Ships carrying mixtures the benzene content of which is
0.5% or more should carry safety equipment equivalent to what is required
in paragraph 14.2 of the IBC Code.
.2 Equipment for cargo operations on deck
Whenever direct or representative measurements indicate
that the exposure limits are exceeded during normal cargo handling
operationsfootnote, crew required to work
in the affected area should wear appropriate respiratory equipment
to be used in accordance with the manufacturers instructions. Such
equipment is indicated belowfootnote, however
the crewmember may select a higher level of protection:
-
.1
Half face piece: in areas where
the airborne concentration of benzene vapours is expected to exceed
1 ppm but not more than 10 ppm;
-
.2
Full face (filter) piece with cartridge: in
areas where the airborne concentration of benzene vapours is expected
to exceed 10 ppm but not more than 50 ppm;
-
.3
Air supplied respirators: in areas
where the airborne concentration of benzene vapours is expected to
exceed 50 ppm, but not more than 100 ppm;
-
.4
Pressure demand breathing apparatus and
full protective clothing, resistant to chemical attackfootnote:
in areas where the airborne concentration
of benzene is expected to be greater than 100 ppm; and
-
.5
Personal protective equipment: eye
protection, impervious gloves and a protective apron should be readily
available to crew members while sampling and gauging or when skin
contact with the cargo is likely.
