Ship's daily work, there will be a lot of electrical equipment, high pressure, high temperature, low temperature pipeline maintenance work, involving dangerous energy, in the process of maintenance crew wrong operation or improper operation, lead to accidental release of dangerous energy, light can cause hull or Marine equipment damage, serious can make the crew members were injured, even life threatening. LOTO (lockout-tagout) is a general method of dangerous energy control in the world.
