This Industry Standard Update provides an overview of the recently published revised Industry Standard BS 8446: 2020 Installation and maintenance of open-flued, non-domestic gas-fired laundry appliances – Specification, and highlights areas of significant change that the amendments have introduced. The appliance may have multiple burners and it may not be practical to isolate each burner in an emergency or for servicing.

It should be in a secure, well-lit, and convenient area. Additionally, the placement of your equipment isolation valve can be determined by where you need to use it and how accessible it is for technicians. Isolation at the meter is not always practical and vital time may be lost in gaining access to the meter. An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes. [1] They can also be used to provide flow logic (selecting one flow path versus another), and to connect external equipment to a system. [2] A valve is classified as an isolation valve because of its intended function in a system, not because of the type of the valve itself. Therefore, many different types of valves can be classified as isolation valves. Laundry establishments are regarded as a workplace. Not all domestic-type detectors and alarms conforming to BS EN 50291-1 are suitable for these applications unless the manufacturer specifically warrants this and confirms that it sounds at the workplace occupational exposure limits. Where gas appliances are in use there a should be a local or appliance gas shut off or isolating valve. This is typically a lever ball valve with a handle (often yellow). When the handle is in-line with the pipe, the valve is open and gas will flow to your appliance. To shut off the gas to the appliance, turn the handle 90 degrees so it’s perpendicular to the pipe. Locating all of your appliance shut off valves is important in case you need to use them in a hurry. If you don’t find a valve, you may not have any installed. A good gas safe plumber will help confirm that and will install suitable valves to give you that all-important control over your gas flow. Getting help with your gas and heating

When you next see your trusted local gas plumber for a boiler service or gas heating repair, they’ll be more than happy to take you through all the items on your list. A happy safe customer that knows all about their heating system is a great customer for any good gas heating engineer. Information Notice No. 85-71: CONTAINMENT INTEGRATED LEAK RATE TESTS". United States Nuclear Regulatory Commission . Retrieved 25 February 2012. Clause 8.2.2 states that a pressure test point shall be installed as near as practicable to the exit downstream of the manual isolation valve to facilitate tightness testing.

Everyone has to be aware of how gas appliances operate and necessary safety practices if they are present in the home. In case there are any appliance problems, it is also essential for everyone to spend some time learning about emergency methods.However, to ensure that all components are appropriate and safe, you should never directly touch a gas isolation valve. Instead, always have expert technicians do the task. The purpose of this Information Sheet is to provide, for industrial and commercial installations, a consistent approach to: As previously stated, this Industry Standard Update is only a brief overview of the information contained in the amended standard. Registered businesses should be aware that they have a responsibility to ensure that they are fully apprised of all of the requirements of the whole published standard and its practical application.
