Area Adjustment Procedure
Faceshield
(external)
WARNING!
To maintain NFPA compliance, use ONLY MSA approved eye protection such as a Defender visor,
faceshield, or goggles. Removing compliant eye protection voids the NFPA certification.
MSA recommends wearing approved eye protection, such as safety glasses that comply with ANSI/
ISEA Z87.1 and CSA Z94.3 (current editions), in conjunction with the faceshield.
Failure to follow this warning can result in serious personal injury or death.
The faceshield material has been selected for its resistance to impact and penetration, as well as for
premium optical clarity.
1. Remove the protective cover from the lens.
2. To raise or lower the faceshield, loosen the knobs on both sides of the faceshield brackets.
3. Adjust the faceshield.
4. Tighten the knobs on both sides of the faceshield brackets.
Defender Visor
(internal)
WARNING!
A Defender visor that is not stowed securely may interfere with the SCBA facepiece seal.
Do not wear eye glasses under the Defender visor. Safety glasses that comply with ANSI/ISEA
Z87.1 and CSA Z94.3 (current editions) may be worn under the Defender visor as long as there is
no interference. If interference is anticipated, purchase a fire helmet with an MSA faceshield
instead.
Failure to follow this warning can result in serious personal injury or death.
The Defender visor stays locked inside the fire helmet until eye protection is necessary.
• To lower the Defender visor, grasp the handles on either side of the lens, then pull down and
back.
• To raise the Defender visor, grasp the handles on either side of the lens, then push up until
the visor locks into position.
• To articulate the lens, grasp the handles on either side of the lens and move the lens away or
toward your face.

Traditional Bourke lenses are for cosmetic purposes only and do not provide eye or face protection.

well as the certifying body mark.

ISEA Z87.1 and CSA Z94.3 (current editions), in conjunction with the NFPA Bourke lenses.
Failure to follow this warning can result in serious personal injury or death.
