Only after the smell of ozone is not heard can personnel enter the room to work.

Thaum lub sij hawm txhim kho, qhov kev hloov pauv thiab lub teeb pom kev zoo yuav tsum sib txawv, thiab yuav tsum siv cov cim ceeb toom; Daim duab tsim yuav tsum tau qhia tias nws yog nruj me ntsis txwv tsis pub rau nruab nyob rau hauv parallel nrog lub teeb pom kev zoo hloov. Nyob rau hauv Tanghai lub tsev kho mob project, lub teeb hloov ultraviolet yog tsim los rau 18m saum av; Lub teeb ceeb toom liab raug ntsia saum lub qhov rooj sab nraum zoov kom tiv thaiv kev nkag tsis tau. Hauv cov chav kawm theem pib thiab theem nrab thiab lwm qhov chaw, nws yog qhov zoo tshaj rau kev tswj hwm hauv nruab nrab hauv chav ua haujlwm.
