Strict adherence to ja fe ty regulations, with repeated re- ,,Inders of the rules, will keep acci- ^,,Is 'at a minimum: Frequently in established operating proce^urcs. sn attitude of carelessncSS may lead to disastrous results. One such case occurred in the use of hvdrogen gas. A set of apparatus was arranged to determine the amount of g as consumed in the hydrogenation of an oil sample The unit consisted of meters with drying towers ai\d irapj. After the eat run the equip ment had to be dismantled and cleaned (or another nm. This experimental unit had been used every day for several years without mishap. One day, however, after the apparatus had been par tially dismantled for cleaning, a chemist started to remove hardened oil from a delivery tube leading to one of the traps--a deposit which usually is removed with a small brush or swab. In a hurry to get to other work, he used a Bunsen burner to melt the hardened oil. The hydrogen had been ihut off at least 20 minutes and the apparatus dismantled for 15 minutes. Aloud blast accompanied by a show er of glass occurred. Fortunately, the chemist was unhurt. Apparently the hydrogen in the trap had dissipated to an extent where an explosive mix ture was formed. The damage was done by less than a liter of hydrogen gas in an explosive mixture. A variety of gases are used in the W p and electronic tubij industry-- air, both compressed \|n d liquid; carbon dioxide in solid form (dry tee); hydrogen; nitrogen; helium, and the rare gases. Some of the gases are handled in cylinders at pressures up to 2000 lbs. per sq in. Any device containing materials under pressure should be handled with care, Protective caps should be supplied with all cylinders in transit to prevent the valves breaking if struck. Cylinders, when in use, shrould be firmly supported to pre vent falling. Air presents hazards both under high pressure form and in the liquid state. The use of high-pressure a ir" for spraying, drying and other pur poses is widespread. High-pressure air can cause particles of dust and gritty material to By with force suf ficient to cause injury to the eyes, ears, etc. A high-pressure air stream directed against the body can rupture internal organs. The use of high-pressure air should be restricted to those areas where these hazards can he avoided, and in all cases the extra protection of gog gles for operators is a wise precau tion. Liquid Air Liquid air is used in specialized manufacturing operations and pre sents hazards of explosion, fire and personal injury. It should be handled in special containers designed to al low for the escape of vaporizing gas and to keep atmospheric moisture from condensing in the neck of the container, Condensing moisture will rapidly form a plug of ice which would prevent the escape of expand ing gas. Internal pressure thus builds up to explosive force. .Liquid air should be kept away from combustible materials such as oil, finely divided metals, charcoal, etc., due to its oxidizing properties. Another hazard of liquid air is the possibility of bodily injuries due to faulty handling. The hands should not be covered with gloves or rags when liquid aid is poured. It will evaporate readily if splashed on the bare skin, but is trapped on gloves or rags, The evaporation rate is low ered appreciably and severe "burns" or frost-bite may result. Carbon Dioxide Carbon dioxide, in the solid state, commonly known as .dry ice, is used either alone or mixed with alcohol to obtain low temperatures on special equipment. In this form the greatest hazard is that of severe "burn" o r . frost bite by bodily contact with the solid. Minor hazards are those of ex plosion and suffocation. Restriction, of dry ice in a closed container can result in an explosion if sufficient carbon dioxide is present in a weak-walled container, such as a glass bottle. If sufficient carbon diox ide gas is generated from dry ice in a small confined room the hazard of suffocation may result Precautions are fairly simple. Dry ice should not be allowed to touch any part of the body. It should not be used to cool drinks. A small piece will cause painful frost-bite in the stomach and may cause ulcer forma tion. Dry ice should never he placed in tightly stoppered containers such as bottles or jars. Rapid vaporization of solid COj may cause a pressure to build up to cause an explosion. A room with a high percentage of carbon dioxide in the atmosphere furnishes evidence of its presence by the symptoms of quickened breath ing, dizziness, ringing in the ears, and other unusual sensations. First aid treatment in the case of burns is the same as for heat bums, followed by the services of a phy sician. Swallowing dry ice is a se rious matter and a physician should be called immediately. In the case of accidental suffocation, the body should be removed from the area dermatitis commonly known as "nick gen therapy is of little use in cy and artificial respiration applied at el itch."

First aid consists of remov-. ing the victim to fresh air and apply ing artificial respiration. The services of a physician are necessary. The use of hydrogen gas finds many applications in live lamp and tube industry. Heat-treating ovens, are classified by the American Stand ards Association as a severe hazard. Chromium compounds, such as chromic acid or chromates, are used in electroplating and in glassware cleaning operations. Due to the low cathodic efficiency of the chromium plating baths a fine mist of hydrogen gas laden with chromic acid is formed at the operating positions by the bursting of many fine hydrogen bub bles on the surface of the plating so cyanides should be such that in c.i -'of accidental breakage the acid cajj; l not come into contact with cyanide^'.'

Hazards of explosion and fire are ever present, and even small amounts of hydrogen gas can cause a serious accident. Following safety regula tions in the use of this material will prevent a majority of accidents. Other gases commonly used are: acetylene, oxygen, nitrogen, helium, argon, neon and illuminating gases. The maximum allowable concert- (ration of chromium as chromate or dichromate dust or as chromic acid mist, has been set at 1 milligram of chromic acid in 10 cubic meters of air for exposures not exceeding a to tal of eight hours daily.

Accidents may occur either in washing the towers or drying tubes containing litis material. Vio lent sputtering of the material will occur unless the operation is per formed very slowly and carefully. In halation of the dust in loading a fresh tube produces a stinging or biting sen- saiion in the throat and settling of die dust on the skin causes itching. This material should be handled only when protective goggles, respi rator, gloves and aprons are worn.

Mixtures of ethyl and methyl alcohol arc the most common, and though hazard of fire in the use of these flammable liquids s ever present, the hazard to health is generally overlooked. Even ethyl alcohol in g e s te d by the human body has resulted in death. It is readily de composed by the body into carbon di oxide and water. On the other hand, one of the products of the oxidation of methyl alcohol is an extremely poisonous substance--formic acid. Diagnosis of methanol poisoning is featured by the characteristic damage to the optic nerve resulting in severe blurring.of vision or total blindness. Two hundred parts per million is considered the limit for a safe atmos phere. An adequate -exhaust system is the best precautionary method. Substitution of denatured grain al cohol for mixtures containing high percentages of methanol is also rec ommended, Where methyl alcohol poisoning is suspected, the victim should be treated by a physician. The volume of benzol used in the lamp and tube industry is not great, and the greatest hazard of this flam mable liquid is that of injury to health. Benzol produces bone mar row changes. In acute poisoning the central nervous. system is affected, whereas in chronic cases the bloodforming system is damaged. In a number of the acute cases reported, death has resulted.

It is a highly volatile liquid, giving of! even at comparatively low temperatures vapors which form flammable and explosive mixtures with air or oxygen. Spontaneously explosive peroxides sometimes form on long standing or exposure of bot tles to sunlight. The yapors are heav ier than air and may travel a consid erable distance to a source of igni tion and flash back. It is classed as more hazardous than gasoline. When inhaled, ether usually pro duces an initial symptom similar to alcoholism and called the "ether jag." Inhalation of a concentration of 35,000 parts per million causes un consciousness in about a half an hour. Continued inhalation of such concentrations can result in death due to failure of respiration. Susceptibil ity to pneumonia is increased by ex posure. Chronic exposure affects chiefly the digestive and nutritive or gans. Operators who have been ex posed to ether inhalation may be rendered "dead drunk" by a single drink of whisky. Precautions against fire and ex plosion include explosion-proof light ing. electrically grounded equipment. Storage of ether in rooms where tem peratures are normal will prevent internal pressures - from rising and rupturing the containers with explos ive violence.

Lubricating or protective skin creams are being used Kith success. Ether b used to a rather limited extent in special rapid drying appli cations. It is a highly volatile liquid, giving off even at comparatively low temperatures vapors which form flammable and explosive mixtures *ilh air or oxygen. Spontaneously explosive peroxides sometimes form on long standing or exposure of bot tles to sunlight. The vapors ore heav ier than air and may travel a consid erable distance to a source of igni tion arid Sash back. It is classed as more hazardous than gasoline. When inhaled, ether usually pro duces an initial symptom similar to alcoholism and called the "ether jag." inhalation of a concentration of 35,000 parts per million causes untonsciousness in about a half an hour. Continued inhalation of such concentrations can result in death due to failure of respiration. Susceptibil ity to pneumonia ia increased by ex posure. Chronic exposure affects chiefly the digestive and nutritive orcans. Operators who have been exposed to ether inhalation may be rendered "dead drunk" by a single drink ol whisky. Precautions against fire and ex plosion include explosion-proof light ing, electrically grounded equipment. Storage of ether in rooms'xbere tem peratures are normal will prevent internal pressures from rising and rupturing the containers with explos ive violence. Persons with severe colds, or bron chitis should avoid exposure to ether '*por. Adequate ventilation, prefer ably at the point of vapor origin, is ho important.
