Electrical High Voltage Focus

Gloves are for Life, not just for Christmas

Working with electricity carries the risk of electric shock – painful and possibly deadly.

Among the more unusual items we have tested here at AMECaL are protective gloves. The effect of having an electricity current flow through your body differs from person to person but it’s clearly undesirable. From a slight tingle in your skin with a low current to pain at higher current, leading up to muscle spasms as the current grows above 20mA, electricity and the human body do not go together well.

Working with a supply disconnected, isolated or earthed reduces the risk but the ultimate insurance against personal harm is protective equipment like gloves. As with most safety equipment, these need to be tested and approved for use, so users can be sure of the level of protection they’re receiving.
