HAZARDOUS AREA CLASSIFICATIONS (HAC) CONSULTANCY
The Hazardous (Classified) Location Study aims to assess and mitigate fire and explosion risks in general industries where hazardous substances such as flammable liquids, gases, vapors, and combustible dusts are present. Unlike chemical industries, where these risks are well recognized, general industries often overlook hidden hazards associated with limited but critical usage of hazardous materials in their operations. This study, conducted by JASP Resources Sdn Bhd, ensures compliance with international safety standards (NFPA, IEC, ATEX), enhances occupational health & safety, and helps businesses optimize capital expenditure while reducing legal liabilities.
Hazard Identification & Risk Assessment
- Identify the types of hazardous substances present.
- Assess environmental conditions, such as temperature and humidity.
- Categorize the risk of explosive atmospheres (e.g., gas, dust)
Classification of Hazardous Locations
- Class I – Areas with flammable gases and liquids.
- Class II – Areas with combustible dust risks
Zoning of Classified Locations
- Zone 0 / 1 / 2 (for flammable gases and vapors).
- Zone 20 / 21 / 22 (for combustible dust atmospheres).
- Defining horizontal & vertical zone extensions for precise safety mapping.
Assessment of Electrical Equipment in Hazardous Zones
- Reviewing installed electrical equipment (e.g., Ex d IIBT3 classification).
- Evaluating proper installation (location, conduit, sealing methods, etc.)
Identification of Compliance Deviations
- Checking for non-compliant or outdated electrical installations.
- Highlighting risks related to inadequate grounding, shielding, or sealing.
Corrective Action Recommendations
- Developing site-specific corrective measures for non-compliant areas.
- Providing guidance on upgrading installations to meet global safety norms.
The study focuses on three core principles to prevent explosions and fires:
Primary Explosion Protection Prevent formation of ignitable atmospheres
Secondary Explosion Protection Prevent ignition sources from triggering an explosion
Tertiary Explosion Protection Minimize explosion impact through containment & mitigation strategies

ARC FLASH CONSULTANCY & SAFETY ASSESSMENT
We work with our Partner, Gloabl Risk Experts, provide comprehensive arc flash assessments, including risk evaluations, analysis of electrical systems, and the development of safety protocols. Our arc flash consultancy ensures that your organization is compliant with electrical safety regulations and mitigates the risks associated with arc flash incidents. Arc flash incidents occur when there’s an electrica fault, releasing dangerous energy that can cause injury or death. JASP Resources Sdn Bhd conducts Arc Flash Risk Assessments, providing a detailed analysis and safety strategies to minimize the risk.
Assessment Steps
- Assess the electrical distribution system, including circuit breakers, ransformers, and relays.
- Calculate incident energy levels to determine the necessary PPE.
CHRA METHODOLOGY & STEPS
- Ensure protective devices (circuit breakers, fuses) are coordinated to limit fault duration.
- Adjust settings for optimal protection and minimal damage in case of faults.
CHRA METHODOLOGY & STEPS
- Assess the electrical distribution system, including circuit breakers, ransformers, and relays.
- Calculate incident energy levels to determine the necessary PPE.
Safety Audits & Compliance Review
- Perform arc flash safety audits to ensure compliance with NFPA70E, OSHA, and IEC 61892.
Training for Workers
- Conduct training sessions on recognizing arc flash risks, wearing proper PPE, and following safe working practices.
ARC FLASH & ELECTRICAL SHOCK HAZARD
An Arc Flash is a high-energy electrical explosion that occurs when current travels through air between conductors or from a conductor to ground. It is one of the most dangerous electrical hazards, releasing intense heat, light, sound, and pressure waves. These explosions can vaporize metal, ignite fires, and seriously injure or kill workers nearby.
Electric Shock, while different, is equally hazardous. It happens when a person becomes a path for electrical current due to poor insulation, faulty equipment, or inadequate protective grounding.
Assessment Steps
If your facility operates equipment above 50 volts, you are exposed to the risk of arc flash. Regulatory bodies such as OSHA, NFPA, and IEEE mandate that employers identify, assess, and mitigate electrical hazards.
Failure to comply can result in:
- Employee injuries or fatalities
- Equipment destruction and fire
- Insurance claims or lawsuits
- Fines, citations, and operational shutdowns
- Reputational damage
JASP Resources Sdn Bhd provides comprehensive Arc Flash Risk Assessments to help your organization remain compliant, safe, and efficient.
