ADDITIONAL INFORMATION
AZIDE REACTS WITH MANY HEAVY METALS SUCH AS LEAD, COPPER, MERCURY,
SILVER, GOLD TO FORM EXPLOSIVE COMPOUNDS. COPPER AND LEAD AZIDES ARE
MORE SENSITIVE THAN NITROGLYCERINE. AZIDE REACTS WITH METAL HALIDES
TO GIVE A RANGE OF METAL AZIDE HALIDES, MANY OF WHICH ARE EXPLOSIVE.
INCOMPATIBLE WITH CHROMYL CHLORIDE, HYDRAZINE, BROMINE, CARBON
DISULFIDE, DIMETHYL SULFATE, DIBROMOMALONITRILE.
AN EXPLOSION OCCURRED WHEN A MIXTURE OF SODIUM AZIDE, METHYLENE
CHLORIDE, DIMETHYL SULFOXIDE, AND SULFURIC ACID WERE BEING
CONCENTRATED ON A ROTARY EVAPORATOR.
SECTION 8. - - - - - - EXPOSURE CONTROLS/PERSONAL PROTECTION- - - - - -
WEAR APPROPRIATE NIOSH/MSHA-APPROVED RESPIRATOR, CHEMICAL-RESISTANT
GLOVES, SAFETY GOGGLES, OTHER PROTECTIVE CLOTHING.
