4. Safety
The question naturally arises with those who have not examined the subject, " Is there any danger to be apprehended from using a Gas Machine?" Experience has clearly demonstrated the fact that a good Gas Machine, properly set up, is equally as safe as tJie use of the ordinary Coal Gas in cities, than which there is no safer method of illuminating buildings. There can be no question as to the safety of using gas delivered through permanent pipes and fixtures. The only possible danger is from handling the Gasolene; if this were done in the building, the escaping vapor might combine with the air and form an explosive gas, the same as if a defective meter or gas-pipe should leak. Therefore, Gasolene should never be handled or stored in the building.
With the IMPERIAL, the Gasolene is always handled in the open air, where any vapor arising harmlessly passes off, and it is stored outside of and at any desired distance from the building. Nothing enters the building except the Gas as manufactured passing through the pipes.
It will be observed that our Machine is Automatic in its operation ; there is no Gasometer; no supply is kept on hand ; the Gas is made just as it is used, whether for one burner or for the whole number for which the machine is rated.
We insert the following letter from the National Board of Fire Underwriters, by which it will be seen that our Machine is endorsed (for safety) by the highest authority :
COMMITTEE ON PATENTS, GAS MACHINES AND CARBURETERS,
OFFICE OF
THE NATIONAL BOARD OF FIRE UNDERWRITERS,
NEW YORK.
Messrs. Denny Bros.
Gentlemen: Denny's Imperial Gas Machine, as submitted by you, has been carefully examined by the inspector appointed for that purpose. Its construction as set forth in the accompanying drawings, and its use in accordance with the rules prescribed for all Air Carbureters, have been approved by the committee of the New York Board of Fire Underwriters having in charge the matter of Gas and Gas Machines, and by virtue of such approval are approved also by this committee under the conditions referred to.
