6.0 Safety & Health Plan
In order to minimize the occurrence of site accident, the provision of a safe working environment for workers to work is essential. Our company endeavors to make a zero accident record in each site. In addition to the above, the following safety and health precaution must also be implemented in achieving the minimization of site accidents.
All reasonable precautions would be taken to prevent danger of the workers and the public from accidents such as explosions, blasts, falling rock, unsafe power supply lines, falling to excavated pits etc. Further all necessary safety appliances such as safety goggles, safety helmets, masks, safety boots etc would be provided to all the workers including working staff.
