Other Comments: Chronic exposure to manganese may result in a central nervous system disorder
(manganism). Symptoms may include confusion, bizarre behavior, visual hallucinations, difficulty with speech
and movement, tremor, loss of balance, decreased libido and impotence.
Chronic exposure to high concentrations of iron have been associated with hemosiderosis, hemochromatosis
and in severe cases, liver cirrhosis. Typical occupational exposures to iron compounds are not expected to
cause these effects. Chronic inhalation can produce “mottling” of the lungs (siderosis). This is considered a
benign pneumoconiosis and does not normally lead to fibrosis or cause significant physiologic impairment.
5. FIRE FIGHTING MEASURES
Unusual Fire and Explosive Hazards: No unusual fire or explosive hazards are expected. However, dust
powder or fumes are flammable or explosive when exposed to heat or flames.
Extinguishing Media: For fires involving powder or dust, use dry chemicals, ,sand, earth, water spray or
regular foam.

Fire Fighting Instructions::For fires beyond the initial stage, emergency responders in the immediate hazard
area should wear protective clothing. When the potential chemical hazard is unknown, in enclosed or confined
spaces, or when explicitly required by DOT, a self-contained breathing apparatus should be worn. In addition,
wear other appropriate protective equipment as conditions warrant (see Section 8). Isolate immediate hazard
area and keep unauthorized personnel out. Stop spill/release if it can be done with minimal risk. Move
undamaged containers from immediate hazard area if it can be done with minimal risk. Water spray may be useful
in minimizing or dispersing vapors. Cool equipment exposed to fire with water, if it can be done with minimal risk.
Hazardous Combustion Products: Combustion may yield smoke, metal oxides and other products of
incomplete combustion.
6. ACCIDENTAL RELEASE MEASURES
Personal Precautions: In case of dust release, stay upwind and away from spill. Notify persons down-wind of
spill/release, isolate immediate hazard area and keep unauthorized personnel out. Contain spill if it can be
done with minimal risk. Wear appropriate protective equipment including respiratory protection as conditions
warrant (see Section 8). See Sections 2 and 7 for additional information on hazards and precautionary
measures.
Environmental Precautions: Prevent spilled material from entering sewers, storm drains, other unauthorized
treatment drainage systems, and natural waterways.
Methods for Containment and Clean-up: Notify relevant authorities in accordance with all applicable
regulations. Immediately clean-up of any spill is recommended. Sweep up and package appropriately for
disposal.
