The layer effects of the Hot Work tab

Oh yes, this is a really important question! The Hot Work tab has both layer 1 and layer 2 effects in its workings. The layer 2 effects have been explained in detail in the Precautionary Measures question (refer to this section for more details), so we'll concentrate on the layer 1 effects:

The layer 1 effects from this tab are connected to the Approve tab and are both passive and active. Height work details are reflected in both the contractor declaration section (section 15) and the site hand-back section (section 16): 

1/. Passive effect - Approval section: When the Hot Work tab is included in the PTW, it will become visible automatically in Section 15 of the Approve tab:

2/. Passive - Hot Work Permit: Hand-back section: When the Hot Work tab is included in the PTW, it will have a specific check which will automatically be displayed in the Site Hand-back section of Section 16 of the Approve tab:

3/. Active - Hot Work Permit: Hand-back section (Vessel/Tank): When specific hazard aspects are checked as YES in the Work Environment section, hand-back checks, specific to those hazard aspects, will be displayed in the hot work hand-back section, in section 16 of the Approve tab. In this case, when the specific hazard aspects involve hot work on vessels or tanks with known flammable or unknown contents, the following active layer 1 mechanism operates:

4/. Active - Hot Work Permit: Hand-back section (Piping): When specific hazard aspects are checked as YES in the Work Environment section, hand-back checks, specific to those hazard aspects, will be displayed in the hot work hand-back section, in section 16 of the Approve tab. In this case, when the specific hazard aspects involve hot work on piping with known flammable or unknown contents, the following active layer 1 mechanism operates:
