Potential Health Effects
----------------------------------
The health effects from exposure to diluted forms of this chemical are not
well documented. They are expected to be less severe than those for
concentrated forms which are referenced in the descriptions below.
Inhalation:
Respiratory tract irritant, may cause serious burns on acute contact.
Severe injury is usually avoided by the self-limiting coughing and sneezing
symptoms.
Ingestion:
Toxic! Corrosive to mucous membranes and may cause perforation of the
esophagus and stomach. Abdominal pain, nausea, vomiting, general
gastro-intestinal upset can be expected.
Skin Contact:
Irritant, possibly corrosive if contact is prolonged. Soreness, redness,
destruction of skin may result.
Eye Contact:
Irritant, possibly corrosive to eye tissues. Tearing, redness, pain,
impaired vision are symptoms.
Chronic Exposure:
Development of a defatting dermatitis on prolonged contact with potassium
hydroxide has been reported. Continued irritation may lead to increased
susceptibility to respiratory illness.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired
kidney or respiratory function may be more susceptible to the effects of
the substance.
4. First Aid Measures
First aid procedures given apply to concentrated solutions. Exposures to
dilute solutions may not require these extensive first aid procedures.
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never
give anything by mouth to an unconscious person. Get medical attention
immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical attention
immediately. 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:
Sealed containers may rupture when heated.
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
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. Store in a cool, dry, ventilated area.
Protect against physical damage. Separate from acids and alkalis. Protect
from freezing. Containers of this material may be hazardous when empty
since they retain product residues (vapors, liquid); observe all warnings
and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
For Potassium Hydroxide [1310-58-3]:
- ACGIH Threshold Limit value (TLV):
2 mg/m3 Ceiling
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 P95 or R95
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 P100 or R100 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.
Please note that N filters are not recommended for this material. 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 a full face shield where splashing is
possible. Maintain eye wash fountain and quick-drench facilities in work
area.
