I need to check AS1496, there will be a copy at work. I tend to agree, plus its a bit awkward, so I've cut a hatch in the floor. If they argue the valve cant be accessed when I've got a load on, I'll argue its the same for a Rangie or commodore loaded up.
The more recent industrial installations I've done ( I work for an LPG distributor) all have had air operated emergency valve actuation. We used to use cables, but maybe thats changed. I know that they rusted up if not used. The LPG tankers I drove 20 years ago all had cable stops, but they were spring loaded and pulling the cable tripped a cam. You had to crawl under the truck to reset them.
I'm simply not up to date. I let the engineers do all that![]()
