Arc Flash Clothing in the Chemical & Petrochemical Industry

– Dual Protection for Live Operations and Explosion-Risk Environments

The chemical and petrochemical industries are characterized by high temperature, high pressure, flammable and explosive conditions. Whether performing live operations at tank pump stations or conducting maintenance on explosion-proof electrical cabinets, workers face multiple simultaneous risks—including arc flash, extreme heat, molten metal splashes, pressure shockwaves, chemical corrosion, and ignition of volatile gases.

In such environments, arc flash clothing is not just protective apparel—it is a vital barrier against secondary explosions and severe bodily harm.

✅ 1. High-Risk Operational Scenarios

Live Work at Tank Pump Stations

• Switchgear control operations

• Motor circuit testing

• Maintenance of transmission lines for oil/gas

• Inspection of lighting and power devices in hazardous zones

Typical risks:

• Loose terminals causing sudden short circuits

• Oil contamination or humidity leading to insulation failure

• Arc flash triggering ignition of vapors or combustible gases

Maintenance of Explosion-Proof Electrical Cabinets

• Inspection of PLC control panels

• Opening explosion-proof junction boxes

• Servicing MCCs (Motor Control Centers)

• Voltage and power circuit testing

Typical risks:

• Arc discharge within confined explosion-proof chambers

• Breaker failure causing molten splatter

• Shockwave injuries to the head, face, and upper body

✅ 2. Combined Hazards: Arc Flash + Chemical Environment

In these situations, standard flame-resistant clothing is insufficient. Only certified arc flash garments can defend against the combined threats of heat, blast, chemicals, and ignition.

✅ 3. Key Protective Features of Arc Flash Clothing

✔ High-Temperature and Thermal Shock Resistance
Certified ATPV/EBT energy protection levels (8–40 cal/cm² optional), preventing skin burns from arc flash.

✔ Protection Against Molten Splash & Pressure Shockwaves
Reinforced structure reduces the impact of hot metal particles and explosion overpressure.

✔ Anti-Static, Self-Extinguishing, and Non-Melting Fabric
Prevents secondary injuries caused by fabric ignition or melting onto skin.

✔ Compatible with Explosion-Proof PPE
Easily worn with respirators, helmets, arc-rated gloves, and face shields.

✔ Supports Live Maintenance
Meets IEC, ASTM, NFPA, EN, and Chinese arc protection standards.

✅ 4. Suitable Personnel

• Electrical and instrumentation inspectors in tank zones

• Maintenance technicians at oil/gas pump stations

• Electricians in hazardous areas

• Petrochemical equipment operators

• Explosion-proof cabinet maintenance engineers

• Control system technicians

• Emergency power repair teams

✅ 5. Recommended Arc Protection Levels (Based on Risk Level)

✅ 6. Safety Reminder

In the chemical and petrochemical industry, the true danger often doesn’t come from the arc flash itself—but from what it ignites.

Arc flash clothing is not worn for emergencies — it's worn to stay alive.
When working around storage tanks, pump rooms, or explosion-proof electrical cabinets, safety isn't just about experience. It’s about the right protective gear.
