Energy isolation for safety
What exactly is energy isolation? Energy refers to the energy contained in process materials or equipment that may cause injury to persons or damage to property. The purpose of energy isolation is to prevent the accidental release of energy (mainly including electric energy, hydraulic energy, gas energy, mechanical energy, chemical energy or heat energy) from harming people and the environment, and to ensure that all kinds of energy are effectively isolated and controlled.
So how do you avoid the accidental release of energy and isolate it? Here are a few commonly used energy isolation methods: remove pipelines and blind plates; Double cut off the valve, open the guide between the valve (double cut with guide); Exit the material, close the valve; Cutting power or capacitor discharge; Radiation isolation, distance isolation; Anchoring, locking, or blocking.
What are the conditions under which energy isolation is used? How to avoid casualties? Physical isolation of external energy sources should be carried out when entering, modifying or repairing equipment, facilities and installations, such as repairing, maintaining or repairing machinery; Such as working in electrical circuits and systems; Use energy isolation when working near other dangerous energies, especially in confined Spaces.
If you want to work safely in restricted space, you should follow the following points: stop the operation and use of dangerous equipment, isolate the pipes and facilities connected with the outside world reliably, and cut off the power supply by removing the insurance fuse or pulling down the power switch and locking it, and hang warning signs; After the dangerous equipment is reliably cut off, open all manholes, hand holes, release valves, vent valves, exhaust valves, material holes and furnace doors on the equipment, according to the type of media in the dangerous equipment with steam, water, hot water, mechanical ventilation or natural ventilation and other ways to clean and replace the medium.
