Potential Health Effects
----------------------------------
Inhalation:
Inhalation of vapors causes irritation to the respiratory tract. High
concentrations can cause narcosis, headache, fatigue, chest pains, cough,
nausea, dizziness, and possible damage to liver and kidneys.
Ingestion:
May be absorbed through the gastrointestinal tract; symptoms may parallel
inhalation. Additional symptoms may include vomiting, stomach pain.
Skin Contact:
May cause irritation, redness, and pain. Liquid degreases the skin.
Eye Contact:
Vapors > 300 ppm cause burning sensations in the eyes. Contact causes
irritation, redness, and pain.
Chronic Exposure:
Prolonged or repeated skin exposure may cause dermatitis. Chronic exposure may
cause eye effects.
Aggravation of Pre-existing Conditions:
Use of alcoholic beverages may enhance toxic effects.
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 soap and 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:
Flash point: 38C (100F) CC
Autoignition temperature: 379C (714F)
Flammable limits in air % by volume:
lel: 1.1; uel: 7.5
Flammable Liquid and Vapor! Contact with strong oxidizers may cause fire.
(Flash point and Auto Ignition values for the mixed isomer.)
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits
noted above. Vapors can flow along surfaces to distant ignition source and
flash back. Sealed containers may rupture when heated.
Fire Extinguishing Media:
Dry chemical, alcohol foam 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.
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! Have dry powder fire extinguisher on hand during clean-up operations.
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. 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.
J. T. Baker SOLUSORB(R) 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 n-Amyl Acetate:
- OSHA Permissible Exposure Limit (PEL):
100 ppm (TWA).
for Pentyl Acetate, all isomers:
- ACGIH Threshold Limit Value (TLV):
50 ppm (TWA), 100 ppm (STEL)
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-face organic vapor 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 organic vapor 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-face piece
positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators
do not protect workers in oxygen-deficient atmospheres. Where respirators are
required, you must have a written program covering the basic requirements in
the OSHA respirator standard. These include training, fit testing, medical
approval, cleaning, maintenance, cartridge change schedules, etc. See
29CFR1910.134 for details.
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.
