Description

NFPA 704 is the standard that is intended to provide a simple, readily recognized, and easily understood system of markings. These markings will provide a general idea of the hazards of a material and the severity of these hazards as they relate to emergency response.

In more specific terms the objectives of the system are to:

• To provide an appropriate signal or alert and on-the-spot information to safeguard the lives of both public and private emergency response personnel
• To assist in planning for effective fire and emergency control operations, including cleanup
• To assist all designated personnel, engineers, and plant and safety personnel in evaluating hazards

The system shall also enable fire-fighting, emergency, and other personnel to easily decide whether to evacuate the area or to commence emergency control procedures. It shall also assist those personnel in selecting fire-fighting tactics and emergency procedures.

Where do I need to post NFPA 704 signs?

Signs shall be in locations approved by the authority having jurisdiction and as a minimum shall be posted at the following locations:

• Two exterior walls or enclosures containing a means of access to a building or facility
• Each access to a room or area
• Each principal means of access to an exterior storage area
