Safety Cap 3M HC24NB/MP FB3 CLA Marine Blue EN 812 — protective hard hat, slip-on peak

The 3M HC24NB/MP FB3 CLA Safety Cap in Marine Blue is a lightweight protective hard hat designed to provide impact protection for the head in industrial and marine environments. Certified to EN 812, this cap features a low-profile shell and a slip-on peak for straightforward fitting and reduced snagging. The internal suspension is compatible with 3M fittings to ensure stable positioning and consistent protection during general maintenance, shipboard tasks and other applications where a compact, durable head protector is needed.

Advantages

The cap’s low-profile design reduces interference with other personal protective equipment and improves mobility in confined spaces. The slip-on peak allows quick donning and doffing without compromising coverage. Constructed from durable materials, the shell resists everyday wear typical of industrial and marine work. The internal suspension system provides shock absorption and an adjustable fit to accommodate different head sizes while maintaining effective impact protection.

Suitable for (tasks / use cases)

• Shipboard maintenance and deck operations
• General industrial and factory use
• Maintenance, inspection and light construction tasks
• Personnel requiring a low-profile hard hat for confined spaces

How to use

Select the correct suspension setting to match the wearer’s head size and place the cap on the head so the shell fully covers the crown and forehead area. Ensure the slip-on peak sits comfortably without obstructing vision. Adjust the internal suspension and any chin straps (if fitted) to achieve a secure, stable fit that prevents excessive movement during tasks. Periodically inspect the shell and suspension for cracks, deformation or wear, and replace components according to the manufacturer’s maintenance guidance or if damage is detected.

Usage recommendations

Use this safety cap in environments where EN 812-compliant head protection is required. Do not modify the shell or suspension, and avoid exposing the cap to chemicals or extreme heat that could degrade materials. Replace the cap after significant impact, visible damage or after the manufacturer’s recommended service life. Combine with other compatible PPE — such as ear and eye protection — as appropriate for the task and workplace risk assessment.
