2101 I/O Plus Display Components Maintenance Manual
Revision B
March 15, 2009 Use or disclosure of information on this page is subject to the
restrictions of the Proprietary Notice on page TITLE-2 of this document.
This manual uses the National Fire Protection Association system to identify the different levels of hazards caused by
the use of a given material. A Hazard Code identies three effects of a material on a person: health (eat, drink, touch,
and breathe), re (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, re, 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 letter (A thru E) in the code identies a specic 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
re levels is shown on page H-2. Get specic data on a material from the data sheet supplied by the manufacturer of the
material.
