Preparing for a workplace attack

Violent attacks on workplaces may be rare but their impact is devastating, says Laura Wilding, IOSH’s OSH Content Developer.

Preparation before compliance

The IOSH helpline often receives calls about compliance with the Terrorism (Protection of Premises) Act 2025 – often referred to as Martyn’s Law.

But there’s no reason all businesses shouldn’t take a preventative approach to fatality and harm caused by terrorism and the kind of violent intrusion we tragically saw in London and New York in late July. Neither business would have been subject to the Act had it come into force.

The devastating murders in Southport in July 2024 took place at a dance class in a business centre – which could reasonably be said to be an unlikely target for violent intrusion.

The risk is real

At global and national levels, the risk of terrorist attack is not considered unlikely. In fact, it is variously described as Substantial (UK), Acute (EU) and Probable (Australia).

"Many recent attacks aren’t officially classified as terrorism, making them harder to quantify — yet they’re increasingly visible in the news."

Demonstrations such as anti-immigration protests outside hotels housing migrants are becoming more frequent, with employees potentially at risk.

Risk assessment and employee training

In the UK, Counter Terrorism Policing work with businesses in a wide range of industries to help control risks associated with terrorism. And they can provide support and advice to OSH professionals.

In general, all employees should be trained on:

how to maintain security protocols (eg checking passes before allowing entry to premises, where possible)
their first responsibility in an emergency (eg use of panic buttons, silent-calling emergency services)
relevant lockdown and evacuation procedures, including where to hide safely if windows are broken (etc)
‘Run Hide Tell’ guidance (or similar) and how to follow it.

Is it reasonable?

OSH professionals may or may not be formally responsible for security, but they do have a moral and legal obligation to take reasonable steps to prevent harm to workers. Is it unreasonable to include the control of risks associated with violence and terrorism?

A collaborative approach

For those working for businesses who have security teams in place, a collaborative approach may help to control risk more effectively. OSH professionals can support the development and implementation of training and drills, sharing knowledge and skills of fire safety protocols.

All employees should understand that while unlikely, these events do happen. Everyone can reduce the risk of harm to themselves and others by preparing for the possibility.
