559]

PHOTO 20.29 Inside view of M40A1 mihtary negative-pressure air-purifying respirator (gas mask). Note-. The inside surface of the respirator would be in direct contact with the responder s face, and thus establish the vapor-proof water seal (derived from the responder s perspiration) between the respirator and the responder s face. When the respirator is worn by the responder, the free edge of the reversed seal would fold forward into the body of the facepiece of the respirator as the head straps are tightened by the responder. (Author s personal photograph taken by him.)... [Pg.606]

QLFT may only be used to fit test negative pressure air-purifying respirators that must achieve a fit factor of 100 or less. [Pg.729]

In certain cases, to provide sound medical advice to the employer and the employee, the physician must evaluate situations not directly related to EtO. For example, employees with skin diseases may be unable to tolerate wearing protective clothing. In addition those with chronic respiratory diseases may not tolerate the wearing of negative pressure (air purifying) respirators. Additional tests and procedures that will help the physician determine... [Pg.1153]

A. Qualitative Fit-Testing (QLFT) may be used to fit test negative pressure air-purifying respirators, if they will only be used in atmospheres less than ten times the PEL, since existing evidence only validates the QLFT protocols listed in Appendix A to identify respirators that achieve a fit factor of 100. [Pg.1384]

Can a qualitatively fit-tested tight-fitting negative pressure air-purifying respirator be used in an atmosphere greater than 10 times the permissible exposure limit (PEL) ... [Pg.315]

Negative-pressure air purifying respirators that will be worn in concentrations that are equal to or less than ten times the PEL may be fit-tested using QLFT. [Pg.316]
