avoidable perils. Moles v. Kansas City Stock Yards Co. of Maine, 434 S.W.2d 752, 755 (Mo.App.1968). Whether the employer has fulfilled its duty depends upon the facts of each case. Lathrop v. Rippee, 432 S.W.2d 227, 231 (Mo.1968). For example, in McDaniel v. Kerr, 258 S.W.2d 629 (Mo. banc 1953), the employer had failed to provide a safe workplace where the employee’s inhalation of dust on the job caused damage requiring removal of his lung. In DeMarco v. United States, 204 F.Supp. 290 (E.D.N.Y.1962), the court found a negligent failure to provide a safe working environment where the plaintiff was injured when he fainted and fell after complaining about gasoline fumes in an unventilated work area.
The allegations of the instant case, taken as true, show that the tobacco smoke of co-workers smoking in the work area is hazardous to the health of employees in general and plaintiff in particular. The allegations also show that defendant knows the tobacco smoke is harmful to plaintiff’s health and that defendant has the authority, ability, and reasonable means to control smoking in areas requiring a smoke-free environment. Therefore, by failing to exercise its control and assume its responsibility to eliminate the hazardous condition caused by tobacco smoke, defendant has breached and is breaching its duty to provide a reasonably safe workplace. See Shimp v. New Jersey Bell Telephone Co., 145 N.J.Super. 516, 368 A.2d 408 (1976). As stated in Thompson v. Kroeger, 380 S.W.2d 339, 343-44 (Mo.1964) (quoting Gatzke v. Terminal Railroad Ass’n of St. Louis, 321 S.W.2d 462, 466 (Mo.1959)):
the exercise of due care requires precautions which a reasonably prudent employer would have taken in given circumstances, even though other employers may not have taken such commensurate precautions. What usually is done may be evidence of what ought to be done, but what ought to be done is fixed by a standard of reasonable prudence, whether it usually is complied with or not.
If plaintiff’s petition establishes defendant’s failure to provide a safe place for plaintiff to work, we must next consider whether injunctive relief would be an appropriate remedy. An injunction may issue “to prevent the doing of any legal wrong whatever, whenever in the opinion of the court an adequate remedy cannot be afforded by an action for damages.” § 526.030 RSMo 1978. Injunctive relief is unavailable unless irreparable harm is otherwise likely to result, see City of Grandview v. Moore, 481 S.W.2d 555, 558 (Mo.App.1972), and plaintiff has no adequate remedy at law. See State ex rel. Taylor v. Anderson, 242 S.W.2d 66, 72 (Mo.1951).
The petition alleges that plaintiff’s continuing exposure to smoke in the workplace is increasingly deleterious to his health and is causing irreparable harm. Assuming the allegations and reasonable inferences therefrom to be true, we think it is fair to characterize deterioration of plaintiff’s health as “irreparable” and as a harm for which money damages cannot adequately compensate. This is particularly true where the harm has not yet resulted in full-blown disease or injury. Money damages, even though inadequate, are the best possible remedy once physical damage is done, but they are certainly inadequate to compensate permanent injury which could have been prevented. Plaintiff should not be required to await the harm’s fruition before he is entitled to seek an inadequate remedy. Moreover, the nature of plaintiff’s unsafe work environment represents a recurrent risk of harm that would necessitate a multiplicity of lawsuits. Finally, the petition states that plaintiff has no adequate remedy at law and alleges facts indicating that prior to this action plaintiff unsuccessfully pursued relief, both through his em-' ployer’s in-house channels and through administrative agencies. Viewing the petition favorably, as we must to determine its sufficiency, we find that injunction would be an appropriate remedy.
Defendant contends the trial court lacks jurisdiction to provide relief, and therefore the petition fails to state a claim upon which relief can be granted, because the subject matter of this case is preempted
