TYPES OF HAZARD
|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE-FIGHTING|
|FIRE||Extremely flammable.||NO open flames, NO sparks and NO smoking.||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.|
|EXPLOSION||Gas/air mixtures are explosive. Risk of explosion on contact with strong oxidants, strong acids or strong bases.||Closed system, ventilation, explosion-proof electrical equipment and lighting. NO contact with incompatible materials: See Chemical Dangers||In case of fire: keep drums, etc., cool by spraying with water.|
|EXPOSURE||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.|
|PACKAGING & 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.||

Relative density (water = 1): 0.8
Solubility in water: very good
Relative vapour density (air = 1): 1.08

Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
EU SCOEL recommendation: 0.2 ppm (8h); 0.4 ppm STEL; Skin sensitation, 2008. (Genotoxic carcinogen for which a practical threshold is supported.)
No UN number is presented because formaldehyde is not transported as a gas. It is usually transported as a solution.
See ICSC 0695 (Formaldehyde (37% solution, methanol free).
