Grout Pumping and Injection Operations TR 003 All drilling and grouting records are to be handed into the shift supervisor at the end of shift. All care should be taken to complete these documents as precisely as possible, as this data greatly affects future development and engineering requirements of the mine. 5.3. Spill Treatment All care should be taken to conserve products and spills should be minimised. There is no environmental risks as both chemicals used in the grouting process are organic in nature and pose no risk. However the plant and surrounding area should be washed down at regular intervals during the grouting process to prevent slip/trip hazards. A point to remember is the Grout-Aid is liquified Silica, so when it dries, it poses an exposure risk if spilt in a non ventilated area. Therefore the product should be used in well ventilated areas, otherwise operators should use respiratory equipment and/or at minimum, dust masks. Spillage should be contained, then covered/absorbed with non-combustable absorbent material (vermiculite, sand or similar), then collected and placed in a suitable container for disposal. This is according to the information on ChemAlert.
