Signs, tags, and color codes are used on construction sites to warn employees of hazardous conditions and help them in case of an emergency. For signs to be effective they must be understood by the workforce they are trying to inform.
- RED - is the basic color used to inform workers of an immediate hazard. Most DANGER signs are red and white with white lettering on the red portion and black letters in the white area. Examples: DANGER - HIGH VOLTAGE, DANGER - KEEP OUT, DANGER - NO SMOKING. Red is also the color that identifies fire protection equipment and apparatus, safety cans, fire extinguishers and alarms. And of course there is the familiar red octagon with STOP in white letters.
- YELLOW - signs are messages of caution and warn you to take action to protect yourself. Caution signs are yellow with black lettering. Examples: CAUTION - WATCH YOUR STEP, CAUTION - LIVE POWER SUPPLY, CAUTION - EYE PROTECTION REQUIRED.
- ORANGE - the color used to identify dangerous machine parts. These are locations that can cause major lacerations, crushing injuries or electrical shock. For example, gears, pulleys and rollers may be marked with this color.
- Another sign is the SAFETY INSTRUCTION SIGN. These signs give you various kinds of safety information. The signs have a white background with a green panel that has white lettering. Example: This project has worked _ days without a lost time accident.
- Some of the common signs we are required to provide for work areas are: falling object, laser in use, confined space, open hole (RMF), pipe/wire pulls and hot work in progress.
