2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Swallowing can result in severe irritation of the gatrointestinal tract. Eye
A severe eye irritant. Contamination of the eyes can result in permanent injury. Corrosive to eyes; contact can cause corneal burns. Skin
Contact with skin will result in severe irritation. Corrosive to skin - may cause skin burns. Can be absorbed through the skin. Inhaled
Inhalation of vapour, mists or aerosols can result in irritation of mucous membranes and respiratory tract. 2.2 Health Effects - Chronic
No information available.
2.3 First Aid
Swallowed
Immediately rinse cmouth with water. Give water to drink. DO NOT induce vomiting. Seek immediate medical attention.
Eye
Immediately irrigate with copious amounts of water for at least 15 minutes. Eyelids to be held open. Remove clothing contaminated and wahs skin. Urgently seek medical assistance. Transport to hospital or medical centre.
Skin
Immediately wash contaminated skin with plenty of water. If swelling, redness, blistering, or irritation occurs seek medical attention. For skin burns, immediately flood burnt area with plenty of water and cover with a clean, dry dressing. Seek immediate medical advice. Can be absorbed through the skin with resultant toxic effects. Seek medical advice.
Inhaled
Remove victim from exposure - avoid becoming a casualty. Remove contaminated clothing and loosen remaining clothing. Allow patient to assume most comfortable position and keep warm. Keep at rest until fully recovered. If breathing laboured and patient cyanotic (blue), ensure airways are clear and have qualified person give oxygen through a face mask. If breathing has stopped apply artificial respiration at once. In event of cardiac arrest, apply external cardiac massage. Seek medical advice.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Treat symptomatically based on judgement of doctor and individual reactions of patient.
2.6 Toxicity Data
Oral (rat) LD50: 193 - 3200 mg/kg. Dermal (rabbit) LD50: 295 - 750 mg/kg (corrosive). Inhalation (rat) LC50: 3.54 - 5.13 mg/m3/4hr. Eyes: 50 ul of undiluted acrylic acid into the conjunctiva sac of rabbit eye caused immediate spontaneous corrosion of the conjunctiva and of the cornea were observed; these lesions were irreversible. Skin: Moderate to severe necrosis was observed after application of undiluted acrylic acid to the unoccluded skin of rabbits for 24 hours. Neat acrylic acid or any technical acrylic acid by a process which includes distillation is not a skin sensitiser.
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
TWA: 2 ppm (5.9 mg/m3).
3.2 Engineering Controls
Ensure ventilation is adequate to maintain air concentrations below exposure standard. Use with local exhaust ventilation or while wearing acid mist repsirator/mask. Vapour heavier than air - prevent concentration in hollows or sumps. Do not enter confined spaces where vapour may have collected
3.3 Personal Protection
Wear overalls, face shield, elbow-length impervious gloves, splash apron and rubber boots. If inhalation hazard exists, wear organic acid mist respirator meeting requirements of AS/NZS 1715 and AS/NZS 1716. Always wash hands before smoking, eating, drinking or using the toilet. Wash contaminated clothing and other protective equipment before storing or reusing.
3.4 Flammability
Flammable liquid. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Store in well ventilated area. Store in a cool place and out of direct sunlight. Store away from sources of heat and ignition. Store away from peroxides, other polymerisation inhibitors, alkalis such as sodium hydroxide, oxidizing agents and amines. Proper grounding procedures should be followed when product is being transferred. ALways open containers slowly to allow any excess pressure to vent. Keep containers closed at all times - check regularly for leaks. Air should be used to blanket and sparge sotrage vessels in order for inhibitor to function. Oxygen-free atmospheres should never be used. TO PREVENT HAZARDOUS POLYMERISATION: Store in well ventilated area between 15-25 deg C. If product freezes, melt only in a temperature controlled environment. Only use temperatures up to 45 deg C to thaw bulk containers, and 20-33 deg C for drums. Stir product regularly while heating/melting to assure thorough mixing and distribution of the polymerisation inhibitor.
4.2 Packaging / Labelling UN No. 2218 Class 8 Sub Risk 3 Hazchem Code 2WE Pack Group II EPG No. 19P Shipping Name ACRYLIC ACID, INHIBITED Hazard CORROSIVE
Risk Phrases R10 Flammable. R34 Causes burns. R41 Risk of serious damage to eyes.
Safety Phrases S1/2 Keep locked up and out of the reach of children. S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S36 Wear suitable protective clothing. S45 In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible).
4.3 Spills and Disposal
Spills
Clean up personnel should wear full protective clothing including respiratory protection. Shut off all possible sources of ignition. Clear area of all unprotected personnel. Do not allow spill to enter drains or water courses.
Contain spill. Use absorbent (soil, sand. or other non-combustible). Neutralise with lime or soda ash. Collect spilled material into sealable and labelled containers and hold for later disposal.
Disposal
Dispose according to all local, state, and federal regulations.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Flammable liquid. Heating can cause expansion or decomposition leading to violent rupture of containers. On buring will emit toxic fumes including oxides of carbon. If safe to do so, remove containers from bath of fire. Keep containers cool with water spray.
Extinguishing Media
Firefighters should wear full protective clothing including self contained breathing apparatus. Use water fog/spray, foam, dry agent (carbon dioxide, dry chemical powder) as extinguishing media. Uncontrolled polymerisation can cause rapid evolution of heat and increased pressure which can result in violent rupture of storage vessels. 5 OTHER INFORMATION
