Suitable extinguishing media: Use carbon dioxide, foam, dry chemical or water spray to extinguish, as
required for fire in surrounding materials.
Hazards from combustion products: None
Special protective precautions and None
equipment for fire fighters:
HAZCHEM Code: None allocated
SECTION 6: ACCIDENTAL RELEASE MEASURES
Clean Up Procedure: Dust and waste should be cleaned up by bagging, wet sweeping and/or
vacuuming. Waste should be placed into containers and disposed of as trade
waste in accordance with local waste disposal authority guidelines.
SECTION 7: HANDLING AND STORAGE
Handling: Manual handling should be in accordance with Manual Handling Regulations
and Codes.
Storage: This product should be stored in its factory packaging in a dry area.
Incompatibilities: Do not store with strong acid, alkalis or oxidizing agents.
SECTION 8: EXPOSURE CONTROLS / PERSONAL PROTECTION
National Exposure Standards: National Occupational Health & Safety Commission (NOHSC)
Australia Occupational Exposure Standard:
Calcium sulphate: TWA 鈥? 10 mg/m3 as inspirable dust
Calcuim carbonate: TWA 鈥? 10 mg/m3 as inspirable dust
Notes on Exposure Standards: All occupational exposures to atmospheric contaminants should be kept to as
low a level as is workable (practicable) and in all cases to below the National
Standard.
TWA (Time Weighted Average): the time-weighted average airborne
concentration over an eight-hour working day, for a five-day working week over
an entire working life. According to current knowledge this concentration should
neither impair the health of, nor cause undue discomfort to, nearly all workers.

Biological Limit Values: No biological limit allocated
ENGINEERING CONTROLS
Ventilation: Work practices should minimize the release of and exposure to dust. General
room ventilation should be adequate, but local mechanical ventilation may be
required it dust is generated, particularly in confined spaces. If engineering
controls and work practices are not effective in controlling dust, then personal
protective equipment may be required.
Work areas should be cleaned regularly by damp sweeping or
Special Consideration for
vacuuming. Recommendations on Exposure Control and Personal Protection
Repair &/or Maintenance of
Contaminated Equipment: should be followed.
PERSONAL PROTECTION
Personal Hygiene Work clothes should be washed regularly. Wash hands before eating, drinking,
using the toilet, or smoking.
Skin Protection: Loose comfortable clothing should be worn. Direct skin contact should be
avoided by wearing long sleeved shirts and long trousers, a cap or hat, and
gloves (standard duty leather or equivalent AS 2161).
Eye Protection: Safety spectacles with side shields or coverall goggles with direct ventilation
(AS/NZS 1336) should be worn when working in a dusty environment.
Respiratory Protection: An approved particulate respirator conforming to Australian Standards AS/NZS
1715 and AS/NZS 1716 should be worn when working in a dusty environment.
Respirators should be correctly fitted, maintained in good condition, and kept in
clean storage when not in use.

SECTION 11: TOXICOLOGICAL INFORMATION
Toxicology data: Not available on this product, but anticipated to be very low with LD50 >5000 mg/kg.
Health Effects: Acute (short term)
Swallowed: Unlikely under normal conditions of use, but swallowing the powder and dust may result in
abdominal discomfort.
Eyes: The powder and dust can irritate the eyes causing watering and redness. Exposure to dust may
aggravate pre-existing eye conditions.
Skin: The powder and dust, particularly in association with heat and sweat, can cause irritation, but it
is not absorbed through the skin.
Inhaled: The powder and dust can cause irritation of the nose, throat and lungs resulting in excess
mucus and coughing.
Health Effects: Chronic (long term)
Eyes: Dust may cause irritation and inflammation of the eyes and aggravate pre-existing eye
conditions.
Skin: Repeated heavy contact with the dust may cause drying of the skin and can result in skin rash
(dermatitis) typically affecting the hands. Over time this may become chronic and can also
become infected.
Inhaled: Repeated exposure to the dust may result in increased nasal and respiratory secretions and
coughing. Inhaling dust may aggravate pre-existing respiratory conditions.
SECTION 12: ECOLOGICAL INFORMATION
Eco-toxicity: The physical and chemical nature of the product, and toxicological data on ingredients, indicate
that this product is a relatively low risk.
Persistence and Product is persistent and would have a low degradability.
Degradability:
