MATERIALS HANDLING FOR HAZARDOUS ZONES
Wherever the possibility of explosion exists there is a requirement for safe lifting and electrical equipment. The specification is selected by taking into consideration "the probability of the occurrence of a explosion", this probability being divided into hazardous zones, outlined as follows:
| ZONE 0: | Area in which an explosive gas is present under normal circumstances. |
|---|---|
| ZONE 1: | Area in which an explosive gas could be present under normal circumstances. |
| ZONE 2: | Area in which an explosive gas would not normally be present, or would only be present for short periods. |
Once the danger has been determined it is possible for the user to define the exact and safe equipment to be used, the applicable design regulations being CENELEC (European Commission for Electrotechnical Standardisation), European Norms, DIN EN 50014-50020. Such equipment can be marked as follows:
Explosive gases and vapours are classified in explosive groups and temperature classes according to their explosive energy and ignition characteristics.
| Temperature Class |
T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| Max. Surface Temperature |
450ºC | 300ºC | 200ºC | 135ºC | 100ºC | 85ºC |
