Martyn's Law Standard Tier checklist

1. Confirm your number

Write down the most people you expect on site at the same time at your busiest, staff included, and how you worked it out.

2. Name your Responsible Person

Usually the owner, tenant or licensee. Make sure they know they are accountable.

3. Get ready to notify the SIA

Diary the start date once it's announced. You'll have three months to notify through the SIA's online system.

4. Write your evacuation procedure

How staff get everyone out safely, which exits to use and where to go, taking account of where an attacker might be.

5. Write your invacuation procedure

Where people can shelter inside, away from doors and glass, and who moves them there.

6. Write your lockdown procedure

Which doors and shutters can be locked quickly, who does it, and how you stop people leaving into danger.

7. Plan how you'll communicate

How you'll alert all staff at once, tell customers what to do, and call 999.

8. Agree arrangements with neighbours

If you share a building or entrance, agree who does what with the other occupiers.

9. Brief your team

Walk every member of staff through the procedures and record who has been briefed.

10. Keep it up to date

Review after any change to layout, capacity or staffing, and at least once a year.
