Multiple Lift Rigging Procedures
Greetings, I hope everyone is having a good season so far. This month’s safety corner is on “Multiple Lift Rigging Procedures”, found in OSHA, 29 CFR 1926.753(e) under subpart R, Steel Erection.
There has been discussion about this topic out on the jobsites recently and some guidance has been provided from OSHA on this topic. Examples of some of the multiple lift tasks that were discussed included, lifting loads from each hook on a 2-way or 4-way spreader assembly connected to the crane hook block or hook ball, such as bundles of rebar, gang boxes, portable toilets, etc. The OSHA standard that covers multiple lift rigging can be found in 29CFR 1926.753(e). This standard in the OSHA regulation is for hoisting during “Steel Erection only”. The regulation states “Only steel beams and similar structural members can be lifted”, (1926.753(e)(I)(iii). This topic is also broken down further in the Federal Register under Safety Standards for Steel Erection, paragraph(e)(1)(iii).
Some of the other requirements in the steel erection standards include the following:
- Employees engaged in a multiple lift operation, must be trained in accordance with 1926.761(c)(1)
- Employers that perform multiple lift rigging, must use multiple lift rigging assemblies that are assembled and designed for a specified capacity. The assembly must be rigged and have at least 7’ of separation between members
- Paragraph(e)(1)(v) in the federal register, prohibits the use of a crane in a multiple lift if the crane manufacturer recommends that the crane can not be used for that purpose.
OSHA is in the process of administering a “Regional Emphasis Program” on cranes in the New England region and this is one of the topics that will be focused on. Enforcement will begin in this region after a press release to the Boston Building Trades.
As always, stay safe out on the jobsites and enjoy the summer!
