Show PLAN TO PREVENT MONOXIDE na POISON doors of garage should be opened before starting engine dangerous indifference to carbon monoxide poisoning in private garages still exists according to the american chemical society which makes public the findings of an investigation conducted by W P yant IV W A jacobs and 1 I B berger of 0 the united states bureau of mines in summing up the dangers arising from running tin an automobile in a closed private garage it can be said according according to the socie tys statement that thero seems to be no limit of time during which the engine may be run in a closed private garage aitra witra alth safety to an all occupant thereof open doors previously the doors should be opened previous to starting the engine even if it Is only intended to take the car ou out t because no matter how bow careful deop people 1 e may bo be a few unheeded minutes taken to look lit at the tires dres or measure the gasoline tank may prove disastrous jt if it Is necessary to run the engine tor for any lengthy period as in making repairs or adjustments the car should by all means be run into the open and even then the direct exhaust should be avoided in order to decrease the possibility of headache and discomfort in spite of the recent extensive investigations on the danger of poisoning by carbon monoxide by inhaling the exhaust gas ol of automobiles much indifference or ignorance still exists concerning the magnitude of the hazard in running engines in small garages the statement says continuing people become indifferent the public has become so accustomed to seeing men working about engines engine a W which I 1 libb are running and to breathing exhaust gas in low concentrations trat ions that they have become more or less indifferent to its dangers few people have regarded or thought that the atmosphere they are brea breathing tIlIng Is not exhaust gas la in a strict sense but an exceedingly dilute mixture of exhaust gas in air made comparatively safe through natural or artificial ventilation exhaust from each engine that tiny may lie running in these places Is many times greater than that in a private garage at home tests show that the carbon monoxide liberated per hour by five fire and seven passenger cars and light trucks Is practically the same especially when idling the cubic feet of cabb carben monoxide liberated per hour by these thes e three classes of automobiles when idling are respectively 35 33 33 and 31 racing the totals are ga 65 and GS CS evidence was revealed of disastrous results should the engine be started and left in operation while the file driver went elsei elsewhere here A concentration of I 1 2 per cent the statement continues may easily be built up tip in a short time and on his return but a couple of minutes would be required to asphyxiate him important concentrations although these higher concentrations are of importance and interest they should not detract from the fact that the matter of first importance Is the rapidity with which the minimum concentration and exposure that will render a man helpless not necessarily at the time unconscious will be formed carbon monoxide Is in many cases especially in these relatively high concentrations ra t tons very insidious in its action and the victim will often suddenly collapse and be enair ly helpless although conscious for a time of 01 bis big condition yet unable to make an escape or give filarial alarm this state will quite rapidly develop into unconsciousness and death especially ally if the engine continues to operate which in all probability will be the case |
