6. Knowing Who Is On Site

Why visibility matters under Martyn’s Law. Learn how tracking who is on site improves safety, response, and accountability.

The Importance of Visibility

One of the most practical aspects of preparedness is understanding who is on site.

In any incident, having clear visibility of people within a venue or event helps support faster and more effective decision-making.

This aligns with ProtectUK guidance, which emphasises awareness and control.

Who Needs to Be Considered

It is not just members of the public.

You should also account for:

  • Staff and crew
  • Contractors and suppliers
  • Volunteers
  • Media and VIPs

Each group contributes to the overall environment and should be considered in planning.

Supporting Safer Operations

Knowing who is on site helps to:

  • Improve coordination during incidents
  • Reduce confusion between teams
  • Support evacuation or lockdown procedures
  • Strengthen accountability

It provides clarity in situations where clarity is essential.

Entry and Access Processes

Structured entry processes play a key role in maintaining visibility.

This may include:

  • Ticket validation
  • Accreditation or passes
  • Controlled access points
  • Zone-based permissions

These measures do not need to be complex, but they should be consistent.

Temporary and Open Sites

Temporary events and open land sites are not exempt.

Even without permanent infrastructure, there is still a responsibility to maintain oversight and control.

Conclusion

Visibility supports safety.

Understanding who is on site is a simple but powerful way to improve preparedness and response.
