OTHER PROPERTIES  
Description: Vermiculite is the mineralogical name given to hydrated laminar magnesium-aluminum-iron silicates which resemble mica in appearance. When subjected to heat, crude vermiculite has the unusual property of exfoliating or expanded into worm-like particles (the name vermiculite is derived from the Latin ‘vermiculare’, meaning to breed worms.)

.
Acute – Skin:
Acute – Inhalation:
No adverse effects expected.
Exposure to the dust may cause discomfort due to the particulate nature.
Not expected to be a skin irritant.
Inhalation of dust may result in respiratory irritation.
   
FIRST AID  
Ingestion: Rinse mouth with water – give plenty of water to drink. If vomiting occurs give further water. Seek medical advice.
Eye: Irrigate with copious quantities of water for 15 minutes. In all cases of eye contamination it is a sensible precaution to seek medical advice.
Skin: Wash contaminated skin with plenty of soap and water. If irritation occurs seek medical advice. Remove victim from exposure – avoid becoming a casualty.
Inhalation: Remove contaminated clothing and loosen remaining clothing. Patient to assume most comfortable position and keep at rest until fully recovered.
Advice to Doctor: Treat symptomatically.

May contain Crystalline silica: 0.1
Other Exposure Info: No value assigned for this specific material by the Occupational Health & Safety
Engineering Controls: Ensure ventilation is adequate to maintain air concentrations below exposure Standard. Avoid generating and inhaling dust. Keep containers closed when not in use.
Protective Equipment: No specific safety equipment required. Preferable to avoid skin and eye contact and inhalation of dust. Wear overalls, safety glasses and impervious gloves. Avoid generating and inhaling dust. If dust exists, wear dust mask/respirator meeting the requirements of AS1715 and AS1716. Always wash hands before eating, drinking or using the toilet.
Fire Hazards: Vermiculite is a fully oxidized non-flammable mineral. It is non-combustible

SAFE HANDLING INFORMATION  
Storage Precautions: Not defined as a Dangerous Good. Store in a dry place.
Spills and Leaks: Spills: Use respirators suitable for nuisance dust & eye protection. Sweep up, but avoid generating dust.
Disposal: Dispose in bulk or containerised according to local regulations. Normally approved for disposal at approved land waste sites.
   
OTHER INFORMATION Toxicology: Inhaling crystalline silica-containing dust can aggravate upper respiratory conditions such as asthma or emphysema. Long term exposure to mineral dust which contains crystalline silica can cause the lung disease silicosis. A recent review by the International Agency for Research into Cancer of public literature on the carcinogenic risk of silica and silicates has concluded that there is limited evidence for the carcinogenicity of crystalline silica to humans’.
