Questions and Answers
- What are the key differences between intrinsically safe (Ex I) and explosion-proof (Ex d) pipe inspection equipment?Both explosion-proof and intrinsically safe pipe-inspection robots comply with ATEX Zone 1 regulations, yet they operate on different safety principles.
An intrinsically safe (Ex i) robot ensures that every circuit operates at such low voltage and current that it can never spark or reach a surface temperature capable of igniting surrounding gas. With their electronics running on milliamps, these systems typically can not provide sufficient illumination and image quality in the inspection area.
On the other hand, explosion-proof (Ex d) pipe inspection systems take a different approach. They allow for higher-powered motors, batteries, and lighting, but these components are securely sealed inside a rugged metal enclosure featuring threaded joints or flame paths. If an internal ignition occurs, the housing contains the pressure and cools the hot gases, preventing anything from escaping into the atmosphere.
In practice, if your priorities are maximum lighting, better image quality, high-torque, and heavy-duty durability, then an explosion-proof crawler would better suit your needs. Both protection concepts comply fully with ATEX Zone 1; the right choice depends on your needs and requirements. - Which UL standard provides an equivalent level of protection to ATEX Zone 1 certification?The closest direct match to ATEX Zone 1 is a piece of equipment that is UL-listed for Class 1, Division 1 (C1D1)—or, under the newer harmonised scheme, UL Class 1, Zone 1. Class I tells inspectors that the hazard is a flammable gas or vapour. At the same time, Division 1 / Zone 1 means that an ignitable atmosphere will likely be present during normal operation, which is exactly the condition ATEX defines for Zone 1.
- Are operators required to hold specific training or licenses to deploy an explosion-proof pipe-inspection crawler?Operators of explosion-proof pipe crawlers are not required to obtain a special government-issued license. However, legislation stipulates that any individual who operates powered equipment in hazardous areas must possess the necessary competency and formal training in explosive-atmosphere safety.
In North America, the Occupational Safety and Health Administration (OSHA) regulations, as outlined in 29 CFR 1910.307, along with the Canadian Electrical Code, indicate that electrical equipment utilized in Class 1, Division 1 environments (which corresponds to the UL/CSA equivalent of ATEX Zone 1) must be installed and serviced by qualified personnel. This designation refers to workers who have completed hazards-specific training and can demonstrate their ability to identify and mitigate ignition risks. While individual states or provinces may impose additional requirements regarding confined space entry, hot-work operations, or gas-testing certifications, there remains no distinct "crawler operator license."
In summary, a crew is not required to possess a specialized government license to operate the pipe robot. Nonetheless, it is imperative that they have documented training related to hazardous areas, compliant with either ATEX or OSHA standards, as well as any customer-mandated certifications, such as CompEx. It is essential to demonstrate competence, adhere to the permit system, and ensure that the Explosion Protection Document is kept current. - What are the required inspection intervals for ATEX Zone 1-certified explosion-proof pipe crawlers to maintain compliance?To maintain compliance, adhering to specific inspection intervals for ATEX Zone 1-certified equipment is essential. The ATEX and IEC standards regard inspection as a life-cycle requirement, rather than a singular occurrence. Below are the mandated practices for equipment designed for C1Z1/C1D1 applications, such as a pipe inspection robot:
- Initial Detailed Inspection Before First Use: A qualified Ex technician must conduct a comprehensive assessment to ensure that the crawler’s protection concept, markings, and installation conform to the site's Explosion Protection Document. This initial examination is mandated by EN / IEC 60079-14 and must be completed and documented before the robot is permitted to operate within a Zone 1 environment.
- Shortened Intervals for Movable or Portable Ex Equipment: As a pipe crawler is classified as movable electrical equipment, IEC 60079-17 recommends a maximum interval of twelve months between close inspections, supplemented by a brief visual check by the operator each time it is deployed in a hazardous zone. Adverse conditions, frequent openings of enclosures, or a history of rough maintenance may warrant even shorter inspection intervals.
- May any repair facility service ATEX Z1-certified explosion-proof pipe inspection robots, or must work be carried out exclusively by accredited Ex service centres?The answer is negative; you cannot simply deliver a Proteus™ ExZ1 explosion proof pipe crawler to any local shop and anticipate that the certification will remain valid. Once equipment is placed on the market, any repairs, overhauls, or modifications that may affect its explosion protection features must be performed by a workshop that adheres to the requirements of IEC 60079-19 and operates under a documented Ex-quality system.
Should an unqualified workshop open the Ex d enclosure, replace a gland, or re-pot an Ex i board without these controls in place, the protection concept will be deemed "no longer verified." Consequently, the crawler will:
1. Lose its ATEX certification until it undergoes re-testing and re-certification by a notified body.
2. Face possible exclusion from any Zone-classified plant as determined by the site's permit-to-work team or insurer.
Field services are only permissible for straightforward, low-risk tasks, such as replacing a user-replaceable battery, when explicitly sanctioned by the manufacturer's instructions and signed off by a CompEx-qualified individual. Any alteration that disrupts flame paths, encapsulation, or intrinsic safety barriers must be directed back to an Ex-compliant service center.
In summary, disassembling the camera, coiler, control unit, or any part of the Proteus™ ExZ1 explosion-proof pipe inspection robot without the manufacturer's approval is forbidden!
Only Minicam-certified appointed Service Centres are permitted to perform any servicing, internal examination, or any repairs on ATEX equipment. You must not have the equipment serviced, internally examined, or repaired by an unauthorised person. Not only will this invalidate any warranty, but it can also immediately invalidate any ATEX compliance certification.

Explosive Atmosphere and Visual Inspection
Explosive Environments & ATEX Zone 1—Key Concepts
What qualifies as a “hazardous location”?
Any area where flammable gases, vapours, liquids, dusts, or fibres could mix with air and find an ignition source is deemed hazardous. Typical culprits include gasoline, paint thinners, naturally occurring hydrocarbons, decomposing organic matter, and similar substances. When oxygen, fuel, and an ignition source coexist, fire or explosion is possible.
Our explosion-proof pipe inspection robots are certified for ATEX Zone 1 service (IECEx analogue of Class I, Division 1 in North America, as defined by NFPA 70 / NEC). No pipe-inspection robot on today’s market is rated for ATEX Zone 0 or carries full intrinsic-safety approval, so users must confirm the classification of every work site before deployment.
What does “explosion-proof” actually mean?
Under NFPA 70 (NEC) the term describes an enclosure built to contain an internal ignition and prevent flames, sparks or hot gases from reaching the surrounding atmosphere. It is not designed to survive an external blast; instead, it stops a small internal event from becoming a large external disaster.
Explosion-proof apparatus must also respect the installation's temperature code - its surface temperature in normal service may never exceed the ignition point of ambient gases or dusts.
North American classification system (Class / Division)
Class I – Flammable gases or vapours may exist.
Class II – Combustible or conductive dust is present.
Class III – Easily ignitable fibres or flyings are present.
CI D1 Hazard is present under normal conditions.
CI D2 Hazard appears only under abnormal or infrequent conditions.
Equipment approved for CI D1 is automatically acceptable in CI D2 areas of the same class, gas group and temperature rating.
International (Zone) classification now adopted by the US & Canada
Zone 0 – Explosive atmosphere continuously or for > 1,000 h/yr.
Zone 1 – Explosive atmosphere likely in normal operation (≈ 10–1,000 h/yr).
Zone 2 – Explosive atmosphere unlikely or only for < 10 h/yr.
ATEX Zone 1, therefore, matches Class I, Division 1 for gas hazards.
Explosion-proof equipment, being the highest gas-hazard category, can always be installed where Division 2 or Zone 2 standards apply, provided the gas group and temperature class match.

Typical culprits include gasoline, paint thinners, naturally occurring hydrocarbons, decomposing organic matter, and similar substances. When oxygen, fuel, and an ignition source coexist, fire or explosion is possible.
Our explosion-proof pipe inspection robots are certified for ATEX Zone 1 service (IECEx analogue of Class I, Division 1 in North America, as defined by NFPA 70 / NEC). No pipe-inspection robot on today’s market is rated for ATEX Zone 0 or carries full intrinsic-safety approval, so users must confirm the classification of every work site before deployment.
What does “explosion-proof” actually mean?
Under NFPA 70 (NEC) the term describes an enclosure built to contain an internal ignition and prevent flames, sparks or hot gases from reaching the surrounding atmosphere. It is not designed to survive an external blast; instead, it stops a small internal event from becoming a large external disaster.
Explosion-proof apparatus must also respect the installation's temperature code - its surface temperature in normal service may never exceed the ignition point of ambient gases or dusts.
North American classification system (Class / Division)
Class I – Flammable gases or vapours may exist.
Class II – Combustible or conductive dust is present.
Class III – Easily ignitable fibres or flyings are present.
CI D1 Hazard is present under normal conditions.
CI D2 Hazard appears only under abnormal or infrequent conditions.
Equipment approved for CI D1 is automatically acceptable in CI D2 areas of the same class, gas group and temperature rating.
International (Zone) classification now adopted by the US & Canada
Zone 0 – Explosive atmosphere continuously or for > 1,000 h/yr.
Zone 1 – Explosive atmosphere likely in normal operation (≈ 10–1,000 h/yr).
Zone 2 – Explosive atmosphere unlikely or only for < 10 h/yr.
ATEX Zone 1, therefore, matches Class I, Division 1 for gas hazards.
Explosion-proof equipment, being the highest gas-hazard category, can always be installed where Division 2 or Zone 2 standards apply, provided the gas group and temperature class match.

What is an explosion-proof pipe inspection robot, and what are its applications in various industries?
An explosion-proof pipe crawler is a remote-controlled robotic platform that carries a high-resolution camera, lighting, and optional sensors through pipelines for inspection and survey purposes in hazardous (ATEX Zone 1/ UL CI D1) atmospheres. Its sealed flame-proof (Ex d) or intrinsically safe (Ex i) enclosure contains any internal spark or hot surface, so the robot can operate where flammable gases, vapours, or combustible dusts are present without becoming an ignition source. By keeping inspectors safely outside the hazard zone and eliminating plant shutdowns for manual entry, it delivers fast, detailed visual data while guarding both personnel and production uptime.
