【Daily Question No. 275】October 08, 2018: Briefly describe the characteristics and risks of major equipment overhauls. ①The maintenance period is short, the workload is heavy, tasks are concentrated, there is overtime work, and personnel tend to get fatigued ； ②With a small construction site, a large number of workers, and overlapping tasks across various projects, personal accidents are highly likely to occur ； ③Flammable and explosive materials are present, and there is a large amount of welding and gas cutting work during maintenance; improper handling can easily lead to fires, explosions, poisoning, or chemical burns. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

①The maintenance period is short, the workload is heavy, tasks are concentrated, there is overtime work, and personnel tend to get fatigued； ②With a small construction site, a large number of workers, and overlapping tasks across various projects, personal accidents are highly likely to occur ； ③Flammable and explosive materials are present, and there is a large amount of welding and gas cutting work during maintenance; improper handling can easily lead to fires, explosions, poisoning, or chemical burns.
Answer: ① Short maintenance period, large workload, concentrated tasks, need for overtime work, and easy fatigue among personnel； ②With a small construction site, a large number of workers, and overlapping tasks across various projects, personal accidents are highly likely to occur ； ③Flammable and explosive materials are present, and there is a large amount of welding and gas cutting work during maintenance; improper handling can easily lead to fires, explosions, poisoning, or chemical burns.
Risks of major maintenance: There are many temporary operations, as well as numerous hazardous tasks. Such as working in confined spaces of equipment, carrying out hot work, lifting operations, temporary electrical work, etc., and there may also be phenomena such as the natural formation of ferrous sulfide ； Contractor management, blind plate opening and closing operations, etc. – such tasks involve risks, and accidents can occur with the slightest carelessness

A thorough inspection is needed; it must be replaced completely
The maintenance period is short, the workload is heavy, tasks are concentrated, there is overtime work, and personnel tend to get fatigued； With a small construction site, a large number of workers, and overlapping tasks across various projects, personal accidents are highly likely to occur ； There are flammable, explosive, toxic, and harmful substances, which can lead to occupational and non-occupational accidents such as fires, explosions, poisoning, suffocation, noise hazards, and acid or alkali burns.
