Control measure – Gain access or entry: Sites with security features
Control Measure Knowledge
The fire and rescue service may be able to gain access via codes or keys for sites with security features. The responsible person, or a security company, should be contacted to assist with gaining access.Where possible there should be liaison with the responsible person and a review of risk information to establish if access or egress may be affected by security features.
If it is not possible to deactivate the security feature, it may be necessary to gain access or entry by force (sometimes referred to as forced entry or forcible entry). Before doing so the impact of this entry on any hazards present should be considered.
The type of building construction, possible entry points and the security features present should be assessed. This will assist with selecting the most appropriate equipment and techniques for the situation, which can save time and prevent unnecessary damage.
Having gained access to sites that have security features, it may be necessary to disable security features, or position personnel to ensure access and egress routes are not compromised.
Security smoke (sometimes called security fog or smoke screen) is thermally generated white smoke used as a security measure. Security smoke machines may use glycol or glycerine mixed with distilled water to produce a dense white fog that obscures vision.
Where there are armed guards, fire and rescue service activity should always be carried out under escort and in accordance with pre-determined arrangements.
Personnel should follow any agreed method for maintaining access and egress at sites such as places of lawful detention to prevent becoming isolated. If personnel are not familiar with the security systems, it may be necessary to test overriding security features before gaining access. Methods of maintaining egress may include:
- Keeping doors open by using dead bolts or specialist equipment
- Not allowing lone working
- Posting personnel to manage doors or security features
- Overriding security features
