Subpart W: Rollover Protective Structures; Overhead Protection
1926.1000. This section provides the safety requirements of different types of material-
handling equipment with regard to rollover protection. It applies to rubber-tire scrapers,
loaders, dozers, agricultural and industrial tractors, crawler tractors, etc.
1926.1001. This section gives the minimum performance criteria for rollover protective
structures for designated scrapers, loaders, dozers, graders, and crawler tractors.
Laboratory test procedures and performance requirements to determine the adequacy of
structures to protect the operators are provided.

1926.1002. Safety requirements of protective frames are given for wheel-type agricul-
tural and industrial tractors used in construction.
1926.1003. This section deals with overhead protection for operators of agricultural and
industrial tractors.

AMERICAN NATIONAL STANDARDS

The American National Standards Institute is a voluntary nonprofit organization engaged
in promoting consensus voluntary standards for the industry. The American National
Standards Institute does not develop standards. It rather helps other associations, societies,
and interested bodies to develop standards to fulfill the demands of the industry. After the
standard has been developed, the American National Standards Institute simply adopts it,
provided the criteria for the development of standards have been met. As a condition for
adoption by ANSI, the standard developer must demonstrate that during the development
phase, “consensus, due process, and openness” have been adhered to. Consensus does not
necessarily mean unanimity among members but implies that all objections, comments,
reservations, and negative votes have been properly discussed and addressed, and all stake-
holders who are affected by the activity were able to review the standard and an open envi-
ronment was provided during its development. Once ANSI adopts a standard, it becomes
an industry standard. Currently, ANSI has 33 standards relating to construction, and 11
standards are in the development stage for construction.
