|OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov.|
(A) It is the activity to be performed, not the company's standard industrial classification (SIC) code, that determines whether the construction standard applies;Unifying Parts 1910 and 1926
(B) "Maintenance" means keeping equipment or a structure in proper condition through routine, scheduled or anticipated measures without having to significantly alter the structure or equipment in the process. For equipment, this generally means keeping the equipment working properly by taking steps to prevent its failure or degradation.
(C) Whether repairs are maintenance or construction depends on the extent of the repair and whether the equipment is upgraded in the process.
Example No. 1: Maintenance
Five percent of a company's utility lines are downed in a storm and are repaired or replaced. In so doing, the service is restored, with the same capacity and capabilities it had before the damage. This is maintenance work because only a small part of the total system is repaired or replaced and the work returns the system to its original condition.
Example No. 2: Construction
Three quarters of a company's lines are damaged and replaced. This is construction because the work is done to a very large portion of the total system.
Example No. 3: Construction
A few lines are changed to upgrade service. This is construction work because this part of the system, though only a very small portion, is improved relative to its condition before the work was done.
Example No. 4: Maintenance
A small water shut-off valve in a large, complex chemical processing system is removed and replaced. Its replacement is part of the routine maintenance of the system and removing and replacing the valve is done without making major alterations to the rest of the system. The removal and replacement of the valve would be considered maintenance.
Example No. 5: Construction
A 36-inch valve that is one of three major components in a processing system is removed and replaced. To do the job, about half of all the parts in the system have to be cut, unbolted, moved, or otherwise altered or replaced. Removing and replacing this valve would be considered construction because the valve constitutes a major portion of the equipment it is in and a significant portion of the system's parts must be moved or altered in the process of doing the job.
