NIOSH IDLH525 mg/m3
NIOSH REL: (nitriles) 2 ppm, Ceiling Concentration, not
to be exceeded in any 15-minute work period. | | First aid | If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
Medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately. If
this chemical has been inhaled, remove from exposure, begin
rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medi-
cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. | | Shipping | UN3276 Nitriles, liquid, toxic, n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required, Potential Inhalation Hazard (Special
Provision 5). | | Incompatibilities | Oxidizing agents, such as perchlorates,
peroxides, and permanganates. Nitriles may polymerize in
the presence of metals and some metal compounds. They
are incompatible with acids; mixing nitriles with strong
oxidizing acids can lead to extremely violent reactions.
Nitriles are generally incompatible with other oxidizing
agents such as peroxides and epoxides. The combination of
bases and nitriles can produce hydrogen cyanide. Nitriles
are hydrolyzed in both aqueous acid and base to give car-
boxylic acids (or salts of carboxylic acids). These reactions
generate heat. Peroxides convert nitriles to amides. Nitriles
can react vigorously with reducing agents. Acetonitrile and
propionitrile are soluble in water, but nitriles higher than
propionitrile have low aqueous solubility. They are also
insoluble in aqueous acids
