Concrete is the most commonly used man-made material on earth. The uses of concrete range from structural applications to piping, drains, and pavers. Buildings, bridges, roads, and more could not be constructed without this important material.
Working with concrete introduces safety hazards that can place workers in danger and put their lives at risk. Concrete mixing plants must perform regular maintenance on mixers to ensure proper working conditions and efficiencies. Maintenance can involve accessing the mixer’s entry points for cleaning and servicing of paddles. To ensure worker safety, power must be isolated prior to entry of the mixer and at no time during maintenance can power be inadvertently re-energized.
Implementing a trapped key interlock safety system into the safety procedures for power isolation can eliminate human error and drive a pre-determined sequence of operations to ensure worker safety.
