Potential Health Effects
----------------------------------
Inhalation:
Inhalation of high concentrations of dust may
cause nasal or lung irritation.
Ingestion:
Large quantities can
produce gastrointestinal irritation and vomiting. May produce weakness and
circulatory problems. May affect heart. In severe cases, ingestion may be
fatal.
Skin Contact:
Contact may cause irritation or rash,
particularly with moist skin.
Eye Contact:
Potassium chloride
is moderate eye irritant. Redness, tearing, possible abrasion can occur.
Chronic Exposure:
No information found.
Aggravation of
Pre-existing Conditions:
Persons with impaired kidney 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.
Ingestion:
Induce vomiting immediately as directed by medical
personnel. Never give anything by mouth to an unconscious person. Call a
physician.
Skin Contact:
Remove any contaminated clothing. Wash
skin with soap and water for at least 15 minutes. Get medical attention if
irritation develops or persists.
Eye Contact:
In case of
contact, immediately flush eyes with plenty of water for at least 15 minutes,
lifting upper and lower eyelids occasionally. Call a physician if irritation
persists.
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:
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
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, using a method that does not
generate dust.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. 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 protective
gloves and clean body-covering clothing.
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.
