¶1Plaintiff recovered damages in the sum of $3000 for personal injuries claimed to have been caused by defendant’s negligence whereby it is alleged a fire was set in .a shed occupied by plaintiff. The facts as relied upon were that plaintiff’s husband was a tenant of defendant, occupying a wing of her house at the corner of Sixteenth and Can-field streets in Detroit. Behind the house was a low shed divided into three parts by internal partitions from five to six feet high, of which defendant occupied the middle one, and plaintiff’s husband the adjoining one at the north end. In the middle partition was a water-closet used by defendant and her tenants jointly. In this middle part, on the side furthest from Mr. Cook’s, was an ash-barrel, which Mr. Cook described as a stout, iron-bound cask, such as is used for liquids. Plaintiff claims that the fire was caused by ashes in this barrel. She and her husband, as they testify, -were awakened by the light of the fire burning through the top of this middle part, and as soon as they could the}' went into their own part and she undertook to get out their horse, that was lying down so that she could not easily loose the halter. While trying to do this the fire swept over the partition and burned her very severely, so as to nearly or quite disable her from doing her accustomed work.
¶2Several questions arose on the trial, on which rulings were made which were complained of. We shall only notice those which seem to be of most importance.
¶3*439Among other witnesses sworn was Mr. Baxter, the city-fire marshal, who was allowed to testify not only to what he saw on the ground the next day, but also what opinion he had of the origin of the fire, and what he heard from various, persons who were there.
¶4This was improperly allowed. That officer’s duties are important and he may properly enough make such inquiries as he deems necessary to aid his own judgment. But when the rights and liabilities of private persons are in question, he cannot affect them by his opinions or conclusions, however sagacious he may be. "When he testifies, he is governed by the same rules as other witnesses, and cannot give either hearsay or opinions. What is said or done after a fire cannot be regarded as part of the res gestae at the fire, and the sayings and doings of third parties could not usually be receivable. And as for the origin and cause of a fire, it cannot in such a case as this be any more difficult for the jury than for a witness to make deductions from the facts shown. There is no room for expert testimony, and his opinions were not receivable. This testimony was referred to in the charge of the judge, and is qiiite likely to have had much weight. There were several facts shown which 'were fairly claimed to have indicated the possibility, if not probability, of a different cause, and the jury should have been left to form their own conclusions, unaffected by any one’s opinion. A similar question was decided by this Court in Fowler v. Gilbert 38 Mich. 296.
¶5The court also charged the jury that a violation of the city ordinance requiring ashes to be kept in' metallic or other incombustible vessels was negligence in law, for which defendant would be liable, and this was emphasized by the further statement that if this was not done she was not responsible in this case.
¶6This doctrine is not maintainable as stated. The primary’ object of municipal ordinances is public and not private, and their violation is redressed by the legal penalties. Taylor v. Lake Shore & M. S. R. R. Co. 45 Mich. 74. City ordinances are necessarily made general, and impose duties which in a *440given case may be of no special importance. It is quite possible that under certain circumstances, and in various surroundings, it is in no way dangerous to put ashes in wooden barrels, and it can never be dangerous to put cold ashes in them. It is certain that asli-barrels are and always have been more or less used. 'Whether the use of them is culpably negligent in a given case must usually be a question of fact to be determined by the jury on the facts, and not by the court.
¶7The principal question in the case was upon the liability of defendant if the fire took from negligence for which she may have been chargeable for the damages on which recovery was had in this case.
¶8The plaintiff showed by her testimony that she and her husband saw the ash-barrel daily and knew all about its position. It also appears by the showing of both that the shed, which was entirely open within from end to end, above the partitions, was burning so brightly as to wake them up, and continued burning when they entered to loose the horse and Iget out the buggy. The danger was before their eyes, and what ¡happened by the sweeping down of the flames was as likely to I happen as not. It is not very important by what name the ¡action of plaintiff should be called. It was such a risk ¡ as she chose to take, to save her husband’s property. But it was a plain and palpable risk nevertheless, and the injury 'would not have occurred unless for her voluntary act in 1 assuming the exposure.
¶9There is some conflict in the cases concerning what^am-ages have been held not too remote for recovery. But it would be going beyond all reason to hold a person liable for bodily injuries suffered by another in voluntarily and deliberately entering a burning wooden shed not divided into detached parts, and reached by the flames while at work within it. The loss of presence of mind under such circumstances is one of the commonest and most likely incidents of incurring such an exposure. The act in which she was engaged may have been such as she may have thought proper and laudable, and worth some risk, but defendant’s responsi*441bility cannot be created or increased by such independent and voluntary conduct of plaintiff in putting berself in harm’s way. /
¶10We think that no recovery should have been had on the facts as shown by plaintiff herself, and that the case should not have gone to the jury.
¶11The judgment must be reversed with costs and a new trial granted.
