This construction safety talk discusses the importance of wearing personal flotation devices (PFDs) when working over or near water due to the hazard of drowning. It notes that while some see PFDs as uncomfortable, modern designs have addressed these issues by making them easy to put on and take off, comfortable to work in, and ensuring an unconscious person would float face up. The talk reminds workers to properly fit their PFD harness so it is loose enough to work in but tight enough to not slip off. It also discusses the location of emergency ring buoys and rescue boats to assist anyone who falls in the water.
