Restore visibility and physical protection.
Machine guard panels can become scratched, crazed, cracked, drilled for unplanned modifications or damaged by impact. Replacing the sheet is an opportunity to check the mounting arrangement, unsafe gaps, missing fasteners and recurring damage rather than duplicating a poor detail.
Three routes to an accurate replacement.
From a drawing
Manufacture to an approved dimensioned drawing with material and finish defined.
From a sample
Measure and reproduce an existing panel, allowing for damage and known fit issues.
From a survey
Capture the machine geometry on site when the panel is missing, complex or part of a wider upgrade.

Signs a panel needs review.
- Cracking from holes, bends or panel edges
- Crazing, cloudiness or chemical attack
- Deep scratching that prevents safe process observation
- Loose or missing fasteners and panel movement
- Unplanned cut-outs creating access to hazardous parts
- Permanent deformation following impact
- Door misalignment or interlock nuisance faults
Do not operate machinery with a guard that no longer provides the intended protection. The responsible dutyholder should place the equipment in an appropriate safe condition until a competent assessment and repair are completed.
Frequently asked questions.
Overall width and height, thickness, corner radii, hole diameters, hole-centre positions, cut-outs and mounting details are useful. Photographs with a scale and the original panel help reduce ambiguity.
That depends on whether visibility is important to the safe task and whether scratching masks cracks, chemical attack or damage. A competent inspection should determine whether the panel remains suitable.
Project drawings and an agreed part reference can support repeat supply, subject to revision control and confirmation that the machine and mounting arrangement have not changed.
