Sling Proof Testing Regulations

Proof Test for Slings

For companies that utilize overhead cranes and lifting equipment in daily operations, it is essential that each part of the machine stay in good working order. To increase the safety and productivity of this equipment, OSHA requires that all employers proof test any and all alloy steel chain slings and all of its components before putting it into use.

OSHA 1910.184(e)(4) Sling Inspections
(the following excerpt taken directly from OSHA 1910.184)

Proof testing. The employer shall ensure that before use, each new, repaired, or reconditioned alloy steel chain sling, including all welded components in the sling assembly, shall be proof tested by the sling manufacturer or equivalent entity, in accordance with paragraph 5.2 of the American Society of Testing and Materials Specification A391-65, which is incorporated by reference as specified in Sec. 1910.6 (ANSI G61.1-1968). The employer shall retain a certificate of the proof test and shall make it available for examination.
