OSHA Warning Signs

(57634)

An OSHA Warning Sign describes a hazardous situation that may lead to death or serious injury, but where the overall risk is not severe enough to need a Danger Header. Trained employees perceive and understand an orange and black sign as “Warning”. OSHA Warning Signs are used to mark a hazard level between “Danger” and “Caution”. For example - Parts of machinery or energized equipment that may cut, crush, or otherwise injure, inside of transmission guards for pulleys, gears, etc.

• Choose from a wide selection of warning signage in your choice of size, material and message.
• For custom warning sign, choose a template to personalize your own message. Pick a size, material, add text.
