Temporary gates, fencing and work zones can shift as a project progresses. Security instructions and access controls should change with them.
At a glance
- Construction access and egress must comply with applicable OHSA requirements.
- Security personnel should know current ordinary access points, vehicle routes and authorized entrances.
- Property notice and access rules should be reviewed when temporary entrances are created.
What this means in practice
The official rules establish a baseline, but a workable security assignment still needs property-specific decisions. The client and provider should turn general requirements into clear instructions about what is checked, who can authorize exceptions, what must be documented and when another authority takes over.
Questions to confirm
- Which entrance is active today?
- Are old gates still accessible?
- Have signs, lighting and guard instructions been updated?
Picture this at your property
A crane delivery requires a temporary opening in the perimeter fence. The gate remains in place overnight, so the site should update security instructions before the next shift.
The value of the example is the decision process: identify what is known, what remains uncertain, who has authority, and what information should be preserved for follow-up.
Practical takeaway
The strongest security process is usually the one that makes responsibilities, observations and escalation clear. That creates a service that can be understood and reviewed without overstating what security can guarantee.
