--------------------------------------- ------------ ------------ ---------
Manganese Carbonate 598-62-9 90 - 100% Yes
Inhalation: Acute poisoning can occur from excessive inhalation causing
symptoms noted under Chronic Exposure.
Ingestion: Extremely large oral dosages may produce gastrointestinal
disturbances and acute poisoning as noted under Chronic Exposure.
Skin Contact: No adverse effects expected.
Eye Contact: No adverse effects expected but dust may cause mechanical
irritation.
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 pre-existing skin
disorders or eye problems or impaired respiratory function may be more
susceptible to the effects of the substance. A nutritional iron deficiency
leaves the body more susceptible to manganese build-up.
Inhalation: Remove to fresh air. Get medical
attention for any breathing difficulty.
Ingestion: If large amounts were swallowed, give water to drink and get
medical advice.
Skin Contact: Wash exposed area with soap and water. Not expected to
require first aid measures.
Eye Contact: Wash thoroughly with running water. Get medical advice if
irritation develops.
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.
Clean-up personnel require protective clothing and respiratory protection from dust. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Material discolors on contact with air. Isolate from incompatible substances. 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.
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.
Appearance: Fine, pink, light brown powder.
Odor: Odorless.
Solubility: Insoluble in water.
Density: 3.125
pH: No information found.
% Volatiles by volume @ 21C (70F): 0
Boiling Point: Not applicable.
Melting Point: > 200C (> 392F)
Vapor Density (Air=1): No information found.
Vapor Pressure (mm Hg): No information found.
Evaporation Rate (BuAc=1): No information found.
Stability: Stable under ordinary conditions of use
and storage. Discolors slowly in air. Slowly decomposes in air to manganous
oxide with evolution of carbon dioxide gas.
Hazardous Decomposition Products: At higher temperatures (7300C) forms
manganous oxides, carbon dioxide and carbon monoxide.
Hazardous Polymerization: Will not occur.
Incompatibilities: Contact with acids may generate carbon dioxide gas.
Oxidizes toxic sulfur dioxide to the more toxic sulfur trioxide and causes
violent decomposition of hydrogen peroxide.
Conditions to Avoid: Excessive dust generation. Incompatibles.
No LD50/LC50 information found relating to normal routes of occupational exposure.
