Description
The Portwest BIZ6 flame-resistant overall is a one-piece protective garment with an integrated hood, designed for welders and technicians working in environments with risks of open flames, radiant heat, and electric arcs. The garment is made of 100% cotton (330 g/m²) and offers certified protection according to several international standards, including EN ISO 11612 and EN ISO 11611.
For what work is the Portwest BIZ6 flame-resistant overall suitable?
The BIZ6 is suitable for welders, electrical technicians, and industrial workers exposed to flames, molten metal splashes, and the thermal hazards of an electric arc.
Thanks to the certification according to EN ISO 11611 Class 1 (A1+A2), the overall meets the requirements for welding work where splashes and drops occur. The EN ISO 11612 certification (A1+A2 B1 C1 E2 F1) covers protection against radiant heat and convective heat. The integrated hood provides extra coverage for the head and neck, which distinguishes the overall from a standard flame-resistant overall without a hood.
What does the ATPV value of 11.2 cal/cm² on the BIZ6 overall mean and when do you choose this model?
The ATPV value (Arc Thermal Performance Value) of 11.2 cal/cm² indicates how much thermal energy the material can absorb before there is a 50% chance of a second-degree burn. The higher this value, the more protection the garment offers against an electric arc.
The BIZ6 is certified according to ASTM F1959/F1959M-12 with an ATPV of 11.2 cal/cm² and a HAF of 80.4%, and also complies with EN 61482-1-1 with an ELIM of 8.3 cal/cm². This model is a suitable choice for work environments with a moderate arc risk where head protection is also required.
The overall can be washed at a maximum of 40°C and can be ironed at a maximum of 150°C; tumble drying is not allowed.
