Section 4: First Aid Measure

If poisoning occurs, immediately contact a doctor or Poisons

Information Centre, and follow the advice given. Show this Material Safety Data Sheet to a doctor.

Swallowed     If swallowed, DO NOT induce vomiting. Give a glass of water. Give one atropine tablet every 5 minutes until                            dryness of the mouth occurs. Get to a doctor or hospital quickly.

Eye contact     If in eyes, hold eyes open and flood with water for at least 15 minutes, and obtain immediate medical assistance.

Skin contact    Remove contaminated clothing. Wash affected areas with plenty of soap and water. Give one atropine tablet                             every 5 minutes until dryness of the mouth occurs. Get to a doctor or hospital quickly.

Inhalation      Remove victim to fresh air. Give one atropine tablet every 5 minutes until dryness of the mouth occurs. Get to a                         doctor or hospital quickly.

                           First Aid       Ensure washing facilities are available, including eyewash facilities. Maintain a Facilities       supply of atropine                                                      tablets 0.6 mg.

Special Fire Fighting Procedures: Firefighters should wear full protective gear, including self-contained breathing apparatus (AS/NZS 1715, 1716). If possible and without risk, remove intact containers from exposure to fire. Otherwise, spray unopened containers with water to keep cool. Contain fire-fighting water by bunding area with sand or earth to prevent it entering any bodies of water.


Section 6: Accidental Release Measures

Land spill    dike large spills using absorbent materials such as sand or clay. Recover and

or leak        contain as much free liquid as possible. Collect and contain contaminated absorbent and dike material for disposal. Absorb small spills                     with vermiculite. Place contaminated material in appropriate container for disposal.

If spilled on the ground, the affected area should be removed to a depth of 1 or 2 inches and placed in a appropriate container for disposal.

Do not flush material to public sewer systems or any waterways.

Wear appropriate protective clothing and equipment during cleanup activities. Ensure adequate decontamination of tools and equipment following cleanup.
