Incendiary bombs

Terrorists have often used incendiary bombs to attack economic targets. These are generally hand-carried devices, often deployed against targets such as retail outlets and transportation. The usual intention is to cause economic damage and weaken public confidence rather than cause mass casualties.

When planning protective measures, remember that incendiaries are generally small, that they ignite rather than explode (often when the target premises are empty) and that there is usually more than one device.

The attacker will regard the attack as a success even if they do no more than trigger the sprinkler system, which itself can damage stock or furnishings. Incendiary devices are fairly simple to make and do not require access to explosives.

What you can do

• make security measures part of your normal anti-crime precautions, along with regular checks on fire extinguishers, sprinklers, smoke alarms and fire blankets.
• conduct discreet searches during business hours at times of high risk or after a close down period e.g. Christmas. Staff should be trained in what to look for, but do not need a high degree of knowledge since most devices are not elaborately concealed; the terrorist needs to find easily accessible hiding places.
• since anyone finding a suspect device will probably be unable to tell whether it is incendiary or explosive, brief them to clear the surrounding area and call the police. If a device ignites, it may be sensible to make an immediate and brief attempt to extinguish it - provided normal fire arrangements and staff training are adequate. Remember, however, that there may be a number of devices and be prepared to evacuate the building according to pre-arranged plans.
