Raw Data for Algorithm Evaluation, 2013

Sewage work carries an increased risk of serious health problems and fatal accidents. The main reason for this is hydrogen sulfide (H2S). Knowing how and where exposure to hydrogen sulphide (H2S) occurs, as well as good work practices including the use of safety equipment, will reduce risk and save lives and health. By collecting measurement data from alarm equipment for gas, we will be able to see when and where the risk is greatest, so that risk-reducing measures can be implemented where they have the best effect.

There is great variation in the technical standard of sewage systems around Norway, and also in the knowledge of risk factors associated with sewage work. Unfortunately, gas sensors are not used everywhere, or the wrong sensor is in use. This work will develop knowledge and help employees and employers throughout municipal Norway, to make good choices for risk and exposure reduction when designing facilities and when choosing alarm and protection equipment, as well as for training and education of sewage workers. Hopefully the knowledge will also prove useful outside Norway.

The data file made available here is, via the published algorithm, used to present a risk figure that brings together the average value and top exposure in one number.
