hot work processes).
As part of the identifi cation of hazards, it is useful to use
HSE’s RIDDOR ‘accident categories’ as a means of iden-
tifying the hazards by considering the causes of injury
which may arise. These categories cover slips, trips and
fall, falls from height and falling objects, collision with
objects or being trapped or crushed beneath or between
objects, manual handling, contact with machinery or hand
tools, electricity, transport, contact with hazardous chem-
icals, asphyxiation/drowning, contact with animals, and
violence, not to forgetting of course fi re and explosion.
These categories have been adopted when trying
to identify hazards and risks in relation to general health
and safety; however, they may equally be applied when
considering the types of risk in relation to fi re which may
include:
➤
Slips, trips and falls (including those from height)
while evacuating
➤
Handling, lifting or carrying portable fi re fi ghting
equipment
➤
Being trapped by a wall collapsing
➤
Being asphyxiated from the inhalation of smoke
➤
Coming into contact with the release of harmful
substances
➤
Being exposed to fi re or explosion while undertaking
fi re fi ghting action
➤
Coming into contact with live electrical equipment
due to degradation of wiring during a fi re
➤
Coming into contact with moving machinery while
trying to shut down in the event of an emergency
➤
Being struck by a moving vehicle while evacuating
➤
Being assaulted by a person panicking in the event
of a fi re.
It is likely that the above list will not necessarily be
included in a fi re risk assessment (see later in the mod-
ule); however, each should be considered as part of a
general risk assessment.
In the same way, categories of health risk, i.e.
chemical, biological, physical, physiological, must also
be considered as part of a general risk assessment
process. Chemicals can obviously present a risk when
coming into contact with humans, whether or not it is as
a result of fi re, and the release of asbestos fi bres may
also present a signifi cant risk (see Chapter 7).
Many of the physical and potentially psychological
health risks can also be linked to a fi re scenario and thus
must be taken into account during the risk assessment
process.
It is also prudent when assessing hazard and risk
to make the distinction between acute (single instant
contact) and chronic (prolonged/repeated exposure) ill
health. It may be that the inhalation of smoke containing
toxic chemicals will cause death rapidly or that the inhal -
ation or exposure to less hazardous chemicals during the
fi re process may worsen conditions of a person who has
already been exposed over a period of time.
