4. FIRST AID MEASURES

 

Inhaled: Keep victim calm and remove to fresh air if safe to do so. Obtain medical treatment immediately.

Skin Contact: If skin contact occurs, remove contaminated clothing and wash skin thoroughly with water and follow by washing with soap if available. If redness, swelling, pain and/or blisters occur, transport to the nearest medical facility for treatment.

Eye Contact: Hold eyes open and wash thoroughly with flowing water for 15 minutes. Seek prompt medical attention by a doctor.

Swallowed: Do NOT induce vomiting. If vomiting occurs spontaneously, keep head below hips to prevent aspiration. Call doctor and/or transport to hospital promptly.

First Aid Facilities: Provide potable water to rinse eyes or skin, eye baths and safety showers.

 

5. FIRE FIGHTING MEASURES

 

Flammability: Flammable liquid. Vapour may form explosive mixtures with air. Avoid heat and all ignition sources.

Flash Point: 27C

Hazchem Code: 3[Y] E

Suitable Extinguishing Media: Extinguish with foam, water spray, fog, dry chemical or carbon dioxide. Do not use water in a jet.

Hazards from combustion products: Carbon monoxide may be evolved if incomplete combustion occurs. Will float and can be reignited on surface water. Vapour is heavier than air, can spread along ground and distant ignition is possible.

MSDS - Aquagard M Clear Primer 25/08/2010 Page 2 of 3

Precautions for Fire Fighters and Special Protective Equipment (PPE): Wear full protective clothing and self-contained breathing apparatus.

 

6. ACCIDENTAL RELEASE MEASURES

 

Spills & Disposal: Avoid contact with spilled or released material. Shut off leaks, if possible without personal risks. Remove all sources of ignition in the surrounding area. Use appropriate containment to avoid environmental contamination. Prevent from spreading and entering waterways using sand, earth or other appropriate barriers. Take precautionary measure against static discharge. Ensure electrical continuity by bonding and earthing all equipment.

Methods & Materials for Containment & Clean Up Procedures: For small spills (<1 drum), transfer by mechanical means to a labelled, sealable container for product recovery or safe disposal. Allow any residues to evaporate or use an appropriate absorbent material and dispose of safely.

For larger spills (>1 drum), transfer by means such as a vacuum truck to a salvage tank for recovery or disposal. Do not flush residues with water. Retain as contaminated waste. Allow any residues to evaporate or use an appropriate absorbent material and dispose of safely.

 

7. HANDLING & STORAGE

 

Handling: Avoid breathing of or contact with material. Use in well ventilated areas. Wash thoroughly after handling. Avoid contact with skin and eyes and clothing. Handle open containers in well ventilated area.

Storage: Store in a cool, well ventilated place away from heat and ignition sources. Keep partially used product containers closed. Store away from strong oxidants, foodstuffs, clothing and keep out of reach of children.

Dispensing: Electrostatic charges may be generated during transfer. Electrostatic discharge may cause fire. Ensure electrical continuity by earthing all equipment.

 

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

 

National Exposure Standards:

 

 

TWA

STEL

Isocyanate (as NCO)

0.02mg/m3 sensitiser

0.07mg/m3

Xylene, mixture of isomers

350 mg/m3

655 mg/m3

 

TWA - (Time Weighted Average) - Maximum average airborne concentration experienced over an eight hour working day, for a five day working week over an entire working life.

STEL - (Short Term Exposure Limit) - Average airborne concentration over a 15 minute period which should not be exceeded at any time during a normal eight hour working day.

Exposure Limits: Not established for product or individual components.

Ventilation: Provide general and/or local exhaust ventilation, depending on type of operations, to control airborne exposures.

Personal Protective Equipment (PPE):

Respiratory: If work practises do not maintain airborne level below the exposure standard, use appropriate respiratory protection equipment. When using respirators, select an appropriate combination of mask and filter and select a filter for organic gases and vapours (boiling point >65C). Respirators

should comply with AS1716 or an equivalent approved by a state/territory authority.

Hands: Use nitrile solvent resistant gloves or PVC and neoprene for incidental splashes.

Eyes: Wear chemical goggles. Eye wash facilities should be located in the immediate work area.

Protective Clothing: Use chemical resistant glove/gauntlets, boots and apron.

Engineering Controls: Ensure adequate ventilation is provided and air concentration below exposure standards. Avoid generating and inhaling mists. Keep containers closed when not in use.

 

9. PHYSICAL & CHEMICAL PROPERTIES

 

Appearance: Transparency liquid Solubility in water: Not soluble

Odour: Mild Aromatic Specific Gravity: 1.1 (@25C)

pH: N/A Flashpoint: 26C

MSDS - Aquagard M Clear Primer 25/08/2010 Page 3 of 3

Condition to Avoid: Avoid heat, sparks, open flames and other ignition sources.

Incompatible Materials: Strong oxidising agents.

Hazardous Decomposition Products: Thermal decomposition is highly dependant on conditions. S complex mixture of airborne solids, liquids, gases, including carbon monoxide, carbon dioxide and other organic compounds will be evolved when this material undergoes combustion or thermal or oxidative

degradation.

 

11. TOXICOLOGICAL INFORMATION

 

Inhaled: Low toxicity - LC50>20mg/14 hours, Rat. Inhalation of vapours or mists may cause irritation to the respiratory system. High concentrations may cause central nervous system depression resulting in headaches, dizziness and nausea; continued inhalation may result in unconsciousness and/or death.

Skin Contact: Irritating to skin.

Eye Contact: Irritating to eyes.

Swallowed: Expected to be of low toxicity: LD50>2000mg/kg, Rat. Aspiration into lungs when swallowed or vomited may cause chemical pneumonitis which can be fatal.

Chronic: Central nervous system: repeated exposure affects the nervous system.

Liver: can cause liver damage.

Kidney: can cause kidney damage.

 

12. ECOLOGICAL INFORMATION

 

Ecotoxicity:

Fish: Toxic 1

Aquatic Invertebrates : Toxic 1

Algae: Toxic 1

Mobility: Floats on water, highly mobile and may contaminate groundwater.

Persistence/ Degradability: Readily biodegradable. Oxidises by photo-chemical reactions in air.
