Gas Inspection. No change has been made during the year in the statutory requirements or the regulations of the Board with respect to the standards and methods of conducting examinations for candle-power and for impurities. The law requires that the gas shall not give less light than sixteen standard English candles, and contain not more than 20 grains of sulphur or 10 grains of ammonia per hundred cubic feet, and no sulphuretted hydrogen. In accordance with the statutory requirement that the gas shall be tested with a burner best adapted to it, which is at the same time suitable for domestic use, the Board has continued the use of the D, E and F sizes old-style and F size new-style Sugg's London Argand burner, these having been found most suitable for coal gas, low candle-power water gas and mixed gases; while for the higher candle-power water gas and oil gas the Sugg's table-top tip open burner and a small iron tip open burner have been used. There were 916 inspections made during the year, including those of gas supplied by municipal plants. Of this number, 254 were made by the chief inspector. The following tables contain the data obtained by these examinations. For convenience of comparison the companies are divided into four classes, those having five inspections or more during the year, those having less than five, the oil-gas companies and the acetylene gas companies. In the ammonia column, 1.— means that the gas did not contain as much as one grain. When this fact developed, the examination was suspended. |
