Activity ( Job Steps )

1.

Work permit from Client to be obtained.

Potential Hazard  Unauthorized commencement of works may result in exposing workers and or potential to harm or danger

Who/ What Might Be Harmed Injury to IMCO Personnel and or client property.

LD : Lost Workdays

Control/ Recovery Measures  Authorized PTW holder shall ensure obtaining and maintaining valid work permit.  The worksite supervisor responsible for this activity has to check the PPE of his staff to ensure that all required items are available and properly used.  Inform all workers regarding permit condition before work starts.  Worksite supervisor shall conduct toolbox talks about nature of works and associated potential hazards and their essential precautionary measure.

Control/ Recovery Measures replace PPE that has signs of defect.  PPE must include both hearing protection as well as dust inhalation protection.  Ensure that adequate shaded areas are provided.  Provide proper ventilation and drink plenty of water even if you are not thirst.  Wear loose fitting full length clothing that can breathe.  Ensure that all markers and signage are of a suitable height to be clearly seen and sufficient lighting is placed to identify the area at night.  Ensure that all equipment is having valid QP certificates to work in the vicinity.  Make sure all operators know the safe limitations of their equipment.  Assigned a competent banksman when equipment is moving at the working area.  Ensure strict control measure to separate mechanical plant and enforce swing radius area as no go area for any person or vehicle in order to avoid collisions.  Set control measure in place that all fuel transfers take place under strict guidelines. Fuel is only transferred by purpose built fuel delivery tanker.

Page 4 of 8

Control/ Recovery Measures  Ensure all machines and equipments are in good condition.  Regular preventive and corrective maintenance of equipment must be observed.  Drip trays are used to prevent any spillage. Make sure all vehicles are routinely inspected and maintained to reduce the risk of mechanical failure.  In the event that there is ground contamination ensure all contaminated ground is collected and placed into plastic bags, removed to a waste storage container until removed from site to a hazardous waste disposal site.  Deploy equipment delivering materials in such manner that no congestion inside shall happen and no parking anytime in the work area.  Use only designated roads for delivery of concrete.  Ensure to wear suitable respiratory protective equipment such as a P, N or R 95 respirator when fumes from dust can’t be avoided.  Remove person to fresh air. If discomfort persists seek medical advice.  Ensure to wear loose clothing in
