personnel who rely on it for their safety can sustain serious personal injury or death.
This helmet does NOT provide protection from all burns, injuries, diseases, conditions, or hazards. Do not perform
Technical rescue activities without the proper training and equipment.

designated. Avoid exposure to flashovers, collapses, falls, and other conditions that may exceed the protective capacity
of the technical rescue helmet.
If this technical rescue helmet is exposed to heat, you may be BURNED with NO warning and NO sign of damage to the
technical rescue helmet.
The optional ANSI Z87 visor/face shields provide LIMITED protection to the area they cover. The visor provides
LIMITED protection to the area covered.
To provide maximum protection and reduce the risk of injury, adjust the helmet with all components in position to fit on
the head properly and fasten the chinstrap securely.
Do not use the helmet as a vehicular or sports helmet.
Follow the procedures in Section 5.2.1 Routine Inspection to inspect the helmet after EACH use. Replace any part of
the helmet that shows signs of wear or damage.
All plastics can degrade over time. Inspect routinely and replace damaged plastic components immediately.

3 Use and Adjustment
For adequate protection, this helmet must fit or be adjusted to the size of the user’s head.
The attention of users is also drawn to the danger of modifying or removing any of the original component parts of the
helmet, other than as recommended by the helmet manufacturer. Helmets should not be adapted for the purpose of
fitting attachments in any way not recommended by the helmet manufacturer.
3.1 Basic Adjustments
Basic adjustments should enable a high level of comfort for most users. They can be performed with the helmet on the
head.
WARNING!
To provide maximum protection, make sure to adjust the helmet properly. Tightening the ratchet beyond its limits can
cause damage to internal gears and result in reduced protection.
Do not store equipment that is not explicitly authorized by MSA in or on the helmet. The storage of gloves, wedges,
lights, and other equipment in or on the helmet can dramatically change the protective capacity of the helmet.
Failure to follow this warning can result in serious personal injury or death.
Helmet Donning
(1) Position the chinstrap as shown.
(2) Grab the helmet with both hands and install it on your head.
(3) If too tight, open the headband by adjusting the knob (anticlockwise).
Head Size Adjustment
(1) Adjust the head size using the knob (clockwise to tighten, anticlockwise to
loosen) until you reach a snug fit on the head.
(2) Check tightness: helmet should not fall when leaning forward (with open
chinstrap).
Chinstrap and Retention System Adjustment
WARNING!
Never wear the helmet without fastening and tightening the chinstrap.
Failure to follow this warning can result in serious personal injury or death.
The retention system includes 5 adjustment points (chin, sides and rear) to secure retention on the head through a tight
fit of the chinstrap and rear straps.
6
US 3 Use and Adjustment

(1) Close the chinstrap buckle (if not possible, loosen the adjustment).
(2) Tighten the side and rear adjustments to achieve a tight, yet
comfortable fit (ear should be comfortable).
(3) Complete the adjustment with the chinstrap adjustment.
3.2 Advanced Adjustments
The following adjustments can be used to optimize wearing and comfort of the helmet after an initial assessment. They
should be performed if the basic adjustments do not enable a comfortable fit and must be performed without wearing the
helmet. Basic adjustments may need slight changes after advanced adjustments are completed.
3.2.1 Ride Height Adjustment
The suspension position in the helmet shell can be adjusted to modify ride height (3 positions), depending on wearer’s
head size and shape.
(1) Unlock the 3 yellow tabs (left, right, rear) by pulling them forward and down
(2) Adjust the suspension depth (left, right, rear) to the most comfortable ride
height. Ensure all tabs are positioned at the same depth.
– A : for smaller head size
– C : for larger head size
(3) Lock the yellow tabs by pulling them forward and up.
3.2.2 Nape Strap Height Adjustment
Nape strap height may be adjusted to optimize tightness and rear comfort (3 positions).
7

(loss of elastic tension).
4.2 Eye and Face Protection Visors
Face shields will provide protection to the eyes and substantial areas of the face.
WARNING!
Important Information on Visors (Ocular Visor and Face Shields):
• Users should ensure the correct type of visor is fitted to their helmet for their intended activity.
• The stated levels of protection are only provided when the visor is fully in the in-use protective position.
• Ocular visors will offer little or no protection to substantial areas of the face. They must only be used where an
adequate risk assessment indicates that facial protection is not required.

US 4 Accessories

• Mesh face shields are not suitable for wildland firefighting and only suitable for non-firefighting associated activities
such as wood cutting, road clearance, etc. Additionally, they should not be used where there is a risk of exposure to
heat, flame, sparks, splashes of harmful or molten liquids, or electricity.
• Visors meeting the requirements for electrical properties according to EN 14458 provide limited protection (brief
accidental unintended contact with live low voltage conductors), and all component parts of a visor/helmet assembly
shall have the same marking to achieve this.
• Visors worn over non-designated corrective frames may transmit impacts which may damage the corrective eyewear
thus creating a hazard to the user.
• Keep the ocular visor in standby position (stowed under the helmet shell) during the use of a breathing apparatus
(SCBA).
• Service life of visors depends on the conditions of use.
• Any visor or face shield that has been dropped or damaged must be replaced.
• Visors shall be regularly inspected. Any visor with a scratched or damaged lens must be replaced.
• Materials that come in contact with the wearer's skin could cause allergic reactions in susceptible individuals.
Failure to follow these warnings can result in serious personal injury or death.
4.2.1 Ocular Visor (GA3702)
Installation
(1) Insert the plastic clips in the shell slots until they click
in position.
Removal
(1) Push the plastic clips and slide them out of the
attachment slots.
WARNING!
With the ocular visor in the working position and adjusted, if there are gaps between your face and the spectacles that
could let external agents intrude and cause damage to your eyes, use safety glasses under the spectacles. Safety
glasses MUST comply with the applicable requirements of the latest revision of ANSI/ISEA Z87.1.
Failure to follow this warning can result in serious personal injury or death.
Use
(1) Position the ocular visor in-use by pulling it down.
