1. General information
Use of a respirator must be part of a respiratory protec tion
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 Sundstrom Safety AB.

1.1 System description

Sundström welding shield SR 592 together with the fan
unit SR 500/SR 700 and approved filters are included in
the Sundstrom fan-assisted respiratory protective device
system conforming to EN 12941:1998 (Fig. 1). 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.
1.2 Applications
The equipment can be used as an alternative to filter respirators
in all situations in which these are recommended. This applies
particularly if the work is physically demanding, warm or of
long duration. The welding shield in combination with fan is
designed specifically for protection against harmful gases,
radiation and spatter during welding, flame-cutting, grinding
and similar work.
When selecting the head-top, some of the factors that should
be taken into account are as follows:
• Types of pollutants
• Concentrations
• Work intensity
• Protection requirements in addition to respiratory protective
device.
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.
Do not use the equipment in environments:
• that are Immediately Dangerous to Life and Health (IDLH).
• where the ambient air is oxygen-enriched air or does not
have a normal oxygen content.
• where the pollutants are unknown.
Do not use the equipment:
• 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.
• without the face seal of the head-top against the face

is assured. The face seal must firmly come in contact
with the face to form the pressure that is necessary
for establish the correct protection factor. This may be
difficult to achieve if the user has a beard or sideburns.
• if the welding filter is damaged. Change the welding filter
immediately if it is found to be damaged.
• without checking that the welding filter have the correct
scale number for your work.
• If the welding shield is equipped with a toughened mineral
glass lens, a protective lens (item 8 in 2.2 Accessories/
Spare parts) should be fitted on the inside of the tough-
ened mineral glass lens.
Where the markings on the visor and visor frame are different,
the lowest applies.
Stop the work immediately:
• if you find that breathing is difficult.
• if you experience dizziness, nausea, or any other noti-
ceable physical effect.
• if you smell or taste the pollutants.
Note that:
• the equipment not is approved for use in an explosive
atmosphere.
• the equipment, 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 equipment may reduce the protection factor if it is
used in surroundings in which high wind speeds occur.
• the equipment should never be lifted or carried in the
breathing hose.
• materials that come into contact with the user's skin may
give rise to allergic reactions if the user is sensitive.
• damaged or scratched protective lens must immediately
be replaced.
• the welding shield must always be fitted with a protective
lens in addition to the welding filter.
• the fire safety rules always must be observed.
Be aware that the breathing hose might make a loop and get
caught up by something in your surrounding.
