1 <br /> • The drill rig shall be driven or moved only after the mast has been lowered; and <br /> • The levelling jacks shall not be raised until the derrick is lowered. <br /> When drilling is to be conducted in contaminated soil, appropriate monitoring shall be <br /> conducted to assess worker exposure as well as effectiveness of control measures. Monitoring <br /> to be conducted will be specified in the Project HASP. Additional PPE may be required <br /> during these conditions. <br /> Hoisting Operations <br /> The following procedures shall be followed during hoisting operations: <br /> • Drillers should never engage the rotary clutch without watching the rotary table, <br /> and ensuring it is clear of personnel and equipment; <br /> • Unless the drawworks is equipped with an automatic feed control, the brake <br /> should not be left unattended, without first being tied down; <br /> • Drill pipe or casing should not be picked up suddenly; <br /> • Drill pipe should not be hoisted until the driller is sure that the pipe is latched in <br /> the elevator, or the derrickman has signalled that he may safely hoist the pipe; <br /> • During instances of unusual loading of the derrick or mast, such as when making <br /> an unusually hard pull, only the driller should be on the rig floor, and no one <br /> should be on the rig or derrick; <br /> The brakes on the drawworks of every drilling rig should be tested by each <br /> driller, when he comes on shift to determine whether they are in good order. <br /> The brakes should be thoroughly inspected by a competent individual each week; <br /> • A hoisting lure with a load unposed should not be permitted to be in direct <br /> contact with any derrick member or stationary equipment, unless it has been <br /> specifically designed for line contact; <br /> • Workers should never stand near the boring whenever any wire line device is <br /> being run; and <br /> • Hoisting control stations should be kept clean and controls labelled as to their <br /> functions. <br /> • Under no circumstances will personnel be permitted to ride the travelling block <br /> or elevators, nor will the catline be used as a personnel carrier. <br /> Catiine Operations <br /> The following procedures shall be followed during catline operations: <br /> • Only experienced workers will be allowed to operate the cathead controls. The <br /> kill switch must be clearly labelled and operational prior to operation of the <br />' catline; <br /> • The cathead area must be kept free of obstructions and entanglements; <br /> Mzros-09-94/vsT/94-0064 4-5 <br />
