Safety Talks – Safety Signage
Safety Color Coding for marking physical hazards and Accident Prevention Signs is a standard way to identify hazards and visually communicate information. In the workplace where hazards are present, safety signs and colors are useful tools to help identify health and safety hazards, provide safety instructions, show where emergency equipment is located, and tell what type of personal protective equipment must be worn to access an area.
Safety signs are color coordinated – each color represents a specific type of warning. They contain signal words intended to capture a person’s immediate attention. It is important that you review the safety colors with employees so they can recognize and understand the different hazard warnings.
