Cool. I wouldn't worry too much about what the resellers think. They never seem to include the right safety information. My glut came in a squeezy bottle that looked exactly like hand wash, with the green (safe) push down nozzle. It had colourful pictures of plants allover it. You can only imagine how dangerous this is to children that cannot read. There was no child safety lock. Even if they could read "easy carbon" it would probably sound safe and natural to them. My grandmother is also blind and I used to drink, so you can imagine how dangerous these bottles soon become. All plastic containers are not equal. You need one that will not let any vapour escape. Some plastics are rather unsuitable, so I think their advice was also wrong. They were probably not qualified to make these assertions. I would glue the bottle in place so that it cannot tip over or use a secondary containment, and use extra screws in the wall mounting. Use blue butyl gloves and you'll protect your hands. A sign goes a long way in case you have random or uninvited guests that could touch it; police and burglars will raid houses by accident and not know what it is etc. A chain and lock over the cabinet handles is what I do.
