Kuphulika-Umboni Mulingo wa Kuphulika-Umboni Wa Crane

Zofunikira zosiyanasiyana zamagulu osaphulika a cranes zimachokera kumadera osiyanasiyana oyaka ndi kuphulika.. Zofunikirazi zili m’magulu atatu akuluakulu:

Condition Category	Gasi Gulu	Woimira mpweya	Minimum Ignition Spark Energy
Pansi pa Mgodi	Ine	Methane	0.280mJ
Mafakitole Kunja Kwa Mgodi	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ
	IIC	haidrojeni	0.019mJ

1. Ma cranes a Class I osaphulika, adatchedwa Exd I;

2. Ma cranes a Class II osaphulika mafakitale, osankhidwa ngati Exd IIB T4 kapena Exd IIC T4;

3. Ma fumbi ophulika, osankhidwa ngati dip a21 ta t4;

Mkati mwa kalasi II, ma crace-upangiri wophatikizidwa monga flamemeroof “d” ndi otetezeka mkati “ndi” amasankhidwa ku IIA, IIB, ndi milingo ya IIC. Ma cranes okhala ndi malo okhala ndi IIB ndi oyenera ku IIA, pomwe ma cranes adavotera iic ndi yoyenera ku IIA ndi IIB.
