There are several things to pay attention to before using loto locks to lock the door.

1. First of all, we must check whether the loto lock itself is intact, whether it can be used satisfactorily, whether the various contents written on the signboard are detailed and accurate, and the lock can be executed only if there is no problem after the query.

2. To hang a tag on the lock, the card that must be hung on the loto lock, and then turn off the power of the stun gun switch of the device.

3. After locking the list, all staff in the working area should be notified according to different channels. This device has been locked, and no one can remove the locking process of the device at will without permission and the presence of relevant personnel. Only the person who locked it or the authorized person is qualified to remove the locking process of the device.

4. During construction, installation, overhaul, infrastructure, maintenance, inspection, and operation, if the stored materials are dangerous goods, or the energy source is suddenly released, which may cause damage, all potential dangerous energy sources should be protected during such operations and the signs should be locked.

5. Before opening the lock sign, all operators, affected equipment, and system software affected by this protection must be notified, and the relevant operations must be stopped.

6. The staff who perform the actual operation lockout list should carefully remove and separate all residual energy, and carefully check the relevant equipment and systems to ensure that the equipment, equipment and paths are in a zero energy state before starting maintenance or repair.

7. After the actual maintenance or repair operation, before the equipment and system software release the maintenance operation, the relevant staff and number should be fully checked and verified first. The relevant staff who were previously on site must have been evacuated from the site to leave the corresponding equipment and systems.
