Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory
tract. Symptoms may include coughing, shortness of breath. May cause headache,
dyspnea, and fever. May
also cause tracheobronchial irritation
and pulmonary edema.
Ingestion:
Causes irritation to the gastrointestinal
tract. Large oral doses may cause dizziness intense thirst, abdominal pain,
vomiting, and shock. Death
may occur from renal failure. Chromium
compounds in the 3+ state have a much lower toxicity than those in the
6+ state.
Skin Contact:
Causes irritation to skin. Symptoms
include redness, itching, and pain. Prolonged contact may cause skin ulcerations.
Eye Contact:
Causes irritation, redness, and pain.
Prolonged contact may cause eye damage.
Chronic Exposure:
Prolonged or repeated skin exposure
may cause dermatitis. Prolonged or repeated inhalation of dust may cause
perforation of the nasal septum.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin conditions
or impaired respiratory function may be more susceptible to the effects
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
soap and 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 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:
Use protective clothing and breathing
equipment appropriate for the surrounding fire.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear
appropriate personal protective equipment as specified in Section 8. Spills:
Sweep up and containerize for
reclamation or disposal. Vacuuming or
wet sweeping may be used to avoid dust dispersal. 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. 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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
for Cr(III) compounds = 0.5mg/m3 (TWA) -ACGIH Threshold Limit Value (TLV):
for Cr(III) compounds =
0.5 mg/m3 (TWA), A4 - Not classifiable
as a human carcinogen
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 and/or full
face shield where dusting or splashing of solutions is possible. Maintain
eye wash fountain and
quick-drench facilities in work area.
