1. I TRODUCTIO
This device is one component of a North air-purifying respirator. The
attachment of a pair of suitable filters from the North 7500 series will
provide respiratory protection against hazardous vapours, gases
and/or particulate matter, depending on the filters used and the conta-
minant concentration and/or toxicity; provided there is sufficient oxy-
gen present in the contaminated atmosphere to support life.
A choice of three sizes of facepiece and a wide variety of filters are
available.
1.1 IMPORTA T I FORMATIO
This Operating and Maintenance Instruction Manual contains impor-
tant information and must be completely read and understood by all
persons who may use or maintain this respirator.
This Respirator should be used or maintained only by persons who
understand the instructions contained within this manual.

WAR I GS
1. Failure to properly select the appropriate respirator for all the
contaminants and their concentrations against which protec-
tion is required, or a failure to follow North’s instructions and
warnings, may result in exposure to the hazardous materials,
causing serious illness, disability or death of the affected
worker.
2. Do not use this respirator for protection against air contami-
nants other than those listed on the instructions which accom-
pany each filter. If in any doubt, contact your local distributor.
3. Do not use this respirator under any of the following conditions:
• While performing or observing abrasive blasting (sand-
blasting) operations.
• For fire fighting.
• For protection from fumigants.
• In oxygen-deficient atmospheres (any atmosphere having
less than 17% oxygen by volume at sea level).
• In atmospheres where the concentrations of toxic contami-
nants are unknown, or are IDLH. (An IDLH atmosphere is an
atmosphere which has a concentration of any toxic, corro-
sive 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 contami-
nant exceeds the respirator’s Maximum Use Concentration
listed in the table below;
