4.1 The EEBD should have at least a duration of
service of 10 min.
4.2 The EEBD should include a hood or full face
piece, as appropriate, to protect the eyes, nose and mouth during
escape. Hoods and face pieces should be constructed of flame resistant
materials, and include a clear window for viewing.
4.3 An unactivated EEBD should be capable of being
carried hands-free.
4.4 The EEBDs, when stored, should be suitably
protected from the environment.
4.5 Brief instructions or diagrams clearly illustrating
the use should be clearly printed on the EEBD. The donning procedures
should be quick and easy to follow for situations where there is little
time to seek safety from the hazardous atmosphere.
4.6 Unless personnel are individually carrying
EEBDs, consideration should be given for placing such devices along
the escape routes within the machinery spaces or at the foot of each
escape ladder within the space. In addition, control spaces and workshops
located within the machinery spaces should also be considered for
the possible location of such devices.
