General information

Use of a respirator must be part of the respiratory protection 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.
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
SR 580 together with the fan unit SR 500/SR 500 EX and approved filters are included in the Sundstrom fan-assisted respiratory protective device system conforming to EN 12941:1998 and the Powered Air Purifying Respirator (PAPR) system conforming to AS/NZS 1716:2012. (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 or SR 507 compressed air attachment can be used as an alternative to filtering 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 into account are as follows:

• Type of pollutants
• Concentrations
• Work intensity
• Protection requirements in addition to the respiratory protective device.

The helmet/visor must only be used when carrying out the 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.
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 a 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 another discomfort.

Materials that come into contact with the skin of sensitive people may cause allergic reactions. Damaged or scratched oculars must immediately be replaced. Eye-protectors against high-speed particles worn over standard ophthalmic spectacles may transmit impacts, thus creating a hazard to the wearer.

Where the markings on the visor and visor frame are different, the lowest applies.
The eye protection according to EN  166:2001 and AS/NZS 1337.1:2010 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.
The head protection according to AS/NZS 1801:1997 is valid at temperature -10 °C to +50 °C.
If protection against high-speed particles at extremes of temperature 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 a 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 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.
• 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.

  Breathing hose
  One end of the hose has a ø42 mm thread (fig. 1b/2b), whilst the other is fitted with an O-ring (fig. 1c/2c). The threaded end is to be connected to the helmet.
  3.2 Donning
  Also, see the user instructions for the SR 500/SR 500 EX fan and the SR 507 compressed air attachment, whichever is used.
• Check that the 6-point harness is secured correctly (fig. 9).
• Raise the visor and put on the helmet (fig. 10).
• If necessary, adjust the width of the helmet using the knob located at the rear of the harness (fig. 11).
• To adjust the height of the helmet interior, move the pins between positions a and b (fig. 12). If the interior is attached to pin a, the helmet will sit lower, and on pin b the helmet will be higher. To achieve the best fit, this adjustment can be made at both the front and back of the helmet.
• Lower the visor by pulling the face seal down below your chin. A ‘click’ indicates that the visor is fully lowered (fig. 13).
• Insert a finger inside the face seal and move it along the length of the contact surface to check the fit (fig. 14).
• Make sure that the breathing hose runs down your back and is not twisted. You can adjust the angle of the helmet connection as required (fig. 15).
