TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible but forms flammable gas on contact with water or damp air.
NO open flames, NO sparks, and NO smoking. NO contact with water or humidity.
Powder, carbon dioxide, NO water.
EXPLOSION Risk of fire and explosion on contact with water or humidity.

In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water. Combat fire from a sheltered position.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Burning sensation. Cough. Headache. Laboured breathing. Shortness of breath. Sore throat. Unconsciousness. Vomiting. Wheezing. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
•SKIN Redness. Skin burns. Pain. Blisters.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Pain. Loss of vision. Severe deep burns.
Safety goggles, 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 Abdominal pain. Burning sensation. Nausea. Shock or collapse. (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention. See Notes.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Evacuate danger area! Consult an expert! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. NEVER direct water jet on liquid. Do NOT let this chemical enter the environment. (Extra personal protection: chemical protection suit including self-contained breathing apparatus).
Fireproof. Provision to contain effluent from fire extinguishing. Cool. Dry.
Airtight.
UN Hazard Class: 8
UN Packing Group: II
ICSC: 0581 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:
FUMING COLOURLESS LIQUID , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on heating or on contact with water or humidity producing toxic and corrosive fumes including phosphoric acid, hydrogen chloride, hydrogen sulfide , causing fire and explosion hazard. Attacks many metals in presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

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 corrosive to the eyes, the skin and the respiratory tract. The vapour is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema (see Notes). Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. Exposure may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 125°C
Melting point: -35°C
Relative density (water = 1): 1.6
Solubility in water: reaction
Vapour pressure, kPa at 25°C: 2.9
Relative vapour density (air = 1): 5.8
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.1

ENVIRONMENTAL
DATA

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

N O T E S

Reacts violently with fire extinguishing agents such as water, foam. 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 spray, by a doctor or a person authorized by him/her, should be considered.
Transport Emergency Card: TEC (R)-80G10.
