When new employees join the crew. To review a recent accident in this or another crew. After a 'near-miss' incident. When a supervisor feels employees are becoming lax about safety. Usually the best time is before the work day begins.
Employees receive valuable reminders and cautions before they begin work.
It affords positive reinforcements about safety to think over during the ride to the job site, and during those aspects of the task throughout the day. On the other hand, a short meeting during or at the end of the day to discuss an incident, or lack of attention to safety is also very appropriate. It is most effective when conducted by the first-line or immediate supervisor. They are the responsible individuals, with the proper authority, who take a crew to a remote job site, and who determine the extent to which employees will adhere to safe work practices. Managers and Regional Safety Representatives can help supervisors develop ideas for tailgate safety meetings, and can help them conduct the first few sessions.
