                                                ARSINE
             SECTION V       (continued)

                     quickly, depositing shiny black arsenic (*Merck 1983).

                 Incompatibility (Materials to Avoid):  Can react vigorously with oxidizing
                 materials.  May explode when exposed to chlorine, nitric acid, or potassium
                 plus ammonia (Sax 1984, p. 324; NIOSH/OSHA 1978, p. 48).

                 Hazardous Decomposition or Byproducts:      When heated to decomposition,
                 emits highly toxic fumes (Sax 1984, p. 324).

                 Hazardous Polymerization:    May Occur:  Not Found
                                              May Not Occur:    Not Found

                     Conditions to Avoid:    Not Found


             SECTION VI-- USE INFORMATION

                 This material is used in the manufacture of electronic components.  It may
                 be used in organic synthesis and as a poison gas for military purposes
                 (*SRI).


             SECTION VII-- PRECAUTIONS FOR SAFE HANDLING AND USE

             (Steps to be Taken in Case Material is Released or Spilled)
                 No flares, smoking, or flames in area.  Use water spray to reduce vapors.
                 Isolate area until arsine gas has dispersed.  Stay upwind; keep out of low
                 areas (*DOT 1984).  There is a high potential for generation of arsine
                 gas when inorganic arsenic is exposed to freshly-formed molecular hydrogen
                 (*Blackwell 1979).


             SECTION VIII-- PROTECTIVE EQUIPMENT FOR EMERGENCY SITUATIONS

                 For emergency situations, wear a positive pressure, pressure-demand,
                 full facepiece self-contained breathing apparatus (SCBA) or pressure-
                 demand supplied air respirator with escape SCBA and a fully-encapsulating,
                 chemical resistant suit.  See the introductory information section at the
                 beginning of the profiles for additional information.
