Passively Safe Gantry Risk Model (PSGRM)
IAN 85/07 Design of Passively Safe Portal Signal Gantries
This IAN is a risk based draft standard and does not follow the traditional standard format. It has two parts that must be used together:
- The written Interim Advice Note IAN 85/07 "Design of Passively Safe Portal Signal Gantries" contains some mandatory requirements but gives mainly advice and guidance and the
- "Passively Safe Gantry Risk Model (PSGRM)" which is in Excel and enables the Designer for each site/scheme to establish the appropriateness of this type of gantry as opposed to the more traditional type covered by BD 51 (as revised by IAN 86/07).
This IAN is issued as a draft standard to enable designers to use the document and to provide feedback at all stages of its use, which will eventually inform the issue of a final standard.
Instructions on how to use the model are contained in IAN 85/07 at Appendix B: Passively safe gantry risk model user guide.
