Box A ACTION FROM LOCAL COORDINATOR

Local coordinator should activate any local incident plan and urgently establish and brief teams on:

Extent of failure.

Likely duration of failure.

Interruption to other services (e.g. oxygen, water).

Box B SOURCES OF ADDITIONAL LIGHT

Open doors and blinds.

Hand torches, portable lights, mobile phones, laryngoscopes.

Box C TYPES OF POWER SUPPLY

Standard power socket: not protected.

SPS: Secondary supply (red socket) for devices that can sustain brief periods of loss of power (e.g. those with internal battery back-up).

UPS: Uninterrupted supply (blue socket) for instantaneous and continuous protection. This supply is limited therefore avoid using UPS sockets unless absolutely necessary.

Devices' internal battery backup: this may not supply all functions of the device and duration may be variable.

Box D CRITICAL CHANGES

Mains oxygen failure → 4-1

Emergency evacuation → 4-3
