Cov khoom no thiab nws cov ntim yuav tsum tau muab pov tseg raws li cov kev cai hauv lub tebchaws thiab hauv cheeb tsam.
Cov khoom no muaj cov kuab tshuaj volatile thiab yuav tsum tsis txhob noj. Cia kom deb ntawm qhov chaw kub, qhov hluav taws xob, hluav taws kub, thiab qhov chaw kub. Siv cov cuab yeej uas tsis yog-tseem ceeb, khaws cov thawv kaw kom nruj, thiab siv cov khoom tawg- pov thawj hluav taws xob uas muaj qhov cua txaus.
Rau kev sib cuag ntawm daim tawv nqaij, tshem tawm cov khaub ncaws tsis huv thiab ntxuav nrog xab npum thiab dej. Rau qhov muag pom, yaug nrog dej kom ntau; nrhiav kev kho mob yog tias tus mob hnyav.

Nyob rau hauv cov ntaub ntawv ntawm to, tsim dikes los yog khawb pits kom muaj cov spill, npog nrog ua npuas ncauj kom txo tau vapor txaus ntshai, thiab yog hais tias ua tau, hloov mus rau lub tank tsheb los yog tshwj xeeb ntim ntim rau rov qab los yog thauj mus rau qhov chaw pov tseg pov tseg. Rau kev tua hluav taws, siv cawv- ua npuas ncauj, carbon dioxide, hmoov qhuav, lossis xuab zeb; dej tsis zoo.
Kev ruaj ntseg yuav tsum tau khaws cia rau hauv qhov txias, zoo- lub tsev tso cua txias, kom deb ntawm qhov hluav taws kub thiab qhov cua sov, ua kom lub thawv kaw, thiab tswj qhov kub ntawm 5 txog 30 degrees.
