We invested the time and money in the Tetra system to allow our workforce to work in a safer manner. Pretty much all of our staff, of which we trained about 90 people commented that it was one of the best courses they have been on. They found it informative and really enjoyable and also commented how good the system is to use. Not only has this training and system meant our work force are working at height as safe as possible from a ladder, but it has also saved us money as we can now send a single operative on a job rather than two people. This really is a great system with enjoyable and informative training to back it up.
