Hazardous Areas Inspections

OCS Group’s hazardous area equipment management program is a detailed process involving multiple services including 3rd party hazardous area equipment inspections.

This inspection service ensures the equipment integrity is not compromised and is compliant to both statutory and international standards for electrical installations where potentially explosive atmospheres exist for both new and existing builds.

The risk of a catastrophic explosion within a hazardous area (gas, vapor, or dust) is significantly increased if it is not managed correctly and inspected/maintained on a regular basis by competent personnel.

Correct Hazardous Area Equipment management doesn’t unnecessarily increase costs and in fact will improve efficiency and lower risk. OCS Groups Hazardous Area Management Program responds to this concern by providing a lifecycle of processes that maintains the safety integrity of the equipment at the same time as reducing cost.

Our Hazardous Area Inspections will develop a complete dossier that will comply at all Regulatory Authority requirements, that includes;

  • Creating a Register of all equipment and essential information
  • Develop an ITR for each piece of equipment
  • Identify all corrective actions with photographs of equipment and problems
  • Manage all certificates of the equipment
  • Maintain the hazardous area zone drawings
  • If required develop and conform to Maintenance strategies
  • Record the inspection and equipment history

The end result is full compliance and accountability with complete details of the inspection and equipment history.

OCS also supplies full support to manage and complete all corrective actions (Remedial Work).


CFR 1910.307(b) – USA

 IEC 60079-17 Part 4 – (Where Applicable)

Documentation: For the purposes of inspection and maintenance, up-to-date documentation of the following items shall be available:

  • Zone classification of areas and, if included, the equipment protection level (EPL) required for each location (see IEC 60079-10 and IEC 61241-10),
  • For gases: equipment group (IIA, IIB or IIC) and temperature class requirements,
  • For dusts: equipment group (IIA, IIB or IIIC) and maximum surface temperature requirements,
  • Equipment characteristics e.g. temperature ratings, type of protection, IP rating, corrosion resistance,
  • Records sufficient to enable the explosion protected equipment to be maintained in accordance with its type of protection (see IEC 60079-14 and IEC 61241-14), (for example list and location of equipment, spares, certificates, technical information),
  • Copies of previous inspection records.

Requirements for other documentation that may be necessary are provided in IEC 60079-14, IEC 60079·19 and IEC 61241-14.
