2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Harmful if swallowed. Eye
The liquid causes burns to eyes. The vapour causes transient eye irritation. Temporary foggy vision has also bee reported in some cases. Skin
The liquid causes burns to skin. There is danger of skin absorption. Harmful by skin contact. Inhaled
The vapour is an irritant to the eyes, nose, throat, lungs and skin. Harmful by inhalation. 2.2 Health Effects - Chronic
Chronic exposure to this product caused skin, lung and kidney injury in animal studies. Chronic skin absorption may cause liver and kidney damage. Mutagenic and sensitising effects are not expected.
2.3 First Aid
Swallowed
If swallowed, rinse mouth out thoroughly and then drink 1 - 3 cups of water or milk. Seek medical attention immediately. DO NOT induce vomiting.
Eye
If eye contact occurs, immediately rinse under running water for at least 15 minutes with eyelids held open. Seek medical attention immediately.

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 LD50 = 1910 mg/kg (Rat) Dermal LD50 = 500 mg/kg (Rabbit) Inhalation LC50 = >260 mg/L/4h (Rat)
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
Worksafe recommends : TWA 20 ppm (71 mg/m3) STEL 30 ppm (107 mg/m3) Absorption through the skin may be a significant source of exposure.
3.2 Engineering Controls
Ensure workplace is well ventilated to maintain air concentrations below exposure standard, including the use of local exhaust ventilation.
3.3 Personal Protection
Avoid contact with skin and eyes. Avoid inhalation of vapour. The following personal protective equipment is recommended Protective goggles Protective gloves (Butyl rubber/Nitrile/PVC) Organic vapour respirator if vapour is likely or expected Protective clothing Protective equipment used should comply with relevant n Standards Limit exposure to product wherever possible. Wash hands and face thoroughly before work breaks and before going home.
3.4 Flammability
Flammable. Keep away from all sources of ignition and heat. Earth all containers to reduce the possibility of sparks from static electricity. A very dangerous fire hazard when exposed to heat, flame or oxidising substances. Vapours can form flammable mixtures with air. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Store in accordance with all Commonwealth, State or Territory regulations relevant to Class 3 liquids. Transport in accordance with the n Dangerous Goods Code. Ensure thorough ventilation in all storage areas and workplace. Store in a cool, dry area. Take precautions against static discharges. Sources of ignition should be kept well clear. The product has a minimum shelf-life of 2 years when stored correctly in sealed containers. Avoid storage or transport with oxidising substances, acids or acid forming substances.
4.2 Packaging / Labelling UN No. 2054 Class 3 Sun Risk None Allocated Hazchem Code 2P Pack Group III EPG No. 3A3 Shipping Name MORPHOLINE Hazard CORROSIVE鼿ARMFUL
Risk Phrases R10 Flammable. R34 Causes burns. R20/21/22 Harmful by inhalation, in contact with skin and if swallowed.
Safety Phrases S23:MORPHO Do not breathe fumes/vapour. S36 Wear suitable protective clothing. S45 In case of accident or if you feel unwell, contact a doctor or immediately (show the label where possible).
4.3 Spills and Disposal
Spills
Sources of ignition should be kept well clear. Clean up personnel should wear protective clothing with goggles, gloves and approved vapour respirator.
Disposal
Dispose of by incineration at an approved waste disposal facility in accordance with all Local, State and Federal regulations.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Flammable liquid. Vapours are heavier than air and may travel to a source of ignition and flash back. Combustion may produce irritants and toxic gases including ammonia and nitrogen oxides. Incompatible with oxidising substances or acids. Exothermic reaction with acids.
Extinguishing Media
In case of fire use water, foam, carbon dioxide or dry chemical. Fire fighters should wear full protective clothing including self-contained breathing apparatus. Water may be ineffective except to cool and dilute source. Contain and dispose of fire residues and contaminated extinguishants in accordance with local regulations. 5 OTHER INFORMATION
