{¶ 8} Trousdale, Byington, and Thomas Mock, Byington Builders' "lead man" on the job, all testified that on the day that Trousdale fell, no catch platforms had been installed and no safety belts, harnesses, or lifelines were being used by anyone working on the apartment roof. Byington admitted that he did not require his employees to use safety harnesses and that *912he was aware that no one was using safety equipment on this job. He testified, "[A] lot of times when you do have these harnesses and ropes, you trip and fall over it nonstop. And people weren't comfortable-don't get comfortable with them. I've seen more accidents with that. I've had more accidents with them on than I have without them." Both Mock and Tyson Pengob, another Byington Builders supervisor, testified that they had never instructed anyone on the job site that using safety equipment was required. The day that Trousdale fell, Mock and Pengob were both working on the roof without any safety equipment.
{¶ 9} Trousdale testified that a few days before he fell, another Byington Builders employee fell from the same roof and landed on an apartment balcony. According to Trousdale, Byington Builders made no changes in the use of safety equipment after this incident. Coworker Rodney Clift, a fellow union carpenter, also testified that an employee fell from the roof and landed on a balcony. Byington Builders presented no testimony or other evidence at the hearing disputing the fact that another employee fell from the same roof a few days before Trousdale did.
{¶ 10} The parties presented conflicting testimony about whether any safety harnesses and lifelines were available at the job site. Byington, Mock, and Pengob all testified that they had made Trousdale aware that safety harnesses and lifelines were kept in an equipment trailer that, according to Byington, was located ten feet from the building from which Trousdale fell. By contrast, Trousdale testified that he never saw the trailer or any harnesses, ropes, lanyards, or roofing brackets on the job site and that neither Byington nor any supervisor ever told him that he was required to get safety equipment from a trailer. Clift also testified that he never saw a trailer or any safety equipment at the job site.
3. Order
{¶ 11} In the commission's order, mailed on November 20, 2014, the SHO denied Trousdale's VSSR application in part and granted it in part. The SHO found that Ohio Adm.Code 4123:1-3-09(F)(1) applied to the roof from which *38Trousdale fell, that Byington Builders had violated it, and that the violation was the proximate cause of Trousdale's injuries.
{¶ 12} The SHO resolved the factual dispute regarding the availability of the safety equipment in Byington Builders' favor but found that "[e]ven when construing the evidence in favor of the Employer, [i.e.,] that the safety equipment was on-site and that the Injured Worker knew of its availability," Byington Builders still violated the provision. Mere availability did not suffice, because "[e]ven assuming safety belts were available, [Ohio Adm.Code] 4123:1-3-09(F)(1) requires that they be 'attached to a lifeline which is securely fastened to the structure' in order to satisfy the requirement of being used 'in lieu of a catch platform.' " Accordingly, the SHO found that "the Employer has the option to either install a catch basin [sic: platform] or to fasten a lifeline to the roof so that those wishing to use a safety belt would have something to attach the safety belt to on the structure," and "[t]he employer in the instant case did not install either of those devices."
{¶ 13} The SHO awarded additional compensation in the amount of 40 percent of Trousdale's maximum weekly rate due to this VSSR, finding that the violation was serious and noting that another worker had fallen off the same roof a few days before Trousdale fell.
*9134. Motion for a Rehearing
{¶ 14} Byington Builders moved for a rehearing, arguing that Ohio Adm.Code 4123:1-3-09(F)(1) must be read in conjunction with Ohio Adm.Code 4123:1-3-03(J)(1) and that under the latter provision, which relates to personal protective equipment, it is the responsibility of the employee, not the employer, to use a safety harness. Byington Builders argued that the proximate cause of Trousdale's injuries was his own "unilateral negligence" in failing to use the lifelines that Byington Builders claimed it had made available. It further argued that securely fastening a lifeline to the structure would have done nothing to prevent injury, because workers may have failed to use the available lifeline. A different SHO denied the motion for a rehearing, finding that Byington Builders had not submitted any new and relevant evidence nor shown that the original order was based on an obvious mistake of fact or clear mistake of law.
C. Byington Builders' Mandamus Action
{¶ 15} In April 2015, Byington Builders filed its mandamus complaint asking the Tenth District Court of Appeals to issue a writ directing the commission to vacate its prior decisions and to enter an order denying Trousdale's request for a VSSR award. In support of its claim that the commission abused its discretion, Byington Builders again asserted that it had not violated Ohio Adm.Code 4123:1-3-09(F)(1), because that rule, when read in conjunction with *39Ohio Adm.Code 4123:1-3-03(J)(1), required it to do no more than make lifelines and safety harnesses available for employees and did not require Byington Builders to affix either catch platforms or lifelines to the building, as the SHO had ruled. Byington Builders again asserted that the proximate cause of Trousdale's injuries was his own unilateral negligence in failing to use available safety harnesses. Byington Builders additionally asserted that the commission failed to strictly construe Ohio Adm.Code 4123:1-3-09(F)(1) and to resolve all reasonable doubts regarding its interpretation in favor of the employer as required by this court's caselaw.
{¶ 16} A Tenth District magistrate recommended that the court deny the writ. 2017-Ohio-2623, 2017 WL 1650151, at ¶ 51. Taking guidance from State ex rel. Avalotis Painting Co. v. Indus. Comm. , 91 Ohio St.3d 137, 742 N.E.2d 1124 (2001), in which this court discussed Ohio Adm.Code 4123:1-3-03(J)(1), the magistrate concluded that under Ohio Adm.Code 4123:1-3-09(F)(1), "logic requires the conclusion that the employer bear the responsibility of rigging the lifeline. It is not the responsibility of the worker to rig his own lifeline or to request that his employer rig a lifeline." 2017-Ohio-2623 at ¶ 47. Because it was undisputed that Byington Builders failed to install a catch platform or rig a lifeline and had therefore violated Ohio Adm.Code 4123:1-3-09(F)(1), the magistrate further concluded that "neither proximate cause nor unilateral negligence are truly issues." Id. at ¶ 48.
{¶ 17} Byington Builders objected to the magistrate's recommendation, reiterating its prior arguments and asserting that the facts in Avalotis are distinguishable from those in this case. The Tenth District overruled Byington Builders' objections and adopted the magistrate's decision as its own. Byington Builders filed a timely appeal of the Tenth District's judgment.
III. ANALYSIS
A. Requirements for a VSSR Award
{¶ 18} "An award for a VSSR is 'a new, separate, and distinct award' over and above standard workers' compensation benefits. It is not covered by an employer's *914workers' compensation premium." State ex rel. Precision Steel Servs., Inc. v. Indus. Comm. , 145 Ohio St.3d 76, 2015-Ohio-4798, 47 N.E.3d 109, ¶ 15, quoting State ex rel. Newman v. Indus. Comm. , 77 Ohio St.3d 271, 272, 673 N.E.2d 1301 (1997). "To be entitled to an additional award for a VSSR, a claimant must show that (1) a specific safety requirement applied, (2) the employer violated that requirement, and (3) the employer's violation caused the injury." Id.
B. Requirements for a Writ of Mandamus
{¶ 19} To prevail on its claim for mandamus relief, Byington Builders must "demonstrate that the commission's decision to issue a VSSR award was an abuse *40of discretion. So long as some evidence supports the commission's order, there was no abuse of discretion, and the court must uphold the decision." State ex rel. Armstrong Steel Erectors, Inc. v. Indus. Comm. , 144 Ohio St.3d 243, 2015-Ohio-4525, 41 N.E.3d 1233, ¶ 13. "The interpretation of a specific safety requirement is within the final jurisdiction of the commission and may be corrected in mandamus only upon a showing that the commission abused its discretion." Precision Steel at ¶ 21. "[B]ecause a VSSR award is a penalty imposed on an employer, specific safety requirements must be strictly construed and all reasonable doubts concerning the interpretation of a particular safety regulation must be resolved in favor of the employer." Id.
C. The Industrial Commission Did Not Abuse Its Discretion
1. The Specific Safety Requirement Applied
{¶ 20} Chapter 4123:1-3 of the Ohio Administrative Code applies to the construction and repair of buildings. Ohio Adm.Code 4123:1-3-01(A). And Ohio Adm.Code 4123:1-3-09(F)(1) applies to work performed on "pitched roofs with a rise of four inches in twelve or greater, sixteen feet or more above ground, and not having a parapet of at least thirty inches in height." It is undisputed that when Trousdale fell, he was engaged in construction activity: the installation of roof caps. It is likewise undisputed that the roof from which Trousdale fell had a pitch of at least 6 inches in 12 (which is greater than 4 inches in 12), was 22 feet above the ground, and had no parapet. The rule therefore applied to the job site at which Trousdale was injured. Accord State ex rel. R. Bauer & Sons Roofing & Siding, Inc. v. Indus. Comm. , 84 Ohio St.3d 62, 69, 701 N.E.2d 995 (1998) (" Ohio Adm.Code 4121:1-3-09 operates to protect any construction employee who works with pitched roofs, flat roofs, or any other roofing device mentioned in the rule, and who is injured due to an employer's failure to comply with the duties imposed").
2. Byington Builders Violated the Specific Safety Requirement
a. The Requirements of Ohio Adm.Code 4123:1-3-09(F)(1)
{¶ 21} This case hinges on what Ohio Adm.Code 4123:1-3-09(F)(1) required of Byington Builders. The commission and the Tenth District concluded that it required Byington Builders to install either catch platforms or lifelines. Byington Builders argues that Ohio Adm.Code 4123:1-3-09(F)(1) must be read in conjunction with Ohio Adm.Code 4123:1-3-03(J)(1) and that read together, these sections required Byington Builders to merely make lifelines and safety harnesses available to employees. The Tenth District relied on Avalotis -a case that turned on the construction of Ohio Adm.Code 4123:1-3-03(J)(1) and that did not involve the application *915or interpretation of Ohio Adm.Code 4123:1-3-09(F)(1) -to hold that it *41was the employer's responsibility to install lifelines, not merely make them available.
i. The plain text of Ohio Adm.Code 4123:1-3-09(F)(1) resolves the issue
{¶ 22} Ohio Adm.Code 4123:1-3-09(F)(1) states: "On pitched roofs with a rise of four inches in twelve or greater, sixteen feet or more above ground, and not having a parapet of at least thirty inches in height, catch platforms shall be installed. * * * Safety belts or harnesses attached to a lifeline which is securely fastened to the structure may be used in lieu of a catch platform." (Emphasis added.) The first sentence of this rule clearly requires employers whose employees are engaging in construction activity on qualifying roofs to install catch platforms. See Ohio Adm.Code 4123:1-3-01(B)(25) (" 'Shall' shall be considered mandatory"); see also Bauer & Sons , 84 Ohio St.3d at 69, 701 N.E.2d 995. The last sentence of the rule provides that "in lieu of" the required catch platform, safety belts or harnesses that are attached to a lifeline that is securely fastened to the structure may be used . Said another way, if "[s]afety belts or harnesses attached to a lifeline which is securely fastened to the structure" are not used, catch platforms shall be installed. See State ex rel. Danstar Builders, Inc. v. Indus. Comm. , 108 Ohio St.3d 315, 2006-Ohio-1060, 843 N.E.2d 761, ¶ 4 (the rule provides that "pitched roofs require a catch platform unless safety belts and lifelines are used"). Ohio Adm.Code 4123:1-3-09(F)(1) therefore required Byington Builders to install catch platforms if safety harnesses attached to securely fastened lifelines were not used.
{¶ 23} Because Byington Builders admits that it did not install catch platforms, the question becomes whether safety harnesses attached to securely fastened lifelines were used. This depends on what "used" means. "Use" is not a defined term in the applicable division of the Ohio Administrative Code, so this court must afford the word its common meaning. State ex rel. Parks v. Indus. Comm. , 85 Ohio St.3d 22, 25, 706 N.E.2d 774 (1999) (" 'The [commission's] rules for specific safety requirements have the effect of legislative enactments' and therefore are 'subject to the ordinary rules of statutory construction' " [brackets sic] ), quoting State ex rel. Miller Plumbing Co. v. Indus. Comm. , 149 Ohio St. 493, 496-497, 79 N.E.2d 553 (1948) ; R.C. 1.42 ("[w]ords and phrases shall be * * * construed according to * * * common usage").
{¶ 24} The dictionary definition of the verb "use" is "to put into action or service * * * EMPLOY ." Webster's Third New International Dictionary 2523 (2002). Byington Builders would have "use" mean "make available." But the safety-and-hygiene rules already have a word with that definition: " 'Provide' means to make available," Ohio Adm.Code 4123:1-3-01(B)(21). If the drafters of the code had intended Ohio Adm.Code 4123:1-3-09(F)(1) to require employers to install catch platforms unless safety belts, harnesses, and lifelines were merely *42made available , they would have employed the word to which they had given that definition. See, e.g. , Ohio Adm.Code 4123:1-3-04(D)(1), (2), and (3), 4123:1-3-10(R)(6), 4123:1-3-10(V)(3), and 4123:1-3-10(Y)(7). Indeed, Ohio Adm.Code 4123:1-3-18(H)(2)(b) says, "When entering a toxic or flammable atmosphere, an employee shall be provided with and use an adequate, attended, lifeline." (Emphasis added.) The code drafters' employment of both "use" and "provide" in that rule bolsters our conclusion that "use" does not mean the same thing as "provide."
{¶ 25} Because the applicable rule employs the word "used" rather than the *916word "provided," Byington Builders was required to install catch platforms if safety belts or harnesses attached to lifelines that were securely fastened to the structure were not used-i.e., put into action or service.
ii. The plain meaning of the rule is consistent with the commission's interpretation, which is not "patently illogical"
{¶ 26} This court is "normally obligated to defer to the commission's interpretation of its own rules," State ex rel. Lamp v. J.A. Croson Co. , 75 Ohio St.3d 77, 79-80, 661 N.E.2d 724 (1996), and this straightforward reading of the text of Ohio Adm.Code 4123:1-3-09(F)(1) is consistent with the SHO's interpretation of the rule's requirements. The SHO stated, "Even assuming safety belts were available, [Ohio Adm.Code] 4123:1-3-09(F)(1) requires that they be 'attached to a lifeline which is securely fastened to the structure' in order to satisfy the requirement of being used 'in lieu of a catch platform.' " (Emphasis added.)
{¶ 27} While "[t]he commission has the discretion to interpret its own rules * * *, where the application of those rules to a unique factual situation gives rise to a patently illogical result, common sense should prevail." State ex rel. Harris v. Indus. Comm. , 12 Ohio St.3d 152, 153, 465 N.E.2d 1286 (1984), abrogated on other grounds , State ex rel. AK Steel Corp. v. Davis , 123 Ohio St.3d 458, 2009-Ohio-5865, 917 N.E.2d 797. Citing this principle, Byington Builders argues that it is illogical to require an employer to install lifelines that an employee might choose not to use.
{¶ 28} However, we are not convinced that Byington Builders' situation is unique or that the application of Ohio Adm.Code 4123:1-3-09(F)(1) to that situation would be illogical. While Trousdale's fall was surely of unique importance to him, Byington Builders has identified-and the record discloses-nothing about this particular roofing job or this particular accident that was unique in a way that should abrogate the application of a specific safety requirement. And, Byington Builders' argument that it is illogical to require employers to install lifelines that might go unused would make sense only if this court agreed with Byington Builders' flawed reading of Ohio Adm.Code 4123:1-3-09(F)(1). Byington Builders has not explained how it is illogical to apply the *43straightforward requirements of this rule regarding roofing devices to this straightforward roofing job.
iii. Ohio Adm.Code 4123:1-3-03(J)(1) does not alter the requirements of Ohio Adm.Code 4123:1-3-09(F)(1)
{¶ 29} Byington Builders' primary argument is that Ohio Adm.Code 4123:1-3-09(F)(1) must be read in conjunction with Ohio Adm.Code 4123:1-3-03(J)(1), and that the latter rule permitted Byington Builders to comply with the former rule by making safety harnesses and lifelines available for employees to use. Byington Builders is incorrect.
{¶ 30} Ohio Adm.Code 4123:1-3-03(J)(1) states:
Lifelines, safety belts or harnesses and lanyards shall be provided by the employer, and it shall be the responsibility of the employee to wear such equipment when exposed to hazards of falling where the operation being performed is more than six feet above ground or above a floor or platform, except as otherwise specified in this chapter , and when required to work on stored material in silos, hoppers, tanks, and similar storage areas. Lifelines and safety belts or harnesses shall be securely fastened to the structure and shall sustain a static load *917of no less than three thousand pounds.
(Emphasis added.) This is a general rule relating to personal protective equipment. By contrast, Ohio Adm.Code 4123:1-3-09(F)(1) is a more specific rule relating to work performed on pitched roofs that are at least 16 feet above the ground.
{¶ 31} R.C. 1.51 states:
If a general provision conflicts with a special or local provision, they shall be construed, if possible, so that effect is given to both. If the conflict between the provisions is irreconcilable, the special or local provision prevails as an exception to the general provision, unless the general provision is the later adoption and the manifest intent is that the general provision prevail.
{¶ 32} Here, it is possible to give effect to both Ohio Adm.Code 4123:1-3-03(J)(1) and 4123:1-3-09(F)(1). The two rules have different (though sometimes overlapping) scopes and are not in conflict. Ohio Adm.Code 4123:1-3-03(J)(1) applies to operations being performed more than six feet above the ground or *44above a floor or platform-whether on a roof or in any other workspace. In such cases, the employer is required to "provide"-i.e., make available-lifelines, safety belts or harnesses, and lanyards, and it is the "responsibility of the employee to wear such equipment." Id. The rule expressly applies "except as otherwise specified in this chapter." Id.
{¶ 33} Ohio Adm.Code 4123:1-3-09(F)(1) otherwise specifies. It applies a more stringent requirement to operations being performed on pitched roofs that are more than 16 feet above the ground. In those cases, the employer is required to install catch platforms unless "safety belts or harnesses attached to a lifeline which is securely fastened to the structure" are "used," id. , i.e., put into action or service. The general requirements in Ohio Adm.Code 4123:1-3-03(J)(1) do not alter anything in this more specific requirement. And even if the two rules did conflict, under R.C. 1.51, the more specific provision would prevail.
{¶ 34} For these reasons, the Tenth District's focus on Avalotis , 91 Ohio St.3d 137, 742 N.E.2d 1124 -and Byington Builders' attempts to distinguish it-are misplaced. In Avalotis , a painter stood on a narrow I-beam, without a lifeline, in order to paint the beam above. He lost his balance and fell four stories. This court considered the only rule at issue-the predecessor to Ohio Adm.Code 4123:1-3-03(J)(1) -and determined that it required the employer, not the employee, to rig a lifeline when that rule required one to be provided, because the rule made the employee responsible only for equipment that was worn (i.e., safety harnesses but not lifelines) and because a lifeline was "useless if it [wa]s not in place for the employee to tie off." Avalotis , 91 Ohio St.3d at 139, 742 N.E.2d 1124. While it is instructive that even under the less-stringent requirements of Ohio Adm.Code 4123:1-3-03(J)(1), this court faulted the employer for failing to rig a lifeline, that decision does not control the outcome of this case, which hinges on the application of a different, more specific rule.
b. Byington Builders Violated Ohio Adm.Code 4123:1-3-09(F)(1)
{¶ 35} It is undisputed that (1) Byington Builders required Trousdale to work on a roof with a pitch greater than four inches in twelve, that was more than 16 feet from the ground, and that had no parapet, (2) Byington Builders did not install catch platforms, and (3) safety belts or harnesses *918attached to a lifeline that was securely fastened to the structure were not used. Byington Builders therefore violated Ohio Adm.Code 4123:1-3-09(F)(1). Accord Danstar Builders , 108 Ohio St.3d 315, 2006-Ohio-1060, 843 N.E.2d 761, at ¶ 4, 9, 16.
3. Byington Builders' Violation Proximately Caused Trousdale's Injuries
a. Evidence Supports The Commission's Finding of Probable Cause
{¶ 36} The commission did not abuse its discretion by finding that Byington Builders' compliance with Ohio Adm.Code 4123:1-3-09(F)(1)"would have prevented *45the fall from the roof." Evidence in the record indicates that Trousdale slipped while walking on the roof, slid down its surface, and went over the edge. His fall to the ground caused his injuries. Had catch platforms been installed or had safety harnesses attached to a lifeline securely fastened to the roof been used, Trousdale's fall would have been arrested.
b. The "Unilateral Negligence" Defense Is Inapplicable
{¶ 37} Byington Builders argues that the proximate cause of Trousdale's injuries was his own "unilateral negligence in failing to utilize the available safety equipment" and that under State ex rel. Frank Brown & Sons, Inc. v. Indus. Comm. , 37 Ohio St.3d 162, 524 N.E.2d 482 (1988), Trousdale's negligence precludes his receipt of a VSSR award.
i. Byington Builders' VSSR bars its assertion of unilateral negligence
{¶ 38} In Frank Brown & Sons , this court held that an injured worker's "unilateral negligence in removing the top cross brace" from a scaffold "without first installing a corresponding cross brace beneath, contrary to instructions" precluded his receipt of a VSSR award. Id. at 164, 524 N.E.2d 482. In its analysis, this court recounted the facts of State ex rel. Lewis v. Indus. Comm. , Franklin App. No. 83AP-756, 1984 WL 4703 (Mar. 15, 1984), in which the injured worker had "voluntarily switched off a punch press safety device despite specific rules to the contrary," leading to his injury. Frank Brown & Sons at 164, 524 N.E.2d 482. The court of appeals had "denied the writ seeking a VSSR award, finding that the employer had fully complied with the applicable safety regulations and the claimant's unilateral act violated the safety requirement." Id. The court of appeals in Frank Brown & Sons then concluded, "Here, too, the scaffold was properly assembled and in compliance with the applicable safety requirement until appellee's removal of the cross brace." Id.
{¶ 39} These cases illustrate the rule that dispatches Byington Builders' unilateral-negligence argument-i.e., that this defense "is available only if the employer first complies with the applicable safety requirement ." (Emphasis added.) State ex rel. Glunt Industries, Inc. v. Indus. Comm. , 132 Ohio St.3d 78, 2012-Ohio-2125, 969 N.E.2d 252, ¶ 16 (despite injured worker's statement that he did not need any safety equipment to perform the task he was set to complete, employer could not take advantage of unilateral-negligence defense since it did not satisfy VSSR requiring it to provide electrical-safety equipment).
{¶ 40} As this court has explained, "the defense is not actually about an employee's negligence . The employer instead avoids VSSR liability when '[the] employee unilaterally violates a safety requirement,' " (emphasis sic)
*919State ex rel. Quality Tower Serv., Inc. v. Indus. Comm. , 88 Ohio St.3d 190, 193, 724 N.E.2d 778 (2000), quoting *46State ex rel. Cotterman v. St. Marys Foundry , 46 Ohio St.3d 42, 544 N.E.2d 887 (1989) (granting writ to vacate VSSR award where employee used his own ultra-light straps to rig a support structure in contravention of direct instructions from employer to use employer-provided straps that complied with the safety requirement). "[A]n employee's negligence in failing to protect himself from injury due to an employer's VSSR will never bar recovery," id. , because specific safety requirements are " 'intended to protect employees against their own negligence and folly as well as to provide them a safe place to work,' " Cotterman at 47, 544 N.E.2d 887, quoting State ex rel. U.S. Steel Corp. v. Cook , 10 Ohio App.3d 183, 186, 461 N.E.2d 916 (10th Dist.1983) (granting writ to vacate commission's order denying VSSR award, despite employer's argument that decedent was supervisor responsible for selecting chains to suspend the load that fell on him).
{¶ 41} Because Byington Builders failed to comply with Ohio Adm.Code 4123:1-3-09(F)(1), it cannot employ the defense that Trousdale was unilaterally negligent.
ii. Trousdale was not unilaterally negligent
{¶ 42} Moreover, even if the applicable rule had required Byington Builders to do no more than make safety equipment available to Trousdale and Byington Builders had done so, this case does not fit the mold of those that have allowed employers to avoid a VSSR award due to the injured worker's unilateral negligence. This is not a case in which a rogue employee disregarded direct instructions to use certain safety equipment or disabled an employer-provided safety device. Compare Frank Brown & Sons , 37 Ohio St.3d 162, 524 N.E.2d 482 ; Lewis , Franklin App. No. 83AP-756, 1984 WL 4703 ; Quality Tower Serv . To the contrary, Byington Builders' owner and supervisors never instructed any employees to use safety equipment and no employees-including the two supervisors-were using any safety equipment on this job, with the approval of the owner.
{¶ 43} Accordingly, Trousdale's failure to use safety equipment was hardly unilateral, and Byington Builders' claim that Trousdale was negligent makes little sense. Byington Builders casts the decision to leave safety equipment in the equipment trailer on this particular job as the educated decision of experienced roofers. In light of this position, Byington Builders' argument that Trousdale was negligent implies that its entire crew, including its supervisors and owner, were also acting negligently.
{¶ 44} Had Byington Builders required its crew to use safety harnesses attached to lifelines that were securely attached to the structure and had Trousdale alone, unbeknownst to Byington Builders, failed to heed that instruction, we would likely view this case differently. As it is, because Byington Builders failed to comply with the applicable specific safety requirement and *47because Trousdale's actions did not constitute unilateral negligence, the defense is inapplicable.
IV. CONCLUSION
{¶ 45} For the reasons above, the commission did not abuse its discretion in granting Trousdale a VSSR award, and the Tenth District correctly denied Byington Builders' request for a writ of mandamus. We affirm the Tenth District's judgment.
Judgment affirmed.
