¶1This is an action for personal injury in which plaintiff obtained judgment in the circuit court in the sum of $2,000 for the loss of an eye caused by poison.
¶2
¶3Defendant contends that it Was not guilty of negligence and is not responsible for the accident. Plaintiff’s contention is not that defendant knew the fact established by experts that decayed matter of the kind described would produce poisonous bacteria, but that if defendant had been ordinarily prudent and careful it would have become informed of that scientific fact, and would have warned plaintiff of the danger and provided him with glasses to protect his eyes.
¶4The case concedes that plaintiff did not know of the danger attendant upon such work.

¶7“Occupations, however important, which can not be conducted without necessary danger to life, body or limb, should not be prosecuted at all without all reasonable pre*45cautions against such dangers afforded by science. The necessary danger attending them should operate as a prohibition to their pursuit without such safeguárds. Indeed, we think it may be laid down as a legal principle, that in all occupations which are attended with great and unusual danger there must be used all appliances readily attainable known to science for the prevention of accidents, and that the neglect to provide such readily attainable appliances will be regarded as proof of culpable negligence. If an occupation attended with danger can be prosecuted by proper precautions without fatal results, such precautions must be taken by the promoters of the pursuit or employers of laborers thereon. Liability for injuries following a disregard of such precautions will otherwise be incurred, and this fact should not be lost sight of. So, too, if persons engaged in dangerous occupations are not informed of the accompanying dangers by the promoters thereof, or by the employers of, laborers thereon, and such laborers remain in ignorance of the dangers and suffer in consequence, the employers will also be chargeable for the injuries sustained. Both of these positions should be borne constantly in mind by those who engage laborers or agents in dangerous occupations, and by the laborers themselves as reminders of the duty owing to them. These two conditions of liability of parties employing laborers in hazardous occupations are of the highest importance and should be in all cases strictly enforced.” Mather v. Rillston, 156 U. S. 391.
¶8In Smith v. Car Works, supra, the servant with another was directed to carry molten iron from one room to another along an icy path on the outside of the building. In doing so, his companion slipped and fell on the ice, precipitating the iron on the ice causing an explosion and scattering the melted iron on the servant from the effect of which he died. The court held that while the servant must have had the common knowledge that ice was slippery and dangerous to *46walk upon, yet as lie did not know of the fact that an explosion would follow the contact of melted metal with water or ice, it was the master’s duty to have warned him and in failing to do so was guilty of negligence. In Smith v. Iron Company, supra, the service was mining. Ordinary blasting powder had been used, when the master concluded to introduce a more dangerous explosive and one requiring further knowledge and different handling from that of ordinary blasting powder, known as giant powder. The court said, that, before allowing the new compound to be used it was the duty of the master to have ascertained and made known to the servant its danger and the mode of using it. That it was negligence to furnish such an article without the requisite information to those who were to use it. And that whether the master was aware of its dangerous quality, or furnished it without having obtained such information it ivas equally liable.
¶9The case found in 156 U. S., supra, approving opinion of Severeus, L, of the federal circuit, 44 Fed. Rep. 748, was where a servant was injured by the explosion of dynamite and exploders, or fulminating caps, caused by exposure to too much heat, or to excessive jarring of the building by the machinery in use.
¶10In the case of Fox v. Peninsular Works, 84 Mich. 676, a laborer sued a manufacturer of Paris green for injuries to his health caused by inhaling vapors arising in the process of manufacture, which is done by placing a mass of poisonous ingredients in a large vat and bringing it to a high degree of heat. The defendant was held liable for failing to inform plaintiff of the danger of inhaling such vapors. On this point the court said:
¶11“A man might know that Paris green was a poison if taken internally, but not know that it would cause pustulation by handling, or be absorbed into the system and cause poisonous effects from contact with the outer surface of *47the body. It was the duty of the defendant not only to inform the plaintiff that it was a poison, but of the effect it might produce to one working in its manufacture without taking’ due precaution, and the precaution necessary to be taken should have been pointed out if known to defendant and all proper and reasonable appliances and facilities provided to guard against the dangers to be encountered in the employment. Then the person taking the employment would assume the risk of it.”
¶12"We think, therefore, that whether judged by the accepted rule making it the master’s duty to provide a reasonably safe place for his servant to work, and reasonably safe appliances to guard him, as well as may be, from the dangers of his employment; or whether judged by the current of authority applying the rule to a variety of uncommon cases, it may be safely said that it is the duty of the employer to become informed of those matters of scientific knowledge possessed by men of general education and information relative to the danger and hazard of. the business in which he is engaged. That he should give information of the danger to his uninformed employees, and should provide them with reasonably safe appliances for protection. And it is negligence to fail to comply with such duty.

¶14In Mfg. Co. v. McCormick, 118 Pa. St. 519, a servant was engaged in painting the inside of a tank twelve feet deep. He had a lamp and a can of paint. An explosion occurred which injured him. It is supposed the explosion was occasioned by the quantity of benzine in the paint evaporating and filling the tank with explosive gas. The court said that, “the accident happening under such circumstances was outside the range of ordinary experience, and one, therefore, against which the measure of care due from the employer could not protect the servant,” unless the employer is to be considered an insurer. See also as bearing on the question O’Malley v. Railway, 113 Mo. 319. In the recent case of Hoepper v. Southern Hotel, 142 Mo. 378, it is said that a neglect to anticipate and guard against that which no reasonable man would expect to occur would not be negligence upon which an action could be based.
¶15We are of the opinion that an application of this principle of law to the case before us exculpates defendant and causes a reversal of the judgment. The testimony of experts shows that the injury to plaintiff’s eye was caused by bacteria, a poisonous live object germinated in the decayed matter which had formed on the rail along which the carcasses of animals were propelled, as already described; that one or more of these lodged in plaintiff’s eye while he was at work cleaning the rail. It was shown that this substance on the rail when brushed off was a yellowish dust, which fell and settled about, among other places, over plaintiff’s clothing and on his face and hands and also over the fifteen or sixteen other persons engaged in the same service. This dust necessarily floated in and through the room and building. It was doubtless inhaled through the mouth or *49nose of, not only those immediately engaged in the work, but many of the large number of defendant’s other employees. It only harmed plaintiff. It is not shown that in all the cleaning of such matter from similar places, or from any place, that bacteria had found lodgment and worked injury to any one. The same testimony relied upon to make out plaintiff’s case shows that these live objects or germs are so small and so light that large numbers of them may be in a single drop of liquid; that they can take hold of and work havoc in a membraneous substance like the human eye, or nose, or mouth. So that when we consider that such substance as was on this rail exists in different forms in, perhaps, every part of the earth, that it is being disturbed by persons and animals and the winds, we readily see that the atmosphere in the vicinity must be filled with them and that they are getting into the eye or the nose of all who may be in their reach. And yet men do not provide themselves with sponges for the nose or mouth and goggles for the eyes that these objects may be kept out. When they do find lodgment and worJc injury to a human being, it is by the merest chance; otherwise the race would be in danger of destruction. It must be true that the human organization is such that it neutralizes the harmful results from these microscopic animals, except in rare instances. Their harmful effect is simply one of the remote chances which we take for existence. It is now stated by scientists that tuberculosis is caused by live germs and that they are discoverable in the sputa of the one afflicted. This is expectorated by such persons and when it has become dry and powdered can get into the atmosphere and thence be taken into the lungs of other human beings. It is said by many of the learned that the disease may be contracted in tin's way. Yet would a master who had in his employ a person so afflicted, be required to warn his other servants of the danger, a danger existing, as experts state, yet so remote as *50to cause the fact to be questioned? Some particles of the substance, in defendant’s packing bouse, from which these living organisms spring must be found in crevices in different parts of any packing house, especially in the floor. When the floor is swept the germs must rise in the atmosphere and find lodgment in the nose or eye of employees; and yet it would' scarcely be contended that for a harmful result which might occur, traceable by experts to bacteria, the master would be liable. Uninformed and uneducated men are employed to work in and near marshes and stagnant water, in sewers and other places where disease breeding microscopic animals are said to thrive, yet it is not believed that the master furnishes protection against inhaling these.
¶16I do not question but that a master may put his servant to work where he would come in contact with disease (a disease communicated by germs) for the doing of which he would be liable for the resulting injury, but it would be in such instances where it is- well known that the disease would probably be communicated, and not where the injurious result is so remote as to scarcely engage one’s attention. If a master should knowingly engage his child servant in a place where he would come in contact with contageous diseases common to children, he would be liable for the injurious consequences, but would be be liable for putting his man servant to work in the same place when the disease only attacked adults in the rarest instances, that happening to be one of them?
¶17“A reasonable man does not consult his imagination, but can be guided only by a reasonable estimate of probabilities. The reasonable man, then, to whose ideal behavior we are to look as the standard of duty, will neither neglect what his reason and experience will enable him to forecast as probable, nor conduct on a basis of bare chances, a business whose success is dependent upon his accuracy in forecasting the future. He will order his precaution by *51the measure of what appears likely in the usual course of things.” Ray’s Negligence of Imposed Duties, 133. Webb’s Pollock on Torts, 45, says that, “a reasonable man can be guided only by a reasonable estimate of probabilities. If men went about to guard themselves against every risk to themselves or others which might by ingenious conjecture be conceived as possible, bumau affairs could not be carried on at all.”
¶18The foregoing from the texts of the authors mentioned, was quoted, adopted and applied by Burgess, J., in American Brewing Co. v. Talbot, 141 Mo. 674, a case in which it was sought to fix the charge of negligence on the defendant in not anticipating the sinking or settling of a warehouse caused by an unusual rise in the Mississippi river. It is held in that case that, “when an injury can not reasonably be anticipated and would not bave happened except under exceptionable circumstances, it is not negligence to fail to take precautionary, measures to prevent it, although if taken the injury would not have resulted.”
¶19We are, therefore, of the opinion that plaintiff had no case and reverse the judgment.
