During use
4.4
After use
Check usability as follows:
Check helmet shell, internal helmet components, chin strap
and accessories. Replace defective parts.
Check visor. In case of visible damage, or impaired vision
(e.g. by scratches, discolouring), the visor should be
replaced.
Check the paint coating of the fire helmet for damage.
The special self-extinguishing coating is the most important
factor for the thermal performance of the helmet. Damaged
coating might shorten the usage period. Small surface
scratches or damages to the paint work do not reduce the
protective effect. They can be repaired with repair paint.
Fire helmets that are out of use, or cannot be repaired any
more must be destroyed for safety reasons.
Trained personnel or Dräger can check and decide if a
damaged fire helmet is still suitable for use or can be repaired.

Maintenance intervals
Replace the rubber grommets on the screws and the O-rings
on the locating pieces every 6 years (see the technical
manual).
5.2
Cleaning and disinfecting
1. Remove attached components (e.g. visor, neck protection,
lamp) from fire helmet and clean separately.
2. Prepare a cleaning solution of water and detergent.
3. Clean the helmet shell using a soft cloth and the cleaning
solution.
4. Rinse helmet shell and visor with clear water and wipe dry.
5. Apply the anti-fog solution kp-Comfort to the visor.
When the internal helmet components must be disinfected:
1. Prepare a disinfection bath of water and a disinfectant.
2. Place all parts to be disinfected into the disinfectant bath
(duration: 15 minutes).
3. Rinse all parts thoroughly under running water.
4. Dry all parts in the air or in a drying cabinet (temperature:
max. 60 °C). Do not expose to direct sunlight.
NOTICE
The helmet does not contain any materials that are
known to cause allergic reactions. However, in isolated
cases this might be the case anyway.
The visor might transfer impacts to spectacles and
damage the spectacles.
Full protection is only achieved when the face
protector is locked into the lowest position.
CAUTION
The protective effect is reduced after impact!
If the fire helmet absorbs the energy of an impact, it
can get damaged or destroyed.
Even if the damage is not visible at first, the fire helmet
must be replaced after a heavy bump or impact.
Do not use damaged or impact-stressed fire helmets.
This also applies if no external damage is visible.

agents or processes, dosages and contact times may
damage the product.

disinfectants and their specifications, see document
