Emergency Lighting in Toilet Cubicles
Summary
1. If the toilet has borrowed light and is less than 8m square:
a. There is no need for emergency lighting, however,
b. If there is a cubicle with full height door – therefore closed without borrowed lighting – then the EM lighting would be required in that cubicle.
2. If the overall toilet has no borrowed light,
a. And the WC cubicles do not have full-size doors; there should be at least one emergency outside row of cubicles.
b. If there is a cubicle with full height door – therefore closed without borrowed lighting – then the EM lighting would be required in that cubicle.
