MATERIALS HAZARD RATING CODE
AmSafe Inc. 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, the materials used for the procedures in this manual are given a Hazard Code. More data on
the health and fire levels is shown in on page 4. Get specific data on a material from the data sheet supplied
by the manufacturer of the material.
