Description
The flame-resistant overall is designed for professionals working in environments with fire, flash, and explosion hazards. The Portwest BIZ7 combines flame-resistant protection with class 3 high visibility and antistatic properties, making it suitable for use in ATEX zones and other hazardous industrial environments. The outer material consists of 99% cotton and 1% carbon fiber, with a weight of 330 g/m².
For which sectors and working conditions is the Portwest BIZ7 flame-resistant overall suitable?
The BIZ7 is suitable for sectors such as petrochemicals, energy, offshore, metalworking, and other industries where there is a simultaneous risk of flame, heat, and ignition of explosive atmospheres.
Thanks to its multi-standard certification, this overall covers multiple hazards at once. The antistatic properties prevent electrostatic discharge in ATEX zones, while the class 3 high visibility makes the wearer clearly visible in environments with moving traffic or machinery. This makes the overall suitable for complex work situations where multiple risks converge.
What do the standard classes on the Portwest BIZ7 overall mean, and when should you choose this model?
The BIZ7 is certified according to EN ISO 11612 (A1+A2 B1 C1 E3 F1) for protection against heat and flame, EN ISO 11611 Class 1 (A1+A2) for welding work, EN ISO 20471 Class 3 for maximum visibility, and EN 1149-5 for antistatic performance.
Choose this model when your work environment combines several of these risks and you do not want to work with separate layers of clothing. Unlike a standard flame-resistant overall, the BIZ7 offers a comprehensive solution in a single garment thanks to its multi-standard certification, which is practical and reduces the risk of incorrect combinations of protective equipment.
The overall can be washed at a maximum of 40°C on a mild cycle; do not bleach, do not tumble dry, and iron at a maximum of 150°C.
