ʻO 90% o nā pōʻino pahū ma muli o ke koho pono ʻole ʻana i nā mea hana!

He mea pōʻino nā pahū ʻoihana - akā hiki ke pale ʻia ka hapa nui. Inā ʻoe e hana i ka ʻaila a me ke kinoea, ka hana kemika, a i ʻole kekahi ʻoihana pōʻino, no ʻoe kēia alakaʻi. E aʻo pehea e koho ai i nā mea pahū kūpono i kūpono i nā kūlana honua a paleʻelua kāukanaka a me ka waiwai.

1. Hoomaopopo kaHōʻailona Pahū-Hōʻoia

ʻO kēlā me kēiahooiaiolawe ʻia ka mīkini i nā hōʻailona koʻikoʻi, e like me:
kinoea:Ex db ⅡC T6 Gb / Lehu:Ex tb ⅢC T85 ℃ Db

ʻO kēia codemanaʻos:

Ex db= Pale pale ahi (no nā wahi kinoea)

ⅡC= Kiekie loahui kinoea pilikia(hydrogen, acetylene)

T6= Ka wela o ka ʻili kiʻekiʻe ≤ 85°C (helu palekana loa)

ⅢC= Kiekie loahui lepo pilikia(nā metala hoʻokele e like me ka aluminika/magnesium)

ʻO kā mākounā mea hana hoʻoheheʻe pahūe hoʻokō i kēia mau kūlana, e hōʻoia i ka palekana loa.

2. Nā ʻano o ka pale ʻana i ka pahū (ʻo wai ʻoe e pono ai?)

※ Hoʻohana kā mākou huahana i ka Flameproof (Ex db), kūpono no nā noi ʻoihana kiʻekiʻe ma ka Apana 1/2.

3. E ʻike i kou Kaiapuni: Ke kinoea a me ka lepo

Kaiaea Pahu (Papa II)

ⅡA(Low risk) – Propane, butane

ⅡB(Medium risk) – Ethylene, nā kinoea ʻenehana

ⅡC(Pili kiʻekiʻe loa) – Hydrogen, acetylene

Nā Kaiapuni Pahu Lehu (Papa III)

ⅢA- ʻO nā pulupulu, lāʻau

ⅢB- ka lepo non-conductive (palaoa, lanahu)

ⅢC- ka lepo hoʻokele (alumimina, magnesium)

※ Uhi kā mākou mea hana i ka ⅡB, ⅡC (gas) a me ⅢC (ka lepo)—ʻo nā kūlana pōʻino loa.

4. He mea nui ka helu ana o ka wela—T6 ka palekana loa

※ ʻO kā mākounā mea hoʻopahū pahūua helu ʻia ʻo T6—ka mea kiʻekiʻe loahelu palekana no ka wela o ka ili.

5. Hoʻokaʻawale ʻana i nā ʻāpana pōʻino:E koho i ka lako pono no ka hoʻonohonoho

Wahi 0– Maunoho kinoea(e laʻa, i loko o nā pahu wahie)

Wahi 1–pinepine noho kinoea(e laʻa, kemika reactor, hana anawahi)

Wahi 2–I kekahi manawapilikia (e laʻa, hoʻouka wahowahis, nā wahi mālama)

LehuʻĀpanas

Māhele 20- Nā ao lepo mau (e laʻa, i loko o nā silos)

Mahele 21–Hōʻike pinepine i ka lepo(e laʻa, nā kāʻei conveyor)

Mahele 22- ʻIke ʻia ka lepo kakaʻikahi (e laʻa, nā leaks kānana)

※ Ua hōʻoia ʻia kā mākou huahana no Zone 1/2 (gas) a me Zone 21/22 (puehu).

Ka hopena: E koho pono, e noho palekana

ʻAʻole pili wale ka pale pahū i ka hoʻokō—e pili ana i ke kuleana. Me:

●ʻO Ex dbhoʻolālā,

●Nā palapala hōʻoia noKaiapuni IIC/IIIC,

●palekana wela T6, a

●Hoʻokō meATEX & IECEx

Ua hilinaʻi ʻia kā mākou mea hana pahū i nā kūlana koʻikoʻi o ka honua.

Mai hoʻopaʻapaʻa. Hoʻonui i ka palekana i kēia lā.
