1. General
The SEA full face mask is a panorama full view mask. It is designed to protect the respiratory system
and face against hazardous gases and particles and to maintain a wide field of vision. The mask is
used as a filtering device together with gas, particle or combined filters (threaded filters) as well as
with portable and hose-fitted constructions. The mask has a speech diaphragm made of plastic film
with minimal sound absorption. The SEA full face mask conforms to EN 136 in Europe and AS1716 in
Australia.
Respiratory filters may be of one of two types:
• Threaded filters conforming to EN 148-1.
• Clip-in filters, to be fitted to the filter adaptor supplied with the mask, which is then screwed into the
mask.
2. Limitations of use
2.1 The filtering device must not be used if the environment and contamination are unknown. In
case of doubt,self-containedrespirators which function independently of the atmosphere must
be used.
2.2 The filtering device must not be used in restricted spaces (e.g. cisterns, tunnels) because of
oxygen deficiency or presence of heavy oxygen-displacing gases (e.g. carbon dioxide).
2.3 The filtering device may be used only if the oxygen content of the air is 18 - 23 vol.% (minimum
USA 19,5%). An oxygen analysis instrument is recommended for measuring the oxygen content.
2.4 Gas filters do not protect against particles. Similarly, particle filters do not provide protection
against gases or vapours. In case of doubt, use combined filters.
2.5 Normal filtering devices do not protect against certain gases such as CO (carbon monoxide),
CO
2
(carbon dioxide) and N
2
(nitrogen).
2.6 SEA recommends that filters be changed aftersingle use if they have been used against
radioactive agents, micro-organisms (virus, bacteria, fungi and spores) or enzymes.
2.7 It is likely that adequate protection cannot be guaranteed if the sealing edge of the mask is
obstructed by the user’s beard, hair or spectacle frames. With the SEA full face mask one can
use special spectacles (see spare part FSF-T).
2.8 When a breathing protector is used in explosive atmospheres, please follow the instructions
given for such areas.
2.9 The weight of filter used with a full face mask shall not exceed 500 g.
2.10 Gas filters shall be replaced when the user begins to sense odour, taste or irritation. Filters used
against detrimental gases that do not display any significant indications, require special
regulations for the duration of use and correct usage.
