scope:

This Japanese Industrial Standard specifies the powered air purifying respirators for particulate matter (hereafter referred to as PAPRs) used at the workplaces and other locations under the environment that may cause harmful effects on a human body due to the inhalation of particulate substances floating in air (hereafter referred to as the dust and the like).

This Standard is basically applicable to the conditions in which an electric fan of PAPR operates normally. The facepiece-type PAPR assumes the continuous use as a filtering device in the case where an electric fan is stopped due to the battery exhaustion and the wearer needs to move to the safe place, or an electric fan is intentionally stopped by the reason of the work.

WARNING 1 Do not use PAPR under the oxygen deficiency environment.

WARNING 2 Do not use PAPR in a place where a toxic gas or vapour, or volatile mist exists.

WARNING 3 Do not use PAPR under the environment in which an explosion may occur, unless it is proved as the explosion-proof electrical apparatus.

WARNING 4 Select PAPR correctly based on the type and concentration of the dust and the like.

Criteria for the selection of suitable respiratory protective devices are specified in JIS T 8150.
