In addition
In addition to all of the above good suggestions concerning safety, open points, grounds, responsibilities.......
Any special tools, dies, etc that are not used on a daily basis and carried on each truck. Break out a set of instructions and go over proper stip backs, insulation removal lengths etc. Especially if it has been awhile since your crew has done any UG. This also helps catch slight variations in measurements from manufacturer to manufacturer. Even with the same manufacturer sometimes dimensions change, die requirements change, etc. Check the canaries before leaving the yard if working in manholes/vaults. Check for proper harnesses. Check where the work is to be performed to see if lane closures will be needed for mid street vaults.
Many assume that because things are redundant that they don't have to go over every little detail. By going over every little detail it helps the crew leader ascertain the mental state of his crew sometimes and helps ensure everyone is on the same page. Complete tailboards only take a few minutes and can help lessen the chances of not only accidents that cause injury but also those uh ohs that cause work to not be as productive due to mental mistakes.
Take only what you earn, give only what you can, learn to respect yourself before you can expect to respect anything or anyone else.
