
In atmospheres where the concentrations of toxic contaminants are unknown, or are Immediately Dangerous to
Life or Health (IDLH). An IDLH atmosphere is any atmosphere which has a concentration of any toxic, corrosive
or asphyxiant substance that poses an immediate threat to life, which would cause irreversible debilitating
effects on health, or which would interfere with the ability to escape from a dangerous atmosphere.

In atmospheres where the concentration of the contaminant exceeds:
I. If part of an OSHA or CSA Respiratory Protection Program:
50 times the contaminant's peoormissible exposure limit (PEL). PEL is defined as the maximum
1.
permissible 8-hour time weighted average (TWA) concentration established by applicable OSHA or
other government regulations, or by NIOSH, ACGIH or CSA.
2. Any lower Maximum Use Concentration for that contaminant established by OSHA or other
government regulations, NIOSH, ACGIH or CSA publications, or shown in the contaminant's Material
Safety Data Sheet.
II. If part of a Worksafe Australia Respiratory Protection Program:
In atmospheres where the concentration of the contaminant exceeds 50 times the contaminant's
1.
permissible exposure limit set by Worksafe Australia or other government regulations.

If part of a Brazilian Ministry of Labor (MTE) Respiratory Protection Program:
I. In atmospheres where the concentration of the contaminant exceeds 100 times the contaminant's
permissible exposure limit set by NR 15 or other government regulations.

With any filters or cartridges other than those certified for use with this facepiece by the appropriate certifying
organization.

To protect against contaminants not listed on the label for that filter or cartridge.
I. If part of an OSHA or CSA Respiratory Protection Program the label is the NIOSH Approval label included
with NIOSH approved cartridges and included with these User Instructions.
II. If part of a Worksafe Australia Respiratory Protection Program the ratings on filters and cartridges are
marked on cartridges certified to Australian and New Zealand Standards as P, A, B, E and/or K.
III. If these contaminants are included in filter or cartridge User Instructions

To protect against oil-based aerosols unless an 'R' or 'P' filter (defined by NIOSH) is used when the respirator is
used as part of an OSHA or CSA Respiratory Protection Program.

Without either an End-of-Service-Life Indicator (ESLI) on the cartridge for the gas and/or vapor present, or an
established cartridge change schedule for all gases and vapors for which there is no ESLI.

In poorly ventilated areas, or confined spaces such as tanks, small rooms, tunnels or vessels, unless the
confined space is well ventilated and the concentration of toxic contaminants is known to be, and will continue
to be, below the Maximum Use Concentration recommended for the respirator.
