Mast Climbing Work Platforms are marvelous pieces of equipment. And safe too, provided you behave yourself. Actually it isn’t very difficult to use these platforms—provided you have been trained. That isn’t unusual. After all, if you want to use any scaffold or aerial platform you have to be...

Will training increase the safety of suspended scaffolds? Will more safety features increase the safety of suspended scaffolds? Wait—is there a...

As a prime example, take the standards that relate to the height of toprails in a guardrail system. Here are the numbers: 36; 38; 39; 42; 45; 48.
