Physical Hazards

Physical hazards include metal, glass, hard plastic, stones, bone fragments, wood, clips and other material capable of injury or choking. Natural components become hazards when size or context makes them injurious.

Raw materials, knives, grinders, saws, broken seals, light fittings, packaging, tools and maintenance work can introduce foreign material.

Supplier specifications, equipment design, preventive maintenance, tool control, brittle-material programmes and controlled packaging reduce introduction.

Visual inspection, sieves, magnets, metal detection, X-ray and other methods have different capabilities and limitations. Detection sensitivity depends on product and orientation.

Hold the affected window, preserve the object, inspect equipment and determine whether fragmentation created multiple pieces. A negative detector check does not erase a documented failure.

Trend incidents by object, source and line; challenge detection systems where used and review maintenance records. Controls should target the plausible hazard rather than a generic foreign-body list.
