Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 65°C explosive vapour/air mixtures may be formed. Above 65°C use a closed system, ventilation. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE AVOID ALL CONTACT!  •INHALATION Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Refer for medical attention.  •SKIN MAY BE ABSORBED! Redness. Skin burns. Pain. Blisters. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Severe deep burns. Face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal cramps. Abdominal pain. Burning sensation. Shock or collapse. Weakness. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention. See Notes. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable metal containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: complete protective clothing including self-contained breathing apparatus). Separated from food and feedstuffs. Cool. Store only if stabilized. (See notes). Do not transport with food and feedstuffs.

International Chemical Safety Cards 2-HYDROXYPROPYL ACRYLATE ICSC: 0899 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance can polymerize due to heating, initiators, UV light. The substance decomposes on heating producing acrid fumes (acrylic acid, acroleine). OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.5 ppm; 2.8 mg/m3 (skin) (ACGIH 1997). OSHA PEL: none NIOSH REL: TWA 0.5 ppm (3 mg/m3) skin NIOSH IDLH: No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air will be reached rather slowly 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. Inhalation of vapour may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Boiling point: 225°C Relative density (water = 1): 1.06 Solubility in water: miscible Vapour pressure, Pa at 20°C: 5 Relative vapour density (air = 1): 4.5 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0 Flash point: 65°C Explosive limits, vol% in air: 1.8-? ENVIRONMENTAL DATA N O T E S Depending on the degree of exposure, periodic medical examination is indicated. 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. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. The effectiveness of phenolic inhibitors is dependent on the presence of oxygen. Store under air rather than inert atmosphere. Do NOT take working clothes home. The recommendations on this Card also apply to 2-hydroxyethyl acrylate.
