TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking. NO contact with hot surfaces.
Alcohol-resistant foam. Powder. Carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


Inhalation Cough. Sore throat. Drowsiness. Vomiting. Headache. Laboured breathing. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness. Pain.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Dizziness. Drowsiness. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Remove all ignition sources. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: filter respirator for organic gases and vapours.)

DIETHYL ETHER ICSC: 0355
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
VERY VOLATILE, COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:
The substance can form explosive peroxides under the influence of light and air. Reacts violently with halogens, interhalogens, sulfur compounds and oxidants causing fire and explosion hazard. Attacks plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 400 ppm as TWA; 500 ppm as STEL (ACGIH 2001). EU OEL: 100 ppm (TWA); 200 ppm (STEL).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. The substance may cause effects on the central nervous system, resulting in narcosis.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the central nervous system. Caution, may cause addiction.
PHYSICAL PROPERTIES
Boiling point: 35C
Melting point: -116C
Relative density (water = 1): 0.7
Solubility in water, g/100 ml at 20C: 6.9
Vapour pressure, kPa at 20C: 58.6
Relative vapour density (air = 1): 2.6
Relative density of the vapour/air-mixture at 20C (air = 1): 1.9
Flash point: -45C c.c.
Auto-ignition temperature: 160-180C
Explosive limits, vol% in air: 1.7-48
Octanol/water partition coefficient as log Pow: 0.89
ENVIRONMENTAL DATA

NOTES
Use of alcoholic beverages enhances the harmful effect. Check for peroxides prior to distillation; eliminate if found.
