Hazardous Areas – Fuel Nozzle

The graphics showing the zones around the nozzle when refuelling vehicles have been improved to give a
better representation of the requirements. The classification for the nozzle without stage 2 vapour recovery has
been increased so that the entire area is now zone 1, previously only the bottom 250mm was zone 1.

Hazardous Areas – Composite

The composite views have been updated to show the all above changes, and have been improved to show more
clearly the zones in relation to the vehicle being refuelled.
