Warranty and Contact Information
1. General information
The SR 601 and SR 602 Hoods can be used together with
the SR 500 Powered Air-Purifying Respirator system of
components to provide respiratory protection against certain
particulates, organic vapors, acid gases and other inorganic
gases. Refer to the NIOSH Approval Label for a list of approved
components and NIOSH cautions and limitations. Before use,
these user instructions and those for the SR 500 PAPR, car-
tridges and filters must be thoroughly studied and understood.
Breathing air is supplied to the respiratory protection inlet
covering (e.g. hood) from a breathing hose connected to the fan
unit containing the appropriate canisters or filters. The pressure
generated in the hood prevents particles and other pollutants
from entering. The hood can be used in all situations for which
an air-purifying respirator is recommended. This applies
particularly to work that is hard, warm or of long duration.
The hoods protect the respiratory organs, head and shoulders.
The hoods are replaceable. They contain an impact-resistant
and chemical-resistant visor. The supply air flow keeps the visor
demisted and the airflow deflector can be directed towards
visor or face for optimal comfort. An adjustable head harness
allows for fit adjustments to improve fit and comfort. The flexible
breathing hose is replaceable. The hoods are available in one
size and offers optional protective films.
Additionally, the SR 602 is equipped with adjustable neck seal.
Limitations
• If the face seal is not firmly in contact with the face, the
pressure necessary for maintaining the correct protection
factor will not be established.

• If the user is exposed to very high work intensity, negative
pressure may occur in the device during the inhalation
phase, which may involve the risk of leakage into the
head-top.
• The protection factor may be reduced if the equipment is
used in surroundings in which high wind speeds occur.
• The seal of the head-top against the face must be assured.
This may be difficult to achieve if the user has a beard or
sideboards.
• Be aware that the breathing hose might make a loop and
get caught up by something in your surrounding.
• Never lift or carry the equipment by the breathing hose.
2. Safety Precautions
The user must read and follow all User Instructions supplied
with the SR 500 Powered Air-Purifying Respirator, respiratory
protection inlet coverings, canister or filter. Incorrect operation
of the SR 500 PAPR could result in reduced airflow, interrup-
tion of airflow to the respiratory protection inlet covering or
contamination of breathing air. For proper use: see supervi-
sor, respirator program manager, User Instructions, or for
technical support call Sundström in the U.S.A. and Canada at
1- 877- SUNDSTROM.
Failure to understand and observe the following warn-
ings and limitations may adversely affect respirator
performance and result in sickness or death
Do not use with parts or accessories other than those manu-
factured by Sundström as described in these User Instructions,
the SR 500 Powered Air-Purifying Respirator User Instructions,
or on the NIOSH Approval Label for the SR 500 PAPR system.
The U.S. Occupational Safety and Health Administration
(OSHA) Standard 29 CFR 1910.134 and the Canadian CSA
Standard Z94.4 require a written respirator program and
appropriate training before occupational use of this respirator.
The hoods do not provide eye and face protection. When
exposed to eye and face hazards, the respirator wearer must
wear eye and/or face protectors appropriate to the hazard.
Do not use these respiratory protection inlet coverings and the
SR 500 Powered Air-Purifying Respirator in atmospheres for
which they were not designed or certified by NIOSH including:
– Oxygen deficient or enriched atmospheres.
– Where contaminant concentrations are unknown or are
Immediately Dangerous to Life or Health (IDLH).
– Where maximum contaminant concentrations mandated by
specific government standards are exceeded.
Before you enter a hazardous atmosphere wearing the SR 500
Powered Air-Purifying Respirator, you must inspect the SR 500
PAPR fan unit and components of the respirator, complete a
user performance check, and don the respirator according to
the SR 500 PAPR User Instructions and these User Instruc-
tions. Always properly don this respirator in an area where the
air is clean before entering a hazardous atmosphere.
