I am dealing with a fire risk assessment in effectively a large lock & leave council garage where a small number (<10) meals on wheels vans are stored. No staff, low risk and a very tidy place of work. They have a single non maintained emergency lighting unit which, I believe must be kept as it's a windowless building. BS5266 recommends monthly checks and annual tests. With such a low risk and with the garage only occupied 15 to 25 minutes a day, I am minded to suggest that the RP tests the EL annually only and dumps the monthly checks. Of course, this is a variation of the BS, but if the reasons for the variation were recorded on the FRA, would this be suitable? Don't forget that this is a low risk premises which is empty of vehicles for 14 hours a day and empty of staff 23.5 hours a day. Any views???
