1. Introduction
Use of a respirator must be part of a respiratory protec-
tion program. For advice see EN 529:2005 or AS/NZS
1715:2009. The guidance contained in these standards
highlights important aspects of a respiratory protective device
program but does not replace national or local regulations.
Sundström welding shields 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/EN 12942:1998 and the Powered Air
Purifying Respirator (PAPR) system conforming to AS/NZS
1716:2012 (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.
The welding shields in combination with fan is designed specifi-
cally for protection against harmful gases, radiation and spatter
during welding, flame-cutting, grinding and similar work.
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 Applications
The equipments 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. 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.

1.2 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:
• 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 toughened 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 noticeable
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, a partial vacuum 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.
