Portwest Arc Flash Visor Class 2

Certified arc flash face protection for live electrical work and proximity hazards. The Portwest PS93 Arc Flash Visor Class 2 is engineered to shield eyes and face against the combined mechanical and thermal hazards generated by an arc flash event — one of the most dangerous and unpredictable risks in electrical installation, maintenance, and energy distribution work.

The visor is injection moulded from high-performance polycarbonate, delivering exceptional optical clarity, colour recognition, and visibility in the field. The innovative grey tinted face shield not only provides effective arc flash protection but enables easy colour identification across teams and job sites, supporting rapid visual compliance checks at a glance. An ergonomically designed transparent chin guard completes the face coverage while allowing unrestricted jaw movement — important for extended periods of wear during live working procedures.

The PS93 is supplied with a fire retardant carrier designed to fit 30mm helmet slots, compatible with Portwest Endurance (PS53) and Height Endurance (PS54) helmets. The carrier is engineered for balanced flip-up positioning, distributing the weight of the visor optimally to reduce neck fatigue during prolonged use. The flip-up design allows workers to raise the visor quickly between tasks without removing their helmet or disrupting their workflow.

Carrying an impressive range of international certifications — including EN 166, EN 170, GS ET 29 Class 2, ANSI/ISEA Z87+, ASTM F2178 at ATPV 14 cal/cm², and NFPA 70E PPE Category 2 — the PS93 meets the stringent demands of professional electrical contractors, utilities engineers, and facilities maintenance teams operating under arc flash risk assessment protocols worldwide.

For use with non-vented, Category III helmets only.

What hazards does the Portwest PS93 arc flash visor protect against? The PS93 is designed to protect the eyes and face against both the mechanical and thermal hazards produced by an arc flash. This includes intense radiant heat, UV and infrared radiation, pressure waves, and molten metal splatter — the primary injury risks associated with arc flash incidents during live electrical work or proximity to energised parts.

What is NFPA 70E PPE Category 2 and what does it mean for the PS93? NFPA 70E is the US standard for electrical safety in the workplace, which classifies arc flash PPE into four categories based on the incident energy level a garment or product can withstand. PPE Category 2 corresponds to a minimum arc rating of 8 cal/cm². The PS93 exceeds this with an ATPV rating of 14 cal/cm² under ASTM F2178, making it compliant for Category 2 arc flash work tasks as defined by NFPA 70E.

Which helmets is the PS93 arc flash visor compatible with? The PS93 carrier is compatible with Portwest Endurance (PS53) and Height Endurance (PS54) helmets, fitting standard 30mm helmet slots. It must be used exclusively with non-vented, Category III helmets to maintain arc flash protection integrity.

What is the ATPV rating of the PS93 visor? The PS93 carries an Arc Thermal Performance Value (ATPV) of 14 cal/cm² tested to ASTM F2178, indicating the level of incident energy the visor can absorb before there is a 50% probability of causing a burn injury. This rating qualifies it for use in NFPA 70E PPE Category 2 tasks.

Why is a flip-up carrier important for arc flash visors? A flip-up carrier allows workers to raise the visor between tasks without removing their helmet, maintaining head protection at all times and reducing the risk of the visor being set aside and unavailable when needed. The PS93's balanced carrier design distributes the visor's weight evenly, reducing strain during prolonged wear on live working jobs.

What is the difference between Class 1 and Class 2 arc flash visors? Arc flash visor classes relate to the level of arc flash protection provided, typically corresponding to the incident energy rating. Class 2 visors such as the PS93 offer a higher level of arc flash protection than Class 1 products, making them appropriate for higher-risk live working scenarios, greater incident energy exposures, and tasks classified under NFPA 70E PPE Category 2.
