1. General information
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.
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 Sund-
ström Safety AB.
1.1 System description

1.2 Applications
The SR 500 can be used as an alternative to filter respi-
rators in all situations for which these are recommended.
This applies particularly to work that is hard, warm or of
long-duration.
When selecting filters and head top, the following are
some of the factors that must be taken into account:
• Possible occurrence of explosive atmosphere
• Types of pollutants
• Concentrations
• Work intensity
• Protection requirements in addition to respiratory
The risk analysis should be carried by a person who has
suitable training and experience in the area.
