EEMUA Publication 241 - Guidance on the presence and operation of portable self-energised electrical / electronic devices In potentially explosive atmospheres (gas and dust)
|Publication Date:||1 May 2019|
This document aims to provide guidance in relation to the electrical ignition risks within areas with potentially explosive atmospheres. It therefore includes:
− vapours and mists - such as petroleum products;
− gases - such as hydrogen, and
− combustible dusts - such as food products and cement.
The guidance only covers electrical ignition risks from self-energised devices (including those powered by extra-low voltage), and therefore mechanical sources of ignition and devices powered by mains electricity are not covered. However, some of the guidance within this document (such as section 12) may have some useful guidance which can be applied to the use of equipment powered by mains electricity.
The guidance only covers portable devices, and as such does not cover any fixed equipment within the plant (such as lighting), or isolatable equipment which is fixed to vehicles (such as reversing cameras). Therefore, taking a vehicle-mounted hand-held computer as an example, the dock which is mounted in the vehicle cab would not be included within this guidance, but the portable hand-held computer would be included.
The guidance does not cover portable generators.
This document only considers industrial facilities and does not aim to provide guidance on the use of portable self-energised electrical and electronic devices in public areas such as service stations or transportation on public roads.
