HEALTH & SAFETY INFORMATION
• IDLH:
500
mg[Mn]/m3
•
Contact causes tissue burns, and stains the skin dark rown. Eye contact can
cause serious damage. Ingestion causes severe distress of gastrointestinal
system. May be fatal if more than 4 oz. are consumed. Long term or repeated
exposures may cause genetic changes in living cells; lung problems.
Exposure Limits:
•
ACGIH TLV: TWA 0.2 mg[Mn]/m3, inorganic compounds
•
OSHA PEL: 5 mg[Mn]/m3 ceiling limit (compounds & fume)
•
NIOSH: 1 mg[Mn]/m3 TWA; 3 mg[Mn]/m3 STEL
•
DFG MAK: 5 mg[Mn]/m3 (compounds & fume)
Respirator:
as
manganese compound

10 mg/m3:
DMXSQ if not present as a fume (any dust and
mist respirator except single-use and quarter mask respirators) SA (any
supplied-air respirator).
25
mg/m3:
SA:CF (any
supplied-air respirator operated in a continuous-flow mode.) PAPRDM if not
present as a fume (any powered, air-purifying respirator with a dust and mist
filter).
50 mg/m3:
HiEF (any airpurifying, full-facepiece
respirator with a highefficiency particulate filter) SAT:CF (any suppliedair
respirator that has a tight-fitting facepiece and is operated in a
continuous-flow mode) PAPRTHiE (any powered, air-purifying respirator with a
tightfitting facepiece and a high-efficiency particulate filter) SCBAF (any
self-contained breathing apparatus with a full facepiece) SAF (any supplied-air
respirator with a full facepiece).
500
mg/m3:
SA:PD:PP (any
supplied-air respirator operated in a pressure-demand or other
positive-pressure mode).
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 positivepressure mode) SAF:PD,PP:ASCBA (any suppliedair respirator that
has a full facepiece and is operated in a pressure-demand or other
positive-pressure mode in combination with an auxiliary self-contained
reathing
apparatus
operated in a pressure-demand or other positive-pressure mode.
Escape:
HiEF
(any airpurifying, full-facepiece respirator with a highefficiency particulate
filter) SCBAE (any appropriate escape-type, self-contained breathing
apparatus).
Reactivity:
A
powerful oxidizer. Forms heat- and shock-sensitive compound with sulfuric acid.
Reacts violently with combustibles or reducing agents. It will decompose, and
release oxygen if brought into contact with alcohol acids, ferrous salts,
iodides, and oxalates. Reacts explosively or initiates fire if brought into
contact with acetic acid, acetic anhydride, anhydrous ammonia, antimony,
arsenic, hydrogenperoxide, hydroxylamine, hydrogen trisulfide, glycerine,
ethylene glycol, hydroxylamine, organic matter, polypropylene, phosphorus,
powdered sulfur, and finely divided combustible material, etc. Incompatible
with nitric acid, producing toxic chlorine fumes. A dangerous fire and
explosion hazard; isolate from all other materials. Slowly decomposes with
time.
FIRE INFORMATION: Hazard Classifications:
Not
flammable, but it is powerful oxidizer and a fire hazard. Decomposes at 464°F
(240°C) and releases oxygen; which will greatly intensify an ongoing fire. 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,
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.
