AB -  THE health hazards of mechanical refrigeration have begun to receive the attention which their importance warrants. Previously the fire and explosion hazards alone were considered in formulating regulatory measures. Ten deaths and 30 non-fatal cases of injury occurred in Chicago during one year, all of them due to the action of gases used in mechanical refrigerators, without the occurrence of a fire or explosion. The former lack of any clear conception on the part of the general public of even elementary principles of this type of refrigerating apparatus has resulted in a feeling that the cold is produced by electricity, and when the fact is mentioned that toxic gases are employed, it not infrequently causes surprise. People have taken toxic gases into their homes without question because they have felt that the makers of the equipment would not knowingly expose the public to undue danger. Certain manufacturers have deliberately chosen to use methyl chloride as a refrigerant because it was less toxic than other commonly used gases. The 10 deaths were caused by it. Though less toxic than some others, it is both anesthetic in action and less evident to the senses, and therefore stole upon its victims
