The information that is outlined within this section will be applicable if the site area of spillage of chemical / hazardous compounds more than 100m2:
The location of the spill relative to the sensitive water receivers will be determined;
Layer of physical absorbent will be deployed and contained the sensitive water receivers for the protection;
The Contractor will inform the relevant parties as listed on Table 2.2 immediately;
The on shift senior foreman or Emergency Team Leader’s delegates will in-charge all the mitigate measures implement on site in order to minimize the adverse effect;
