Specifies the uniform minimum requirements for the design, construction and safe operation of TypeB appliances that are intended for use with town gas, natural gas, simulated natural gas, liquefied petroleum gas and tempered liquefied petroleum gas or any combination of these gases either together or with other fuels.
The objective of this Standard is to provide uniform minimum requirements for the safe operation of gas-fired industrial appliances and other large appliances used for commercial applications which are not covered by any other Standard.
This Standard does not cover all the requirements for the safety of the process carried out in the appliance. Other statutory and regulatory requirements may be applicable to the appliances or installations, or both, that fall within the scope of this Standard. It is the installer/original equipment manufacturer’s responsibility to ensure that appliances and installations conform with these requirements.
This Standard should not be regarded as a design specification or as an instruction manual—it has been prepared with consideration for gas rules and regulations now in force.
In its preparation, primary consideration has been given to—
(a) the prevention of injury to persons; and
(b) the prevention of fire and explosion hazards associated with fuel use and processes, particularly where they could lead to a risk of injury of persons.
