Arc protection hood 47.0 cal/cm²

The HRC 4 Arc Protection Hood (47.0 cal/cm²) provides advanced thermal protection for the head, face, neck, and shoulders when working close to live electrical parts or in high-risk arc-flash zones. Tested to top industry standards and approved for live work, this hood is a critical part of a comprehensive arc-flash PPE system. 

With its ATPV 47.0 cal/cm² rating, integrated hard hat and true-colour visor, it supports both compliance and safety performance without compromising visibility or wearability.

It’s ideal for electrical engineers, high-voltage technicians, and safety-critical teams tasked with live working under safe-system-of-work policies, particularly where substations, switchgear and distribution panels present elevated hazard risk.

• Size: Universal / one size fits most
• Approved For: Live working environments

 

Expanded Applications & Suitability

This arc protection hood is engineered for high-energy electrical tasks where the arc flash hazard exceeds typical PPE Category 2 or 3 levels. It is especially suitable for:

• Substations & electrical switching rooms
• HV/LV switchgear operation and maintenance
• Panel racking and de-racking operations
• Testing and diagnostics near live parts
• Industrial and utility power distribution work

Used in conjunction with arc-flash jackets, gloves, and other PPE, this hood supports safe working practices when strict arc-flash risk assessments indicate exposure to incident energy above 40 cal/cm².

 

Standards & Compliance

The Arc Protection Hood meets or is tested against multiple international arc flash standards that electrical safety professionals trust:

• ASTM F2178 – Arc Thermal Performance Value (ATPV): Certified at 47 cal/cm², indicating the level of incident energy that the hood fabric can withstand before second-degree burn.
• CSA Z462 / OSHA 1910.269: Recognised arc flash PPE standards supporting compliance and worker protection.
• IEC 61482-1-1 ATPV: International arc flash test standard.

The ATPV value is essential for safety teams when justifying PPE selection following a formal arc flash risk assessment. An ATPV of 47 cal/cm² ensures coverage well beyond the traditional 40 cal/cm² threshold for Hazard Risk Category 4 PPE, helping employers meet their legal duty of care obligations under UK and international electrical safety regulations.

 

Compatibility & System Use Guidance

This arc flash hood is designed to integrate into a full PPE strategy:

• Hard Hat Compatibility: Integrated hard hat and bracket ensure secure mounting and combined protection.
• Layered PPE System: Works best when paired with arc-rated jackets/coats, trousers and gloves rated to similar or greater ATPV levels.
• Vision: True colour visor preserves colour recognition necessary for safe live working.

To maximise safety, always coordinate hood use with documented lockout/tagout procedures and confirmed hazard boundaries.

 

Comfort & Usability Benefits

• True Colour Visor: Maintains accurate colour perception to assist in safe decision-making on site.
• Anti-static Fabric: Reduces static build-up in dry environments.
• Universal Fit: One size accommodates a range of head dimensions without compromising protective integrity.
• Robust Construction: Double-layer anti-static cotton balances protection with breathability for extended use.

These ergonomic features help encourage consistent, correct usage even during prolonged work periods.

 

Care, Maintenance & Inspection Advice

To maintain protective performance and compliance:

• Inspect Each Use: Check the visor for cracks, scratches, or distortion; inspect the seams and fabric for wear.
• Clean Carefully: Follow manufacturer guidance; avoid harsh chemicals that could degrade FR performance.
• Storage: Store in a clean, dry environment away from UV exposure.
• After Exposure: Remove from service if the hood has undergone an arc flash or shows damage.

Routine checks and controlled storage help ensure the hood remains ready for use when safety matters most.

 

Summary

This Arc Protection Hood is engineered and tested to high industry standards trusted by UK and international safety professionals, making it suitable for duty-of-care PPE programs following arc flash hazard assessments. Its use supports compliance with recognised standards and best practices when paired with comprehensive safe working procedures, including Lockout Tagout and live working controls. 

 

FAQs

Is this hood suitable for live electrical work?

Yes. It is approved for live working in environments assessed to require HRC 4 arc flash protection.

What does 47.0 cal/cm² mean?

It refers to the ATPV (Arc Thermal Performance Value), which quantifies the incident energy the hood can withstand before thermal injury. Higher values denote greater protection.

Can this hood be worn with other arc flash PPE?

Yes. It should be used as part of a complete arc flash PPE system, including jackets, gloves and trousers rated to a similar ATPV.

Does the visor affect colour perception?

No. The true colour arc-rated visor maintains accurate colour recognition to support safer operations.

Is one size truly universal?

The design accommodates most head sizes while providing proper protective coverage.
