Prevent access
Add fixed panels, infills, local covers, tunnels or perimeter guarding around identified hazardous movement.
Existing work equipment
PUWER machine guarding upgrades.
Turn identified guarding, access and safety-control shortcomings into a prioritised engineering scope for machinery already in service.
Direct answer
What does PUWER Regulation 11 require?
It requires effective measures to prevent access to dangerous machinery parts or stop dangerous movement before a person enters the danger zone, following the protective hierarchy in Regulation 11.
Primary references: PUWER Regulation 11 and the HSE PUWER overview. The proposal defines the exact assessment and remedial boundary.
From finding to practical change
Close the gap without overstating the outcome.
The Provision and Use of Work Equipment Regulations 1998 (PUWER) places duties on those who own, operate or control work equipment. HSE guidance explains that effective measures should prevent access to dangerous parts, normally using fixed guards and, where routine access is required, interlocked guards where appropriate.
Our role can begin with a guarding-focused review or with findings already identified by your competent assessor. We define, design and implement the agreed machine modifications, with outputs proportionate to that boundary.
PUWER applies to work equipment in use; age alone does not remove the duty to manage risk.Guarding remedial work
Typical actions following a review.
Control opening
Provide appropriately designed interlocked doors or removable guards where access cannot remain tool-controlled.
Manage delayed hazards
Review stopping time and guard locking where risk remains after the stop command has been issued.
Prevent unexpected movement
Improve reset location, visibility, restart logic and related control behaviour within the agreed scope.
Repair and maintain
Replace damaged panels, worn hinges, unreliable switches and weak fixings; define ongoing inspection needs.
Update records
Provide the drawings, component details, test records and residual actions included in the proposal.
Prioritised improvement
A route from urgent defects to planned upgrades.
Confirm
Verify the machine, finding, hazard and existing control measures before prescribing a solution.
Prioritise
Separate immediate controls, near-term repairs and modifications requiring a planned shutdown.
Implement
Engineer and install physical and control changes under a clear, agreed modification boundary.
Maintain
Record inspection, testing, spares and follow-up actions so improvements remain effective.
Existing assessments, drawings and known defects improve the speed and quality of the engineering review.Important project boundary
Guarding review, PUWER assessment or remedial implementation?
These are different services. A guarding survey may focus on dangerous parts and access. A full PUWER assessment has a wider scope. Remedial implementation may be based on findings produced by another competent party.
The quotation should state which role Oxford Machine Guarding is performing and which decisions remain with the employer or other responsible dutyholder.
General information only. This page is not a machine-specific risk assessment or legal advice. The responsible dutyholder should confirm the applicable requirements and assessment scope for its equipment.
PUWER and retrofit FAQs
Clarifying the scope.
Does PUWER apply to older machinery?
HSE states that PUWER aims to ensure work equipment is safe to use regardless of age, condition or origin. Duties depend on the work equipment, its use and who controls it.
Is a guarding survey the same as a full PUWER assessment?
Not necessarily. A guarding-focused survey may examine only defined hazards and access points. The proposal should state whether it covers a full PUWER assessment, a guarding review or implementation of existing findings.
Can actions be phased?
Yes. A documented plan can distinguish immediate restrictions or controls from repairs and larger upgrades to be completed during planned shutdowns. Priorities should follow the risk and dutyholder’s assessment.
Does replacing a guard create new UKCA responsibilities?
The implications depend on the significance of the modification, changes to intended use and the wider machine or assembly. HSE publishes guidance on refurbished and modified machinery; the responsible party should assess the exact change.
