15-26-360 Warning and instruction cards – Posting requirements.

   Printed warning and instruction cards provided by the maker shall be posted in a conspicuous position near the acetylene generator so that the operator may consult them conveniently from time to time.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-370 Repairs – Lighting requirements.

   Any necessary repairs to the generator system shall be made during daylight hours by natural light, or by the fixed lights in the generator room. The use of portable lights is strictly prohibited.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-380 Appliances – Maintenance and installation.

   All blowtorches, regulators and other appliances shall be maintained in good condition at all times. No appliances shall be installed in any line which causes or allows the mixture of air or other oxygen carrier with acetylene, except directly at the torch or burner. The use of an expansion tank or tanks in any part of the system is prohibited.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-390 Housing of generators.

   Stationary acetylene gas generators shall be installed in a suitable building which shall be constructed and maintained in accordance with the building provisions of this Code applicable to buildings housing such apparatus.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-400 Piping and relief valves.

   The connections from generators to service pipes shall be made with right and left thread nipples or long thread nipples with locknuts or approved unions. Unions depending on gaskets to make tight are prohibited in pipe sizes under two and one-half inches. Piping shall be arranged so that any moisture will drain to the generator, drip pots or seals. Each generator shall be provided with a gas escape or relief pipe to take care of over- or after-generation. Such gas escape or relief pipes shall be of galvanized iron of the following sizes:

 

Size of Machine (pounds)	Minimum Diameter of Pipe
Up to 25 inclusive	3/4 inch
26 to 100 inclusive	1 1/4 inch
101 to 200 inclusive	1 1/4 inch
Over 200	1 1/2 inch

 

   The relief pipe shall be made as short and as free from bends as practicable. However, if it is more than 50 feet in length or has more than four right-angle bends, a pipe of one size larger than that required by this table shall be used. It shall be substantially installed without traps and in such manner that any condensation will drain back to the generator or its component parts. It shall be carried to a suitable point outside the building and shall terminate in an approved hood or bend at least 12 feet above the ground and remote from windows or other openings into buildings, and shall be so constructed that it cannot be obstructed by rain, snow, ice, insects or birds.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-410 Water supply connections.

   In cases where the generators are supplied with water from city mains or house pipes, and where dangerous pressures might be built up, no direct pipe connection with the generator shall be permitted. In such cases the supply pipe shall terminate some distance above the regularly provided opening for filling, so that water can be observed as it enters the generator.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-420 Drain connections.

   Machines of carbide-feed type shall not be fitted with continuous drain connections leading to sewers, but shall discharge into suitable open receptacles which may have such connections.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-430 Gasometers.

   Gasometers, if used, shall be of the liquid-sealed inverted bell type, of such design that a pressure in excess of 15 pounds cannot be obtained.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)
