ELECTRICITY AND POWER

Workers in the Electricity and Power industry are at risk of exposure to Electric Arc flashes that can
occur if there is a short circuit, switching fault, operator error or equipment failure. Electric Arcs
can expose workers to very high energy levels and often lead to severe burns and hand / eye injuries.
Wearing the wrong workwear can make injuries worse, so it is important to choose the right protective
clothing that provides arc protection in every layer. It is equally important to choose gloves and face
protection that are certified to protect against Electric Arcs.

RISK ASSESSMENT

• Electric Arc
• Molten Metal splashes
• Radiant heat
• Convective heat
• Electric shock
• Shock waves
• High noise
• Optical radiation
• Toxic gas
• Flame & Heat
• Traffic accidents (working outdoor)

All of Tranemo 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 is also stated and refers
to the Risk Assessment standard NFPA 70E. All new Tranemo products will be tested according to
EN 61482-2 and marked with both the ELIM and ATPV/EBT values.

RISK EVALUATION

When working as an electrician you need garments certified according to EN 61482-2 / IEC 61482-2 in combination with EN ISO 11612 as there may be a risk of an Electric Arc. Electricians working outdoors may also need High Visibility garments certified to EN ISO 20471.

An Electric Arc accident comprises of many varied risks that will affect the PPE clothing in different ways but with the right solution, we can help to minimise the impact of these risks. A Tranemo Skinsafe™ system where the outer layer reaches PPE 2 and has an Arc Rating (ATPV or EBT value according to NFPA 70E) above 8 cal/cm² is recommended.

The switchgear range ‘Switch’ is designed for work where there is a risk of being exposed to Electric Arc with a very high energy level - for example in switchgear environments, when cutting off power or commissioning electrical systems. Garments in the ‘Switch’ range offer protection of 40 cal/cm² (PPE4).
