HOW TO HANDLE ACETYLENE MACHINES
The following cautions are given in connection with a list of acetylene gas machines which have been examined under the rules of the National Board by the consulting engineers: “I Calcium carbide should be kept in watertight metal cans, by itself, outside of any insured building, under lock and key and where it is not exposed to the weather. 2. A regular time should be set for attending to and charging the apparatus during daylight hours only. 3. In charging the generating chambers of water feed machines clean all residuum carefully from the containers and remove it at once from the building. Separate from the mass any nnslaked carbide re maining and return it to the container, adding new carbide as required. Be careful never to fill the container over the specified mark, as it is important to allow for the swelling of the carbide when it comes in contact with water. The proper action and econo my of the machine arc dependent on the arrangement and amount of carbide placed in the generator. Carefully guard against the escape of gas. 4. Whenever recharging with carbide, always replenish the water supply. 5. Never deposit residuum or exhausted material from water feed machines in sewer pipes or near inflammable material, fi. Water tanks and water seals must always be kept filled with clean water. 7. Never install more than the equivalent of the number of half-foot burners for which the machine is rated, ft. Never test the generator or piping for leaks with a flame, and never apply flame to an outlet from which the burner has been removed. 0. Never use a lighted match, lamp, candle, lantern, or any open light near the machine. 10. See that the entire installation is in accordance with the rules of the National Board of Fire Underwriters, a copy of which will be furnished by your insurance agent, and obtain from your contractor a written guarantee that these rules are complied with.”
The Armour Packing company. Kansas City, Mo., is putting in a new intake and repairing the damage to its private system of waterworks done by the recent flood. The old intake which stood in the river a few feet north of the middle pier of the L road bridge at Central avenue was wrecked, and the main pipes through which the Armour company draws a supply of Kaw river water for flushing sewers and yards were buried under the wreckage of the L road bridge.
