Optical lab, workshop and process hazards

Some optical practices carry out lab, workshop or repair tasks. COSHH can apply to the substance itself and to any process that creates dust, mist, vapour or contaminated waste. Support staff should only perform tasks for which they are trained and authorised.
Possible optical process hazards
- Lens edging: dust, swarf, slurry, coolant mist and residues from cutting or edging lenses.
- Polishing and repair: polishing compounds, adhesives, solvents, dyes, sprays and frame repair products.
- Cleaning machinery: fluids, contaminated cloths, residues, splash risk and waste from equipment maintenance.
- Ventilation and extraction: local controls that may be needed to reduce dust, mist or vapour exposure.
- Waste: used wipes, contaminated containers, dust, slurry or product residues that need the correct disposal route.
Boundaries for support staff
Do not assume a workshop task is safe because it is small or quick. Follow local training, machine instructions, extraction or ventilation requirements, cleaning methods, PPE rules and waste procedures. Report missing guards, blocked extraction, damaged containers, unusual smells, dust build-up, poor ventilation or symptoms such as coughing, eye irritation or skin problems.
Do not dry sweep dust into the air unless the local procedure explicitly allows it. Do not improvise with solvents, adhesives, compressed air, sprays or unapproved cleaning methods.
In workshop areas, the process can create the hazard. Dust, mist, vapour and residue controls matter as much as product labels.
