LOTO, which stands for Lock Out/Tag Out, is a safety procedure that ensures dangerous machines are properly shut off and cannot be started up again before maintenance or repair work is completed. It's like having a special safety system that prevents accidents by making sure equipment stays turned off when someone is working on it. This is similar to how you might unplug your toaster before cleaning it, but on an industrial scale. Companies take LOTO very seriously because it protects workers from injury and is required by safety regulations.
