Read this before the site walk
“Which operations could send particles into our route today? Before we enter, check that our eye protection matches those hazards and fits with our prescription glasses. If the route or work changes, pause the walk and reassess. Who will check visitors' equipment before entry?”
Three questions to resolve
Do ordinary prescription glasses establish suitable protection? No. Corrective lenses alone do not establish suitability for the hazard. For US construction employees exposed to eye hazards, 29 CFR 1926.102(a) addresses appropriate protection, side protection for flying objects, and prescription eyewear.
How should over-glasses protection fit? It must preserve the proper position of both the corrective and protective lenses. Check the equipment instructions and fit before exposure. Do not assume a larger pair is automatically suitable.
Is one protector suitable for everything? No. Selection depends on the exposure. OSHA's nonmandatory general-industry PPE guidance discusses simultaneous hazards and compatibility. Its notes advise using a face shield over primary eye protection, rather than as a substitute. This appendix is guidance for general industry; the construction standard above governs the construction requirements cited here.
Apply it to today's route
Illustrative planning exercise: trace the proposed visitor route past a cutting station. Can the walk be rerouted or the task paused to avoid the exposure? If separation is needed, have the responsible lead select controls suitable for the actual work. Confirm the controls before admitting visitors. This is a discussion example, not a documented incident or an assessment of your site.
Discussion Points
- Which task could expose visitors to flying particles?
- What is the highest-order control we can use today?
- What change would cause us to stop the walk and reassess?
Action Steps
- Check the route and simultaneous operations. Owner: assign at the huddle. Due: before the walk.
- Confirm suitable eye protection, condition, and fit for each visitor. Owner: designated visitor lead. Due: before entry.
- Report remaining control gaps at the next huddle. Owner: the lead assigned by the crew. Due: next huddle.
Confirm the site's stop-work and no-retaliation procedures. Do not continue an unsafe activity while a protection gap remains unresolved.

Correction, September 10, 2026: removed unsupported claims that ordinary lenses always shatter and cause permanent vision loss, an unsupported seasonal trend, and a mislabeled NIOSH FACE citation. Replaced fixed staffing deadlines and inventory quantities with adaptable planning actions.
