-----------------------------------------------------------------------------------------------------------
Potential Health Effects
----------------------------------
Exposure may result in intense burning of the eyes, nose, throat, lungs and
skin. Experimental studies have indicated that TMAH is a weak inhibitor of
acetylcholinesterase and acts as a cholinergic (muscarinic and nicotinic)
agonist. Depending on the level and duration of exposure, signs and symptoms
may include blurred or double vision; pinpoint pupils; changes in heart rate
and blood pressure; abdominal cramping, nausea and vomiting; diarrhea,
excessive salivation sweating or bronchial secretions; urinary incontinence;
muscle twitching, tremors or convulsions. Other symptoms consistent with
cholinergic activity may also be observed.
Inhalation:
Inhalation of alkaline vapors can produce upper airway edema, respiratory
failure, wheezing, pulmonary edema, and pnemonitis.
Ingestion:
Alkaline corrosive ingestion may produce burns to the lips, tongue, oral
mucosa, upper airway, esophagus and occasionally stomach.
Skin Contact:
Dermal contact with alkaline corrosives may produce pain, redness, severe
irritation or full thickness burns. May be absorbed through the skin with
possible systemic effects.
Eye Contact:
Alkaline eye exposures produce severe irritation with effects similar to those
of dilute caustics. Inflammation or burns with possible damage to the eye
tissues can occur together with tearing and considerable pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired
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 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:
Flash point: > 94C (> 201F) CC
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. Keep unnecessary and unprotected people away from area
of spill. Wear appropriate personal protective equipment as specified in
Section 8. Contain and recover liquid when possible. Do not flush caustic
residues to the sewer. Residues from spills can be diluted with water,
neutralized with dilute acid such as acetic, hydrochloric or sulfuric. Absorb
neutralized caustic residue on clay, vermiculite or other inert substance and
package in a suitable container for disposal.
7.
Handling and Storage
Keep in a
tightly closed container. Store in a cool, dry, corrosion-proof, ventilated
area away from moisture, sources of heat or ignition, combustibles and
oxidizers. Protect against physical damage. 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:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures as low as possible. 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):
For conditions of use where exposure to the substance is apparent and
engineering controls are not feasble, consult an industrial hygienist. 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.
