Factors to consider when establishing the maximum <br />speed limit shall include the width, slope and alignment of the road, the type of <br />equipment using the road, the road material, and any hazardous conditions <br />which may exist. <br />(5) Road surface traction is not impaired by weather conditions, such as sleet and <br />snow, unless corrective measures are taken to improve traction. <br />(e) This standard is not applicable to rail beds. <br />There is no MSHA policy for this standard. <br />77.1605(k) <br />Berms or guards shall be provided on the outer bank of elevated roadways. <br />MSHA policy can be found here: 77.1605(k) <br />These standards require that adequate berms or guardrails be installed on roadways <br />where a drop-off exists of sufficient grade or depth to cause a vehicle to overturn or <br />endanger persons in equipment. It also establishes requirements for the height and <br />construction of berms and guardrails (metal and nonmetal). Alternative measures, <br />other than berms; may be utilized for roadways that are infrequently traveled or used <br />only by service or maintenance vehicles (metal and nonmetal). <br />Issues to Consider in Determining Compliance: <br />http://www.msha.gov/STATS/Top2OViols/tips/9300.htm 11/12/2015 <br />
