Potential Health Effects
----------------------------------

Inhalation:
Inhalation can cause a flu-like illness (metal
fume fever). This 24- to 48-hour illness is characterized by chills, fever,
aching muscles, dryness in the mouth and throat and headache. May irritate the
respiratory tract. May increase the incidence of upper respiratory infections
(pneumonia). Absorption of inorganic manganese salts through the lungs is poor
but may occur in chronic poisoning.
Ingestion:
May cause
abdominal pain and nausea. Although they are poorly absorbed through the
intestines, inorganic manganese salts may produce hypoglycemia and decreased
calcium blood levels should absorption occur.
Skin Contact:
May
cause irritation with redness and pain.
Eye Contact:
May cause
irritation, redness and pain.
Chronic Exposure:
Chronic
manganese poisoning can result from excessive inhalation and ingestion
exposure and involves impairment of the central nervous system. Early symptoms
include sluggishness, sleepiness, and weakness in the legs. Advanced cases
have shown fixed facial expression, emotional disturbances, spastic gait, and
falling. Illness closely resembles Parkinson's Disease. Kidney effects, blood
changes and manganese psychosis also may occur as a result of chronic
exposure. Chronic inhalation exposure can cause lung damage.

Aggravation of Pre-existing Conditions:
Persons with impaired
respiratory function, psychiatric or neurological disturbances, and
nutritional deficiencies may be more susceptible to the effect of this
substance.

4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
Induce vomiting immediately as directed
by medical personnel. Never give anything by mouth to an unconscious person.
Get medical attention.
Skin Contact:
Immediately flush skin
with plenty of water for at least 15 minutes. Remove contaminated clothing and
shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get
medical attention if irritation develops.
Eye Contact:

Immediately flush eyes with plenty of water for at least 15 minutes,
lifting upper and lower eyelids occasionally. Get medical attention if
irritation persists.

5. Fire Fighting Measures

Fire:
Not considered to be a fire hazard.

Explosion:
Not considered to be an explosion hazard.

Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special Information:
In the
event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated in the
pressure demand or other positive pressure mode.

6. Accidental Release Measures

Ventilate area of leak or spill. Keep unnecessary and unprotected
people away from area of spill. Wear appropriate personal protective equipment
as specified in Section 8. Spills: Pick up and place in a suitable container
for reclamation or disposal, using a method that does not generate dust. US
Regulations (CERCLA) require reporting spills and releases to soil, water and
air in excess of reportable quantities. The toll free number for the US Coast
Guard National Response Center is (800) 424-8802.

7. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. Containers of this material
may be hazardous when empty since they retain product residues (dust, solids);
observe all warnings and precautions listed for the product.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
- OSHA Permissible Exposure
Limit (PEL):
5 mg/m3 Ceiling for manganese compounds as Mn

- ACGIH
Threshold Limit Value (TLV):
0.2 mg/m3 (TWA) for manganese, elemental and
inorganic compounds as Mn
Ventilation System:
A system of local
and/or general exhaust is recommended to keep employee exposures below the
Airborne Exposure Limits. Local exhaust ventilation is generally preferred
because it can control the emissions of the contaminant at its source,
preventing dispersion of it into the general work area. Please refer to the
ACGIH document, Industrial Ventilation, A Manual of Recommended
Practices, most recent edition, for details.
Personal Respirators
(NIOSH Approved):
If the exposure limit is exceeded and engineering
controls are not feasible, a half facepiece particulate respirator (NIOSH type
N95 or better filters) may be worn for up to ten times the exposure limit or
the maximum use concentration specified by the appropriate regulatory agency
or respirator supplier, whichever is lowest.. A full-face piece particulate
respirator (NIOSH type N100 filters) may be worn up to 50 times the exposure
limit, or the maximum use concentration specified by the appropriate
regulatory agency, or respirator supplier, whichever is lowest. If oil
particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use
a NIOSH type R or P filter. For emergencies or instances where the exposure
levels are not known, use a full-facepiece positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect workers in
oxygen-deficient atmospheres.
Skin Protection:
Wear protective
gloves and clean body-covering clothing.
Eye Protection:
Use
chemical safety goggles. Maintain eye wash fountain and quick-drench
facilities in work area.
