SIA Door Terrorism Awareness (UK) 3

Question 1

What does 'IED' stand for in a security context?

Accepted Answer

Improvised Explosive Device

Answer

An IED (Improvised Explosive Device) is a homemade bomb; door supervisors should be aware of indicators of IEDs and know not to use radios near suspected devices as radio signals can trigger some detonators.

Question 2

Why should radios NOT be used near a suspected IED?

Accepted Answer

Radio signals can trigger electrically initiated detonators

Answer

Some IEDs use radio-controlled detonators; using a radio or mobile phone near a suspected device could trigger detonation, making it critical to move away before communicating.

Question 3

What is the recommended minimum distance to maintain from a suspicious vehicle?

Accepted Answer

At least 100 metres

Answer

Police guidance recommends at least 100 metres (or more for larger devices) as an initial safety cordon distance from a suspicious vehicle that may contain an explosive device.
