Taofeek Tijani, Operations Supervisor, Bentall Kennedy - Devon Research Centre
I wanted to say thank-you to yourself and the Multigas team that has put together the ASTI training sessions in Calgary. My thanks is long overdue, but heartfelt. This was the best training that I have received in my 25 years in the refrigeration trade. This training is changing the ammonia industry – it is creating a safer, more competent, more uniform and better prepared workforce.
