| 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.
|
AFFF, carbon
dioxide, dry sand, special powder. NO hydrous agents. NO water.
|
| 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: cool drums, etc., by spraying with water but avoid contact of the
substance with water. |
| EXPOSURE | STRICT
HYGIENE! |
IN ALL
CASES CONSULT A DOCTOR! | |
| Inhalation | Burning
sensation. Cough. Sore throat. Laboured breathing. Shortness of breath.
Symptoms may be delayed (see Notes). |
Ventilation,
local exhaust, or breathing protection. |
Fresh air,
rest. Half-upright position. Artificial respiration may be needed. Refer
for medical attention. See Notes. |
| Skin | Redness.
Pain. Blisters. Skin burns. |
Protective
gloves. |
Remove
contaminated clothes. Rinse skin with plenty of water or shower. Refer for
medical attention. |
| Eyes | Redness.
Pain. Severe deep burns. |
Safety
spectacles. Face shield. |
First rinse
with plenty of water for several minutes (remove contact lenses if easily
possible), then take to a doctor. |
| Ingestion | Burning
sensation. Abdominal pain. Shock or collapse. |
Do not eat,
drink, or smoke during work. |
Rinse mouth.
Do NOT induce vomiting. Give nothing to drink. Refer for medical
attention. |
| SPILLAGE DISPOSAL | PACKAGING & LABELLING | |||||||
| Evacuate
danger area! Consult an expert! Collect leaking liquid in sealable
containers. Do not use plastic containers. Absorb remaining liquid in sand
or inert absorbent and remove to safe place. Do NOT wash away into sewer.

self-contained breathing apparatus.) |

| IMPORTANT DATA | |||
| PHYSICAL
STATE; APPEARANCE: COLOURLESS FUMING LIQUID, WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride, phosgene. Reacts violently with water to produce hydrogen chloride (see ICSC0163). Reacts violently with alcohols, amines causing fire and explosion hazard. Attacks many metals in presence of water. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
ROUTES OF
EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance and the vapour are corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of may cause lung oedema (see Notes). Exposure may result in death. Medical observation is indicated. See Notes. | ||

| ENVIRONMENTAL DATA | |||
| NOTES | |||
| Reacts violently with fire extinguishing agents such as water. 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. Toxicological properties are inferred from
Methyldichlorosilane (ICSC 0297). | |||
