Mobile crane hand signals poster: Interestingly enough, when we visit work sites, we come across situations where there are no pre-established forms of communication or hand signals. This is often the case on construction sites when the team is compiled of outside workers, brought in to do specific jobs before moving on to the next crane job. And yet, OSHA makes it clear that all forms of communication need to be agreed upon, understood and used. As far as mobile crane operators are concerned, direct communication is always ideal. But when that is not safe or feasible (which is often the case), then mobile crane hand signals should be used. Everyone should understand what each hand signal means. However, there should only be one designated signaler at a time. The only exception to this rule is the signal for “emergency stop.” Anyone can give this signal at any given time, and it should be obeyed by the mobile crane operator immediately no matter who gives it. With this in mind, we hope this mobile crane hand signals poster will help you solidify your own hand signal program so everyone is on the same page.
Did you know? After investigating a recent fatality, OSHA discovered several issues relating to mobile crane hand signals. First, the work site did not have the mobile crane hand signals posted for the workers to see. Second, the injured worker had not received any formal signaler training. As a result, the mobile crane hand signals he was using were not the same as the ones the operator was used to.
