permitting it to be cleaned easily. The headband can be removed from the
helmet for cleaning without tools. The entire helmet inner lining can be replaced
easily due to the simple screw attachments on 3 points on the interior shell of
the helmet.
The covering of the headband is also available in leather (optional). The novel
method of adjusting the headband to the relevant hat size from the outside
provides individual adjustment.
The wearing height of the helmet can be adjusted using two perforated sliders
on the left and right at the rear of the interior harness. The gap between the
nose and the visor is also adjusted at the same time. The wearing height of the
headband can be set in three positions.
In addition, a basic head size position can be established using the longitudinal
adjustment of the headband (two positions).
3.3 The visor on the HEROS-xtreme fire fighting helmet is made of high-
strength polycarbonate.
WARNING: In order to ensure that the protective function of the visors
conforms to standards, they must be swivelled out 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 100W/ m .

3.4 Chinstrap
The trapezoidal shaped chinstrap is made of flame-retardant, highly
heatresistant material. In combination with the integrated padding, the chin-
strap ensures pleasant wearing. The chinstrap can be individually adjusted both
laterally and vertically in the neck area.
NOTE: This helmet fulfils the requirements of EN443:2008 for the strap
system if the chinstrap supplied by the manufacturer is worn and
adjusted according to these regulations.
3.5 Neck protection
The helmet is fitted with a neck guard. All the materials employed are flame
retardant and highly heat-resistant. The neck guards are secured to the interior
helmet harness and the helmet shell by a tension strip and are easily removed
for cleaning purposes. The neck guard offers generous cover for the neck and
ear areas without reduction of the hearing.
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 guard is a protective device, made of soft, flexible
material, which offers limited mechanical protection. Neck guards are
wear parts and should be stocked in sufficient quantities. In operations
in which a flashover or a similar event is to be expected, we strongly
recommend that all-round neck protection and a flame protection hood
be used.
4. Instructions for use
4.1 Helmet size adjustment:
A basic helmet setting can be established as a result of the unique possibility
provided for adjusting the headband to the respective head size from the outside.
The setting screw on the outside of the
helmet can be used to adjust the size from
52 to 65; if the hat size is smaller, the basic
width of the headband can also be adjusted
(see 4.1.3). Open the helmet harness, put
the helmet on and tighten the harness until
the helmet sits firmly, without a feeling of
excessive pressure.
