The difference between an orderly evacuation and chaos is determined long before the event — in the planning, the drilling and the ongoing checks. In the years I have managed buildings, I have seen again and again that an excellent evacuation plan on paper can dissolve the moment someone opens a door and discovers the route is blocked with boxes. This article is a practical guide — not a theoretical one — to building a system that works.
The Regulatory Framework — What the Law Requires
An office building in Israel is subject to fire-safety requirements derived from several sources: the Business Licensing Law, 1968 and its regulations; the requirements of the Fire and Rescue Authority of Israel, which grants or refuses to approve the safety permit; and Israeli Standard 1220 concerning fire-detection and alarm systems. In addition, the Occupational Safety Ordinance imposes on the employer an obligation to see to emergency procedures and employee competence.
In practice: once a building has an active business permit, the Fire and Rescue Authority can carry out an inspection — and if the PA system is not sound, the record can affect the renewal of the license. This is not a theoretical scenario; it happens.
The Emergency PA System — What Is Mandatory and What Happens in Practice
The PA system broadcasts messages and instructions during an emergency to all areas of the building. The minimum obligations:
- Full coverage: the PA must be heard clearly in all spaces — including stairwells, an underground parking garage, restrooms, and storage areas. These are exactly the places that are forgotten in the first check.
- Volume and intelligibility: hearing noise is not enough — people must understand the instruction. In the multilingual buildings I manage, we introduced a message in two languages (Hebrew and Russian).
- Electrical backup: the system must work during a power failure — usually by means of backup batteries (UPS). The backup test is required separately, not just testing the main mains.
- Annual functional test: at least once a year, performed by a qualified party and documented in a signed protocol.
A mistake I often see: the test is performed only from the control room — not actually walking through all the floors with a sound-level meter. When I did such a walkthrough for the first time in a building I took over to manage, I discovered two "quiet spots" in the parking garage that the PA did not reach at all.
The Evacuation Plan — the Mandatory Components
An evacuation plan is not a PDF file that is printed and forgotten. It is a living document that is updated after every drill, every physical change in the building, and every change in the composition of employees.
- Marked escape routes: two independent exit routes as far as possible for every area of the building — not dependent on one another (not both passing through the same stairway).
- Illuminated exit signage: visible even in darkness and smoke, positioned at a relatively low height because smoke rises upward.
- Assembly points: outside the building, precisely defined (not "at the front plaza" — but "next to power pole number X"), known to all employees.
- Written and approved procedures: who does what, the order of evacuation by floors, a procedure for people with disabilities.
- Defined role-holders: safety wardens on every floor or area, with a defined substitute.
- Attendance list: a way to confirm that everyone has been evacuated — especially critical in buildings with floors leased to different companies.
Role-Holders — Who Is Responsible in an Emergency and What That Means in Practice
An evacuation plan without people who know how to implement it is only paper. My experience teaches that this is the most common point of failure — not a technical failure but a human-organizational one.
The required role-holders:
- Floor safety warden: responsible for evacuating his floor, confirming no one is left behind, and reporting to the command station. Must appoint a substitute when he is absent.
- PA officer: operates the messages in the control room and coordinates with the control room.
- Officer for people with disabilities: leads to the protected waiting areas (refuge areas) and coordinates with the emergency forces.
- Liaison with rescue forces: receives the firefighters and hands them the building map and information on people who may be trapped.
Important: when there is high employee turnover — common in buildings with hi-tech companies — the list of role-holders becomes outdated quickly. I set myself a rule: at the start of every year, and at every significant organizational change, the list is updated.
Safe Evacuation of Special Populations — Don't Leave It to Improvisation
This is the topic most neglected in evacuation plans — and sometimes it entails serious legal liability.
- People with mobility disabilities: in every building I manage, I identify them in advance and define for them a protected waiting area (Refuge Area) — a space protected from fire and smoke, usually in the corridor of the stairwell, with a means of communication with the control room. The elevator is not available in a fire.
- Visitors and guests: they are not familiar with the building. Clear signage is essential for them, and it is important that the floor warden knows how to locate people who are not familiar to him as well.
- Night workers and minimal shifts: when there are fewer people in the building, there are sometimes also fewer safety wardens. The night procedure must be adapted — not a copy of the operating-hours procedure.
- Suppliers and subcontractors: they work in the technical areas, sometimes in the parking garage or on the roof. You need to make sure they too are covered by the plan.
Exit Signage and Emergency Lighting — the Quiet Infrastructure That Is Forgotten
Even the most excellent evacuation plan relies on physical infrastructure that works in the dark and in smoke. Two failures I see again and again in inspections:
- Exit signs that have gone out: in an ordinary check with full lighting — everything looks fine. The problem is revealed only when the lights are turned off. That is why part of the check must be carried out in artificial darkness.
- Emergency lighting with a dead battery: the lamp is lit on the mains, but when disconnected from it — nothing. A real test is disconnecting the mains and checking automatic ignition.
Illuminated exit signage must be visible along the entire escape route, positioned at a height that allows visibility even beneath the smoke layer. The emergency lighting must ignite automatically and light the route for a period sufficient for full evacuation — the accepted requirement is at least an hour, but in tall buildings more may be required.
These are systems that require an independent periodic check — separate from the PA-system test. Combining the two into one round saves time and ensures you don't "botch" one because of the other.
Annual Evacuation Drill — What Works and What Doesn't
An annual drill is the minimum. But the quality of the drill matters no less than the frequency. A "paper" drill — in which employees read the procedure in the conference room — reveals nothing. A real drill requires physically leaving the building.
What a good drill reveals:
- An emergency door that was locked "temporarily" — and has not been opened since
- An escape route blocked with equipment, boxes, or discarded furniture items
- An area where the PA is not heard — because gypsum walls were added since the installation
- A safety warden who did not know he was a safety warden (because the list was not updated)
- Confusion at the assembly point — where one company was given different instructions from another company on the same floor
What happens after the drill:
Every drill ends with a lessons-learned meeting and a findings document that details: what worked, what failed, what must be fixed and by when. Updating the plan after the drill is mandatory — not optional. This is how the plan actually improves from year to year.

Integration with the Fire Detection System
The PA system and the evacuation plan do not operate in a vacuum — they are part of an automation chain that includes:
- Fire detection → PA: a smoke detector that identifies an event should automatically activate the PA for that area (and sometimes for the entire building).
- Fire detection → elevators: the elevators return to the entrance floor and open — and stop serving passengers.
- Fire detection → smoke evacuation: smoke-evacuation fans in stairwells turn on to keep the escape route clear.
The problem: in separate tests each system passes — but the integration chain is not tested. I saw a building where the detector operated, the PA operated, but the elevators did not return to the ground floor because there was a disconnection in the interface connection. Such a chain must be tested as a whole — not as separate systems. This test is part of the requirements for renewing the Fire and Rescue Authority's service approval under the fire safety law.
Frequently asked questions
How often is an emergency PA system in an office building tested?
At least once a year, including testing the volume and intelligibility of the message in all spaces (including stairwells and parking garage) and electrical backup during a mains failure. The test must be documented in a signed protocol. Buildings with special requirements from the Fire and Rescue Authority may be required to have a higher frequency.
How often must an evacuation drill be held and what does it include?
Once a year is the accepted minimum. A real drill — not reading a procedure — includes physically leaving the building, checking the actual evacuation time, and confirming that all role-holders know their role. At the end, lessons are drawn in writing and the evacuation plan is updated.
Who is responsible for the evacuation plan in an office building — the tenant or the building owner?
Overall responsibility rests with the building owner and the building manager, but the Business Licensing Law and the Occupational Safety Ordinance also obligate the employers operating in the building. In practice, it is advisable to define explicitly in the lease who is responsible for the floor safety wardens and for participation in drills.
What are protected waiting areas (Refuge Areas) and when are they required?
A protected waiting area is a fire- and smoke-resistant space — usually in the stairwell corridor — intended for people with mobility disabilities who cannot descend the stairs independently. They are required in multi-story buildings and allow people to wait safely until rescue forces evacuate them.
What is the connection between emergency PA and the fire detection system?
They are part of an integrated automation chain: a smoke detector that identifies an event automatically activates the PA, returns the elevators to the entrance floor and turns on smoke-evacuation fans. It is important to test the integration chain as a whole — not each system separately — as part of the requirements for the Fire and Rescue Authority's approval.
Do emergency lighting and exit signage require a separate test?
Yes. Exit signage and emergency lighting require an independent periodic test. A real test includes disconnecting the mains and confirming that the lighting ignites automatically and lights for the required period. Signs and lamps are also tested in artificial darkness — not just in ordinary lighting — because the failure is revealed only in darkness.
