Occupancy profile - vulnerable people risk factors
In cases where Automist is being considered and the individuals occupying the property have a higher-than-
average likelihood of having a fire, or have poor reaction or realisation of the danger presented by fire (or a
combination of both) these vulnerabilities may require enhancements in system resilience, or depending
on the risk, a different solution altogether (such as a PPS).
The following factors are indicators of an occupant’s higher risk from fire:
a)
higher likelihood of fire:
a.
high fire risk habits, such as disposal of smoking materials or leaving cooking unattended;
b)
history of fire-setting behaviour;
a.
history of previous fires or evidence of near misses, such as scorch marks on clothing or
furniture; or
b.
threats of arson;
c)
inability or willingness to escape:
a.
impaired mobility affecting ability to escape;
b.
impaired, due to cognitive ability to react to fire or warning devices;
c.
impaired senses affecting ability to respond to alarm;
d.
poor situational awareness; or
e.
alcohol or drugs, increasing the likelihood of a fire and lowering reaction to alarm.
Improving Automist’s performance and reliability
Additional measures to improve the performance and reliability of the system to address areas of higher
risk should be considered and include but are not limited to any of the following:
1)
increasing the system resilience; and/or
2)
increasing the detection resilience; and/or
3)
increasing the power robustness; and/or
4)
increasing the water robustness; and/or
5)
increasing the sprayhead placement robustness; and/or
6)
increasing the sprayhead density or installing two Automist systems in parallel; and/or
7)
Increasing the frequency of maintenance.
System enhancements should be recorded on the Automist Design Specification (see page 15) and, once
installed, in the commissioning certificate (see page 87).
This DIOM gives guidance on the types of risks and the performance enhancements which are possible, but
deciding whether these are satisfactory is the responsibility of the client (and/or their representatives) in
consultation with all stakeholders and any relevant authority having jurisdiction (AHJs).
Resilience and Robustness
Improving the system’s resilience (the ability of the system to return to a “ready to operate” state) can be
achieved by increasing the frequency and nature of monitoring beyond the minimum annual maintenance
check (see page 94). This is desirable when either the impact of the fire or the probability of fire are high.
