Stop in for a cup of coffee
Our fork trucks take propane tanks at work... They have three racks for them outside one of our doors... I usually have to change the tank every other day or every day, depending on how much the other shifts use my fork truck...
I learned not to try to push them when you see the low light go on... I've run out before getting near the door and have had to carry the tanks to and from.... the empty ones are lighter than the full ones...
If we run out of gas far away from the 'refill' area, sometimes we can flag another fork lift driver and he will go get one... We have each other's backs...
