Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing,
shortness of breath. High concentrations can cause pulmonary edema.
Absorption through inhalation of dust can produce systemic effects
paralleling those from ingestion exposure.
Ingestion:
Irritant to mucous membrane; causes gastro-intestinal upset, and larger
doses can cause nausea, vomiting, fever, rashes. Reduces oxygen to body
organs (methemoglobinemia) causing the lips and skin to turn blue.
Exposure causes a breakdown of red blood cells, which can lead to kidney
damage. May affect bone marrow (aplastic anemia).
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain. May
cause burns to skin tissue upon contact.
Eye Contact:
Causes irritation, redness, and pain. May cause burns.
Chronic Exposure:
Chronic exposure may affect red blood cells which can have an effect on the
liver, kidney and other organs.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or impaired respiratory function
may be more susceptible to the effects of the 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. Get medical attention. Wash clothing
before reuse. Thoroughly clean shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes,
lifting lower and upper eyelids occasionally. Get medical attention
immediately.
5. Fire Fighting Measures
Fire:
Not combustible, but substance is a strong oxidizer and its heat of
reaction with reducing agents or combustibles may cause ignition. Contact
with oxidizable substances may cause extremely violent combustion.
Liberates toxic gases when involved in a fire.
Explosion:
Strong oxidants may explode when shocked, or if exposed to heat, flame, or
friction. Also may act as initiation source for dust or vapor explosions.
Containers may explode when involved in a fire. Sensitive to mechanical
impact.
Fire Extinguishing Media:
Flood with large amounts of water.
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
Remove all sources of ignition. Ventilate area of leak or spill. Wear
appropriate personal protective equipment as specified in Section 8.
Spills: Clean up spills in a manner that does not disperse dust into the
air. Use non-sparking tools and equipment. Reduce airborne dust and prevent
scattering by moistening with water. Pick up spill for recovery or disposal
and place in a closed container.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage and moisture. Isolate from any source of
heat or ignition. Avoid storage on wood floors. Separate from
incompatibles, combustibles, organic or other readily oxidizable materials.
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):
15 mg/m3 total dust, 5 mg/m3 respirable fraction for nuisance dusts.
- ACGIH Threshold Limit Value (TLV):
10 mg/m3 total dust containing no asbestos and < 1% crystalline silica for
Particulates Not Otherwise Classified (PNOC).
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, a half-face dust/mist respirator 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 dust/mist respirator 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. 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 impervious protective clothing, including boots, gloves, lab coat,
apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench
facilities in work area.
