Machine Guarding and Isolation: What Recent HSE Enforcement Should Prompt Manufacturers to Review
Recent HSE enforcement action involving machinery has highlighted an important reminder for manufacturers: having machinery safeguards in place isn't enough. Businesses need to make sure those safeguards work in practice and that machinery can be safely isolated when intervention is required. Effective machine guarding and isolation arrangements help manufacturers prevent access to dangerous machinery parts and protect employees during cleaning, maintenance and other intervention work.
Recent cases involving cleaning, maintenance and machine blockages show why it's worth reviewing existing arrangements before an incident occurs.
Why Machine Guarding and Isolation Matter
Under the Provision and Use of Work Equipment Regulations 1998 (PUWER), businesses must take effective measures to prevent access to dangerous parts of machinery.
This includes considering whether:
Dangerous moving parts are adequately guarded
Guards and safety devices are working correctly
Employees can access dangerous areas during normal work
Guards can be easily removed or bypassed
Machinery changes have affected existing safeguards
A machine may have been operating safely for years, but changes to equipment, processes or working practices can introduce new risks.
What About Cleaning and Maintenance?
Some of the greatest risks can occur when machinery isn't operating normally.
Cleaning, maintenance, adjustments and clearing blockages can expose employees to moving parts that would normally be inaccessible.
Recent HSE enforcement has highlighted cases where workers were seriously injured while cleaning or attempting to clear machinery.
This raises an important question:
What happens when something goes wrong?
If a machine jams, is there a safe procedure for clearing it?
If cleaning requires access to dangerous areas, can the machinery be safely isolated?
If maintenance is required, does the person carrying out the work know exactly how to isolate the equipment?
These situations should be considered as part of the machinery risk assessment, rather than treated as exceptions.
Is Your Isolation Procedure Effective?
Stopping a machine isn't necessarily the same as safely isolating it.
Businesses should consider whether their arrangements prevent unexpected start-up or movement while work is being carried out.
This may involve isolating and locking off energy sources, as well as considering stored energy such as:
Electrical
Hydraulic
Pneumatic
Mechanical
Pressurised systems
Employees should also understand when isolation is required and how to carry it out correctly.
Does Your Risk Assessment Reflect Reality?
A risk assessment should reflect how work is actually being carried out today.
Manufacturers should consider reviewing their machinery risk assessments following:
Equipment or process changes
Recurring machine faults or blockages
Changes to cleaning or maintenance procedures
Near misses or incidents
Changes in employees or contractors
Changes in working practices
It's also worth asking whether employees are actually following the documented procedures.
The question isn't simply "Do we have a procedure?" It's "Does the procedure work in practice?"
A Quick Review for Manufacturers
Recent HSE enforcement provides a useful opportunity to review your arrangements.
Consider checking:
✓ Machine guarding and safety devices
✓ Isolation and lock-off procedures
✓ Cleaning and maintenance arrangements
✓ Machine blockage procedures
✓ Risk assessments and safe systems of work
✓ Employee training and competency
✓ Inspection and maintenance records
✓ Previous incidents and near misses
The aim isn't to create more paperwork. It's to make sure your controls are appropriate, understood and working in practice.
Don't Wait for an Incident
Machinery risks can become easy to overlook when equipment is familiar and processes have been in place for years.
Regular reviews can help identify where controls may no longer reflect the way work is being carried out and where additional measures may be needed.
Good machinery safety isn't just about keeping equipment running. It's about making sure people can operate, clean and maintain it safely.
