ATEX, HAC & Dust Explosion Safety Services
Let us understand how we can help you
Indsafe provides specialized ATEX assessment, Hazardous Area Classification (HAC), and dust explosion safety services in India to identify ignition risks, classify hazardous zones, and ensure compliance with international safety standards.
These studies form a critical part of overall Process Safety systems, helping industries prevent fires, explosions, and catastrophic incidents.
WHAT IS ATEX & HAC
ATEX assessment focuses on identifying and controlling explosion risks in environments where flammable gases, vapors, or dust are present.
Hazardous Area Classification (HAC) involves classifying areas based on the likelihood and duration of explosive atmospheres, enabling proper selection of electrical and mechanical equipment.
Hazardous Area Classification (HAC)
Hazardous Area Classification (HAC) is the process of identifying and classifying areas where flammable gases, vapors, or dust may be present in sufficient quantities to create explosion risks.
These areas are categorized into zones based on the likelihood and duration of the presence of explosive atmospheres:
Zone 0 / Zone 20 – Continuous or long-duration presence of explosive atmosphere
Zone 1 / Zone 21 – Likely presence during normal operations
Zone 2 / Zone 22 – Unlikely occurrence or short duration
These zones are typically defined based on inputs from HAZOP studies and process risk assessments.
HAC plays a critical role in ensuring that appropriate electrical and mechanical equipment is selected and installed to prevent ignition in hazardous environments.
A well-executed HAC study helps industries:
• Prevent fire and explosion incidents
• Ensure compliance with ATEX and international standards
• Define safe equipment selection and installation practices
• Improve overall plant safety and reliability
IGNITION SOURCES
As per BS EN 1127, common ignition sources in industrial environments include:
- Hot surfaces
• Flames and hot gases
• Mechanical sparks
• Electrical equipment and faults
• Static electricity and electrostatic discharge
• Lightning
• Electromagnetic waves and radiation
• Chemical reactions
Understanding and controlling these ignition sources is critical to preventing explosion hazards.

DUST EXPLOSION RISK ASSESSMENT
Dust explosion risk assessment evaluates the potential of combustible dust to cause explosions under specific process conditions.
Key factors analyzed include:
• Dust explosibility (Kst value)
• Minimum Ignition Energy (MIE)
• Particle size and concentration
• Process conditions and confinement
These studies help identify explosion risks and implement preventive and mitigation measures.
ELECTROSTATIC HAZARD ASSESSMENT
Electrostatic discharge is one of the most common ignition sources in industrial facilities handling flammable materials.
Electrostatic hazard assessment evaluates:
• Charge generation and accumulation
• Discharge energy levels
• Material properties and MIE
• Grounding and bonding effectiveness
Proper control of electrostatic risks is essential to prevent ignition in hazardous environments.
