Every workplace injury happens at what I call the “sharp end” the moment when a worker’s hands meet the task, when energy sources are present, when a single error can mean the difference between going home safe and not going home at all.
The question that matters is simple: what stands between your workers and harm at that moment?

The problem with safety thinking
Too much contemporary safety thinking focuses on culture, mindset, and organisational values. These things aren’t irrelevant, but they’re not what stops a fitter being electrocuted when isolations fail, or a process operator being exposed to a chemical release.
What stops those things is a chain of practical controls each one doing a specific job, each one relying on the others.
I developed the Control Approach as a way of making this chain visible and testable. It’s not a theory. It’s a description of what actually has to be in place for workers to be protected when they’re doing hazardous work.
The five elements

1. Safety policy and arrangements
This is the foundation. Without well-founded policies covering behaviour, substance misuse, manual handling, emergency response, chemical agents, isolation everything else falls apart.
Policies aren’t bureaucracy. They’re the decisions your organisation has already made about how work will be controlled. If these are absent or deficient, workers at the sharp end are exposed before they even start the task.
2. Risk assessment
If your risk assessment process is inadequate, the consequences flow directly to the sharp end: hazards remain unidentified, people at risk aren’t recognised, control measures aren’t selected or embedded in procedures, and legal compliance becomes impossible. Risk assessment isn’t a document. It’s the process by which you identify what can hurt people and decide what to do about it.
3. Safe systems of work
Risk assessments identify hazards and controls. Safe systems of work or safe operating procedures turn that information into a methodical sequence of steps that workers can follow.
Without them, workers make it up as they go along. The thinking doesn’t get done. The controls don’t get organised. Training becomes vague. Legal requirements go unmet. This element is critical: the other controls can’t function without it.
4. Permit to work
One of the formal mechanisms used to verify that high-risk work has been properly planned, authorised, and coordinated within this wider control approach is the use of Permit to Work systems.
Permits should never be overused doing so degrades the system. But for tasks where simple human errors could cause fatalities or serious disabling injuries, a permit to work provides something essential: verification by two competent persons that controls are in place and functioning before, during, and on completion of the task.
If the permit system is absent or deficient, there’s no check that isolations are correct, no confirmation that the safe system is being followed, no formal barrier between the worker and harm.

5. Dynamic risk review
Despite well-founded policies and systems, workplace conditions change. Equipment moves. Circumstances shift. The worker at the sharp end must remain vigilant and think for themselves.
A personal risk review using a predefined checklist prompts the worker to verify that critical controls are in place before starting. If something’s wrong, they stop and report before exposing themselves to risk.
This is not a risk assessment. It’s a user check. The last line of defence.
Why this matters
The Control Approach isn’t complicated. It’s a description of what competent organisations have always done: build layers of practical control so that when a worker reaches the sharp end, the systems have already done the work of making the task safe.
Each element relies on the others. Remove one, and the chain breaks. The question for your organisation is straightforward: can you trace each element from policy through to the worker’s hands on the task? If you can’t, you’ve found where your next incident is waiting.
