One Single Action Only. 465.3.

Regarding "Emergency Switching Off,"  please provide examples of "One single action only." What is "One single action only?" What types of devices are suitable for such use allowing one single action only? 465.3.

  • I had the very same "discussion" many years ago with what I would call and over zealous NICEIC inspector who basically stated that unless its a push button then no other device was for "Emergency switching". Now my discussion was around a lever operated device i.e a firefighter/firemans switch. So what some people have said on this thread, you need to grab the lever then push it up, the spring pin then latches it off.

    Now , when I then showed him what the regs indicated but also the standard description, the definition indicated and emergency stop can be either a button, rod or lever operated device, so with that definition Im still waiting on that NICEIC inspector to draw me or show me an example of a lever operated device that you dont grab then push up or down?

    Too many people focussing on one single action, to me its not the single action of what your hand does its the single operating action of one electrical accessory that latches in the off position and isolates all forms of energy etc from the installation/equipment/machine.

    Also with possible flames licking my backside then me activating that device would be so fast it would be classed as one action!!

  • Camper van catches fire as driver is filling it up at Morrisons petrol station in Weymouth | Daily Mail Online

  • Zoomup, I said its for use by the public!,

    There are other emergency stop devices provided elsewhere for suitabl;y trained and competent staff to operate, and if it is a self service facility the console staff will or should have operated the emergency stop they have rapid access to before a member of the public accesess the one for use by the public.

    My wife, is only 4ft 11, and it would take a very brave man for fear of physical harm to call her anywhere near being short!

    Also my words defined the switch at being no greater than 2M from finished ground/floor level.

  • Zoomup,

    Dont believe everything you read in the papers!!, maybe the camper van was already on fire before it arrived in the filling station..........................

  • Yes I know what you wrote, I read it. In many local filling station kiosks the emergency stop is a mushroom head that can be pushed in one single action. What is the exact wording around the external firefighters' switches that you install?

    The camper van incident is only an example of where an emergency switching off may be required. I do believe that it happened as it has been reported in the national press. I have made no comment on the cause of the fire or when it started. That is not relevant.

  • Zoomup,

    Here you go,:

    " Where the site is unattended, partially unattended, or attendant operated, an emergency switching device has to be provided in the forecourt area, outside of the hazardous areas, visible from all dispensing positions and readily accessible for rapid operation in emergency (i.e. it should not be positioned more than 2 metres above the ground). On large sites a number of suitably located operating means may be required to ensure rapid operation of the emergency switching device.

    Where dispensers incorporate loudspeakers, the supply to the loudspeaker system has to be interrupted by the emergency switching arrangement. 

    The operating means (such as handle or pushbutton) for the device is to be coloured red against a yellow background. Resetting this device alone should not restore the supply. The separate single means of restoring the supply should be manual and located within the building where it is inaccessible to unauthorised persons. 

    A conspicuous, durable and legible notice has to be fitted adjacent to every operating means of the emergency switch device, as prescribed in 9.9.11.".

  • I don't think that a normal careful person would drive a smoking vehicle into a filling station.

  • I personally knew a guy (boyfriend of a friend) who, when flames started coming out from under his bonnet, drove into a nearly filling station so he could use one of their fire extinguishers. They were less than pleased. And he was less than pleased when they demanded he pay to have to extinguisher recharged. Not the sharpest tool in the box.

  • I do not think that anybody would drive a vehicle that was on fire into a filling station.

  • Well all I know is that the guy related the tale to me within the context of being really annoyed that the petrol station was trying to charge him for using their fire extinguisher. Given my general opinion of him, I found his tale (of being on fire and pulling at at filling station to grab a fire extinguisher) credible. But this was 35 years ago.

  • I do not think that anybody would drive a vehicle that was on fire into a filling station.

    Perhaps not, but this hapless Irishman drove one out of a petrol station. Enjoy! https://www.casemine.com/judgement/uk/5a8ff87860d03e7f57ec102c
