SAT working safety aspects and legislation assessed

Baltic Slurry Acidification project has released a report on working environment and safety when using slurry acidification techniques (SATs). The report presents relevant EU legislation and a general overview of safety needs when handling acids. Additionally, the report describes country specific regulations and conditions for implementation and use of slurry acidification technologies.

The report focuses on slurry acidification with sulfuric acid, because sulfuric acid is not only the most suitable acid for acidifying slurry, but also the most cost-effective. Furthermore, it supplies soil with sulfur, which is a necessary macronutrient for plants. All field trials in the project are conducted with sulfuric acid.

There are several EU regulations governing the sale of chemicals, including specific requirements for hazard classifications and labelling, such as REACH (EC 1907/2006) and CLP (EC 1272/2008). Also, there are many regulations for occupational safety and health, work environment and use of personal protective equipment to be followed. The correct personal protective equipment is imperative when sulfuric acid is handled.

For each of the Baltic Sea Region countries, national regulations and general aspects on working environment, personal safety, safe storage and transport are presented. This report has also surfaced cases in which existing regulations may require further modifications in the design and application of SAT technologies. For instance, the German traffic regulations (StVO) have already prompted further development of the in-field SAT system, where the IBC acid tank is not loaded on the front of the tractor but on the tanker. Also, there are example scenarios of how to handle the acid in order to prevent accidents when using SATs suitable for the slurry handling systems in each country. All eight countries involved in the project are represented by individual chapters.

The report includes a checklist for practitioners to observe in acquiring and using SAT systems and outlines seven simple recommendations to follow when implementing slurry acidification technology on farm level.


The report is available here.
