When Night Work Was Not Visible Enough

The Scenario

A nighttime setup used devices that had lost their reflectivity, and the work lighting created glare toward approaching drivers. Approaching the work after dark, drivers had little to read.

The Compliance Issue

Night work adds a visibility challenge. Devices that are not visible in low light, and lighting that creates glare, leave drivers without the guidance a daytime setup would provide.

How It Surfaced

The poor visibility and glare were flagged during a night check of the setup.

How It Was Resolved

Low-visibility devices were replaced with retroreflective ones and the lighting was repositioned to light the work without glare toward traffic.

How to Prevent It Upstream

Night visibility is planned: device retroreflectivity, lighting placed to avoid glare, and worker high-visibility apparel are confirmed before running the work after dark.

Lessons

• Night work needs devices that are visible in low light.
• Lighting must help drivers, not blind them.
• Visibility is planned before the shift, not fixed mid-shift.
