ANNEX II U.K. ESSENTIAL HEALTH AND SAFETY REQUIREMENTS RELATING TO THE DESIGN AND CONSTRUCTION OF EQUIPMENT AND PROTECTIVE SYSTEMS INTENDED FOR USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES

2. Supplementary requirements in respect of equipment U.K.

2.2. Requirements applicable to equipment category 2 of equipment-group II U.K.

2.2.1. Explosive atmospheres caused by gases, vapours or mists U.K.

2.2.1.1. Equipment must be so designed and constructed as to prevent ignition sources arising, even in the event of frequently occurring disturbances or equipment operating faults, which normally have to be taken into account. U.K.

2.2.1.2. Equipment parts must be so designed and constructed that their stated surface temperatures are not exceeded, even in the case of risks arising from abnormal situations anticipated by the manufacturer. U.K.

2.2.1.3. Equipment must be so designed that the opening of equipment parts which might be sources of ignition is possible only under non-active conditions or via appropriate interlocking systems. Where it is not possible to render equipment non-active, the manufacturer must affix a warning label to the opening part of the equipment. U.K.

2.2.2. Explosive atmospheres caused by air/dust mixtures U.K.

2.2.2.1. Equipment must be designed and constructed so that ignition of air/dust mixtures is prevented, even in the event of frequently occurring disturbances or equipment operating faults which normally have to be taken into account. U.K.

2.2.2.2. With regard to surface temperatures, requirement 2.1.2.3 applies. U.K.

2.2.2.3. With regard to protection against dust, requirement 2.1.2.2 applies. U.K.

2.2.2.4. With regard to the safe opening of equipment parts, requirement 2.2.1.3 applies. U.K.
