A Lighting Survey Checklist ensures a structured approach when assessing workplace illumination. Below is an extended version of a basic checklist:
| Checklist Item | Yes/No | Remarks |
|---|---|---|
| Is there sufficient light for tasks? | ✅ / ❌ | |
| Are there any troublesome reflections? | ✅ / ❌ | |
| Is there glare along the normal line of sight? | ✅ / ❌ | |
| Are there bright, shiny objects causing distractions? | ✅ / ❌ | |
| Are there frequent transitions between extreme lighting conditions? | ✅ / ❌ | |
| Are light fixtures covered properly to diffuse light? | ✅ / ❌ | |
| Are lights placed correctly to avoid flickering or shadows? | ✅ / ❌ |
Using this checklist ensures a thorough evaluation of lighting conditions and helps in maintaining a safer work environment.
How can we prepare a lighting survey checklist?
For an easy preparation of survey checklist you can always make groups. These groups can be based upon the type of work or lighting requirements, etc.
Talking about the format you can keep it as a simple YES/NO format or keep a format based on remarks or both.
Coming to where our main focus should be is what all points to be included. In the survey checklist, there are certain basic points which should be included, but depending upon the aim of your survey checklist, feel free to add or modify points.
Following are some basic points which can be considered;
- Sufficient light for task
- Troublesome reflections
- Glare along or near normal line of sight
- Bright shiny objects out of view
