1. General information
Use of a respirator must be part of a respiratory protection
program. For advice see EN 529:2005. The guidance contained
in these standards highlights important aspects of a respiratory
protective device program but does not replace national or
local regulations.
If you feel uncertain about the selection and care of the
equipment, consult your work supervisor or get in touch with
the sales outlet. You are also welcome to get in touch with
the Technical Service Department at Sundström Safety AB.

1.1 System description

SR 580 together with the fan unit SR 500/SR 500 EX/
SR 700 and approved filters is included in the Sundström
fan-assisted respiratory protective device system conforming
to EN 12941:1998 (fig. 2). SR 580 can be used together with
fan unit SR 500 EX in explosive atmospheres.
The breathing hose must be connected to the fan unit equipped
with filters. The above atmospheric pressure generated in the
head-top prevents particles and other pollutants from being
admitted into the breathing zone.
SR 580 can also be used together with compressed air
attachment SR 507 (fig. 1). This combination forms a breathing
apparatus designed for continuous air flow, for connection to
a compressed air supply in accordance with EN 14594:2005.

1.2 Applications

The SR 580 together with fan SR 500/SR 500 EX/SR 700
or SR 507 compressed air attachment can be used as an
alternative to filter respirators in all situations in which these are
recommended. This applies particularly to work that is hard,
warm or of long duration. When selecting the head top, some
of the factors that must be taken in to account are as follows:
• Type of pollutants
• Concentrations
• Work intensity
• Protection requirements in addition to respiratory protective
device.
The helmet/visor must only be used when carrying out work
it is intended for. The helmet provides limited protection by
reducing the force of falling objects that strike or penetrate the
top of the helmet shell.
The visor provides protection for the eyes and the face from
various hazards such as flying objects, impact, splashes and
airborne debris.
The risk analysis should be carried by a person who has
suitable training and experience in the area.
1.3 Warnings/Limitations
Note that there can be national differences in the regulations
for use of respiratory protective equipment.

SR 580 Helmet with Visor
Warnings
The equipment must not be used
• If the fan is not running. In this abnormal situation, the
equipment will provide no protection. In addition, there is
risk of carbon dioxide quickly accumulating in the head top,
which would lead to oxygen deficiency
• if the pollutants are unknown,
• in environments that are immediately dangerous to life and
health (IDLH),
• in environments where the ambient air is oxygen-enriched
air or does not have a normal oxygen content,
• if you find it difficult to breathe,
• if you smell or taste pollutants,
• if you experience dizziness, nausea or other discomfort.
Materials that come into contact with the skin of sensitive
people may cause allergic reactions.
Damaged or scratched occulars must immediately be replaced.
Eye-protectors against high-speed particles worn over stan-
dard ophthalmic spectacles may transmit impacts, thus
creating a hazard to the wearer.
When hearing protectors is used, the requirement for electrical
insulation is not meet.
Where the markings on the visor and visor frame are different,
the lowest applies.
The eye protection according to EN 166:2001 is valid at
temperature -5 °C to +55 °C.
The head protection according to EN 397:2012 is valid at
temperature -30 °C to +55 °C.
If protection against high speed particles at extremes of tem-
perature is required, the letter T must be written immediately
after the impact letter, i.e. BT. If not, the eye-protector shall only
be used against high speed particles at room temperature.
Limitations
• The head-tops must not be used together with peel-offs in
potentially explosive atmosphere.
• 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 head top 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.
• The helmet is not designed to withstand penetrative impacts
from the front, sides or back, but can provide protection
against less severe impacts against those surfaces.
• Avoid contact with electrical wiring when using the helmet.
• When gluing items to the helmet, only rubber or acrylic-
based adhesives may be used. The helmet must not be
painted.
