Safety Training

Johnson & Jonet has grown to the point we have had to hire a dedicated safety consultant to make sure job-site safety is a number one concern. Our company stresses safety importance on and off the job site. There is always a “chance” someone could get injured, so every precaution is taken to avoid injuries. With safety training, and on site safety inspections, our company’s modification rate has been steadily decreasing. We not only work with the site foreman, but also with our site workers to improve their safety on the job site. Our employees understand that safety is not only for the company’s aspect but for their own family also. Johnson & Jonet provides training and all safety equipment needed to all employees for their protection against injury.
