2. Composition / Information on Ingredients
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 expanding.
3. Hazards Identification
|Routes of exposure
|Inhalation and Ingestion
|Vermiculite is of low acute toxicity, but prolonged exposure to any mineral dust could cause respiratory problems
|Symptoms of exposure (Acute effects)
|Symptoms of exposure (Chronic effects)
|Possible impairment of lung function after long-term exposure to dust levels in excess of OES- TWA
|Any conditions aggravated by dust (e.g. asthma or pneumoconiosis) may be aggravated by exposure
4. First Aid Measures
|First Aid Measures
|Wash thoroughly with soap and water after use
|Irrigate thoroughly with water. Obtain medical advice if any pain or redness persists
|There are no known adverse effects. If ingested in large quantities, wash mouth out with water and give water to drink. Do not induce vomiting
|If inhaled in large quantities and mechanical irritation or discomfort occurs, allow the patient to rest in a well-ventilated room
|Injection under pressure
|Advice to physicians
|No special requirements. In all cases should symptoms persist seek medical advise
5. Fire Fighting Measures
Non-flammable, no special precautions necessary.
Extinguishing media : Not applicable.
Special exposure hazard : Not applicable. Protective equipment : Not applicable.
6. Accidental Release Measures
Leaks and Spills : Vacuum spillages.
Personal precautions : No special requirements.
Environmental precautions : No special requirements.
7. Handling and Storage
Handling precaution: Avoid creating airborne dust wherever
possible. Where dust is generated then engineering dust control measures, e.g. LEV, should be considered.
Storage precautions: No special precautions. Shelf life: Indefinite. Specific uses: N/A
8. Exposure Controls/Personal Protection
|Exposure Controls/Personal Protection
|Exposure limit values
|As per HSE Guidance Notes EH40. See section 2.
|Use appropriate engineering controls to
maintain dust levels below OES-TWA limits.
|Dust masks conforming to EN149 FFP2S or FFP3S should be used if OES-TWA limits are exceeded.
|No special precautions
|Ensure compliance with statutory environmental legislation controls.

11. Toxicological Information
|Symptoms of overexposure for each potential route of exposure
|Acute Toxicity: –
Oral LD50 (rat) (mg/kg) Dermal LD50 (rat) (mg/kg) Inhalation LC50 4hr(rat) (mg/l)
|Not known but since vermiculite acts as an inert material in Acute Toxicity tests, LD50/LC50 values would be high.
|Irritation to skin
|Can cause mild irritation
|Irritation to eyes
|Can cause mild irritation
Repeated dose toxicity
|Not known but information available shows material to be non-toxic. Chronic long- term respirable problems are possible
The review of available experimental data suggests that over exposure to respirable crystalline silica (RCS) dust can cause silicosis, a form of progressive pulmonary fibrosis. Long-term exposure to high levels of RCS dust can also lead to an increased risk of developing lung cancer. However, the phase 2 review carried out by the HSE (EH75/5) concludes that although RCS is a cause of lung cancer in humans, it is not a potent carcinogen. As a result of these findings CHAN35 has been issued by the HSE suggesting that for RCS, employers should aim to control exposures to 0.1mg/m3 (8hr TWA) or below. The HSE is not proposing a formal change to the MEL because a new system of Occupational Exposure Limits (OELs) is planned to be in place by the end of 2004, which is likely to overtake any new MEL developments
12. Ecological Information
Persistence & degradability
Bio accumulative potential
Other adverse effects
|No information available, but since the material is naturally occurring, unreactive, insoluble and non-biodegradable, no
Ecological problem is known or expected.
13. Disposal Information
