The accidental release of energy is one of the important causes of accidents in the field. The electrical energy, pressure energy, mechanical energy, potential energy and other energies that may be accidentally released must be isolated in a reliable way, otherwise the accidental release of these energies may cause damage in the operation. The accidental release of common error energy is one of the important causes of on-site accidents. The electrical energy, pressure energy, mechanical energy, potential energy and other energies that may be accidentally released must be isolated in a reliable way, otherwise the accidental release of these energies may cause damage in the operation.
The following common mistakes:
If the left picture is not properly protected when filling the pressure cylinder, the inflated cylinder should be put into the explosion-proof barrel as the right picture is.
The image on the left works directly after the quarantine, without verification and confirmation like the image on the right. Just think, what will happen if the quarantine is wrong?
Quarantine set by others is impenetrable without permission. In particular, the isolation of the high-pressure operation shown on the left can be fatal as long as it is electrocuted.
The junction of the high pressure manifold shall be connected with the safety detachable rope as shown on the right. In case the high pressure causes the pipeline to burst open, the connection will cause death when flying.
It is necessary to protect against the sudden release of external tension or internal stress. When cutting the twisted wire rope or the tensioned anchor chain, it is necessary to fix it so that the severed head will not fly randomly, and the work site shall be isolated to prevent it from intrusion and accidents.
The isolation of the energy source should be a certain distance, as shown in the figure on the right, the warning distance of the radioactive source should be 2 meters away.
On the left, the operator is operating the pressure vessel facing the direction of the injection. If the accidental release of energy will cause harm to people, the operator should be positioned to avoid the possible direction of energy release, as shown in the right.
