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.
If it is not possible to deactivate the security feature, it may be necessary to make a forcible entry. 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.
For further information about forcible entry see National Operational Guidance: Fires and firefighting.
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 specifically 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 will be carried out under escort and in accordance with pre-determined arrangements.
