STANDARD EN 443

Good to READ

Main requirements of the EN 443 standard

Thermal protection

• Resistance to radiant and convective heat : Helmets must protect the wearer's head against the intense heat generated by fires.
• Thermal insulation : Helmets must maintain a bearable internal temperature, even with prolonged exposure to high temperatures.

Mechanical protection

• Impact resistance : Helmets must effectively absorb and distribute impact energy to protect the head from injury caused by falling objects or impacts.
• Puncture resistance : Helmets must be able to resist penetration by pointed or sharp objects.

Electrical protection

• Resistance to electric arcs : Helmets should provide some protection against electrical hazards, including arc flash and short circuits.

Design and comfort

• Adjustability : Helmets should be adjustable to properly fit the heads of different users, with adjustment systems that ensure a secure and comfortable fit.
• Weight : Helmets should be light enough not to cause excessive fatigue during prolonged use.
• Ventilation : Helmets may include ventilation systems to improve thermal comfort without compromising protection.

Visibility and identification

• Reflective strips : Helmets should be equipped with reflective or high visibility strips to improve firefighters' visibility in low light or dense smoke conditions.
• Individual identification : Helmets must allow the addition of markings or insignia for individual or unit identification.

Testing Methods

Test methods for helmets according to EN 443 include:

• Radiant and convective heat tests : Measure the ability of helmets to protect against intense heat.
• Shock resistance tests : Use controlled impacts to evaluate the ability of helmets to absorb and distribute energy.
• Puncture tests : Evaluate the resistance of helmets to penetration by sharp objects.
• Electrical resistance tests : Check the ability of helmets to protect against electric arcs and short circuits.
• Comfort and fit testing : Ensuring that helmets can be adjusted to provide optimal comfort and safety for different users.

Importance of the standard

• Firefighter Safety : The EN 443 standard ensures that protective helmets offer effective protection against the multiple dangers encountered during structural firefighting interventions.
• User trust : Firefighters can have confidence that their helmets have been rigorously tested and meet high safety standards.
• Regulatory conformity : The standard helps fire services comply with current safety regulations, ensuring their equipment is suitable for current protection requirements.
