Potential Health Effects
----------------------------------
Inhalation: Causes irritation to the respiratory tract. Symptoms may
include coughing, shortness of breath.
Ingestion: Causes irritation to the gastrointestinal tract. Symptoms may
include nausea, vomiting and diarrhea.
Skin Contact: Causes irritation to skin. Symptoms include redness,
itching, and pain.
Eye Contact: Causes irritation, redness, and pain.
Chronic Exposure: Prolonged or repeated skin contact may produce severe
irritation or dermatitis.
Aggravation of Pre-existing Conditions: No information found.
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.
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.
Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8.
Spills: Pick up and place in a suitable container for reclamation or disposal in
a method that does not generate dust. Do not sweep. Damp mop any residue.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Do not store on wooden floors. 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):
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
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 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.
