TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Risk of fire and explosion on contact with acid(s) and base(s).


EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Cough. Laboured breathing. Sore throat.
Ventilation. Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
•SKIN MAY BE ABSORBED! Dry skin. Redness. Pain. Swelling.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES Redness. Pain.
Face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION (See Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance polymerize with acids and bases with fire or explosion hazard. On combustion, forms acrid smoke and irritating fumes. Reacts with active hydrogen compounds (e.g., alcohols, amines).

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm as TWA; (skin); A3; (ACGIH 2004).
MAK: H;
Carcinogen category: 2;
(DFG 2004).
OSHA PEL†: none
NIOSH REL: Ca TWA 10 ppm (60 mg/m3) skin See Appendix A
NIOSH IDLH: Ca N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . Inhalation of the substance may cause lung oedema (see Notes). Exposure at high level may result in death. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the kidneys, ovary, testis , resulting in tissue lesions. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

ENVIRONMENTAL
DATA


N O T E S

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. EP-206, ERLA-2270, ERLA-2271, UNOX Epoxide 206, NCI-C60135, and Chissonox-206 are trade names. Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
