Commercial and industrial premises are generally required to have working emergency and exit lighting, illuminated exit signs and backup lighting that activates during a power failure, so occupants can evacuate safely.
Exit signs must be clearly illuminated and visible, and emergency lighting must activate automatically if mains power fails, providing enough light along escape routes to exit the building safely.
Emergency and exit lighting systems require periodic testing, typically including a routine function test and periodic discharge testing, to confirm batteries and globes are working as intended.
Testing and any necessary repairs should be documented, giving the business a clear compliance record in case of an audit, insurance claim, or incident.
Most commercial and industrial tenancies, offices, retail premises and warehouses included, have some level of emergency lighting obligation. A licensed electrician can assess your premises and set up a testing schedule.
