Mac Rak and RMI and OSHA Pallet Rack Standards

RMH/ANSI 16.1 and Mac Rak’s position on OSHA’s Rack Repair Regulations

When OSHA lacks expertise on a particular subject matter or when OSHA lacks detailed regulations regarding a specific industrial practice, such as in the case of pallet rack repair, OSHA often turns to the recognized governing body expert in that particular field for guidance.  Regarding rack repair, that expert resource in the United States is the Rack Manufacturer’s Institute (RMI) of which Mac Rak is a member. This is America’s trade association comprised of all major pallet rack producers. RMI’s main engineering document RMH/ANSI 16.1 addresses the topic of pallet rack repair and so this document is used by OSHA as a general guideline regarding pallet rack repair.

Mac Rak's commitment to engineering standards lead it to become a founding member of RMI the Rack Manufactures Institute.

The following is an excerpt of the applicable  passages in ANSI 16.1 regarding pallet rack repair:

  • The storage rack system operator is responsible for the maintenance and repair of storage systems.
  • Upon visible damage, the pertinent portions of the rack shall be unloaded immediately and removed from service by the user until the damaged portion is repaired or replaced.
  • Rack repairs must provide that the repaired frame be as strong or stronger than the original frame as currently used in that system.
  • Rack repairs need to be performed by qualified installers.
  • Altering / modifying components without the direction of a supervisory engineer is not allowed and will lead to rack failure.

Our Products and Standards Meet or Exceed All Engineering Requirements in RMH/ANSI 16.1

Since its inception, Mac Rak’s culture and process has centered on attaining engineered review and approval. For decades, Mac Rak has worked closely with P.E. experts in the field of pallet racking to ensure that we superseded basic performance criteria related to things such as column axial force, torsional buckling, column splice strength, brace continuity, the list goes on and on.

Every phase of Mac Rak’s offering, from our inspection criteria, to the design and construction of our repair and protection product to our installation procedures all meet or exceed every engineering requirements in ANSI 16.1 related to pallet rack repair.

In conclusion, OSHA’s only applicable (single) regulation distantly related to pallet rack repair is their all-encompassing General Duty Clause, Section 5(a)(1) of the Occupational Safety and Health Act (OSHA) of 1970.  This regulation requires employers to provide their employees with a place of employment that "is free from recognizable hazards that are causing or likely to cause death or serious harm to employees."  OSHA recognizes that this single regulation is not focused enough on the specific and unique dangers of damaged pallet racking. Therefore, OSHA defers to the RMI ANSI 16.1 specification regarding pallet rack repair to guide their inspections of pallet rack repair.
