TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking. NO contact with hot surfaces.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Confusion. Dizziness. Dullness. Headache. Nausea. Vomiting.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention. See Notes.
 •SKIN MAY BE ABSORBED! Dry skin. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
 •EYES Severe deep burns.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Unconsciousness. (Further 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.

PACKAGING & LABELLING

Evacuate danger area! Consult an expert! Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Personal protection: self-contained breathing apparatus.
Fireproof. Separated from strong oxidants, acids, food and feedstuffs .
Do not transport with food and feedstuffs.
UN Hazard Class: 3
UN Subsidiary Risks: 6.1
UN Packing Group: II
ICSC: 0320 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are easily formed.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including nitrogen oxides and hydrogen cyanide . Reacts violently with strong oxidants causing fire and explosion hazard. Reacts with acids, steam, warm water giving off toxic and flammable hydrogen cyanide.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
OSHA PEL: none
NIOSH REL: TWA 6 ppm (14 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, 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 may cause effects on the iron metabolism , resulting in asphyxia. Exposure may result in unconsciousness, cardiac dysrhythmia and death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 97°C
Melting point: -92°C
Relative density (water = 1): 0.78
Solubility in water, g/100 ml at 20°C: 10
Vapour pressure, kPa at 20°C: 5.2
Relative vapour density (air = 1): 1.9
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.05
Flash point: 6°C c.c.
Explosive limits, vol% in air: 3.1-?
Octanol/water partition coefficient as log Pow: 0.16

ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to aquatic organisms.

N O T E S

Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home. Card has been partly updated in October 2005. See section Emergency Response.
Transport Emergency Card: TEC (R)-30GTF1-II
