SCBAF:PD,PP (any self-contained breathing
apparatus that has a full facepiece and is operated in a pressure-demand or
other positive-pressure mode) SAF:PD,PP:ASCBA (any supplied-air respirator that
has a full facepiece and is operated in a pressure-demand or other

(any air-purifying, full-facepiece respirator with a high-efficiency
particulate filter) SCBAE (any appropriate escape-type, self-contained
breathing apparatus).
Reactivity:
Contact
with ammonia forms a shocksensitive compound. Reaction with aluminum can be
violent.
FIRE INFORMATION
Noncombustible
solid. If material or contaminated runoff enters waterways, notify downstream
users of potentially contaminated water.
FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Administer oxygen if breathing is difficult. Remove
and isolate contaminated clothing and shoes. case of contact with substance,
immediately flush skin or eyes with running water for at least 20 minutes.
Ensure that medical personnel are aware of the material(s) involved, and take
precautions to protect themselves.
