scope:

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

WARNING 1 Do not use a particulate respirator under the oxygen deficiency environment.

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

WARNING 3 Do not use a replaceable type particulate respirator equipped with an inhalation assisting device under the environment in which an explosion may occur, unless it is proved as the explosion-proof electrical apparatus. WARNING 4 Select the particulate respirators 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.
