Schedule 1: 3 Interchanging and Combining Signs

The document provides guidelines for safety signs and signals. It discusses acceptable substitutes for safety signs, including illuminated signs, acoustic signals, verbal communication, and hand signals. It also notes signs that can be used together, such as illuminated signs and acoustic signals. The document then describes standard color-coding for safety signs - red for prohibition/danger, yellow or amber for warnings, blue for mandatory actions, and green for emergency exits or no danger. It concludes by listing factors that could reduce the effectiveness of signs, such as too many signs close together or using conflicting illuminated or acoustic signals simultaneously.
