Ubufakazi bokuqhuma kwe-Shenhai
Izisetshenziswa zekilasi A ezidizayinelwe i-Dust Explosion Zone 21 ibonakala ngezinga lokushisa eliphezulu elingaphezulu kuka-TA 85°C. Ezimweni lapho ukuqhuma kufanele kugwenywe, umoya ungaqukatha izinto ezivuthayo neziqhuma njengamagesi, umhwamuko, uthuli, kanye nemicu. Ukuqhuma kungenzeka uma lezi zinto zihlangana nezinhlansi, amalangabi, amazinga okushisa athile, noma izingcindezi zomoya ezithile. Ngakho-ke kubalulekile ukuthatha izinyathelo zokuvimbela ukuqhuma okunjalo.

| Indawo eqhumayo emoyeni ehlala ivela ngendlela yamafu othuli avuthayo, ikhona isikhathi eside noma kaningi. | Izindawo lapho iziqhumane ezisemoyeni zingavela khona noma ngezikhathi ezithile zivele njengamafu othuli oluvuthayo ngesikhathi sokusebenza okuvamile.. | Enqubweni yokusebenza evamile, indawo eqhumayo emoyeni esesimweni samafu othuli avuthayo ayinakwenzeka ezindaweni lapho ithuluzi likhona isikhathi esifushane.. |
Lokhu kugqamisa ukubaluleka kokulandela izindinganiso zokuphepha eziqinile, ikakhulukazi ezindaweni zezimboni lapho eziqhumayo izinto zokwakha zikhona. Ukusetshenziswa kwamadivayisi Ekilasi A, nendawo yawo ephezulu eshiwo izinga lokushisa, isu elibalulekile ekwehliseni ubungozi bokuqhuma. Lawa madivayisi aklanyelwe ukusebenza ngokuphepha ngaphakathi kwe-atmospheres eqhumayo ngokukhawulela izinga lokushisa lawo elingaphezulu ngaphansi kwezinga lokushisa elizungezile. ezivuthayo izinto zokwakha.
Ukuqaliswa kwalezi zimiso zokuphepha kuqinisekisa ukuthi ukusebenza ezindaweni eziyingozi kuhlala kuvikelekile futhi kungaqhumeki, ngalokho kuvikela kokubili abasebenzi nengqalasizinda.
