MLA Defender Helmet

MLA Defender Public Order Helmet [Size Options: 00]

Description

The Defender Helmet is designed for use by Police, Prisons and other Public Security Personnel when engaged in controlling the actions of persons involved in actual or potential public order disturbances.

The Home Office Scientific Development Branch’s Protective Headwear Standard for UK Police 2004 21/04 requires that helmets should meet specific performance levels for:

Coverage (both Helmet and Visor)
Peripheral Vision
High and Low Velocity Impact
Penetration
Impacts to the Visor
Burning Solvent Test
Flammability
Ingress of Liquids
Acoustics
Helmet Retention
Weight
Visor deformation under impact
Pellet Impacts to the Visor (6mm ball)
Visor misting
Visor resistance to solvents

The Defender meets, or exceeds, all of these criteria and has been tested, accredited and certified to 21/04 by the HOSDB.

The Helmet is not designed to offer protection from ballistic attack.

The Helmet consists of an outer shell with hearing apertures and fittings, an inner liner with comfort padding, a hinged clear visor and adjustable chinstrap with cup.

The visor may be swung upwards over the outer shell and clear of the face. However, whenever possible it should be worn with the visor in place in front of the face with the chinstrap fastened and correctly adjusted (A rubber seal fitted between the visor bar and the outer shell to prevent liquid ingress to the face is only effective with the visor in the down position).

Manufacture is carried out in a BS EN 9001:2000 approved facility.
