when operating on highways; and

(h) make certain everyone is clear of the machine before starting

the engine or the operation.

Noise

10.0.1.

(1) All practicable steps should be taken to reduce

the noise associated with the running of the tractor to a level not

exceeding the level established by the competent authority. When

levels have not been established, the level of

90

dbA at the driver's

ear is suggested. In all cases the exhaust system should include a

silencer.

(2) The noise level indicated in subparagraph (1) should not

be exceeded regardless of the mode of operation, the implements

used or the presence of a safety cab or frame.

(3) Where it is not feasible to reduce the noise level to 90 dbA

operators should use ear defenders to reduce sound levels to within

the limits of the table.

(4) The level of the noise generated by the tractor should be

determined by using approved national or international testing

methods.
