Zvinodiwa zvakasiyana-siyana zvekuputika-kuratidzwa kwezvikamu zve cranes zvinosimuka kubva munzvimbo dzakasiyana dzinopisa uye dzinoputika.. Izvi zvinodiwa zvinowira muzvikamu zvitatu zvikuru:

Condition Category	Gasi Classification	Anomiririra magasi	Minimum Ignition Spark Energy
Under The Mine	I	Methane	0.280mJ
Mafekitori Kunze Kwemugodhi	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ

1. Makireni eKirasi I anodzivirira kuputika, yakanyorwa seExd I;

2. Kirasi II indasitiri inoputika-inoratidza cranes, yakasarudzwa seExd IIB T4 kana Exd IIC T4;

3. Guruva rinodzivirira kuputika, yakasarudzwa seDIP A21 TA T4;

MuKirasi II, Makoni anodzivirira kuputika akaiswa muchikamu senge asingapise moto “d” uye zvakachengeteka “i” akaiswa muIIA, IIB, uye IIC mazinga. Cranes ane IIB chiyero akakodzera kune IIA nharaunda, nepo ma cranes akatemerwa IIC akakodzera kune ese IIA neIIB nharaunda.
