06 / ARC FLASH & INSULATION
Arc-rated clothing, face shields and complete ensembles
Arc-rated PPE should be specified by the arc rating of the complete required protection system, not by appearance, fabric weight or a generic “FR” label. A flame-resistant garment may be useful for other thermal hazards yet still be unsuitable for a particular arc-flash exposure if it lacks the required arc rating / test evidence.
Garment rating
Specify the minimum cal/cm² or other project-defined arc-protection requirement tied to the approved assessment / method.
Face / head protection
Standard clear face shields are not automatically arc-rated. Verify the specific arc rating and test standard.
Layering
Any layered system should be evaluated as an approved combination rather than adding garment ratings mathematically.
Sizing & movement
Fit affects whether the worker can wear the ensemble correctly; include actual garment and glove sizes in the RFQ.
Insulating gloves, matting and voltage-rated equipment
Insulating PPE is selected against a voltage class and test regime. For example, Haisar's NOVAX Class 0 listing states an AC maximum use voltage of 1,000 V, while its Class 2 listing states 17,000 V AC. Those class values should not be treated as a licence to work energised; they are equipment specifications that must sit inside the approved electrical work procedure and competent-person controls.
For the detailed glove-class ordering table, use Haisar's Insulating Gloves Class Guide. This page stays broader so the two articles do not compete for the same query.
