Sign Classification and sign Requirements

OSHA has three classifications of signs:

1. Danger Signs — Indicate immediate danger and that special precautions are necessary. OSHA specifies that red, black and white colors are to be used for danger signs.

2. Caution Signs — Warn against potential hazards or caution against unsafe practices. OSHA specifies that caution signs must have a yellow background and black panel with yellow letters. All letters used against the yellow background must be black.

3. Safety Signs— Must be used where there is a need for general instructions and suggestions relative to safety measures. OSHA specifies that safety instruction signs (OSHA Signs) must have a white background, green panel and white letters. Any letters used on the white background must be black.

ANSI has five different types of signs:

1. Danger Signs - These are used for hazardous situations to prevent serious injury or death. These signs have a red background with white text and should be reserved for the most dangerous hazards within the facility.

2. Warning Signs - These signs have black text with an orange background. This means serious hazard that could also result in injury or death.

3. Caution Signs - Black text with a yellow background that could be a sign of potential modeterate injury. An example is a "Slippery when wet" sign.

4. Notice Signs - The blue sign with white text are to convey other information not related to safety when there is no hazard present. An example might be "No Smoking" signs around flammable fluids.

5. Safety instruction signs - Green background with white text that is informational such as First Aid Signs.
