Physical dangers

Chemical dangers

Formula: Mg₃Si₂H₄O₉ / Mg₃(Si₂O₅)(OH)₄
Molecular mass: 554
Melting point: No melting point; decomposes (see Notes)
Density: 2.2-2.6 g/cm³
Solubility in water: none

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged inhalation may cause asbestosis (fibrosis of the lungs), pleural plaques, thickening and effusions. This substance is carcinogenic to humans. This substance causes cancer of the lung, mesothelioma, cancer of the larynx, and cancer of the ovary in humans. There is limited evidence that this substance causes colorectal cancer or cancer of the pharynx or stomach.

This substance causes cancer of the lung, mesothelioma, cancer of the larynx, and cancer of the ovary in humans. There is limited evidence that this substance causes colorectal cancer or cancer of the pharynx or stomach.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.1 f/cc as TWA; A1 (confirmed human carcinogen). MAK: carcinogen category: 1. EU-OEL: 0.1 fibres/ml as TWA

ENVIRONMENT

NOTES
The substance is heat resistant up to 500°C and completely decomposed at temperatures of 1000°C. NEVER use a domestic-type vacuum cleaner to vacuum the substance, only use specialist equipment. Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. The recommendations on this Card also apply to other forms of asbestos. Other CAS number: 132207-32-0 . The TLV value applies to fibres longer than 5µm with an aspect ratio equal to or greater than 3:1 as determined by the membrane filter method at 400-450X magnification (4-mm objective) using phase-contrast illumination.
