HEALTH & SAFETY INFORMATION
•
Dust or fume may cause metal fume fever. Repeated exposure may cause chemical
to be collected in the body and cause upset stomach.
Respirator:
as
magnesium oxide 150 mg/m3:
DMFu
(any dust, mist and fume respirator) SA (any supplied-air respirator).
375 mg/m3:
SA:CF (any supplied-air respirator operated
in a continuous-flow mode) PAPRDMFu (any powered, air-purifying respirator with
a dust, mist, and fume filter).
750
mg/m3:
HiEF (any
air-purifying, full-facepiece respirator with a high-efficiency particulate
filter) PAPRHiE (any powered, air-purifying respirator with a high-efficiency
particulate filter) SCBAF (any selfcontained breathing apparatus with a full facepiece)
SAF (any supplied-air respirator with a full facepiece).
Emergency or Planned Entry into
Unknown Concentrations or IDLH Conditions
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 positivepressure mode in
combination with an auxiliary selfcontained breathing apparatus operated in a pressuredemand
or other positive-pressure mode).
Escape:
HiEF
(any air-purifying, full-facepiece respirator with a high-efficiency
particulate filter) SCBAE (any appropriate escape-type, self-contained
breathing apparatus).
Reactivity:
Strong
reducing agent; violent reaction with oxidizers, strong acids, carbon
tetrachloride, carbonates, chloroform, halogens, metal oxides, phosphates,
silver nitrate, sodium peroxide, sulfates, trichloroethylene, and many other
substances. In finely divided form, reacts with water and acids to release
flammablehydrogen gas.
FIRE INFORMATION:
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. In case of contact with substance,
wipe from skin immediately; flush skin or eyes with running water for at least
20 minutes. Keep victim warm and quiet. Ensure that medical personnel are aware
of the material(s) involved, and take precautions to protect themselves.
