outside provides individual adjustment. The height the helmet is worn on the head
can be varied by 2 ratchet adjusters located on the left and right upper side of the
helmet liner. In addition, a basic head size position can be established using the
longitudinal adjustment of the headband (three positions).
3.3 Visor
The visor on the HEROS-titan fire fighting helmet is made of highstrength
polycarbonate.
WARNING: In order to ensure that the protective function of the visors conform to the
standards, they must be deployed completely. The visors have been developed and
inspected according to the applicable EN14458 standard; however, they do not provide
a guarantee that injuries are excluded. In extreme temperatures even the best helmet
visor materials lose their stability. Deformed, scratched or otherwise damaged
visors must be replaced immediately. Visors are wear parts and should be stocked
in sufficient quantities. The visors are located inside the helmet and can be swivelled
outwards. The protection against radiant heat provided by the visors depends on the
temperature of the heat source. The visors should be used only in situations in which
they can reduce the exposure of the wearer's eyes to less than 100 W/ m
