These are as follows:
Activities are also differentiated by colour, with generic process in grey, strategic processes in burgundy and contractor in dark green. Some processes impact on HSE activities but are not within the remit of the HSE MS.  Where these are complied with, but are not HSE documents, these are in yellow.
Many activities require informed decision making to enable their completion. These are represented by a orange diamond, and indicate what is required if an answer is “Yes” or “No”.

All support information is represented graphically, depending on the type of information represented. If the action requires the use of a checklist, the below symbol is used, and by clicking on it, the user will be presented with a checklist that is specific to the activity.

1.      Select the page to be printed and then either right click on it, or select Ctrl + P to bring up the print instruction

2.      Check settings and print the page.

3.      The printed page (hard copies) of the processes MUST then be validated by handwriting the date of the print onto each page. (WITHOUT A DATE  documents are considered UNCONTROLLED and are thus INVALID.

4.      If the process selected for printing has any referencepopups on it, such as  Notes, Templates, Legal reminders, checklists, etc.  each of the associated popups MUST be printed and attached to the process document. See example below.
This example is a process for selecting an investigation team, which has 4 popups’. The popups have information related to doing the activity in them. In general use they remain hidden, but if the information is required, by selecting them, the information becomes visible. So, if popup 1 is selected, it displays this  associated information.
To properly print this process, the final hardcopy would consist of the printing the process plus popup1, popup 2, popup 3 and popup 4.This equates to a total of 5 printed pages, all of which together form the process.
