MATERIALS HAZARD RATING CODE

ACSS uses the National Fire Protection Association system to identify the different levels of hazards that

are caused by the use of a given material. A Hazard Code identifies three effects of a material on a

person: health (eat, drink, touch, and breathe), fire (when and how it burns), and reactivity (chemical

explosions). Also, each material is given a storage group for safety.

Each code has three numbers and one letter (for example, 130D) as shown in the Hazard Code symbol

below. The three numbers show the hazard levels for health, fire, and reactivity, in that sequence. The

range of each number is 0 to 4. The higher the number, the more dangerous the hazard. You must be

careful with any material that has a Hazard Code with a 2, 3, or 4. The one letter (A thru E) in the code

identifies a specific storage group that is applicable for the material.

If applicable, materials used for the procedures in this manual are given a Hazard Code. More data on

the health and fire levels is shown on page H-2. Get specific data on a material from the data sheet

supplied by the manufacturer of the material.
