Safe Working Environment Surveys 

LUX (Light) Surveys

Allrig understands that good lighting is vital to safety and performance. Our light measurement surveys investigate the illuminance flux (LUX) levels of general lighting and task lighting on vessels and workplaces. The main objective is to determine whether the various lighting systems comply with minimum standards to accommodate personnel’s visual task performance and to facilitate their movements, wellbeing, and safety on board vessels and workplaces. Surveys determine the potential hazards arising from the work activity under the current lighting condition in the workplace, such as insufficient illumination, excessive contrast, glare or flicker, and evaluate the risks and decide whether improvement measures are needed to protect the employees.

Acoustic Emission (Noise) Surveys

Allrig offers noise level surveys to identify areas that are outside of the specified auditory limit or zoned incorrectly. Our expert surveyors will highlight the probable causes and provide recommendations for rectifying the zoning, reducing the noise level where possible and offer mitigating solutions.  Surveys can include an evaluation of signage to ensure it relevant to operating auditory levels.
