Notes:
1. If not practical (eg if work is carried out in multiple locations) the Performing Authority may keep the PTW.
2. If Permit Issuers do not have easy access to control rooms, they may require an additional personal copy.
3. For example, if a site has separate PTW forms for hot work and work at height, then a welding job carried out from a mobile scaffold would require two PTWs to be issued.
