The typical day was spent delivering oxygen to various facilities, visiting clients, and fueling up the truck with liquid oxygen.
It got very, very cold in the winter, but the coolness is enjoyable in the summer. You get the chance to work by yourself for the entire day, which can be very enjoyable, depending on who you are.
There is very little time for slow-down, which can be very stressful when you are behind on reaching facilities. I was expected to do a run in 8 hours, but frequently ended up at 10. I felt that I was expected to go a lot faster than was possible, and this seemed to cause some tension on the management-end.
There is a lot of training, which is good, and the other workers and staff were all extremely supportive and helpful.
On-call does not mesh with your personal life, and is very, very difficult to find a good work-life balance.
This is probably a great job for people who are single or want to make overtime pay, but not great for expecting a smooth and easy workday. I felt a lot of disconnect between what I was expected to do, and what I was actually capable of doing.
The hardest part of the job was getting to locations when the office was closed without any assistance.
The easiest part was the driving (put on the radio, or listen to an audio-book).
The most enjoyable part were the clients, who were frequently very old and very happy to have someone visit and chat with.
This job is for a particular type of person, probably in the trades. The help of clients with oxygen needs is a definite moral boost to being in this position.
