In the United Kingdom, industrial safety helmets must adhere to the EN 397 standard, which defines the minimum performance requirements for head protection in environments where there is a risk of falling objects and mechanical impacts.

To achieve compliance, hard hats undergo a series of rigorous tests designed to evaluate their durability and protective capabilities. These include assessments for impact resistance, penetration by sharp objects, and flammability. The aim is to ensure the helmet can effectively withstand a wide range of workplace hazards.

Designed for use in high-risk environments, these helmets exceed the standard requirements of EN 397 by offering enhanced protection. They are specifically engineered to guard against lateral impacts and deliver superior shock absorption. As a result, they tend to be larger and heavier than standard industrial helmets.

Key Requirements:

• Crown (top) shock absorption testing is carried out with a 100J impact.
• Side, front and rear shock absorption is assessed with a 50J impact, up to 60° from the crown.
• Crown penetration resistance is tested with a 1kg blade striker dropped from 2.5m
• Side, front and rear penetration resistance testing uses the same 1kg blade striker dropped from 2m.

EN 12492 specifies the safety requirements and test methods for helmets used in mountaineering, climbing, and work at height. These helmets provide protection against falling objects and impacts resulting from a fall.

Key Requirements:

• Impact protection (vertical and side impacts)
• Retention system effectiveness
• Ventilation
• Chin strap strength greater than 50 N to prevent detachment
• Suitable for work at height and rescue operations
