Modular Design: Advantages of Detachable and Combinable Hoods, Face Shields, and Gloves

In high-voltage power, rail transit, and industrial automation environments, arc flash protective clothing is a critical piece of equipment for ensuring worker safety. As work scenarios become increasingly complex, the concept of modular design has emerged as a key trend in arc flash clothing. By allowing detachable and combinable hoods, face shields, and gloves, modular arc flash clothing achieves a balance of protection, comfort, and flexibility.

1. Core Principles of Modular Design

Flexible Combination to Meet Different Risk Levels

• Operators can select full or partial protective modules based on the arc flash risk level (ATPV/EBT value).

• For example, during low-risk inspections, only a face shield and gloves may be used, while high-voltage live work requires the full combination of hood, face shield, and gloves for maximum protection.

Convenient Detachment for Efficient Donning and Doffing

• Modular design allows workers to quickly attach or remove key components, improving on-site emergency response.

• Hoods, face shields, and jackets are connected via quick fasteners or zippers; gloves can be independently worn or removed, reducing replacement time.

Enhanced Comfort and Ventilation

• In high-temperature or enclosed environments, detachable hoods and face shields improve airflow and heat dissipation, reducing the risk of heat stress or fatigue.

• During mobility-intensive or low-risk tasks, reducing module weight increases operational flexibility.

Modular Maintenance and Management

• Each module can be independently cleaned, replaced, or repaired, extending the overall lifespan of the protective clothing.

• Labels and traceability systems track usage and maintenance for each module, aiding in safety management.

2. Key Modules and Functions

Hood (Arc Flash Hood)

• Protects the head, neck, and shoulders from thermal radiation and molten metal splashes.

• Can be combined with a face shield for full-face visibility and protection.

Face Shield

• Guards against molten metal splashes, intense light, and shockwaves, protecting the eyes and facial skin.

• Adjustable and detachable to accommodate different work postures.

Gloves (Arc Flash Gloves)

• Resist high-temperature splashes and localized arc impacts, protecting fingers, backs of hands, and wrists.

• Modular design allows easy removal and replacement, improving hygiene and durability.

3. Advantages of Modular Design in Industry

• Power Industry: Flexible module combinations during high-voltage inspections in substations and distribution rooms provide both protection and operational efficiency.

• Rail Transit: In metro and urban rail repairs, modular design reduces weight in confined spaces, improving mobility and efficiency.

• New Energy: Modular combinations adapt to limited space and varying voltage levels during photovoltaic, energy storage, and battery cabinet maintenance.

• Industrial Manufacturing: For high-voltage machinery and electrical automation maintenance, modules can be selected based on localized arc flash risks for targeted protection.

4. Conclusion

Modular design makes arc flash protective clothing smarter, more flexible, and safer.
By allowing hoods, face shields, and gloves to be detached and combined as needed, workers can achieve efficient protection, comfortable operation, and convenient management according to risk level, environmental conditions, and operational requirements.
