Regulation 20 Security levels
Where the Secretary of State gives a Port Security Authority notice of the security level that is to apply to a port or part of a port, the Port Security Authority must ensure that the security measures required for that level and set out in the port security plan are in place at that port or that part of a port—
within such time as is specified in the notice; or
if no time is specified in the notice, within 24 hours of that notice being given.
The three security levels are—
security level 1;
security level 2; and
security level 3.
In this regulation—
“security level 1” means the level for which minimum appropriate protective security measures are to be maintained at all times;
“security level 2” means the level for which appropriate additional protective security measures are to be maintained for a period of time as a result of a heightened risk of a security incident;
“security level 3” means the level for which further specific protective security measures are to be maintained for a limited period of time when a security incident is probable or imminent, even if it is not possible to identify the specific target.
