If you're fiddling with the monitor and somebody is talking to you infront, and it blows: Best case is you are electricuted and have to go to hospital for burns - worst case would be the tube exploding you having dreadful burns and your mate having a monitor tub in their stomach. Not only that, but the wound would be cauterised from the electricity and heat and burn them inside out if they don't die from the shock and hit.
Not fun.
