seen in the diagram, 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/m2.
ATTENTION: The visor features anti-fog coating on the inside. The visor and the coating
must be meticulously cared for at regular intervals with warm water, a soft cloth and, if
necessary, mild dishwashing liquid. Visors should never be cleaned when dry or using
aggressive or abrasive materials. Even with proper care, this coating has a limited
resistance with corresponding use. Detachment of the inner display coating does not
represent a defect; in this case it is recommended you replace the visor.
3.4 Chin strap
The trapezoidal chin strap is made from flame-retardant, highly heat resistant
material. The width and the height of the chin strap can be adjusted individually
around the neck by means of Velcro strips.
NOTE: This helmet fulfills the requirements of EN 443:2008 for the strap system if the chin
strap supplied by the manufacturer is worn and adjusted according to these regulations.
3.5 Neck protector
The helmet can be equipped with a neck protector as an option. All the materials
are flame retardant and highly heat resistant. The neck protectors are attached
with a clamping strip to the helmet liner or to the helmet shell and can be easily
removed for cleaning. The neck protector amply covers the neck and ears while
still allowing for problem-free communication. Neck protectors are wear parts; a
sufficient number should be kept in stock. The "Holland" all-round neck protection
is optionally available in place of the standard neck protection.
WARNING: The neck protection is a protective guard, which is made of a soft flexible
material. These materials have a limited ruggedness and can only provide limited
protection. In operations in which a flashover or a similar event is to be expected, we
strongly recommend to use a flame protection hood together with the standard neck
protection or the all-round neck protection.
