I have a job interview coming up for an EMT-Basic position. A friend of mine told me that part of the testing will involve using a stair chair. I have been a Basic for over a year and in all that time volunteering and taking classes I have never seen or trained with one. Physically I'm strong enough to do whatever the test requires but I'm unsure about the procedure involved with using a stair chair. If anyone knows the proper technique for using these please let me know.
