TO WHOM IT MAY CONCERN
Re: the health and safety of gasoline dispensaries’/ such as convenient stores/ gasoline stations, etc.
Critical to the health and safety of the workers and owners involved in this business is the problem of “SPILL BUCKETS”/ THAT RESULT IN CONTAINMENT OF THE OVERFLOW, that comes when the nozzle delivering the fuel from the tanker; DOES NOT shut off in time.
The result of that is a gallon or more of gasoline that ends up in the spill bucket (the area around the fuel piping to contain spills)/ and must be cleaned out by the business fuel was delivered too. That results in wasted fuel, hazardous locations, etc. Some fill pipes are not enclosed by concrete, as is consistent with a spill bucket/ thereby the excess fuel simply sinks into the ground.
The critical change that is necessary to this work is simply: CHANGE THE FUEL NOZZLE, ON THE TANKER! The problem is: that the nozzle cannot identify the pipe filling up soon enough to properly shut off. The SOLUTION IS: to change the “down pipe”, from the nozzle, that extends into the tank piping. IF IT WAS LONGER BY AT LEAST ONE FOOT, then this entire problem would simply disappear. That can be done with TELESCOPING PIPING “TWO STAGES INSTEAD OF ONE”. Which leaves the nozzle still fitting into the tanker truck enclosure. Another fix for this problem is: to slip on or attach a large rubber washer disk; to the down pipe. Thereby lightly sealing the top of the fill pipe, which will aid the nozzle in identifying the pipe is full and the nozzle needs to shut off. Nozzles react by increasing pressure. You can make the disk that sits on top of the fuel fill tube out of aluminum to create a ground instead of rubber. Simply enclosing the 4 inch pipe hole to a more appropriate size, so that the 1 and a half or 2 inch fill nozzle fits more correctly; so as to operate the nozzle mechanism and shut off properly is also an option. A simple insert into every fuel fill pipe solves this problem; but you need one for every fill pipe.
This problem to health purposes is identified by an owner un-identified that has developed allergies to gasoline first/ and is now experiencing change in vision associated with the eyeball becoming liquid instead of a gel inside: blindness is a possibility. The reality: TOO MUCH TIME directly above the spill bucket, as they have been cleaning it out with a rag and bucket. That leaves the human being over the spill bucket breathing the fumes, and the vapors invading the eyes: with numerous other potential biological problems.
Due to the flammable realities of removing gasoline; no machines have yet been used for the removal of this spilled fuel. Breathing masks are not likely to be used/ and these would need to cover the eyes as well. Spill buckets are designed to include a drain which can then be opened to return the fuel into the tank/ HOWEVER the spill buckets themselves become filthy, and that is not a realistic option. As well as any form of drain into the fuel tank below; can and does cause rain water to enter the tank as well/ causing more problems.
NONE OF THAT IS NECESSARY, IF THE TANKER NOZZLE SIMPLY SHUTS OFF WHEN REQUIRED. That is as simple as a tiny inexpensive change.
