Accident causes and remedial measures in pipeline

Before construction, it is necessary to check whether there is any leakage in the pipeline. If there is any leakage, it should be carried out after taking leak elimination measures; The operator shall wear necessary protective equipment, and the site shall be well ventilated with a ventilation rate of more than 12 times/h. Polyurethane foam plastic shall be used on the site, and its oxygen index shall be more than 26. After the work is completed, the residual toxic substances on the site shall be eliminated.
2. The causes of burns, frostbite, and burning are generally: acid and alkali leakage during insulation of pipelines and underground pipelines; No insulation measures were taken for the high-temperature steam pipeline and high-temperature furnace wall, and no anti freezing measures were taken for the low-temperature pipeline. The measures that need to be taken are: before construction, the pipeline should be checked for acid and alkali leaks, and construction can only be carried out after taking leak control measures; After taking insulation measures, insulation work and anti freezing measures can be carried out, and various valves must not be tampered with.
3. Puncture injury, its causes are generally: when sewing slag cotton, two people work opposite each other, steel needles puncture the other person, and when working on the back, without wearing a safety helmet and goggles, iron wire punctures the head, eyes, and exposed parts of the body that come into contact with slag cotton and glass wool. The measures to be taken are: when sewing slag cotton, the two people on the opposite side should stand in a staggered position and wear safety helmets and goggles to ensure necessary protective measures are in place.
