IRP 8 (2016) represents the results of a limited scope review conducted between December 2014 and December 2015. The most significant changes include:

• Review and update of 8.2.2. Fluid Classification (formerly 8.2.4) and the corresponding Appendix B: Guidelines for Classifying Flammable Fluids (formerly Attachment 1: Guidelines for Classifying Flammable Fluids)
• Moved information from Attachment 4 Well Servicing -- Wellhead Rig-In Procedures and Pressure Rating of Wellhead Valves to Section 8.2.5.
• Review and update of 8.4 Pre-Spotting Activities (includied distinguishing between planning functions vs pre-spot safety meeting)
• Added Hot Zone planning and placarding responsibilities to 8.4 Pre-Spotting Activities and removed Attachments 7 and 8 which previously dealt with Hot Zone placarding.
• Reworked 8.9 Fire Protection Requirements. This included moving requirements formerly captured in attachment 13 Fire Training Requirements into the main body, creating a matrix for determining fire protection requirements including fire protection for small volumes, as well as updates on fire fighting training for well service personnel.
