IDENTIFICATION OF DANGERS
| Risk symbol | Principal risks for people and the environment |
|---|---|
|
Xi |
Hydraulic lime is irritant for eyes, respiratory track and mucous membranes
Risk of severe eye damage in cases of splashes of powder or wet mortar in the eyes
Once hydrated, the lime increases alkalinity and therefore can irritate or dry the skin
In cases of significant ingestion, the product is caustic for the digestive tract. It can cause burning of the mouth, oesophagus and stomach.
The product does not present particular risks for the environment subject to the Handling Precautions below and the respect of national or local disposal directives. |

Not listed |
ECOLOGICAL INFORMATION
|
Mobility |
None |
|
Potential Bio-accumulation |
None |
|
Ecotoxicity |
This product is an alkaline material so that any increase in the pH of water initiates the carbonation process. Over time, this re-constitutes Calcium Carbonate (CaCO3) which is a neutral material in ecological terms. |
DISPOSAL INFORMATION
The product in its hardened state can be disposed as normal construction debris.
Dispose of used bags in authorised refuse areas in accordance with local directives.
TRANSPORT INFORMATION
The product is not considered hazardous in accordance with ADR, RID, IMDG and IATA regulations.
