The hazards are:
An overloaded plug socket,
a full cup close to the extension lead,
the fire door is propped open with a fire extingusiher,
a wet t-shirt drying on the radiator,
a pile of paperwork close to the radiator and the overloaded plug socket,
overflowing waste paper bin,
a barrier across the front of the fire escape door,
a worker spraying aerosol sprays close to items that are at risk of igniting,
the trailing wires across the floor,
and the candles on the window could set the blinds on fire or could be blown or knocked onto the floor causing a fire
