Roj yog feem ntau yooj yim mus rau hauv kev sib cuag nrog, qee leej ntawm lawv yog cov roj lom.
Hauv kev ua ntawm kev tsim, kev siv, kev cia khoom thiab kev thauj mus los yog tias koj tsis tuaj yeem tiv thaiv zoo, yuav tsim kev puas tsuaj rau tib neeg lub cev, ua rau muaj kev sib tsoo loj.
Cov nram qab no yog cov npe ntawm cov cwj pwm thiab kev tsim kev puas tsuaj ntawm cov pa roj carbon cua kub, kom ua rau kom muaj kev nyab xeeb ntxiv, kom tsis txhob muaj teeb meem rau tib neeg lub cev thiab kev raug mob lom.
1. Muaj roj ntau, feem ntau cov roj siv tshuaj lom neeg kev lag luam muaj feem ntsib.
Feem ntau hom tshuaj chlorine, ammonia, nitrogen oxides, phosgene, hydrogen fluoride, sulfur dioxide, sulfur trioxide thiab dimethyl sulfate, thiab lwm yam.
Yuav irritate lub qhov muag thiab cov pa nqus cov kab mob ntawm cov roj excitant
2. Cov tshuaj lom neeg asphyxiation - yuav ua rau tsis muaj oxygen rau lub cev.
Asphyxiation asphyxiation thiab muab faib ua cov asphyxiation ntshiab, ntshav cell asphyxiation.
Xws li nitrogen, methane, ethane, ethylene, carbon monoxide, nitrobenzene steam, hydrogen cyanide, hydrogen sulfide, thiab lwm yam.
Hauv qab no yog peb HFP-4 hauv 1 Portable Gas Detector:
