Many safety professionals evaluate the quality of light at their workplace. Lighting needs to be designed with the task in mind. Different activities require certain quality and lighting levels. Ergonomically designed workplaces require enough light to see small parts, for better contrast, and be able to see moving parts much more readily. Safety concerns in parking lots lead to disaster when the public or workers trip over chains or there are trespasser concerns.
Lighting an environment is often a complex task and is an important consideration during the design stage of the building (by architects and interior designers). However, lighting should be designed for the tasks that people are carrying out within that environment. Guides to lighting and lighting assessments can seem very complex, technical documents.
Different activities need different levels of light. In general, the more detailed the task, the greater the light requirement. Lighting comes in different colors and strengths (LUX). Reflection may be a consideration. Gymnasiums and lobbies may be at 200 lux, an office at 500 lux, or production line at 750 lux. A parking lot may only require 50 lux. There are several good documents such as the HSG38 Lighting at Work for the Chartered Institution of Building Services Engineers Code for Lighting.
Why should you calibrate your light meter?
- Accurate foot-candle and luminescence measurements are important when making decisions regarding the space or spaces to be illuminated. Selection of the number of lights, the colors, the work surface reflection, soft vs. diffuse can be made wisely when the proper survey is done.
- Light meter calibration services can have an impact in a variety of ways including photosensitive materials, OSHA compliance, clean rooms, process capability, quality, liability, security concerns, regulatory violations, and the destruction of sensitive materials.
- At CIH, we can check data points of your choosing, from fractions of a lux up to 30,000 lux. We use the best iridescent sources and International Light Meter and sensors in our photonic calibration laboratory.
