Krayteria fɔ Ritaya fɔ Kɔt

 

Akɔdin to ASME B30.9 , dɛn fɔ pul wan sling frɔm savis we:

 

• Di kɔt, te, ɔ snag we de mek di kɔr yan dɛn kɔmɔt na do —wans di ɔda layt we de protɛkt di ɔda layt dɔn kɔmprɔmis, di fayv dɛn we de bia lod kin pwɛl

• Ol ɔ kray wata na di wɛb we de go insay di ful tik

• Eni kot we de ridyus di webbing width bay wan signifyant amount

 

Per OSHA’s Guidance on Safe Sling Use,  dɛn rayt ol, tear, kɔt, abrasive wear, ɔ snags pan di kɔndishɔn dɛn we nid fɔ pul am wantɛm wantɛm na savis . Di Kanada Sɛntral fɔ Ɔkupeshɔn Ɛlth ɛn Sɛfty (CCOHS) tɔk bak se if pɔsin kɔt, kɔt, sna, ɔ ol na di sling bɔdi na sayn dɛn we pɔsin kin si fɔ sho se i dɔn pwɛl we i nid fɔ pul am.

 

Fɔ no pɔsin we pɔsin kin si:

 

• Smɔl sɔfays kɔt —na di fayba dɛn nɔmɔ we de ɔp de afɛkt; kin akseptabl if nɔ kɔr ɛksplɔz

Kritikal not:  Ivin 10% edj kot kin ridyus sling kapasiti bay 35% . Dis na di rizin we mek ASME B30.9 nid fɔ pul we ɛni kɔt rili kɔmprɔmis di sling in wit ɔ strɔkchɔ.

Krayteria fɔ Ritaya fɔ Abrashɔn

 

Per ASME B30.9 , wan sling fɔ kɔmɔt na savis we:

 

• Abrasive wear we pasmak de de—wear we de mek di kɔr yarn dɛn kɔmɔt na do ɔ we de ridyus di sling in krɔs-sekshɔn bad bad wan

• Surface abrasion dɔn west tru di ɔda wɛb to di lod-bearing kɔr

Fɔ no pɔsin we pɔsin kin si:

 

• Layt surface fuzzing —nɔmal frɔm yuz; akseptabl

• Frayed edges —i kin akseptabl if i smɔl, bɔt inspɛkt ɔltɛm

• Eria dεm we dεn dכn dכn —we de sho di insay plies כ di kכr yarn dεm; i fɔ dɔn ritaia

• Fayba we gɛt paoda bitwin di strɛch dɛn —de sho se di abrashɔn dɔn go bifo

 

Lishenflex in lab data sho se sling we dɛn yuz we nɔ gɛt kɔna protɛkta kin lɔs te to 50% pan dɛn trɛnk insay wan lif bikɔs ɔf kɔnsɛntret abrashɔn na di kɔntakt pɔynt. Kɔna protɛkta nɔto opshɔnal —dɛn impɔtant fɔ mek sling liv lɔng.

Per ASME B30.9 , wan sling fɔ kɔmɔt na savis we:
