Every year, the HSE investigates hundreds of reportable industrial incidents across the UK. A significant number involve inadequate surveillance in high-risk zones, where a single spark from non-compliant equipment can trigger catastrophic consequences. For HSE Managers and Safety Officers, this is not a theoretical concern. It is an operational and legal reality.
Standard CCTV cameras are simply not built for environments where flammable gases, explosive dusts, or corrosive chemicals are present. Fitting the wrong camera in the wrong zone does not just create a safety risk. It creates a compliance failure that can lead to HSE enforcement notices, prosecution, or worse.
What separates a compliant hazardous area camera from an off-the-shelf unit is its ATEX or UKEX certification, its ingress protection rating, and the materials used in its construction. These are not optional upgrades. They are baseline requirements.
This guide gives HSE Managers and Safety Officers a clear framework for selecting hazardous area cameras across UK industrial sites, so your next audit is one less thing to worry about.
In UK industrial terms, a hazardous area is any location where flammable gases, vapours, mists, dusts, or fibers may be present in concentrations capable of causing an explosion. Under DSEAR, employers must classify these zones and ensure every piece of electrical equipment installed within them is rated accordingly.
A standard industrial camera, even one with a solid IP rating, is not designed to contain or prevent ignition. A hazardous area camera is. The difference lies in the protection concept built into the unit itself.
Industries that rely on compliant hazardous area CCTV across the UK include oil and gas refineries, chemical manufacturing plants, pharmaceutical processing facilities, offshore platforms, grain and flour mills, paint spray booths, and waste treatment sites.
Key protection concepts you will see on certified units include Ex d (flameproof enclosure), Ex i (intrinsically safe circuits), Ex e (increased safety), and Ex p (pressurised enclosure). Each is suited to different zone classifications and risk profiles.
It is also worth being direct about one common misconception: an off-the-shelf IP66 camera is not compliant for use in Zone 1 or Zone 2 classified areas. IP ratings address water and dust ingress. They say nothing about explosion protection.
Before Brexit, equipment used in explosive atmospheres across the UK was governed by the ATEX directive, specifically ATEX 114 (2014/34/EU). This EU legislation set out requirements for equipment and protective systems intended for use in potentially explosive atmospheres.
Since 1 January 2021, the UK has operated under its own domestic equivalent: UKEX. Enforced by the Health and Safety Executive, UKEX requires new equipment placed on the GB market to carry the UKEX (GB) marking. Products holding existing ATEX certification can still be used under transitional provisions, but this is an area Safety Officers should monitor carefully as the regulatory landscape continues to evolve.
The primary UK legislation governing explosive atmosphere risk remains the Dangerous Substances and Explosive Atmospheres Regulations 2002, known as DSEAR. Under DSEAR, employers are legally required to carry out zone classification, assess ignition risks, and ensure all installed equipment is appropriate for the zone in which it operates.
Zone classification works as follows. Zone 0 is where a gas or vapour explosion risk is present continuously or for long periods. Zone 1 is where it is likely to occur during normal operation. Zone 2 is where it occurs occasionally or in abnormal conditions. Zones 20, 21, and 22 are the dust equivalents of those three classifications.
When the HSE inspectorate conducts a site audit, non-compliant CCTV equipment is not overlooked. It can result in improvement notices, prohibition notices, or criminal prosecution under health and safety law. ATEX certified camera equipment carries markings indicating Equipment Group, Category, Gas Group (IIA, IIB, or IIC), and Temperature Class (T1 to T6). Understanding these markings is essential before any procurement decision.
Match the protection concept to the zone. Ex-d enclosures are common in Zone 1 applications. Ex e or Ex i designs may be appropriate for Zone 2. Never fit a lower-category unit in a higher-risk zone.
IP66 handles powerful water jets. IP67 covers temporary immersion. IP68 is rated for continuous submersion. In wet, dusty, or washdown-heavy UK environments, at least IP66 is expected, but the IP rating must accompany, not replace, explosion protection certification.
UK installations vary enormously. North Sea platforms, outdoor refineries, and cold-storage facilities all demand cameras that function reliably from around -40 degrees Celsius to +75 degrees Celsius.
Hazardous areas are often poorly lit. Low-lux sensors and integrated infrared capability ensure usable footage during night shifts or in unlit plant areas.
Look for certificates issued by recognised UK notified bodies such as SGS-Fimko, Intertek, or Bureau Veritas. Always request a full certificate of conformity, not just a product datasheet.
Marine-grade stainless steel or GRP (glass-reinforced plastic) housings are essential for offshore, coastal, and petrochemical sites where corrosion is a constant threat.
Confirm that any explosion proof CCTV camera supports ONVIF protocols. This ensures compatibility with the Video Management Systems already in use at most UK industrial facilities.
Relying on IP Rating Alone: IP68 is not explosion proof. This confusion is widespread in procurement teams and leads to non-compliant installations that will not survive an HSE audit.
Buying from Grey-Market Suppliers: Uncertified or counterfeit explosion proof surveillance cameras are a serious legal and physical risk. In post-UKEX Britain, equipment without valid certification documentation should not be considered.
Incorrect Zone Mapping: A Category 3 camera is rated for Zone 2. Fitting it in a Zone 1 area is a direct regulatory violation. Zone classification must happen before product selection, not after.
Ignoring Temperature Classification: If a T4-rated camera is installed near a substance with an ignition temperature below 135 degrees Celsius, the installation is non-compliant regardless of every other specification being correct.
Overlooking Maintenance Requirements: Explosion proof equipment must be serviced by certified engineers. Many buyers focus on purchase price and ignore ongoing maintenance costs, which can be significant.
Hazardous area CCTV is not a standalone solution. It works as one layer within a multi-barrier safety approach alongside gas detection systems, emergency stop systems, and permit-to-work processes.
Video evidence from atex zone 1 camera installations supports incident investigations under RIDDOR reporting obligations, giving safety teams a documented record of events leading up to any reportable incident.
Remote monitoring is another major benefit. IP-based hazardous area cameras allow Safety Officers to observe high-risk zones without placing personnel in dangerous environments, particularly during start-up, shutdown, or abnormal operating conditions.
Around tank farms, compressor stations, and chemical storage areas, these cameras also support perimeter intrusion detection, adding a layer of physical security to the safety monitoring plan.
From an audit perspective, continuous recording demonstrates due diligence under the Health and Safety at Work Act 1974 and strengthens your position during any HSE inspection.

A UK refinery with multiple Zone 1 process areas had failed a DSEAR audit due to non-certified cameras. ATEX Category 2 PTZ cameras with stainless steel housings were installed, delivering 24/7 visual oversight. The site passed its subsequent HSE inspection.
A solvent-handling GMP site required surveillance inside Zone 2 filling rooms. Fixed explosion proof dome cameras with IIB gas group certification and T4 temperature classification were deployed, satisfying both UKEX and GMP documentation requirements.
A flour mill with Zone 21 dust-classified areas needed cameras resistant to combustible dust and industrial washdown. ATEX certified IP67-rated dust-zone cameras were fitted at conveyor transfer points and silos, reducing blind spots significantly.
An operator upgraded cameras across a jacket platform with Zone 1 and Zone 2 deck areas. Marine-grade ATEX and UKEX dual-certified units with integrated IR and IP68 rating were specified to handle salt spray, wind, and extreme temperatures.
The takeaway for HSE Managers is consistent: no two hazardous area installations are the same. Camera selection must always begin with zone classification, substance identification, and site conditions, not product availability or budget alone.
ATEX is the EU directive. UKEX is the UK domestic equivalent introduced post-Brexit. Existing ATEX-certified equipment can still be used in the UK under transitional provisions, but new equipment entering the GB market must carry UKEX (GB) marking.
Any industry operating classified explosive atmosphere zones under DSEAR, including oil and gas, chemicals, pharmaceuticals, food processing, offshore, and waste management.
No. IP ratings only address ingress protection. Zone 1 and Zone 2 areas require ATEX or UKEX certified cameras with appropriate explosion protection concepts.
Zone 1 is where an explosive gas atmosphere is likely during normal operation. It requires Category 2 certified equipment as a minimum.
Under BS EN IEC 60079-17, initial inspection should occur at commissioning, with periodic inspections typically every one to three years depending on environment and risk assessment.
Temperature class (T1 to T6) indicates the maximum surface temperature the camera can reach. It must be lower than the ignition temperature of the substances present on site.
Zone classification should be conducted by a competent person following BS EN 60079-10. It involves identifying hazardous substances, release sources, and ventilation conditions across the site.
Yes. SharpEagle supplies marine-grade, ATEX and IECEX certified cameras specifically designed for offshore environments, including North Sea platforms.
