Description

Technical Field

[0001] The invention belongs to the technical field of confined space operation safety, and in particular relates to a confined space operation emergency rescue device. Background Art

[0002] Confined space refers to the interior of various equipment in industrial production and various closed and semi-enclosed facilities and places such as tunnels, sewers, ditches, pits, wells, pools, culverts, valve rooms, and sewage treatment facilities. There are many risk factors in this scenario, mainly including: poisoning, suffocation, fire, explosion, electric shock, drowning, collapse, object impact, high temperature and humidity, etc. Since confined spaces are usually relatively closed and poorly ventilated, oxygen consumption or gas substitution often leads to a decrease in oxygen content. In addition, due to production, operations, chemical reactions, microbial effects, etc., there may be toxic substances such as hydrogen sulfide, carbon monoxide, and phosphine in confined spaces, which are easy to accumulate in limited and closed spaces with poor ventilation, causing poisoning and suffocation of trapped persons and rescuers, and easily causing casualties. Confined space rescue can be divided into three main types or levels, namely self-rescue, non-entry rescue, and entry rescue. The internal space of a confined space is small, and it is difficult for rescuers to enter, evacuate, and rescue trapped persons. Therefore, when conducting rescue operations, it is necessary to fully consider space limitations and safety issues, and ensure that rescuers have professional knowledge and skills, and are equipped with appropriate rescue equipment and tools to maximize the success of the rescue operation and the safety of personnel. It can be seen that accident rescue in confined spaces is difficult and dangerous, so it is necessary to carry out research on accident rescue in confined spaces. Summary of the invention
