The Administration of Occupational Safety and Health wishes to draw attention to the fact that all companies, including tourism companies operating in areas where there is a risk of geothermal energy pollution, shall carry out appropriate risk assessment and response plans in accordance with Regulation no. 920/2006 .
The key point is that all employees know the risk assessment, response plans and use appropriate personal protective equipment if other protective measures are not possible. Businesses are also advised to monitor and monitor information on civil protection in the preparation of risk assessment and response plans.
Hazardous gases due to geothermal power
Employees who work for measurement, observation, guidance or other work near geothermal energy must take appropriate precautions for the risk of toxic and dangerous gases.
The greatest danger arises from gases that are heavier than the atmosphere, and can therefore be transmitted to the ground, forming mortal gills in dams and gaps.
Examples of such gases are sulfur hydrogen (H2S, hydrogen sulphide), sulfur dioxide (SO2) and carbon dioxide (CO2).
Special care should also be taken when entering a closed space where geothermal activity is present, such as pour and ice hollow that can form in glacier passages under certain conditions. In these cases, special attention must be paid to sulfur hydrogen (H2S, hydrogen sulphide), sulfur dioxide (SO2), carbon dioxide (CO2), and carbonic acid (CO, carbon monoxide).
It is necessary to measure the concentration of gases in enclosed spaces. If possible, use a single-drill gas meter that emits a warning sound if the concentration approaches the threshold. The minimum requirements for such measurements include sulfur hydrogen (H2S), sulfur dioxide (SO2), oxygen (O2) and carbonic acid (CO).
If gas gases are used with gas oil, they should at least protect the gases SO2 and H2S and preferably all harmful gases found in the space.
Care should be taken to relieve gases of respiratory masks, as many types of gases are usually involved, and the filters can be quickly absorbed.
