An unvented ABS industrial safety helmet with an integrated anti-fog goggle, rated to EN 397:2012+A1:2012 and carrying dual eye protection certification for construction, civil engineering, and industrial environments.
An unvented ABS industrial safety helmet with an integrated anti-fog goggle, rated to EN 397:2012+A1:2012 and carrying dual eye protection certification for construction, civil engineering, and industrial environments.
An unvented ABS industrial safety helmet with an integrated anti-scratch and anti-fog goggle, built for construction sites, civil engineering projects, and industrial environments where head and eye protection must be worn simultaneously. The Denali carries certification to EN 397:2012+A1:2012 for head protection, with the integrated goggle independently certified to EN 166:2001 and EN 14458:2004, providing a single compliant system in place of separate head and eye PPE. Available in white, black, and blue, and compatible with CMT's BrandIT in-house logo printing service.
The standard practice of issuing a safety helmet and separate safety spectacles or goggles creates a well-documented compliance problem: workers remove the eye protection when it becomes uncomfortable or inconvenient, and supervisors cannot enforce compliance across a shift without direct observation. The result is intermittent eye protection, not continuous protection. The Denali addresses this by housing the goggle within the helmet brim, where it is immediately available without a separate donning step and stows cleanly out of the line of sight when the task does not require it. Workers are more likely to use eye protection that requires no extra effort to access, and compliance becomes easier to maintain and to evidence.
Integrated anti-scratch and anti-fog goggle: Polycarbonate goggle rated to EN 166:2001 and EN 14458:2004 stows inside the helmet brim and deploys in a single motion. Full EN 166 marking: 3-1.2 1 B 8 9 K N, optical class 1, medium energy impact resistance, short circuit electric arc resistance, molten metal and hot solids resistance, anti-scratch, and anti-fog coatings. Goggle tested to -20°C.
Unvented ABS shell: Acrylonitrile Butadiene Styrene shell in a fully enclosed, unventilated construction. Provides strong impact and heat resistance with no apertures in the shell surface.
EN 397:2012+A1:2012 and EN 50365:2002 certified: Meets the UK industrial safety helmet standard including optional low-temperature classification to -30°C, lateral deformation resistance, and molten metal splash resistance (MM). EN 50365:2002 confirms electrical insulation for short-term accidental contact with live conductors up to 440V AC.
6-point suspension harness with integrated adjustment: Six-point harness distributes load across the head for comfort across extended shifts. Integrated ratchet adjustment covers head circumferences from 52 to 63 cm without separate insert pads.
Side euro slot adapters: Standard euro slot mounting points on both sides of the shell accept compatible helmet-mounted hearing protection, enabling a combined head, eye, and hearing protection configuration.
BrandIT compatible: Available with in-house logo printing via CMT's BrandIT service, suitable for principal contractor programmes and branded PPE requirements.

These helmets are used primarily by site managers, supervisors, and construction operatives working on UK construction and civil engineering sites where simultaneous head and eye protection is required by a site PPE rule or task-specific risk assessment. They are equally suited to industrial and utilities environments where falling object risk is present alongside dust, debris, or splash hazards. Safety officers and procurement managers specifying PPE for multi-trade packages or principal contractor programmes will find the dual-standard compliance and BrandIT branding capability relevant to their requirements.
Working beneath active overhead operations on construction sites where both falling object risk and airborne debris require simultaneous head and eye protection.
Civil engineering groundwork and drainage installation in dusty or debris-generating environments where separate safety spectacles are regularly lost, damaged, or removed.
Highways and infrastructure maintenance involving saw-cutting, breaking, or excavation work where grit and chip hazards accompany general overhead risk.
Industrial production and manufacturing environments where operatives move between zones with differing PPE requirements and need rapidly deployable eye protection without changing headgear.
Utilities and infrastructure inspection work in confined or partially confined environments where both overhead impact and dust or splash exposure are present.
Principal contractor programmes requiring branded helmets across multiple trade packages, where consistent PPE specification simplifies site inductions and compliance checking.
Cold weather outdoor construction work where low temperature classification to -30°C is required under the site PPE specification.
Step 1: Check the shell and harness for cracks, deformation, or damage before every shift. Do not use a helmet that has sustained an impact, even if no visible damage is present, the ABS shell absorbs impact energy and its structural integrity cannot be confirmed by visual inspection alone after a strike.
Step 2: Fit the helmet by placing it squarely on the head with the peak facing forward. Operate the ratchet adjustment system at the rear to tighten the harness until the helmet seats firmly without rocking. The 6-point harness should contact the head evenly without pressure points.
Step 3: Where the optional chinstrap is fitted, connect and adjust it so that it seats below the chin without restricting jaw movement. The chinstrap must not be overtightened.
Step 4: Where the integrated goggle is fitted, slide it down from its stowed position inside the brim before entering the hazard zone. Check the polycarbonate lens for scratches or damage before deploying. A damaged lens must be replaced before use.
Step 5: Confirm the goggle seats correctly across the face with no gaps at the sides before beginning work. Return it to the stowed position inside the brim when moving clear of the eye hazard.
Step 6: At the end of each shift, wipe the shell and goggle lens with a damp cloth. Store in a cool, dry location away from direct sunlight, solvents, and heat sources.
Continuing to use a helmet after a significant impact: ABS absorbs energy during impact and may be compromised without visible surface cracking. Any helmet that has sustained a significant blow must be replaced immediately, regardless of appearance.
Wearing the helmet pushed back off the forehead: the shell peak must face forward for the suspension system to function correctly. A helmet worn incorrectly provides reduced protection and may not meet the requirements of the EN 397 standard during an impact.
Cleaning the goggle lens with abrasive materials or solvent-based cleaners: both damage the anti-fog and anti-scratch coatings, reducing optical clarity and shortening the service life of the goggle. Use a damp soft cloth only.
Removing the goggle because it fogs: fogging on a used or scratched goggle lens indicates coating wear. The lens should be inspected and replaced rather than the goggle abandoned.
Attaching non-compatible accessories to the euro slot adapters: only accessories confirmed as compatible with the euro slot system should be fitted. Non-compatible fittings may compromise the helmet's certified performance.
These helmets are certified to EN 397:2012+A1:2012 for industrial head protection, including optional low-temperature classification to -30°C and lateral deformation resistance. The integrated goggle, where fitted, is certified to EN 166:2001 and EN 14458:2004. This helmet is not certified to EN 12492 and is not suitable for working at height applications where that standard is required. No electrical insulation rating under EN 50365 is confirmed for this product, do not use in environments where an electrically insulating helmet is required unless EN 50365 certification has been independently verified. Safety helmets have a finite service life: follow the manufacturer's stated replacement interval and replace immediately after any significant impact or if the shell shows any sign of cracking, discolouration from UV exposure, or deformation.
Wipe the shell and goggle lens after each shift with a damp cloth and mild detergent. Do not use solvents, thinners, or abrasive materials on any part of the helmet. Inspect the harness webbing for wear, fraying, or deformation at each inspection. Replace the sweatband when it shows signs of saturation or deterioration. Inspect the goggle lens for scratching, crazing, or coating damage, a degraded lens reduces optical protection and must be replaced before further use. Store the helmet in a cool, dry location, away from direct sunlight and heat sources. Do not store under heavy loads or in positions that deform the shell.
Q: What does EN 397:2012+A1:2012 mean for this helmet, and what protection does it provide?
A: EN 397:2012+A1:2012 is the UK and European standard for industrial safety helmets. It requires the helmet to absorb the force of a 5kg striker dropped from one metre to below 5kN, and to resist penetration from a 3kg pointed object dropped from the same height. It also requires resistance to flame for at least five seconds. This helmet meets four optional additional requirements within EN 397: low-temperature classification to -30°C, resistance to lateral deformation, molten metal splash resistance (MM), and electrical insulation under EN 50365:2002 for short-term accidental contact with live conductors up to 440V AC.
Q: What is the integrated goggle certified to, and what does the full marking mean?
A: The goggle carries dual certification to EN 166:2001 and EN 14458:2004, with a full lens marking of 3-1.2 1 B 8 9 K N. Each element of that marking is a confirmed test result: 3-1.2 identifies this as a helmet-mounted face guard at optical class 1, the highest level of optical clarity. B confirms medium energy impact resistance, tested to a 43g steel ball at 120m/s. 8 confirms resistance to short circuit electric arc. 9 confirms resistance to molten metals and penetration of hot solids. K confirms anti-scratch coating, providing resistance to surface damage from fine particles. N confirms anti-fog coating. The goggle has also been tested to -20°C. This is a significantly more capable level of eye protection than standard safety spectacles and covers most hazards present on UK construction and industrial sites.
Q: What is this helmet NOT suitable for?
A: This helmet is not certified to EN 12492 and must not be used for working at height applications where that standard is required, such as rope access, scaffolding, or arboriculture. The integrated goggle provides broad eye and face coverage but is not a substitute for a full-coverage face shield in chemical immersion or chemical splash environments where an EN 374-rated full face shield is required. Whilst the helmet shell carries EN 50365 electrical insulation up to 440V AC, this covers short-term accidental contact only — it is not a substitute for fully rated electrical PPE systems where deliberate live working is involved.
Q: Why use a helmet with an integrated goggle rather than a separate helmet and safety spectacles?
A: Separate safety spectacles are among the most frequently removed or lost items of PPE on UK construction sites. Workers remove them when they mist, scratch, sit awkwardly with the helmet harness, or become an inconvenience between tasks. An integrated goggle removes that compliance gap by housing the eye protection within the helmet itself, where it is immediately accessible without a separate donning step and stows cleanly when not needed. With a goggle rated to B, 8, 9, K, and N under EN 166, it also provides a higher level of protection than most standalone spectacles issued as standard PPE.
Q: Can I attach ear defenders directly to this helmet?
A: Yes. The Denali carries standard euro slot adapters on both sides of the shell, which accept compatible helmet-mounted ear defenders. This enables a combined head, eye, and hearing protection configuration without a separate head harness for the ear defenders. Confirm compatibility with your ear defender manufacturer before fitting, only accessories confirmed as compatible with the euro slot system should be attached.
Q: Is this helmet suitable for use near live electrical installations?
A: The unvented ABS shell carries EN 50365:2002 certification, confirming electrical insulation for short-term accidental contact with live conductors up to 440V AC. This makes the helmet appropriate for environments where incidental contact with low-voltage installations is a foreseeable risk. It is not rated for deliberate live working and is not a substitute for a full electrical PPE system where intended contact with live conductors is involved. For arc-rated and higher-voltage environments, the armourU Fuji Safety Helmet carries additional arc protection and electrical insulation certification.
Q: How long should this helmet last before it needs replacing?
A: ABS safety helmets are typically replaced every three to five years from the date of first use, following manufacturer guidance and your site PPE policy. UV exposure, temperature cycling, chemical contact, and physical wear all degrade the ABS shell. The helmet must be replaced immediately after any significant impact regardless of whether visible damage is present, the shell's energy absorption capacity cannot be confirmed by visual inspection after a strike. The goggle lens should be inspected separately and replaced when anti-fog or anti-scratch coating degradation affects optical clarity.
Q: Is this helmet available with a company logo?
A: Yes. CMT Group's BrandIT service provides in-house logo printing on armourU helmets, including the Denali. Printing is carried out in-house for fast turnaround, making it suitable for principal contractor programmes, site-specific PPE requirements, and procurement teams managing branded PPE across multiple trade packages.
