An industrial safety helmet only protects if it fits and is actually worn. Fit, ventilation and weight decide whether a helmet is accepted all day long. This guide shows what to look for when choosing one, which colours and features our helmets offer and which accessories complement them. You will find all models in the safety helmets category.
What does EN 397 mean for a safety helmet?
EN 397 is the standard to which industrial safety helmets are certified. According to the product data, the helmets in our range carry this certification. For you, this means the helmet has been tested as an industrial safety helmet. Which hazards exist at your workplace, and whether a helmet to EN 397 is sufficient for them, follows from your risk assessment.
When buying, make sure the certification is stated on the helmet and in the manufacturer's documents. This article is a selection guide – the manufacturer's operating instructions apply for use and inspection.

Design: shell and interior
The helmets in the NITRAS HEAD PROTECT series consist of two parts: a shell made of HDPE and an interior made of LDPE and textile in black and grey. The specific protective performance of the helmet is defined by the EN 397 certification and the manufacturer's information. The interior deserves a close look in particular, because it determines how comfortable the helmet still feels after several hours. Before placing a larger order, let your staff try on and adjust the helmet if possible.
- Harness: a 6-point system holds the helmet on the head.
- Size: the padded neck band with a ratchet wheel allows step-by-step size adjustment.
- Comfort: a fleece sweatband on the forehead absorbs sweat, and ventilation slots on the sides and at the back of the head help regulate heat.
- Hold: an adjustable chin strap ensures a secure fit.
- Weight: approx. 370 g according to the manufacturer.
There is also a short peak and side Euroslot mounts of 30 mm. Which accessories are intended for these mounts can be found in the manufacturer's information.
The colours in our range
All three versions share the same equipment; they differ in the colour of the shell:
- Yellow: NITRAS HEAD PROTECT, industrial safety helmet, shell made of HDPE, yellow, interior made of LDPE / textile, black / grey, EN 397. The manufacturer highlights the bright colour for visibility.
- White: NITRAS HEAD PROTECT, industrial safety helmet, shell made of HDPE, white, interior made of LDPE / textile, black / grey, EN 397.
- Black: NITRAS HEAD PROTECT, industrial safety helmet, shell made of HDPE, black, interior made of LDPE / textile, black / grey, EN 397.
Many companies assign helmet colours internally to certain groups, such as visitors or individual departments. Such a rule is yours to define. What matters is that it is known throughout the site and applied consistently.
Accessories: chin strap and helmet insert
For the helmets in this series there are accessories that, according to the manufacturer, fit article 9500:
- Chin strap: the NITRAS chin strap, black / transparent is adjustable and has a clip. It is made of polyester and plastic.
- Helmet insert: the NITRAS helmet insert, black / grey has an adjustable circumference of 53-64 cm, a fleece sweatband of brushed nylon on foam, a 6-point harness and a padded neck band with a ratchet wheel.
A new helmet insert lets you renew the interior, for example when several people share a helmet or the sweatband is worn. Whether and when a replacement is needed is set out in the manufacturer's instructions.
Typical applications
Warehouse with high racking
Whether a helmet must be worn in your warehouse is determined by your risk assessment. Where it is used: a well-adjustable fit and ventilation help ensure it is worn during longer shifts too. A conspicuous shell colour such as yellow also makes staff easier to see.
Production and workshop
In production and workshops, too, the risk assessment determines where head protection is needed and what requirements it must meet. According to the manufacturer, the adjustable chin strap is there for an optimum fit.
