The NIOSH/DHHS approval label for each product lists limitations and requirements. All current NIOSH/
DHHS labels can be found in the respirator box printed on a sheet titled Section "VIII NIOSH/DHHS
LABELS" of this manual. The Sundström P100 filter can be combined with each chemical cartridge to
give the user combined vapor, gas and particulate protection.
E. What does the pre-filter do?
The Sundström pre-filter can only be used with a cartridge or P100 filter to reduce nuisance dusts. This
extends the life of the protective element by capturing these large particulates, preventing premature
loading of the primary protective elements. This pre-filter is not a protective element.
The Sundström pre-filter is a thin filter that does not have any printing on either side.
F. What if I can't smell anything, or I don't mind the smell?
The physiological damage from some contaminants can be long term and many take months to ap-
pear. The danger from these hazards may be masked by an unfamiliar or even pleasant odor. A certain
smell or odor may not bother you, or cause you discomfort, but the contaminant can still be hazardous.
G. When do I change the filter or cartridge?
Chemical Cartridge – Loss of protection is frequently detected when the user experiences
BREAKTHROUGH.
If you experience any one of the following danger signals leave the hazardous area immediately,
return to fresh air. Check your respirator, and replace the protective element if necessary: and seek
any necessary assistance.
a. Breathing difficulty, dizziness or nausea, smell
b. Dizziness or nausea
c. You smell or taste the contaminants
d. Any other noticeable physical effect
If you smell, feel or taste anything unusual leave the contaminated area, check your respirator, and
replace the protective element if necessary. In some atmospheres breakthrough may be hard to detect
or may occur too late to provide you a safe exit from the contaminated atmosphere. An air-purifying
respirator is not appropriate for use. However under certain conditions, the chemical cartridges can be
used but must be changed after a specific exposure time. This schedule is set by a competent authority
and controlled by your safety professional.
An exhausted chemical cartridge will allow hazardous fumes or vapors to pass through to
the user who may not notice any change in breathing resistance. Follow local procedures
and all warnings contained in the users manual.
