Can I do it alone?

[mainbutter]

My question is, is it safe to handle one by myself all the time? Is having a second handler recommended as it is with the bigger pythons?

Short and sweet, answering what you're asking:

YES.

A bit more explanation with handling larger snakes:

Many 'larger' snakes are not in any way lethal, but if they get pissy and bite you, it can be a hassle to get them off even with help. But it is still 'safe', in that I firmly believe it is impossible for even the largest BCIs to present lethal dangers towards adult humans. The worst you'd get is some torn flesh and have a bit longer time getting the snake off than if you had help.
