PRECAUTIONS FOR FIRE FIGHTERS

Not applicable. This product will not burn

Contact with hot or molten aluminium, lead, tin, zinc and their alloys may liberate highly flammable hydrogen gas.

In a general fire keep containers cool with water spray to prevent rupture of container. In a general fire wear full protective equipment and breathing apparatus. Move containers from fire area if it can be done without risk.

6. ACCIDENTAL RELEASE MEASURES

EMERGENCY PROCEDURES

This product is an alkaline liquid. Isolate hazard area and deny entry. Stop leak if it can be done without personal risk. CLEAN UP PROCEDURES

Small spills:                             Wear chemical goggle of face shield and rubber or                                                        PVC gloves and wipe up spill with mop or rags.

Place contaminated medium under water.

Large spills:                             Wearing full personal protective equipment, contain spill with sand, earth, sawdust or Vermiculite. Prevent run-off into drains or waterways. Neutralise with a weak acid such as vinegar or citric acid. Bail or pump any free liquidinto sealable plastic containers. Seal containers and label them in accordance with the Hazardous Substances Labelling Code. Hose down residue with plenty of water.

7. HANDLING AND STORAGE

PRECAUTION FOR SAFE HANDLING

STORAGE

Practice sound industrial hygiene. Wear rubber gloves, chemical goggles and clothing that will minimise skin contact. Wash hands before work breaks. Remove contaminated clothing and protective equipment before entering eating areas. Keep away from foodstuffs.

Store in a cool dry place and out of direct sunlight. Store away from strong acids, aluminium, lead, tin, zinc and their alloys as well as foodstuffs.

11. TOXICOLOGICAL INFORMATION

This mixture has not been tested for its health effects as a whole. The mixture has been classified as hazardous solely on the basis of the presence of sodium silicate. The toxicology data and health effects given below are those of a sodium silicate solution.

ACUTE HEALTH               Swallowed: This product is harmful by ingestion. The high pH is also                                           likely to cause chemical burns to EFFECTS           the gastrointestinal                                           tract. May cause vomiting and diarrhoea.LD50 (rat) 1100 – 1960 mg/kg.

Eyes: Highly irritant to eyes. May cause reddening of the eyes and lachrymation. Corneal damage may occur. Draize test: Severe (10 – 50 mg/24 hrs)

Skin: Irritant. Is absorbed through the skin. LD50 (rabbit) > 4640 mg/kg. Large or extended exposure may lead to a general depression of activity of the thorax and lungs, somnolence and dyspnea.

Inhaled: An unlikely route of entry if used as directed. Mists are irritating to mucous Membranes and may cause upper airways irritation. Inhalation of high concentrations may lead to chemical pneumonia.

CHRONIC HEALTH                         No data available. EFFECTS

12. ECOLOGICAL INFORMATION

ECOTOXICITY               Sodium silicate has not been classified as ecotoxic according to the criteria of the EEC Council Directive 67/548/CEE. However if the pH of the discharge into the environment is above acceptable limits

aquatic toxicity may result. An LD50 for fish exposed to concentrations of 300 – 500 mg/L for > 96 hrs and an EC50 for crustaceans exposed to 247 mg/L for 100 hrs has been reported.

PERSISTENCE AND          Being an inorganic, substance biodegradability tests are not applicable.                                           However, sodium silicate rapidly DEGRADABILITY      depolymerises into                                           silica compounds found naturally in the environment.

MOBILITY                       No data available

13. DISPOSAL CONSIDERATIONS

This product is a hazardous waste and may only be disposed of in accordance with applicable State and local regulations. These regulations vary from jurisdiction to jurisdiction and hence the user is advised to seek advice from the local authority before considering disposal. The disposal information given below is a general guide and does not replace the requirement of the local regulations.

DISPOSAL                    Small quantities may be diluted with large amounts of water to reduce the pH and then disposed of as non-hazardous waste. Empty containers should be treated in a similar manner. Large amounts must be neutralised with dilute or weak acid and may then be considered for landfill.

SPECIAL                       Ensure that the waste material has been uniformly neutralised                                           before dumping into a landfill. PRECAUTIONS

When large amounts of this product need to be disposed of the services of a registered, professional waste disposal organisation is highly recommended.
