RISK ASSESSMENT

• Traffic accidents (vehicles in opencast and underground mining)
• Flame & Heat
• Risk of explosion/ATEX-environment (limited)
• Electric Arc (limited)
• Welding sparks (limited)

RISK EVALUATION

When working in a mining environment, garments certified in accordance to EN ISO 20471 are needed to ensure visibility when working around vehicles in an opencast and underground mine. Large vehicles may have large blind spots and therefore High Visibility garments are crucial. Working in an ATEX-environments (such as handling explosives or working in the presence of methane/natural gas in the underground) Tranemo recommends garments certified according to standard EN 1149-5 in combination with EN ISO 11612. The Anti-Static properties of a garment minimise the risk of creating sparks (a source of ignition) which could cause an explosion. The majority of our FR garments are EN 1149-5 certified and have Anti-Static fibres mixed into the fabrics. If a garment has metal details they have to be covered during use according to the EN design requirements.

In mining, most workers are engaged with maintenance and infrastructure work and for electricians, there is also a risk of Electric Arc. With the right solution of clothing marked IEC 61482-2 / EN 61482-2, the impact of these risks will be minimised. A Tranemo Skinsafe™ system with an outer layer that complies with PPE 2 and has an Arc Rating (ATPV or EBT value, according to NFPA 70E) above 8 cal/cm² is recommended.

All our Electric Arc garments have the Arc Rating value stated on the outside FR label to make it easy for you to choose the right protection. In the revised standard, EN 61482-2, ELIM is used as the Arc Rating value. As additional information the ATPV/EBT value can also be stated and refers to the Risk Assessment standard NFPA 70E. All new products will be tested according to EN 61482-2 and marked with both the ELIM and ATPV/EBT values. During the transition period, Tranemo will update new stock garments certified according to IEC 61482-2, meaning garments may therefore have both markings.

For occasional welding, the fabric also needs to pass EN ISO 11611 or use welding accessories to offer further protection.
