Potential Health Effects
----------------------------------
Inhalation:
Irritant. General anesthesia by inhalation can occur. Continued exposure
may lead to respiratory failure or death. Early symptoms include irritation
of nose and throat, vomiting, and irregular respiration, followed by
dizziness, drowsiness, and unconsciousness.
Ingestion:
Irritating to the mucous membranes. Ingestion of 1 or 2 ounces may be
fatal. Because of volatility the stomach becomes distended, which may
cause belching. Other symptoms can include vomiting, unconsciousness,
and coma.
Skin Contact:
Irritating to the skin and mucous membranes by drying effect. Can cause
dermatitis on prolonged exposure. May be absorbed through skin.
Eye Contact:
May cause irritation, redness and pain. Prolonged exposures to high
concentrations of vapor can cause eye damage.
Chronic Exposure:
Repeated exposures may be habit forming. Prolonged exposures may
result in headache, drowsiness, excitation, and psychic disturbances. The
ethyl alcohol component, in repeated high exposures, may cause damage
to the liver, blood and reproductive system. Teratogenic effects are
possible for ether and ethyl alcohol.
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
this substance. Alcoholic beverage consumption can enhance the toxic
effects of this substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician.
Ingestion:
DO NOT INDUCE VOMITING. Give large quantities of water. Never
give anything by mouth to an unconscious person. Call a physician
immediately.
Skin Contact:
Remove any contaminated clothing. Wash skin with soap or mild
detergent and water for at least 15 minutes. Call a physician.
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: -45C (-49F) CC
Autoignition temperature: 160C (320F)
Flammable limits in air % by volume:
lel: 1.9; uel: 36.0
Dangerous highly flammable liquid.
Explosion:
Containers may explode when involved in a fire. Above flash point,
vapor-air mixtures are explosive within flammable limits noted above.
May form explosive peroxides on long standing or after exposure to air or
light. May explode when brought in contact with nitric acid. Sensitivity to
mechanical impact: Yes, if peroxides are formed. Sensitive to static
discharge.
Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. Treat as a flammable gas in a fire
situation. Water spray may be used to keep fire exposed containers cool.
Water is ineffective as an extinguishing agent.
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. This highly flammable
liquid must be kept from sparks, open flame, hot surfaces, and all sources
of heat and ignition. Poisonous gases are produced in fire. Vapors are
heavier than air. Liquid floats on water. Both vapor and liquid may travel
to source of ignition 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庐 solvent adsorbent is recommended for spills of
this product.
7. Handling and Storage
Protect against physical damage. Outside or detached storage is preferred.
Inside storage should be in a standard flammable liquids storage room or
cabinet. Separate from oxidizing materials. Storage and use areas should
be No Smoking areas. Bond and ground containers when transferring
liquid. Isolate from other combustible material. Protect from direct
sunlight. Protect against static electricity and lightning for large quantity
storage rooms, protect with automatic sprinkler systems and total flooding
carbon dioxide systems. The reactivity hazard may be increased on
longstanding due to peroxide formation. Ether is subject to peroxide
formation in opened containers and should be protected from exposure to
air. When low peroxide ether is required, use only material from an
unopened can. Do not allow to evaporate to near dryness. Addition of
water or appropriate reducing agents will lessen peroxide formation. Any
ether remaining in opened containers that has not been consumed/used
after 2-3 days, should be discarded. Store At A Temperature Not
Exceeding 30C (86F).
DO NOT OPEN Unless Contents Are At Room Temperature (72F) or
Below For At Least 24 Hours. 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:
-OSHA Permissible Exposure Limit (PEL):
400 ppm (TWA) for ethyl ether
1000 ppm (TWA) for ethyl alcohol
-ACGIH Threshold Limit Value (TLV):
400 ppm (TWA) 500 ppm (STEL) for ethyl ether,
1000 ppm (TWA) for ethyl alcohol, A4
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. An organic vapor respirator is predicted to have a
short service life (less than 30 minutes at concentrations of ten times the
TLV/PEL) when used with this material.
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.
Other Control Measures:
Shoes should be conductive and nonsparking.
