Emergency lighting installations must be inspected at least once a year and is intended to determine whether the system meets all requirements. The inspection includes an assessment of the technical condition of the installation, but just as important is the determination that the system is geared to the actual use of the building. The inspection is a baseline measurement prior to the periodic maintenance, which guarantees that the system will function properly again for at least one year. ISSO Publication 79 serves as a guideline for the inspection and maintenance of an emergency lighting installation. This guideline meets the requirements of the Building Decree and the Working Conditions Act.
When all preparations have been made and agreements have been made with the client, the actual inspection can begin. The following documents are required for this:
• Current scale drawings of the building in which the emergency lighting is projected
• Evacuation drawings – to determine what the escape routes are
• Reports of previous inspections
• Log of the performed maintenance
• Reports of risk inventories and evaluations with regard to high-risk workplaces and / or emergency lighting
• Any other documents
The starting point for the periodic maintenance is consultation of the most recent inspection report and the logbook containing the description of the activities of the previous maintenance visit. The logbook should also contain the most recent drawings of the installation. There may be any outstanding issues or recommendations that need to be addressed during maintenance. If no logbook is available, it is sensible to advise the client to inspect the system first. If this is not feasible, the available documentation is the starting point. It is very important that all activities are systematically carried out and documented.
If not all necessary documents are available, this should be stated first in the inspection report. It is also important to indicate how much influence the absence of certain documents has had on the inspection, for example in the identification of risky workplaces. Insofar as statements or conclusions on this point are based on personal experience and expertise, this must be reflected as such in the report.
The first impression of a system is often telling. As a rule, it is easy to see whether an installation has been properly maintained or whether maintenance has been overdue. Separately, six questions are answered during the inspection:
• Does the emergency lighting system still fit with the use of the building?
• Has specific risky situations been sufficiently taken into account?
• Are the products used satisfactory?
• Has the emergency lighting been installed correctly?
• Is the required light level being achieved?
• Do the luminaires achieve the required burning time in an emergency?
