Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing,
shortness of breath.
Ingestion:
Phosphates are slowly and incompletely absorbed when ingested, and seldom
result in systemic effects. Such effects, however, have occurred. Symptoms
may include vomiting, lethargy, diarrhea, blood chemistry effects, cardiac
effects and central nervous system effects. The toxicity of phosphates is
because of their ability to sequester calcium. Acute potassium intoxication
by mouth is rare because large single doses usually induce vomiting and
because in the absence of pre-existing kidney damage, potassium is rapidly
excreted. Potassium poisoning can result in heart effects, change in
respiration rate, tingling in the extremities, heaviness in the limbs,
nausea and diarrhea.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
May sequester calcium and cause calcium phosphate deposits in the kidneys.
Continued ingestion or absorption of phosphate and potassium can lead to
renal disorders and in acute cases, potassium poisoning. The latter can
involve circulatory complications, partial paralysis and ulcers of the
stomach.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired
liver, kidney or 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 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: Sweep up and containerize for
reclamation or disposal. Vacuuming or wet sweeping may be used to avoid
dust dispersal.
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 full facepiece respirator with
dust/mist filter 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.
