What are the layer effects of the Environmental tab

Ah cool, this is a really important question! The Environmental 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 (see this 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. Environmental 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 Environmental tab is included in the PTW, it will become visible automatically in Section 15 of the Approve tab:

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

3/. Active effect - Environmental Hand-back section (Chemical): When specific hazard aspects are checked as YES in the Work Environment section of the Environmental tab, hand-back checks, specific to those hazard aspects, will be displayed in the environmental hand-back section, in section 16 of the Approve tab. In this case, when the specific hazard aspects are chemical, the following active layer 1 mechanism operates:

4/. Active - Environmental Hand-back section (Fluorescent): When specific hazard aspects are checked as YES in the Work Environment section of the Environmental tab, hand-back checks, specific to those hazard aspects, will be displayed in the environmental hand-back section, in section 16 of the Approve tab. In this case, when the specific hazard aspects involve fluorescent tubes or bulbs, the following active layer 1 mechanism operates:

5/. Active - Environmental Hand-back section (Heavy Metals): When specific hazard aspects are checked as YES in the Work Environment section of the Environmental tab, hand-back checks, specific to those hazard aspects, will be displayed in the environmental hand-back section, in section 16 of the Approve tab. In this case, when the specific hazard aspects involve heavy metals, the following active layer 1 mechanism operates:

6/. Active - Environmental Hand-back section (Building Waste): When specific hazard aspects are checked as YES in the Work Environment section of the Environmental tab, hand-back checks, specific to those hazard aspects, will be displayed in the environmental hand-back section, in section 16 of the Approve tab. In this case, when the specific hazard aspects involves the generation of building waste, the following active layer 1 mechanism operates:

7/. Active - Infrastructure Hand-back section (Fire System): When specific client infrastructure aspects are checked as YES in the Work Environment section of the Environmental tab, hand-back checks, specific to those hazard aspects, will be displayed in the infrastructure hand-back section, in section 16 of the Approve tab. In this case, when the infrastructure aspect involves the possibility of work on or near any of the fire system, the following active layer 1 mechanism operates:

8/. Active - Infrastructure Hand-back section (Security System): When specific client infrastructure aspects are checked as YES in the Work Environment section of the Environmental tab, hand-back checks, specific to those hazard aspects, will be displayed in the infrastructure hand-back section, in section 16 of the Approve tab. In this case, when the infrastructure aspect involves the possibility of work on or near any of the security system, the following active layer 1 mechanism operates:

9/. Active - Infrastructure Hand-back section (Network System): When specific client infrastructure aspects are checked as YES in the Work Environment section of the Environmental tab, hand-back checks, specific to those hazard aspects, will be displayed in the infrastructure hand-back section, in section 16 of the Approve tab. In this case, when the infrastructure aspect involves the possibility of work on or near any of the networking system, the following active layer 1 mechanism operates:
