Before RIGGS, P.J., and LANDAU and LEESON, JJ.
LEESON, Judge.
Claimant seeks review of a Workers' Compensation Board order that reinstated K-Mart Corporation's denial of his claim. O.R.S. 656.298. The question is whether K-Mart is responsible under O.R.S. 656.029(1) for providing workers' compensation coverage for claimant. The Board concluded that it is not.
Claimant worked for a company that contracted with K-Mart to provide janitorial services. Claimant was injured while cleaning one of K-Mart's stores. O.R.S. 656.029(1) requires that
"If a person awards a contract involving the performance of labor where such labor is a normal and customary part or process of the person's trade or business, the person awarding the contract is responsible for providing workers' compensation insurance coverage for all individuals * * * who perform labor under the contract * * *." (Emphasis supplied.)
Claimant and intervenor correctly point out that the Board's order does not show whether it considered OAR XXX-XXX-XXXX(4)(c), which interprets the phrase "normal and customary part or process of the person's trade or business" to mean "the day-to-day activities or operations which are necessary to successfully carry out the business or trade." The Department of Consumer and Business *338 Services promulgated that rule pursuant to O.R.S. 656.726(3). Properly promulgated administrative rules have the force of law. Bronson v. Moonen, 270 Or. 469, 476, 528 P.2d 82 (1974). Accordingly, we remand to the Board to consider the facts of this case in the light of that rule.
Because of this disposition, we need not address respondent's cross-assignment of error.
Reversed and remanded.
