TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, 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.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


Inhalation Cough. Dizziness. Dullness. Headache. Laboured breathing. Shortness of breath. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Evacuate danger area! Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Personal protection: self-contained breathing apparatus.

METHYL FORMATE ICSC: 0664
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour mixes well with air, explosive mixtures are easily formed.

CHEMICAL DANGERS:
Reacts vigorously with oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 100 ppm as TWA, 150 ppm as STEL; (ACGIH 2004).
MAK: 50 ppm, 120 mg/m; Peak limitation category: II(4); skin absorption (H); Pregnancy risk group: C; (DFG 2004).
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 very quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin. The vapour is irritating to the eyes and the respiratory tract. The substance may cause effects on the central nervous system. Medical observation is indicated.

PHYSICAL PROPERTIES
Boiling point: 32C
Melting point: -100C
Relative density (water = 1): 0.98
Solubility in water, g/100 ml at 20C: 30
Vapour pressure, kPa at 20C: 64
Relative vapour density (air = 1): 2.07
Relative density of the vapour/air-mixture at 20C (air = 1): 1.7
Flash point: -19C
Auto-ignition temperature: 449C
Explosive limits, vol% in air: 5-23
Octanol/water partition coefficient as log Pow: -0.21

NOTES
The odour warning when the exposure limit value is exceeded is insufficient.
Card has been partly updated in October 2004 and 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
