IEC 60079-17 - continuous supervision

IEC 60079-17 - continuous supervision

IEC 60079-17 - continuous supervision

(OP)
In the standard for Inspection and maintenance of electrical installations in hazardous areas, what is meant by 'continuous supervision' and in what instance would it apply?

RE: IEC 60079-17 - continuous supervision

I'm not sure what clause you are speaking of. Normally it means that if a hazardous condition could exist the operation must remain under continuous supervision so that an accident should not occur, protection of a danger zone. You may be require to lock out a control panel if not under continuous supervision if another person could accidentally create a hazardous motion. An example is a pluggable device, the plug acts as the disconnect device. When the plug is disconnected it must be within site of the operator/maintenance/service person at all times (continuos supervision) so that no one will plug it in without his/her knowledge.
