OSHA 30 Hour Construction Program Practice Test

Which color combination is required for directional signs in construction sites?

1. Red with white symbols

2. White with a black panel

3. Green with yellow symbols

4. Blue with white symbols

The correct answer is: White with a black panel

The required color combination for directional signs in construction sites is white with a black panel. This standard is established to ensure high visibility and clarity for individuals navigating around potentially hazardous areas. Directional signs are critical for guiding workers and visitors safely, indicating paths to follow, and informing about entrances or exits. The use of white backgrounds with black lettering or symbols increases contrast, making it easier for individuals to read the sign from a distance or while moving. This contrast is essential in a bustling construction environment, where distractions and varying lighting conditions can make signs harder to see. Other options, while they may represent various meanings in sign-making or safety communication, do not conform to the specific requirements for directional signage as outlined by OSHA standards and guidelines. Each of those color combinations may be suited for other applications, such as warning signs or informational signs, but they do not fulfill the criteria for directional guidance in a construction context.
