As a specialist in environmental issues related to the protection of the ozone layer, I'm consolidating my area of expertise in auditing and assessment of refrigeration systems, automotive air conditioning systems and industrial refrigeration. Every year the ministry of the environment invite me to take part of the training for refrigeration specialists on good practices in refrigeration and on the protection of the ozone layer. The refrigeration specialist comes from Thiès, Kolda, Fatick, Saint-Louis, Dakar, Kaolack and all other regions in senegal. Through GST, several high-level trainings were delivered to technicians in the mines of SGO (Sabodala Gold Operations) and ESD (Equipment and Service Dakar) in automotive air conditioning (from 2011 to 2018). In 2017, GST also intervened in Mauritania at Akjoujt on behalf of MCM (Copper Mine of Mauritania).In November 2018, with the help of GIZ, I participated in a training course on Hydrocarbons in Refrigeration and Air Conditioning at ACRA (Air Conditioning and Refrigeration Academy) in Johannesburg. That's how I got the SAFE HANDLING OF REFRIGERANTS certificate.
