Explosion Proof Bridge Crane Zoning
Hazardous areas are categorized into zones according to the assessment of the frequency of the occurrence and duration of an explosive atmosphere. A zone is an area in which an explosive gas atmosphere:
- is present continuously or for long periods of time, Zone 0;
- is likely to occur in normal operation, Zone 1;
- is not likely to occur in normal operation and, if it occurs, will only exist for a short time. Zone 2.
Explosion Proof bridge Crane Zoning: Zone 1 & Zone 2 Hazardous Areas.
Application of Explosion proof bridge crane
The proof marks are Exd Ⅱ BT4 and Exd Ⅱ CT4.
Explosion proof bridge crane is applied to sites, where is not higher than the II B or II C-class, and the sites with explosive air mixture formed with inflammable gas (or steam) and air whose factory ignition temperature groups of not less than the T4 group.
