Temporary electronic installations and electricity supply interruptions

Temporary electronic installations are often necessary in public events. Temporary electronic installations cause a risk of fire and accidents during the events. Due to this, the event organiser must take electronic safety into account already during the planning stages.

With regard to electricity, the following factors should be taken into account:

  • Qualified people and companies have carried out the electronic installations.
  • Any cables on passage ways and emergency exits have been protected, for example with floor cable covers, rubber rugs or by digging them into the ground or by lifting them up.
  • Electrical and other wiring must not interfere or endanger walking or cycling traffic outside the event area. Reflective material and warning traffic signs must be used in cabling.
  • In outdoor premises, only electronic cables intended for outdoor are used.
  • Electrical equipment used outdoors are protective earthed, insulated or operated with protective voltage. In dry outdoor conditions, protective earthed or insulated devices for indoor use can also be used temporarily. In these situations, the equipment is insulated from the ground and protected from rain and moisture.
  • An installation certificate will be compiled for temporary electronic installations, which is available at the venue.

With regard to aggregates, the following factors should be taken into account:

  • The aggregates have been placed far enough from any buildings, structures, traffic routes and the public area.
  • The safety arrangements defined under the section “Dangerous chemicals during public events” are also applied to aggregates.
  • A first aid fire extinguisher with the effect class of at least 34 A 183 BC and a sufficient amount of absorbent are placed in the vicinity of the aggregates.

With regard to power outages, the following factors should be taken into account:

  • The lighting of the exit routes is also ensured in the event of an interruption, for example with a battery-certified exit route markings, aggregates or flashlights.
  • Megaphones or audio equipment certified by a separate source have been prepared to guide people.
