ATEX Certified Hearing Aids

Safeguarding the hearing health of workers in hazardous environments

ATEX-certified hearing aids for explosive atmospheres

If you work in an environment where flammable gases, vapours, or combustible dusts are present - or if you're an employer responsible for workers in these conditions - you'll know that standard hearing aids simply aren't permitted.

ATEX-certified hearing aids are the only legally compliant solution that allows workers with hearing loss to perform their roles safely whilst meeting UK Health and Safety Executive (HSE) requirements.

What are ATEX hearing aids?

ATEX-certified hearing aids are specialised devices designed to meet stringent safety standards for wearing in potentially explosive atmospheres.  For example, where flammable gases, vapours, or combustible dusts may be present.  These environments could be industrial settings such as oil rigs, chemical plants, or mining locations.

The actual word, ATEX, comes from the French term "Atmosphères Explosibles", which outlines regulations for equipment intended for use in potentially dangerous working environments. 

It doesn't stop at hearing aids either; other devices, such as mobiles, watches, and computers, have to be ATEX-certified to be used in these working conditions.  For example, when looking at both Rexton Reach and BiCore hearing aid ranges,

"The ATEX group/class is printed on the ATEX card, which must be available at hand when the hearing aids are used in explosive atmospheres. Ask your hearing care professional for your ATEX card"

Who needs ATEX hearing aids in the UK?

ATEX-certified hearing aids are essential for workers with hearing loss in industries including:

• Oil and gas extraction and refining - Both onshore and offshore platforms
• Chemical manufacturing and processing plants
• Pharmaceutical production facilities
• Mining operations - Particularly coal and mineral extraction
• Paint and solvent manufacturing
• Petrochemical facilities
• Grain handling and storage (flour mills, feed mills)
• Wastewater treatment plants
• Any environment classified as ATEX Zone 0, 1, 2, 20, 21, or 22

If you're unsure whether your workplace requires ATEX certification, your health and safety officer or facility manager will be able to confirm. Many companies conduct ATEX assessments that identify which zones require certified equipment.

ATEX certification testing and long-term durability

Before an ATEX hearing aid reaches you, it goes through extensive testing — checking how it performs under heat, pressure, and impact, and verifying that it simply cannot generate enough energy to cause ignition in a hazardous atmosphere.

This means that they are often made from robust housing materials that can withstand harsh conditions, offer protection from moisture and corrosion, whilst minimising the risk of leaks or electrical sparks.

ATEX Certification Hearing Aids

In addition to meeting safety requirements, what else can intrinsically safe hearing aids support you with?

Why standard hearing aids create explosion risks

Standard hearing aids contain electronic components that can generate tiny sparks or heat during normal operation - completely safe in everyday environments but potentially catastrophic in atmospheres containing flammable substances. Even a microscopic spark from a battery connection or circuit board could ignite gases or dust particles, causing an explosion.

ATEX-certified hearing aids are built differently from the ground up — designed so that even in a fault condition, they cannot release enough energy to cause ignition. This means they're constructed in ways that make it physically impossible for them to release enough energy to cause ignition, even in the event of a malfunction.

ATEX hearing aids still prioritise features and comfort

ATEX-certified hearing aids are equipped with features that meet the needs of those with hearing loss who work in harsh environments.  Features such as advanced Bluetooth, noise-cancelling, speech clarity and enhancement settings. 

Thus ensuring that you can communicate effectively and hear through the noise of machinery and equipment, as well as being alerted to any safety notices, without sacrificing your safety.

Hearing aids with ATEX certification are also some of the most comfortable hearing solutions you can wear, as they often feature an ergonomic design for all-day comfort.

The reality of wearing hearing aids in industrial environments

Working in a tough environment puts hearing aids through far more than a standard day at a desk. ATEX models are built for it — designed to cope with:

• High noise levels - Advanced noise reduction helps you hear speech clearly even with heavy machinery operating nearby
• Extreme temperatures - Functional in both very cold offshore environments and hot industrial processing areas
• Moisture and humidity - Sealed against water ingress, steam, and condensation
• Dust and debris - Protected against fine particles that would damage standard hearing aids
• Physical knocks and impacts - Robust housing that survives the rough and tumble of manual work
• PPE compatibility - Designed to work alongside hard hats, safety goggles, respirators, and other protective equipment

For information on ATEX hearing aids and employer responsibilities

If you employ someone with hearing loss who works in an ATEX environment, the law is fairly clear. The Equality Act 2010 places a duty on employers to make reasonable adjustments, and providing certified hearing aids that allow someone to do their job safely sits squarely within that. It's not optional.

Health and Safety at Work regulations reinforce this further, requiring that workers can hear safety warnings and communicate effectively in hazardous environments. For someone with hearing loss, ATEX hearing aids are often the only way to meet both requirements at once.

We work with occupational health teams across the UK to help employers navigate this — making sure the right hearing solution is in place for each individual, and that everything meets the necessary safety and regulatory standards. If you'd like to talk it through, we're here.

Understanding ATEX markings on your hearing aids

Your ATEX hearing aids will come with certification documentation that specifies which zones they're approved for. This typically appears as:

• Equipment Group II (for surface/non-mining use) or Group I (for mining)
• Category rating (1, 2, or 3)
• Zone compatibility (which zones you can safely wear them in)

For example, you might see: II 2G Ex ib IIC T4 Gb - This indicates equipment suitable for Zone 1 gas atmospheres. Your audiologist will provide you with an ATEX card that must be carried whenever you're wearing the hearing aids in hazardous areas. Your employer's health and safety team may also need to see this documentation for their records.

Definition of ATEX zones table

In brief, ATEX zones are locations where there is a risk of explosion or combustion.  For example, combustion dust will eventually build up over time and emit flammable gases.  This also determines how equipment in hazardous working environments is labelled and used, and potentially how long a worker can be in that atmosphere. 

Below, we highlight each ATEX zone, its definition, and the level of explosive atmosphere present.

Getting ATEX hearing aids through Hearing Aid UK

Getting fitted with ATEX hearing aids is a more straightforward process than most people expect. Here's how it works:

• Hearing assessment — A full assessment of your hearing alongside confirmation of your workplace ATEX zone classifications.
• Employer liaison — Where funding or subsidy is involved, we'll deal directly with occupational health or HR on your behalf.
• Choosing the right model — With only a small number of ATEX-certified options available, we'll match the right device to your hearing loss, your zone classification, and the realities of your working day.
• Fitting and programming — Set up specifically for your environment — not just standard settings from a quiet consultation room.
• Certification paperwork — All documentation provided, including your ATEX card to carry on-site whenever you're in a hazardous area.
• Follow-up in the real world — A second appointment after you've worn them at work, to fine-tune based on actual experience rather than assumptions.
• Long-term support — Ongoing servicing, adjustments, and parts for the life of your devices.

To arrange a consultation about ATEX hearing aids, call us free on 0800 567 7621. We can discuss your specific workplace requirements and help you understand whether employer funding might be available.
