ZONE 2 CERTIFICATION IN UAE
Areas classified as zone 2 are those where potentially explosive atmospheres, including hydrocarbon or H₂S gas leaks, are not anticipated during regular operations but could happen momentarily. There is a significant risk of fire or explosion from these gases. Strict Zone 2 compliance criteria have been implemented by ADNOC and international standards to reduce such risks and guarantee the security of people and equipment. Among these are the application of mechanical and electrical systems that are inherently safe and intended to avoid igniting. By providing sturdy, field-tested Zone 2 installations that adhere to ADNOC’s safety regulations, we support your compliance demands. Our specialized zone certification and hazardous area classification services in the UAE for offshore rigs and platforms. Ex-survey and explosion-proof surveys of transformers and generators come under the scope of ATEX or CompEx certification. Get ADNOC-approved Zone 2 certification and CompEx and ATEx certification services with hazardous area classification and Ex survey. We provide Zone classification in ADNOC and Zone II certification for electrical and marine equipment of engines, generators, motors, cranes, winches, and forklifts across UAE.
- The most generally recognized international standard for equipment used in explosive atmospheres is the IEC 60079 Series (International, or IECEx).
- ATEX Certification (projects headquartered in the EU) If conducting business in Europe or in accordance with ATEX-aligned regulations: Equipment and protection systems designed for use in potentially explosive environments are covered by Directive 2014/34/EU (ATEX 114). Equipment in Zone 2 must adhere to Category 3G specifications: II 3G Ex nA IIC T4 Gc is the marking.
- IECEx Certification (Asia, Middle East, UAE, and Worldwide). Like ATEX, but with international recognition. Equipment is inspected and certified by IECEx CBs (Certification Bodies). IECEx-issued Certificates of Conformance adhere to IECEx requirements via ESMA or ADNOC recommendations.
- MoIAT now oversees the Emirates Authority for Standardization and Metrology (ESMA). Internal HSE Guidelines from ADNOC, ENOC, and other NOCs include reference to ATEX/IECEx and IEC 60079 regulations. Equipment in hazardous areas must undergo third-party certification and inspection. The Hazardous Area Classification (HAC) report and zone classification drawings are necessary.
ZONE CLASSIFICATION IN ADNOC
ADNOC follows international codes and standards to classify all the hazardous areas where to control the explosive atmosphere and to estimate the severity of flammable gas/vapors that may exist in the atmosphere. All the marine and electrical equipment’s which are used in ADNOC zones/area are certified as fit to use even if it is in non-hazardous pockets. Zone classification required equipment must be certified according to the requirements of Intrinsic safety(Ex i), Flame proof enclosures (Ex d), Increased safety (Ex e), Pressurized (Ex p)or Encapsulation(Ex m).
Zone II certification is design for all the electrical and marine equipment of engines, generators and motors. Lifting Equipment’s and Lifting accessories of Deck cranes, winches and forklifts with suitable Ex/ATEX Certification are used in offshores. Low power devices of sensors, alarms, and non-sparking producing tools are also used in Zone classifies areas.
HAZARDOUS AREA CLASSIFICATION IN UAE
A hazardous area is a three-dimensional location where there is or may be an anticipated presence of a flammable or explosive environment in such quantities to necessitate ignition source controls in order to manage safety concerns (i.e., fires and explosions). Explosions and fires can have disastrous effects on people and property, leading to probable loss of business as well as fatalities or severe injuries. As a result, a person conducting a business or undertaking (PCBU) is subject to a duty of care under electrical safety and work health and safety laws.
HACs can be performed using more quantitative techniques that necessitate in-depth plant knowledge or by directly comparing them with typical installations as defined by existing codes. Additional assistance from other hazard identification procedures, such as a Hazard and Operability Study (HAZOP) and a Preliminary Hazard Analysis (PHA), as well as computations using specialized modeling software, may be required for HACs for new or complicated installations. Manufacturers’ safety data sheets (SDS) or other representative data on the explosive characteristics of the flammable materials involved must always be used to support HACs. Testing to ascertain the dust’s explosive characteristics, such as particle size and chemical makeup, may be necessary for HACs containing flammable dust.
