Diethyl Ether (DEE): Safety and Health Consideration
SAFETY AND HEALTH CONSIDERATIONS
The safety of working personnel in a chemical plant is of prime most considerations. The
principal ways in which chemicals may enter our body are-
For safety of every individual working in the plant one should not ignore the standard
procedures for operating the equipment. One should never take risks to save time and avoid
work and use of shortcuts or approximate readings. Safety of the workers as well as the
personnel safety depends upon the sincerity and accuracy of the operator. Safety should never
be compromise by anything. The loss of individual life can never be compromised by cash
profit. Hence during operation of a plant, safety should be prime importance.
The goal of chemical plant is not only to produce the chemicals, but to produce them safely. In
the plant’s operations, chainloss of control processes anywhere can lead to accidents and
losses of life and property from hazards. Attempts should be to prevent troubles from the
inspection, while designing, fabricating and operating.
Many chemicals can cause dangerous burns if they come in contact with tissues. Dehydration
by strong dehydrating, agents, digestion by strong acids and bases and oxidation by strong
oxidizing agents can destroy living tissues. Eyes Possible sources of fire are reduced by
eliminating all unnecessary ignition sources such as flames, sparks of heated, materials,
matches, smoking, welding, cutting static electricity, spontaneous combustion and non-
explosion proof electrical equipment are all potential ignition sources. Possible sources of fire

Safety in plant
There are primarily two types of major hazards in petrochemical industry:-
a) The first is due to flammability low flash point and wide explosive limits of the chemicals
b) Toxic hazard due to toxicity and carcinogenicity of various chemicals. Complete
understanding of the chemicals, their physical and chemical properties, especially with respect
to reactivity is very important for their safe handling.
Fire and Explosion Hazard
Careful plant layout and judicious choice of constructional material reduced the chance of this
hazard. Hazardous operation should be designed to meet the specification and codes.
Adequate venting is necessary and it is advisable to provide protection by using both spring
loaded values and rupture disks.
First aid measures
Ø Remove to fresh air.
Ø If not breathing, give artificial respiration.
Ø If breathing is difficult, give oxygen.
Ø Call a physician.
Ø If swallowed, do not induce vomiting.
Ø Give large quantities of water.
Ø Never give anything by mouth to an unconscious person.
Ø Get medical attention immediately.
Ø Aspiration hazard.
Ø In case of contact, immediately flush skin with plenty of soap and water for at least 15
minutes while removing contaminated clothing and shoes.
Ø Wash clothing before reuse.
Ø Call a physician.
Ø Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and
upper eyelids occasionally.
Ø Get medical attention immediately. 
Shipment and Handling
Ethanol and diethyl ether are both very flammable, and as such careful attention must be paid
to their transportation to and from and storage at the facility. Ethanol spontaneously combusts
at about 420°C. The reactors operate below this limit (250°C). It is very important to invest
in accurate and careful controllers to ensure that the temperatures in the Reactor never reach
this level. Measures should be taken to ensure that minute leaks in process equipment,
particularly the separation units which handle highly concentrated diethyl ether, can be
quickly detected and isolated.
Diethyl ether is hazardous, flammable, colorless liquid with a sweet, characteristic smell.
Diethyl ether stored in a pressure drums with an inhibitor such as 1-napthol to prevent
peroxide formation. It is stored in mild steel containers. Blanketing with nitrogen is
recommended but not essential. Tin plate cans, mild steel drums and aluminum containers are
suitable. Being heavier than air, ether vapor creeps along the ground. Therefore good
ventilation is necessary when it is handled to prevent the formation of ignitable mix. If glass
or plastic containers are used filling should be prepared by metallic pipeline that is below the
surface of ether or by placing ground chains or other metabolic conductors in the free flowing
ether to remove static electric charge.
Material safety data sheet (MSDS) of ethanol and diethyl ether is in appendix B.
