What standard covers guarding of calendar stacks?

Section 1910.261(k)(18) addresses the hazard of nip points on calender rolls and gives alternatives as to the method of eliminating or minimizing this hazard. The abatement methods listed in the standard would be acceptable so long as exposure to the hazard is eliminated or minimized. The standard contained in 1910.261(k)(18) is specific to the hazard of nip points on all calender rolls in pulp, paper, and paperboard mills. However, nip point hazards, when paper is not being fed into the calender stack rolls, shall be guarded in accordance with a general standard such as 1910.212, which does apply in such a situation.
