Objective: To understand and develop a color coding system for farm and workplace hazards.

Trainer’s Note

A consistent color system, denoting color-hazard relationship alerts employees to safety hazards. Knowing the system increases employee safety. Tour the operation, pointing out the different examples of color coding used and the hazards identified. ALL EMPLOYEES should be familiar with the color coding system. Reassigned workers should learn the color codes in their new area. Review the true or false quiz.

Background

Below is the recommended guide for a color coding system. Post a copy of the color coding system in an easy-to-find spot for quick reference. Use clearly printed labels with colors. Signs, tags, and tickets should follow the same basic colors.
