(b) When ber core wire rope slings are to be used at temperatures below -40 oF (-40 oC), the sling manufacturer should be consulted. (c) When IWRC wire rope slings are to be used at temperatures above 400 oF (204 oC) or below -40 oF (-40 oC), the sling manufacturer should be consulted. OSHA 1910.184 (f) Wire Rope Slings [§1910.184(f)(3)] Safe operating temperatures. Fiber core wire rope slings of all grades shall be permanently removed from service if they are exposed to temperatures in excess of 200 °F. When non- ber core wire rope slings of any grade are used at temperatures above 400 °F or below minus 60 °F, recommendations of the sling manufacturer regarding use at that temperature shall be followed. OSHA 1926.251 (c) Wire Rope [§1926.251(c)(14)] Safe operating temperatures. Fiber core wire rope slings of all grades shall be permanently removed from service if they are exposed to temperatures in excess of 200 °F (93.33 °C). When non ber core wire rope slings of any grade are used at temperatures above 400 °F (204.44 °C) or below minus 60 °F (15.55 °C), recommendations of the sling manufacturer regarding use at that temperature shall be followed.
