4.3.13 - Low smoke-emitting cables
Normal p.v.c.
insulation emits dense smoke and corrosive gases when burning.
If cables are to be run in areas of public access, such
as schools, supermarkets, hospitals, etc, the designer should
consider the use of special cables such as those with thermo-setting
or elastomeric insulation which do not cause such problems
in the event of fire. This action is most likely to be necessary
in areas expected to be crowded, along fire escape routes,
and where equipment is likely to suffer damage due to corrosive
fumes.
