Events and exhibitions present unique electrical safety challenges. Equipment comes from multiple sources — exhibitors, hire companies, the venue, and the event organiser itself. There's often significant time pressure during setup, and the temporary nature of the installation means there's no permanent maintenance history for the equipment in use.
Who is Responsible for PAT Testing at Events?
Responsibility for PAT testing at events is shared. Event organisers are typically responsible for equipment they own or hire for the event. Exhibitors are responsible for the equipment they bring to their stands. Equipment hire companies should ensure all hire equipment is tested before delivery. Venues may require evidence of testing from all parties as a condition of use.
What Equipment Needs Testing at Events?
- Audio-visual and stage lighting equipment
- Catering equipment (kettles, coffee machines, fridges)
- Display screens and promotional equipment
- Exhibitor stand equipment (computers, monitors, demo devices)
- Power tools used during event build and breakdown
- Extension leads and power distribution boards
- Temporary lighting rigs
Temporary Event Structures
For outdoor events using temporary structures (marquees, tents, stages), all electrical equipment should be PAT tested before the event. Outdoor events face additional risks from weather, ground conditions, and the temporary nature of power supplies. Equipment used at outdoor events should be rated for outdoor use and tested more frequently than equivalent indoor equipment.
Getting Your Event PAT Tested
For upcoming events in Essex and the South East, MES PAT Testing Ltd can arrange pre-event testing of your equipment inventory. We can also attend during event build to test hire equipment as it arrives on site. Contact us well in advance to discuss the scope, timing, and logistics of event PAT testing.
