REUSABLE RESPIRATOR

Reusable Respirator are recommended in a workplace where harmful gases or vapors, in addition to particulates.

Unlike disposable masks, a filter or cartridge is directly
mounted to an independent facepiece and
replaced upon the end of its lifecycle.

Covers the entire face

Covers around the nose and mouth only

Mount a vapor cartridge to use as a cartridge respirator.

Special

※ However, visor filtration-type special grade filters are not to be used for handling carcinogenic substances,
such as asbestos.

1st

· Environments containing particulates other than the ones that require special grade masks.
· Environments containing particulates generated by heat, such as metal fumes.
· Environments containing mechanically generated particulates.
(Excepts in cases for particulates such as Silicon, where 2nd grade masks are permissible)

2st

· Environments containing particulates other than the ones that
require special or 1st grade masks

Recommended Applications for Vapor Cartridges by Grade
Grade	Applications
High concentration	Gas or vapor concentrations below 2% (3% for ammonia)
Medium concentration	Gas or vapor concentrations below 1% (1.5% for ammonia)
Low/lowest concentration	Gas or vapor concentrations below 0.1% Not for emergency

※ Use a cartridge respirator where the oxygen concentration is >18% and facepiece
(SCBA/Reusable) in case of medium/high concentration.

※ Inward leakage: <0.05% for full facepiece and <5% for half facepiece

Vapor Cartridge Colors by Gas Type
Gas	Color Coding for Cartridges	Harmful Substances
Organic compounds	Brown	Gas or vapor of organic solvent
Halogen Hydrogen sulfide Hydrogen cyanide	Gray	Halogen gas or vapor Hydrogen sulfide gas Hydrogen cyanide gas or cyanide vapor
Sulfurous acid	Yellow	Sulfurous acid gas or vapor
Ammonia	Green	Ammonia gas or vapor

· It should be appropriate for the task.
· Use a supplied air respirator when working in a place with an oxygen concentration of less than 18% and toxic gas concentration of less than 2% (3% for ammonia) or working over an extended time.
· Replace immediately after the breakthrough time specified in the instruction manual.
· Keep sealed in a cool place.
· Follow the instructions on how to care for disposable respirators for the facepiece, exhaust valve, etc.
Breakthrough time: The time until toxic gases pass through without being filtered.
