The Risk You Don't See: Why Grey Spaces Matter in Security

In our experience protecting high-profile individuals and complex environments, incidents rarely happen in the obvious places. They happen in the gaps: the grey spaces where attention drops, and responsibility becomes unclear. These are the moments where situational awareness makes the difference.

What Are Grey Spaces?

We define these as areas or moments that fall outside structured security measures. They’re not necessarily unsafe, but they are often unmanaged, which can increase the risk of an incident happening.

Examples include:

  • Entrances just outside CCTV coverage
  • Transitional areas (car parks, corridors, loading bays)
  • Perimeter roads and footpaths
  • Shift change periods or handovers
  • Public-facing areas with no clear ownership

When Awareness Changes Outcomes

Two very different incidents highlight these areas:

  1. Attempted Attack at St James’ Hospital, Leeds (2023)
    While outside St James’ Hospital, a patient, Nathan Newby, noticed a man who appeared out of place. Acting on that instinct, he approached the individual to check on his welfare. During the interaction, he discovered the man was carrying a backpack containing explosives.

    His decision to engage calmly and without hesitation, led to authorities being alerted and the threat being stopped before it could escalate. He wasn’t tasked with that responsibility. He simply recognised something was wrong and chose to act.

  2. The Glasgow Airport Attack (2007)
    When a vehicle was driven into the terminal building in a terrorist attack, it wasn’t a security system that immediately stopped the threat. It was people.

    One of them was baggage handler John Smeaton, who intervened without hesitation. His actions, alongside others, disrupted the attack before it escalated further.

    He wasn’t “on duty” for that role. He was simply aware, decisive, and willing to act.

How To Respond: Calm, Controlled, Effective

Being “the right person at the right time” isn’t about heroics. It’s about making good decisions under pressure.

A simple framework:

  1. Pause and Assess
    - What exactly am I seeing?
    - Is there an immediate risk?
     

  2. Create Space
    - Distance is safety
    - Avoid escalating unnecessarily
     

  3. Communicate Early
    - Alert security, management, or emergency services
    - Be clear, concise, and factual
     

  4. Act Only Within Your Capability
    - Intervention isn’t always physical. Often, the most effective action is early reporting that allows the right response to mobilise.

For Businesses: Closing the Gaps

If you’re responsible for a workplace or public-facing environment, consider:

  • Mapping your grey spaces, not just your protected areas
  • Training staff in behavioural awareness as well as procedures
  • Clarifying ownership of transitional zones
  • Encouraging reporting culture, where no concern is dismissed

The difference between incident and prevention often comes down to one person noticing something early and choosing to act. That could be a member of staff. A passer-by. Or you.

At Premier Protection Security, we’ve spent decades operating in high-risk environments. The consistent truth is this: the right mindset, applied at the right moment, is one of the most powerful security tools there is.
