What must a security guard do when taking over a post?

Short answer

Report to the post before the shift starts, in uniform and with the equipment that post requires.
Take over the post through a handover report, signed together with the guard going off shift.
Check the post's equipment, radios and goods against the inventory list.
Read the post's specific standing orders and the events logged during the previous shift.
Confirm the handover to dispatch and report any missing item or fault on the spot.

Law 333/2003, art. 46 — while on duty a guard must know the vulnerable points inside the site (a), guard the goods listed in the security plan (b) and follow the post's standing orders (q).
Law 333/2003, art. 46 (e) — any event during the shift must be reported immediately to the direct supervisor and to the guarded company's management.
Law 333/2003 (Art. 46 q) and Government Decision 301/2012 (Art. 33) speak of the “general and particular post orders”, but they define neither term and give no model. The post orders are one of the elements set by the security plan, and the shift or site supervisor briefs the guards on them.
Government Decision 301/2012, the methodological norms for Law 333/2003 — the model “Register of service handover reports” is Annex 2b) and is kept at the post.

Example: at a warehouse guarded 07:00–19:00, the incoming guard arrives at 06:45, signs the handover report, checks the two radios and the flashlight against the inventory, reads in the register that a camera on the north side was faulty during the previous shift, and reports to dispatch that the fault is still there.
Illustrative example: the security plan provides for an access post that deliveries are accepted only between 08:00 and 16:00; the guard starting the night shift reads the provision at handover, turns away a delivery arriving at 22:00 and logs the event.

The post is handed over verbally, with no signed report — after an incident nobody can tell which shift it started in.
The security plan and the post's standing orders changed weeks ago, but the printed copy at the post is still the old one.
Faults spotted at handover are mentioned verbally and lost, instead of being logged and escalated.
The handover register exists only on paper, at the post, so the manager learns nothing until the next site visit.

The dispatch board shows the shifts running now, the guards checked in at the post, those who are late and the posts with no named guard. Check-in and check-out are recorded from the panel.
In the dispatch event journal, the text of an entry is never edited and a follow-up is recorded as a “resolution”, so whoever takes over can read what happened before. Admins, managers and owners can delete entries, so the journal does not replace the official register.
From the Pro plan, equipment issued to a guard is recorded as a handover confirmed with name, date and time, and its return is recorded the same way; the list of equipment with a service due is opened from the panel.
Incidents are kept with category, severity, description and escalation status, and an incident can be closed or reopened. The post's standing orders and the handover register stay the official documents of the company; 4guards does not replace them.
