First Aid: Take a copy of this MSDS to medical advisers if signs or symptoms of overexposure
occur and medical attention is required.
Swallowed: DO NOT induce vomiting. Wash out mouth with water and give plenty of water to
drink. If symptoms develop seek medical attention.
Skin: Remove all contaminated clothing. Wash gently and thoroughly with water and non-
abrasive soap for 15 minutes. Ensure contaminated clothing is washed before re-use or discard.
If contact is more than of minor nature, seek medical attention.
Eye: If contact with the eye(s) occurs, wash with copious amounts of water for approximately
15 minutes holding eyelid(s) open. Take care not to rinse contaminated water into the not-
affected eye. If symptoms persist seek medical attention.

vapour tight labelled plastic containers for eventual disposal. If large quantities of this material
enter the waterways contact the Environmental Protection Authority, or your local Waste
Management Authority.

                              7. HANDLING AND STORAGE
Storage: Store in a cool, dry, well-ventilated area, out of direct sunlight. Store away from heat
and ignition sources. Store in suitable, labelled containers. Protect from damage. Use suitable,
approved storage cabinets, tanks, rooms and buildings. Avoid any dust build-up by frequent
cleaning and suitable construction of storage area. Keep storage separate from populated work
areas. Inspect periodically for deficiencies such as damage or leaks. Have appropriate fire
extinguishers available in and near the storage area.
Incompatibilities: Store away from incompatible materials such as materials that support
combustion (oxidising materials).

Exposure Standards: No ingredients in this product have exposure standards, as outlined in the
standard Exposure Standards for Atmospheric Contaminants in the Occupational Environment
third edition, published by the National Occupational Health and Safety Commission/AGPS,
Engineering Controls: Use with good general ventilation. If dusts are produced local exhaust
ventilation should be used.
Personal Protective Equipment: All personal protective equipment should be selected, used,
maintained and decontaminated in accordance with manufacturers’ instructions and applicable
Clothing: Suitable work-wear should be worn to protect personal clothing, eg cotton overalls
buttoned at neck and wrist.

                           12. ECOLOGICAL INFORMATION
Biological Properties: This chemical forms a moderately acidic aqueous solution, and this
property may cause adverse environmental effects. It has a high biological oxygen demand, and
Waterco Limited               Aquachlor Metal Stain Remover                            Page 4 of 4

it may cause significant oxygen depletion in aquatic systems. If neutralized, it has low potential
to affect aquatic organisms, secondary waste treatment microorganisms and the germination and
growth of some plants. This product is expected to be readily biodegradable and is not likely to
bioconcentrate. When diluted with a large amount of water, this chemical released directly or
indirectly into the environment is not expected to have a significant impact.
Environment Protection: Prevent this material from entering waterways, drains and sewers.
