i <br /> Making and Breaking Joints <br /> The following procedures will be followed when making and breaking joints: <br /> • Tongs should be used for the initial making up and breaking of the joint. The <br /> rotary table should not be used for the initial breaking of a joint. <br /> • Employees making or breaking joints should not be permitted to stand within the <br /> arc of the tong handles when the tong pull line is in tension. Employees should <br /> handle the tongs only by the appropriate handles. <br /> • Employees should be trained in the safe use of spinning chains. Spinning chains <br /> should not be handled near the rotary table while it is in motion. <br /> 4.2 <br /> .5 Hearing Conservation Program <br /> All on-site IT and subcontractor personnel shall wear hearing protection, with a Noise <br /> Reduction Rating (NRR) of at least 25, when noise levels exceed 85 dBA (or wherever voices <br />' must be raised in order to be understood at arms length). All site personnel who may be <br /> exposed to noise shall also receive baseline and annual audiograms and training as to the <br /> causes and prevention of hearing loss, in accordance with rr Procedure HS402. <br /> Whenever possible, equipment that does not generate excessive noise levels will be selected <br /> for this project. If the use of noisy equipment is unavoidable, wherever possible, barriers or <br /> increased distance will be used to minimise worker exposure to noise. <br /> 4.2.6 Heat Stress/Cold Stress Prevention <br /> 4.2.6.1 Heat Stress <br /> It is not anticipated that heat stress will be a problem due to the moderate climate of the site <br /> during late fall. Should weather conditions change and become unseasonably warm, measures <br /> will be taken in preventing heat stress, including: <br /> • Site workers will be encouraged to drink plenty of water throughout the day. <br /> .y <br /> They will be advised to slightly increase their salt intake by lightly salting their <br /> food. <br /> • On-site drinking water will be kept cool to encourage personnel to drink <br /> frequently. <br /> • All personnel will be advised of the dangers and symptoms of heat stroke, heat <br /> exhaustion and heat cramps. <br /> • All employees shall be informed of the importance of adequate rest, acclimation <br /> and proper diet in the prevention of heat stress disorders. <br /> Mzf°5-09-94/U T/9a-oo6a 4-7 <br />
