Text from
the OSHA Logging Standard Amendment issued September 8, 1995 in the Federal RegisterParagraph
(f)(2)(iv) -- Machine Operation on Slopes
OSHA stayed the provision requiring that logging machines not be operated on any slope
greater than the maximum slope recommended by the manufacturer after learning that logging
machine manufacturers do not specify a maximum slope on which particular logging machines
can be safely operated. The intent of this requirement was to ensure that machines used on
sloping terrain are operated in a manner that will prevent the machine from tipping or
rolling over. As OSHA explained in the preamble to the final rule, injuries and fatalities
resulting from tipping and rollover accidents are prevalent in the logging industry
because of the rough terrain on which logging machines operate (Ex. 2-1).
The maximum slope of operation varies depending on the conditions under which the
machine is being operated. These conditions include the terrain (e.g., wet, muddy, dry,
compacted, rocky), the direction of the machine operation (e.g., cross-slope, uphill,
downhill, diagonally across the slope), and the operation being performed. OSHA is
revising the final rule to require that employers assure that machine operators follow the
instructions, directions and limitations described by the manufacturer in the operating
and maintenance manuals.
There are many ways in which an employer can accomplish this obligation. Manufacturers'
operating instructions can be incorporated into operator training programs. Compliance
with these operating instructions can be reinforced during regular safety and health
meetings, and through spot checks on employees' operating performance.
