Potential Health Effects
----------------------------------
Inhalation:
A slight irritant to the mucous membranes. Toxic effects exerted upon
nervous system, particularly the optic nerve. Once absorbed into the body,
it is very slowly eliminated. Symptoms of overexposure may include
headache, drowsiness, nausea, vomiting, blurred vision, blindness, coma,
and death. A person may get better but then worse again up to 30 hours
later.
Ingestion:
Toxic. Symptoms parallel inhalation. Can intoxicate and cause blindness.
Usual fatal dose: 100-125 milliliters.
Skin Contact:
Methyl alcohol is a defatting agent and may cause skin to become dry and
cracked. Skin absorption can occur; symptoms may parallel inhalation
exposure.
Eye Contact:
Irritant. Continued exposure may cause eye lesions.
Chronic Exposure:
Marked impairment of vision has been reported. Repeated or prolonged
exposure may cause skin irritation.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired liver
or 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. Get medical attention immediately.
Ingestion:
Induce vomiting immediately as directed by medical personnel. 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. 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: 12C (54F) CC
Autoignition temperature: 464C (867F)
Flammable limits in air % by volume:
lel: 6.0; uel: 36
Flammable Liquid and Vapor!
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits
noted above. Moderate explosion hazard and dangerous fire hazard when
exposed to heat, sparks or flames. Sensitive to static discharge.
Fire Extinguishing Media:
Use alcohol foam, dry chemical or carbon dioxide. (Water may be
ineffective.)
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. Use water spray to blanket
fire, cool fire exposed containers, and to flush non-ignited spills or
vapors away from fire. Vapors can flow along surfaces to distant ignition
source and flash back.
6. Accidental Release Measures
Ventilate area of leak or spill. Remove all sources of ignition. Wear
appropriate personal protective equipment as specified in Section 8.
Isolate hazard area. Keep unnecessary and unprotected personnel from
entering. Contain and recover liquid when possible. Use non-sparking tools
and equipment. Collect liquid in an appropriate container or absorb with an
inert material (e. g., vermiculite, dry sand, earth), and place in a
chemical waste container. Do not use combustible materials, such as saw
dust. Do not flush to sewer! If a leak or spill has not ignited, use water
spray to disperse the vapors, to protect personnel attempting to stop leak,
and to flush spills away from exposures. US Regulations (CERCLA) require
reporting spills and releases to soil, water and air in excess of
reportable quantities. The toll free number for the US Coast Guard National
Response Center is (800) 424-8802.
J. T. Baker SOLUSORB®
solvent adsorbent is recommended for spills of this product.
7. Handling and Storage
Protect against physical damage. Store in a cool, dry well-ventilated
location, away from any area where the fire hazard may be acute. Outside or
detached storage is preferred. Separate from incompatibles. Containers
should be bonded and grounded for transfers to avoid static sparks. Storage
and use areas should be No Smoking areas. Use non-sparking type tools and
equipment, including explosion proof ventilation. 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. Do Not attempt to clean empty containers since residue is
difficult to remove. Do not pressurize, cut, weld, braze, solder, drill,
grind or expose such containers to heat, sparks, flame, static electricity
or other sources of ignition: they may explode and cause injury or death.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
For Methyl Alcohol:
- OSHA Permissible Exposure Limit (PEL):
200 ppm (TWA)
- ACGIH Threshold Limit Value (TLV):
200 ppm (TWA), 250 ppm (STEL) skin
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. Use
explosion-proof equipment.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not
feasible, wear a supplied air, full-facepiece respirator, airlined hood, or
full-facepiece self-contained breathing apparatus. Breathing air quality
must meet the requirements of the OSHA respiratory protection standard
(29CFR1910.134). This substance has poor warning properties.
Skin Protection:
Rubber or neoprene gloves and additional protection including impervious
boots, apron, or coveralls, as needed in areas of unusual exposure.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench
facilities in work area.
