Ndondomeko yochotsera chizindikiro cha lock out

Zipangizo zotsekera ma valve pachipata ndi chida chofunikira kwambiri chotetezera kuntchito kulikonse komwe kumafunika kuimitsa ma valve. Zipangizozi, zomwe zimadziwikanso kutivalavu LOTO (lockout/tagout), zapangidwa kuti zipewe kugwira ntchito mwangozi kapena mosaloledwa kwa ma valve a chipata, kuonetsetsa kuti chitetezo cha ogwira ntchito ndi kukhulupirika kwa zida.

Zipangizo zotsekera ma valve pachipataamagwiritsidwa ntchito kwambiri m'mafakitale monga mafuta ndi gasi, mankhwala, kupanga ndi mautumiki apakhomo komwe ma valve amafunika kuchotsedwa kuti akonze, kukonza kapena kuchita zinthu zina. Zipangizozi ndi zosavuta kugwiritsa ntchito ndipo zimathandiza kwambiri popewa kutulutsidwa kwa zinthu zoopsa, kutayika kwa mphamvu, kapena kuwonongeka kwa zida.

Chimodzi mwa zinthu zazikulu zazipangizo zotsekera ma valve a chipatandi kusinthasintha kwawo. Amapezeka m'makulidwe osiyanasiyana kuti agwirizane ndi mitundu yosiyanasiyana ya ma valve a chipata, kuphatikizapo ma valve oyendetsedwa ndi mawilo amanja, ma valve oyendetsedwa ndi unyolo, ndi ma valve oyendetsedwa ndi mawilo. Izi zimatsimikizira kuti angagwiritsidwe ntchito m'njira zosiyanasiyana, zomwe zimapangitsa kuti akhale ndalama zofunika kwambiri ku bungwe lililonse.

Kuwonjezera pa kusinthasintha,zipangizo zotsekera ma valve a chipataZapangidwa poganizira kulimba ndi kudalirika. Zapangidwa kuchokera ku zipangizo zapamwamba kwambiri, monga ma polima olimba a thermoplastic, kuonetsetsa kuti zimatha kupirira nyengo zovuta za mafakitale. Izi zikutanthauza kuti zimatha kupereka ma valavu okhazikika bwino kwa zaka zambiri popanda kufunikira kusinthidwa pafupipafupi.

Kuphatikiza apo,chipangizo chotseka ma valavu a chipataYapangidwa kuti iikidwe mosavuta ndikuchotsedwa kuti igwiritsidwe ntchito bwino komanso mosavuta. Yapangidwa mwapadera kuti igwiritsidwe ntchito mwachangu komanso mosamala pama valve, kuletsa kulowa kapena kugwira ntchito kosaloledwa. Izi zimatsimikizira kuti ogwira ntchito amatha kupatula valavu molimba mtima popanda chiopsezo cha ngozi kapena ngozi.

Ponena za chitetezo,zipangizo zotsekera ma valve a chipatandi gawo lofunika kwambiri pa dongosolo la LOTO la bungwe lililonse. Amapereka njira yodalirika komanso yothandiza yopewera kugwiritsa ntchito ma valve mwangozi kapena mosaloledwa, zomwe zimathandiza kuonetsetsa kuti chitetezo cha ogwira ntchito ndi zida zawo ndi zolondola. Mwa kuphatikiza zida izi mu njira zawo zachitetezo, mabungwe amatha kusonyeza kudzipereka kwawo kuteteza antchito ndikupewa zoopsa zomwe zingachitike.

Powombetsa mkota,zipangizo zotsekera ma valve a chipatandi chida chofunikira kwambiri chotetezera kuntchito iliyonse yomwe imafuna kuimitsa ma valavu. Amapereka njira yosinthasintha, yolimba komanso yodalirika yomwe imaletsa kugwiritsa ntchito ma valavu a pachipata mwangozi kapena mosaloledwa, zomwe zimathandiza kuonetsetsa kuti chitetezo cha ogwira ntchito ndi zida zake ndi zolondola. Chifukwa cha kugwiritsa ntchito kwawo mosavuta komanso moyenera, zidazi ndi ndalama zofunika kwambiri kwa bungwe lililonse lomwe likufuna kupititsa patsogolo njira zawo zachitetezo ndikuteteza antchito awo.
