10-          Electrical Safety

10-1.       General

?       Only qualified electricians shall do electrical works.

?       To perform electrical works above 600V, safe work permit is required,

?       Consult with your supervisor.

?       Never use & metal ladder close to live wires.

?       Writing and live wires shall be run correctly so as not to get damaged or interfere with movements.

?       Avoid storage of materials/equipment and power lines. Otherwise erect warning flags so workers will not age lift for their transportation.

?       For power shovels, hoists and similar equipment close to power lines, use warning sign for the operator so the minimum distance of load to equipment will be preserved.

10-2.       Lock-Out

Whenever  hazardous condition or other possible hazards due to repair, maintenance or testing, are posed to personnel and equipment following procedure shall be used for assurance and safety.

This procedure shall also be applies for any work carried cut at or around operating equipment of possible hazards to worker.

1.               No one without providing verification of following shall work with electric equipment:

-      Equipment is electrically open and the power supply disconnect or control is locked out and tagged.

-      This work shall be carried out by one of the construction by one of the construction coordinators. This person shall ensure that the power supply is physically located and as per following is disconnected.

2.               Prior to power supply switch, a nominated and qualified worker shall ensure that the equipment load is reduced by stopping the motor or the operating equipment.

2.               Once the equipment has been stopped, the qualified worker shall open the power switch and makes sure that this switch is the right one.

3.               After equipment lock-out and prior to work start, the qualified worker shall attempt to start the equipment provided that the equipment is equipped with coal and control.

4.               Prior to work on a certain part of equipment, the coordinator shall issue a numbered lock plus the tag. Every worker shall fill in and sign the lock record form.

5.               Upon shutdown of power supply lock-out coordinator shall verify that the worker operating  on that particular part, has placed his lock in the lock-out box plus a tag indicating his name.

6.               When the worker finishes work on a locked-out equipment, the worker shall pick up his personal lock and tag from the disconnect or switch personal lock shall only be lifted by the relevant worker.

7.               Under no conditions, push button shall be locked or tagged instead of main disconnect or switch.

8.               When the main disconnect or switch is to be locked by more than one worker, it shall be performed by permission of worker's supervisor. Each worker shall sign the lock-tag.

For each trade, lock and tag shall be installed only once. When lock is being lifted, all group workers shall countersign the lock-tag, to verify the lock removal.

9.               If a worker leaves the property and has placed his lock on the lock-box, only Site Superintendent shall be authorized to remove the lock. He will first attempt to contact the worker Removal of looks by Site Superintendent shall be reported to Site Manager in writing.

10.            If a work is left incomplete and it will impact on the safe operation of equipment, workers supervisor possessing the lock on main disconnect or switch shall ensure that the tag no that switch absent workers shall remain.

11.            Prior to removal of the qualified workers lock, he will ensure that all personnel are informed and are at a safe location if the Employer or his subcontractors request that on the star: of work, commissioning or maintenance, the Employer's lock-out procedure to be applied, Construction Manager shall ensure that the applied procedure will not compromise the workers safety.

11-          Confined Spaces

Definition-Confined space is a work area that exit I entrance is limited due to design or construction, or where equipment, operations or spaces can be hazardous for safety and health.

?       Safe work permit in confined space shall be filled out be each employee prior to entry.

?       Confined space shall be ventilated and purged for securing the health and safety of workers.

?       Measures shall be taken to evacuate the workers from confined spaces during emergence.

?       Another worker trained in artificial respiration shall be stationed outside the confined space.

?       Air monitoring using gas monitors shall be carried out before workers are admitted into the confined spaces.

?       For any controlled product required for work, follow manufacturer's instructions for safe transportation especially with regards to ventilation and protection.

?       When using inflammable materials in confined spaces, consider the following precautionary measures:

-      Provide enough ventilation.

-      Control sparks and ignition sources.

-      Put off all pilot lights.

-      Place the fire extinguishers within reach.

12-          Heating

Propane is heavier that air, therefore it can collect in low areas and absorbed into clothing.

?       Only workers with training certificate shall be authorized to operate burners, heaters up to 400,000 BTU and propane burning vehicles.

13-          Diggings/Trenches

?       It required prior to work start, safe work permit for trenching shall be completed by qualified structural engineer.

?       Prior to work start for underground piping and power lines in the area, consult with related authorities. In some cases digging by hand may be required.

?       Make sure that prior to trenching the soil type has been identified since soil type will determine the stability of trench walls.

?       During trenching factors such as soil moisture overload , previous excavations, existing foundation and air shall be considered.

?       Prior to entry of workers into the trench, protection measures against bulging such as sloping, stabilizing the trench from work and buttressing to be performed.

?       Never enter a trench with more than 1.2m depth, unless it is slopped, buttressed and frame protected.

?       Consider the following during the diggings

-      Before starting the work, hedge around the trenching work area.

-      When trenching is deeper than 1.2m, provide buttress to stabilize the walls.

-      After heavy rain and snow melt-down, inspect trench walls before entrance.

-      Keep available first-aid in trenches and shafts.

-      Trench hedging shall be used to warn vehicles, pedestrians and workers.

?       Dug-out dirt could be used for hedging of one side of trench or similar digging. It shall be built-up at least half a meter above the trench ledge and one meter when use for hedging.
