A good safety consultant will come up with a solution when you have workers in different places, should be nothing wrong with a Zoom meeting or even a conference call. I had one consultant actually hold back the crew to make the meeting last 30 minutes I found one way to keep guys engaged is to take one procedure go through it and get comments back why or why not it works. Giving the guys a heads up ( a couple days ahead of time ) on what's going to be discussed gives them a chance to think of things as well. Knowing how to chair a meeting makes things go way better, there's some good on line courses with tips on how to deal with some of the personalities that folks have and how to keep the meeting on topic.
