4.First-aid measures

4.1 Description of necessary first-aid measures

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.

In case of skin contact

Wear protective gloves when administering first aid. First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer immediately for medical attention.

In case of eye contact

Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.

If swallowed

Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

4.2 Most important symptoms/effects, acute and delayed

Inhalation of fumes results in coughing and choking sensation, and irritation of nose and lungs. Liquid causes burns. (USCG, 1999)

Gas concentrations of 50 to 100 ppm are tolerable for 1 hour. Concentrations of 1,000 to 2,000 ppm are dangerous, even for brief exposures. More severe exposures will result in serious respiratory distress and prolonged exposures will result in death. Mists of hydrochloric acid are considered less harmful than anhydrous hydrochloric acid, because droplets have no dehydrating action. Individuals with respiratory problems and digestive diseases may be adversely affected by low level exposures to the gas or mist. (EPA, 1998)

Excerpt from ERG Guide 125 [Gases - Corrosive]: TOXIC; may be fatal if inhaled, ingested or absorbed through skin. Vapors are extremely irritating and corrosive. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution. (ERG, 2016)

SYMPTOMS: Symptoms of exposure to this compound include mild irritation of the skin and eyes, diarrhea and gastrointestinal irritation. It may also cause nausea, pulmonary edema and coma. Gastrointestinal disturbances may occur. ACUTE/CHRONIC HAZARDS: This compound is a mild irritant of the skin and eyes. When heated to decomposition it emits toxic fumes of nitrogen oxides, sulfur oxides and ammonia.

4.3 Indication of immediate medical attention and special treatment needed, if necessary

/PREHOSPITAL/ Consult with the base station physician or the regional poison control center for advice regarding triage of multiple victims. Patients with evidence of significant exposure such as skin or eye irritation, pain, or breathing difficulties should be transported to a medical facility for evaluation. Others may be discharged from the scene after their names, addresses, and telephone numbers are recorded. Those discharged should be advised to seek medical care promptly if symptoms develop

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.

5.2 Specific hazards arising from the chemical

Special Hazards of Combustion Products: Toxic and irritating vapors are generated when heated. (USCG, 1999)

Fire may produce irritating or poisonous gases. Containers may explode in heat of fire. At high temperatures, it decomposes into hydrogen and chlorine. The following materials should be avoided: Mercuric sulfate -- violent reaction with gaseous hydrochloric acid at 250F. Sodium -- reacts vigorously with gaseous hydrochloric acid. Acetic anhydride, 2-aminoethanol, ammonium hydroxide, chlorosulfonic acid, ethylene diamine, ethyleneimine, oleum, propiolactone, sodium hydroxide, sulfuric acid, and vinyl acetate -- increase in temperature and pressure when mixed with hydrochloric acid. Calcium phosphide -- energetic reaction with hydrochloric acid. Silver perchlorate and carbon tetrachloride -- when mixed in combination with hydrochloric acid forms a compound that detonates at 105F. Formaldehyde -- when mixed with hydrochloric acid forms a human carcinogen. Material reacts violently with bases and is corrosive with the generation of heat. Reacts with base metals, forming combustible gas (hydrogen). Reacts violently with strong oxidants forming toxic gas (chlorine). Avoid heat; at high temperatures it will decompose into hydrogen and chlorine. (EPA, 1998)

Excerpt from ERG Guide 125 [Gases - Corrosive]: Some may burn but none ignite readily. Vapors from liquefied gas are initially heavier than air and spread along ground. Some of these materials may react violently with water. Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. For UN1005: Anhydrous ammonia, at high concentrations in confined spaces, presents a flammability risk if a source of ignition is introduced. (ERG, 2016)

This chemical is probably combustible.

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

Section XII.        Ecological Information    
    Ecotoxicity        Not available.    
    Environmental Fate        (Diethyl Ether)    
    Diethyl ether's production and use as a solvent, in the manufacture of gun powder, and as a primer for gasoline engines
    may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 538 mm
    Hg at 25 deg C indicates diethyl ether will exist solely as a vapor in the ambient atmosphere. Vapor-phase diethyl ether
    will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and nitrate radicals;
    half-lives for these reactions in air are estimated to be 1.2 and 5.8 days, respectively. Direct photolysis is not expected to
    be an important removal process since aliphatic ethers do not absorb light in the environmental spectrum. If released to
    soil, diethyl ether is expected to have high mobility based upon an estimated Koc of 73. Volatilization from moist soil
    surfaces is expected to be an important fate process based upon a Henry's Law constant of 1.23X10-3 atm-cu m/mole.
    Diethyl ether is expected to volatilize from dry soil surfaces based upon its vapor pressure. Aqueous screening studies
    indicate biodegradation is expected to be a slow fate process in both soil and water; 0 to 1.1% BODT was observed over a
    period of 5 days. If released into water, diethyl ether is not expected to adsorb to suspended solids and sediment in water
    based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon
    this compound's Henry's Law constant. Estimated volatilization half-lives from a model river and model lake are 3.1 hours
    and 3.6 days, respectively. BCFs ranging from 0.9 to 9.1 in carp suggest bioconcentration in aquatic organisms is low.
    Hydrolysis is not expected to occur due to the lack of hydrolyzable functional groups. Occupational exposure to diethyl
    ether may occur through inhalation and dermal contact with this compound at workplaces where diethyl ether is produced
    or used. The general population may be exposed to diethyl ether from consumer products, inhalation of ambient air, and
    ingestion of contaminated drinking water.

Section XIII. Disposal Considerations
    Waste Disposal        Recycle to process, if possible. Consult your local regional authorities. You may be able to dissolve or mix material with a    
    combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber system. Observe all
    federal, state and local regulations when disposing of the substance.
