Accidents resulting from failure to implement LOTO

Q: why do fire line valves have normally on/off signs? Where else does the toll station need to hang the normally on/off sign? Answer: This actually has the standard requirement, is the fire valve to hang the status mark, in order to prevent misoperation, because the fire water must ensure that there is always, that is to say, in the process of inspection and maintenance, the valve may be temporarily closed, so it needs to remind the relevant personnel. This requirement is actually quite high, mainly for which key fire prevention units. Your unit is only advising. The valve on the gas line is recommended. And then it’s gone. The valve of the gas pipeline is also to remind everyone to pay attention to the status of the switch and ensure that it is closed after use. This does not have mandatory requirement, demand is higher in chemical enterprise, the somebody else still goes up lock. Prevent misoperation, prevent misoperation, prevent misoperation.
Human error is inevitable, so necessary measures should be taken to prevent misoperation. Training should be in place, why LOTO, must tell everyone clearly, rather than in order to the tone, to convince people.
