A brief History

GSI was incorporate in 1985 and established to meet the need identified for professional gas training in the workplace.

The owner, Karl Peter Rohlssen initially qualified as an Automotive Engineer and later completed a Diploma in Business Mangement before furthering his studies at the BAM institute in Berlin, Germany.

While working for a large international welding company Peter identified the need for safety training for people working with gas and GSI was born.

In September 1986 Peter exhibited at a mining show in South Africa which he funded using the last of his working capital. He had 1 visitor on the Monday, on the Tuesday, 2 visitors. On Tuesday evening news broke about a mining incident at Kinross that was gas related and resulted in serious injuries and fatalities.

A gas explosion was reported and the consequence of this, and related circumstances, resulted in over 80 deaths and numerous injuries. It was an Oxy/Acetylene related incident and the fatalities increased to 150.

On Wednesday morning there was a lot more interest in Gas Safety and at 08:45 there were many people ask questions and collecting brochures. The tragic incident highlighted both the dangerous consequence of not following gas safety procedures and getting the people working with gas trained to both understand and work with gas safely.

Later Peter invested a lot of time with the then world leader on gas. He was based at the BAM Institute in Germany. Knowledge that has contributed to making GSI a world leader in the Gas Safety field. Peter's knowledge and experience has resulted in him being invited to present at many international gas related conferences.
