Security Assignment Instructions: What to Include, planned around the premises.
Assignment instructions translate the client's security requirement into the practical actions guards follow on site. They should be specific, current, accessible and approved, without leaving important authority or escalation decisions to individual interpretation.
For contract managers, facilities teams and security supervisors preparing or reviewing guarding instructions.
Every enquiry starts with the actual building or site. We review the reason for cover, the duties required, proposed staffing, operating hours and the instructions that personnel will need to follow. This avoids treating a temporary fire safety or security assignment as a generic guard booking.
When this service may be considered
A new guarding contract is starting
Instructions are generic or outdated
Several shifts apply duties differently
Site risks or access have changed
These examples are not a substitute for competent assessment. The responsible person and their appointed professionals remain responsible for determining the appropriate fire safety, evacuation or security arrangements for the premises.
Define the site, purpose and authority
Instructions should identify the premises, operating hours, contacts, objectives and current risks. Describe each post, patrol zone and required staffing. State who can authorise visitors, contractors, deliveries, keys, searches, exclusions or changes to the service.
Include site hazards, welfare, lone-working arrangements and restricted areas. Security instructions complement, but do not replace, wider emergency, health and safety or construction plans. References should point personnel to the current approved documents.
Set duties, responses and reporting
Specify access checks, patrol routes, monitoring tasks, equipment, incident categories and escalation. Emergency sections should address fire, medical events, intrusion, violence, alarm activation, utilities and emergency-services attendance as relevant. Personnel need clear limits and safe withdrawal routes.
Define daily logs, visitor and vehicle records, patrol evidence, incident forms and handovers. State who receives routine reports and who must be contacted immediately. Personal data should be limited and handled through approved systems.
Control versions and understanding
Every set of instructions needs an owner, approval, issue date and version. Withdraw obsolete copies after changes. Temporary notices should not remain indefinitely or contradict the main instructions.
Induction should confirm understanding rather than collect a signature alone. Supervisors can test key scenarios and inspect delivery. Review instructions after incidents, building changes or client decisions so the written role remains aligned with the actual site.
