What does training extended mean? This means that you train the forklift operators on safety procedures for the forklift, but also those that work around the forklift. If both have a clear understanding of the safety standards and refrain from taking chances and getting hurt, then the training that has been extended can be successful. However, in a forklift accident, it only takes one. One person who breaks with the rules, even a temporary worker, and try to run quickly behind the forklift and get pinned. That’s why that extra precaution of forklift pedestrian safety with the S3 forklift safety system comes into play.
