Mabaka a lefatše la ho se tswa fireproof

Ko ditšheto tse pedi le tše nngwe ho qala hore dikgwedi tse di latelang moragoa, dikgwedi tse di latelang mabapi le tše di latelang mahareng, boemo ba bangata ke ho u sa e leng fa ho bontsha ho sebetsa ho bua ho fokotsoa ho ya ka fire flames,

arc flashes, le dilemollo tse tharo. Ko GUARDEVER, re sebelisa mehato ea ho fokotsoa ea fire (FR) eo e ne e tla ile ka lefatshe la sebopeho sa fetisiso

standards. Efe lefatše jwalo ke ho bolella ho sebeletseng ho sebopeho sa dilo tse pedi le tše nngwe ho tla sebedisitswe ho lateloa bangata bakeng sa hao:

• NFPA 2112: Sebopeho sa Fire Flame sa Dikgwedi
Tsoseletso ya ditšhabelo: Ditlhakore tsa mokhoro, ditlhakore tsa dikemisenti, le ditlhabologo tsa petrochemical.
Mabapi a go ne a le a gear FR a rona:

Kgato ea Lefatshe: Dibagano tse di latelang ASTM D6413 testing, ho boloka ≤10.2 cm char length le ≤2 sec afterflame.

Covering e fumana hore e bolella: E sebediswang ergonomically ho bontsha fa le manane a matla a akgilweng a a nne a a ka loketše.

Bopu ba Protection (TPP): E rating ≥50% ho boloka go re kgalekile 3-second flash fire exposure.
Fele le ho kgetheka tsebo? Dinehla tsa rona di latelang le NFPA 2112 di na le boleng, di fumaneha le di sebetswe go ya ka mokgwa wa lefelo la hlopho le le sa reng.

• NFPA 2113: Tsamaiso ya go hwetša dikilo tša FR le go dirisa
Go baetsa mathata: Tlola bokgetho le go ntšha thari ya dikilo.
Dinehiliso tsa rona:

Go hwetša ka dintšo tsa risiko: Rati diphintho tse pedišanang ka lekoko la hore lebaka la gagolego (fire e e leng, arc flash, go dirisa ditšelete).

Tlaleho le Tlhahlobo: Mabopo a ka boya mabapi le letsoho tse pedi le ho hae ho se tsamaiswa ditlhakiso tse pedi le 50+ (per ASTM F2757-09). Thupelo e bolokehileng ho hlahloba kapa ho tlhahloba motheo wa ho fumana lekgetho le kotsing.

tlhahlobo e ne e latelang.
Mopeli wa ho reka: Boikarabelo jwalo ka mabapi le ho boloka bokgoni le ho phethahatswe ke OSHA/NFPA.

• ASTM F1506: Bokgoni jo Arc-Rated ho Basadi ba Mafetole
Ho mafateng: Utilities, substations, electrical contractors.
Selemo sa rona e fumaneletsweng ho boloka ditšhemo tsa arc:

ATPV/EBT E tsepediwa: Tsepediwa morenong ASTM F1959 ho bolokela molao wa arc eo le 40 cal/cm² (HRC 4).

Ditšhemo tsa Multi-Layer: Ditšhemo tse dinnyeletseng (shirts, pants, hoods) le bohlokwa jwalo le ho hloka difofoloji tse pedi ho ya ka mabapi a lebitso la arc flash.
Bofelong jwalo le ho tsepediwa: Tsepediwa morenong le dumeleli tsa utility ea tse ngatafault currents ea 15kA+.

• ASTM F2733: Selemo sa FR ho sebetsa dikgweding tse pedi
Tšebeletso e tla e bile: Bokhetha ya Arctic, bokoneka ya mahareng, le ditshotlho tsa bosechaba jwalo.
Hlokomela rano:

Molao wa Matshepo: U sebelisitswe ka -25°C (-13°F) go nna lefelo lefele le kgile go na le diragatšišo tsa FR.

Go boloka dintlha: Dilo tsa go boloka go tswa ka mabapi le a re a ne a tla a fetileng go ne go tswa ka sweat, mokgwa o mongwe o tlhalosang go ne go tswa ka hypothermia.
Lekgetho la kasiteli: Ditiro tše 30% tse di latelwang go ya ka matshepo a jobe a rig teams go sebisitšwego gear e e bile go ya ka ASTM F2733.

Ke neng, setjhaba e bolokeha ho hlaboswa ka mabapi lefelo tse pedi le lekgethe tsena, ho reka mangolo e mong o ne a qala ke nyane, ke e bolella ho re fumana kamanyno ea hao:

Neke ha bile 1999 leile Guardever, re sebetsa ho tshwara ho ya ka mabapi lefelo tse twenty. Hae, ka ho hlokomela ditaelo tse pedi tsa mafelong a matsatsi a manane, setjhaba se se bokae le se se tsoele.

haore, ka ho hlokomela ditaelo tse pedi tsa mafelong a matsatsi a manane, setjhaba se se bokae le se se tsoele. Haore, ka ho hlokomela ditaelo tse pedi tsa mafelong a matsatsi a manane, setjhaba se se bokae le se se tsoele.
