Safety Letter from Director of Safety
At MZI we apply the science of behavior change to our real world every day safety challenges. Our process creates a safety partnership between management and our employees that continually focuses our people's attention and actions on their, and others, daily safety behavior. We focus on what our people do, analyze why they do it, and then apply research-supported intervention strategies to improve what our people do. At its very core, our safety methodology is based on a larger scientific field called organizational behavior management.
Our safety management system is applied to internalize hazard avoidance strategies or administrative controls, including use of personal protective equipment which is not used in preference to the implementation of our practical safety measures.
Our safety program includes everyone at MZI. We achieve change in behavior through change in policy, procedure and or systems. These changes could not be accomplished without the buy-in and support from all involved in making these decisions.
Our safety methodology is not based on assumptions, personal feeling, or common knowledge. Our safety methodology is based in fact. Safety first, last and always.
