The NASUWT has had concerns for some time that the advice given to schools around lockdown procedures is inadequate.

All staff and pupils need to know how to respond in a lockdown situation.

It should be stressed that the probability of an incident involving an intruder(s) seeking to cause harm in any school is very low. However, in exactly the same way that schools should prepare for a fire, they should be prepared to respond to all eventualities.

This guidance is not intended solely for use in cases of intruders, but could also be employed whenever the safety of staff and pupils could be at risk, for example in cases of civil disturbance or a major fire or other incident nearby.

This guidance is intended to give an overview of what lockdown procedures should look like and applies to all schools in all nations of the UK.


  • There is a threat to schools from a terrorist/extremist weapons attack.

  • Presently the threat is LOW.

  • However, it is LOW threat not ‘No threat’ and therefore schools should have a contingency plan and procedures in place to deal with it similar to fire procedures.

  • Unlike fire procedures, which in most cases mean evacuating to an external assembly area, this will most likely require ‘invacuation’ to a safe area(s).

  • Perhaps better described as temporary refuge areas, these are places that are safer than staying where you are and safer than immediately evacuating.

  • The attached guidelines will assist in the production of a contingency plan and provide advice on the development of procedures.

Contingency plan guidelines


The aim is to protect children and staff from a terrorist/extremist weapons attack until the police arrive to take control of the situation.


Carry out a vulnerability assessment of the school’s campus using the ‘traffic light’ system. Using a plan of the campus, colour the areas red, amber or green depending on how vulnerable they are to attack, with red being the most vulnerable.

Note: The easiest way to do this is to put yourself in the position of the attacker and ask yourself how would you carry out an attack and where are the easiest places to gain access?


The green areas are the most likely to provide protection or that are difficult to find. Carry out a space assessment using approximately 0.5m2 per person to calculate how many can be accommodated. If insufficient, then some of the amber areas may have to be used.

Note: In making the choice of where to go, some other factors need to be considered.

  • It is best to move people short distances - longer routes can lead to disruption and panic.

  • Routes to safe areas also need to be safe, e.g. do not take people outside to move back indoors somewhere else.

  • People need to be kept informed, every couple of minutes, while in these areas. This can be done using area-defined public address (PA) systems or messaging on tablets.

  • Ideally, facilities such as toilets and water should be nearby.

  • It has been found that groups (classes) who know and work with each other are better kept together as this lowers stress.


Having calculated where people can be safely and comfortably accommodated, it is now necessary to write the procedures.

There are three key factors:

Time: As with a fire alarm, consideration should be given to using some form of panic alarm. This must be significantly different from the fire alarm to avoid confusion. The alarm can be qualified by the use of a PA system. Positioning of the panic alarm(s) will most likely be in the red areas, e.g. near the entrances, main office and control room.

Note: Sometimes, it is very difficult to realise that an attack is taking place, so time is of the essence.

Control: Control of an incident is essential, otherwise there is a strong chance of panic. An incident controller/co-ordinator should be nominated to take charge. Because of holidays/sickness/external meetings etc., it is advisable to nominate at least three incident controllers to ensure that one is on site at all times, during and after school. These people will require a small amount of training/guidance to instil confidence in the procedures.

Consideration should be given to the use of pagers. The duty incident controller picks up the pager on coming to work and returns it to the office on leaving. The caretaker has it out of hours. Not only is this a quick way to contact the incident controller, it also alarms if taken off site, thus ensuring there is always an incident controller available.

Control is generally best operated from a control room. This room will have CCTV monitors and recorders, access control data, alarm access, PA system initiation and good communications such as phone, e-mail etc. This should be in a safe area or be well protected so that it is not compromised during an incident.

Inevitably, some schools will have these facilities in their main office which could be near the entrance and hence be vulnerable in the initial stages of an attack. In this case, consideration should be given to having duplicate facilities elsewhere in a safe area or upgrading the protection of the office. This can be done relatively cost-effectively and with little disruption - contact us if advice is available if required.

Simplicity: Procedures must be kept simple and be usable under stress and at different times of the day, e.g. during arrival of students, lunchtime and during after-school activities.

It is strongly suggested that fire marshals are used to implement the procedures as they already have a responsibility for guiding and accounting for students in a fire incident. They will need some training and practice in these new procedures.
