Safety Precaution
- Make sure everyone working with DEMOSOL understands the possibility of blowouts, and has read the technical instructions thoroughly.
- DEMOSOL is a highly alkaline product; pH reaches 13 after contact with water and can cause severe irritation, especially eyes. Skin and eye contacts with DEMOSOL must be rinsed off with large amounts of cold water immediately without rubbing. Consult a doctor quickly.
- Wear safety goggles and rubber gloves at all times when handling, mixing and filling DEMOSOL. Dust-proof mask is recommended in poorly ventilated areas such as tunnels or mines.
- Cover the holes with a waterproof tarpaulin when rain occurs for the first 30 minutes after filling. Keep your face away from the holes filled by mortar. Stay away from filled holes at least 3 hours after filling to avoid blow-out shot. Keep people away from job site after filling.
- Do not fill holes with warm or bubbling mortar. Once filled holes start to smoke or steam, it is a sign that a blow out is about to occur. Clear the area of people immediately.
- Keep the jobsite clear of people immediately after filling the holes. In case people have to remain in the jobsite, cover filled holes with a tarpaulin.
- Beware of falling debris when expansion occurs.
