|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Extremely flammable. Gas/air mixtures are explosive. Risk of explosion on contact with strong oxidants, strong acids or strong bases.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. NO contact with incompatible materials: See Chemical Dangers||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.|
|AVOID ALL CONTACT!|
|Inhalation||Cough. Sore throat. Burning sensation behind the breastbone. Headache. Shortness of breath.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.|
|Skin||Redness.||Protective gloves.||Remove contaminated clothes. Rinse skin with plenty of water or shower. Seek medical attention if you feel unwell.|
|Eyes||Watering of the eyes. Redness. Pain. Blurred vision.||Wear safety goggles or eye protection in combination with breathing protection.||Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Remove all ignition sources. Turn off gas at source if possible. Remove gas with fine water spray.||

|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.1 ppm as TWA; 0.3 ppm as STEL; (SEN); A1 (confirmed human carcinogen).
MAK: 0.37 mg/m3, 0.3 ppm; peak limitation category: I(2); carcinogen category: 4; pregnancy risk group: C; germ cell mutagen group: 5; sensitization of skin (SH).
EU-OEL: 0.37 mg/m3, 0.3 ppm as TWA; 0.74 mg/m3, 0.6 ppm as STEL; (skin sensitizer); (see Notes)
|Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
No UN number is presented because formaldehyde is not transported as a gas. It is usually transported as a solution.
See ICSC 0695.
Limit value for EU-OEL of 0.62 mg/m3 or 0.5 ppm for the health care, funeral and embalming sectors until 11 July 2024.
