Qarxi-Caddaynta Heerka Qarxinta-Celinta Wiishka

Shuruudo kala duwan oo loogu talagalay kala soocida aan qarxin ee wiishashku waxay ka soo baxaan jawiyo guban kara iyo kuwa qarxa oo kala duwan. Shuruudahani waxay u kala baxaan saddex qaybood oo waaweyn:

Qaybta Xaaladda	Soocidda Gaaska	Gaasas matale	Dabci Ugu Yar ee Spark Energy
Hoosta Miinada	I	Methane	0.280mJ
Warshado ka baxsan Miinada	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ
	IIC	Hydrogen	0.019mJ

1. Fasalka 1-aad wiishash aan qarxin, loo qoondeeyay sida Exd I;

2. Fasalka II wiishyada qarxinta warshadaha, loo qoondeeyay sida Exd IIB T4 ama Exd IIC T4;

3. Wiishashka qaraxa boodhka u adkaysta, loo qoondeeyay sida DIP A21 TA T4;

Gudaha fasalka II, Wiishashka aan qarxin ayaa loo kala saaray sidii ololka “d” iyo ammaan gudeed ahaan “i” waxaa loo kala saaraa IIA, IIB, iyo heerarka IIC. Wiishashka leh qiimeynta IIB waxay ku habboon yihiin bay'ada IIA, halka wiishashka lagu qiimeeyay IIC ay ku haboon yihiin labada deegaan ee IIA iyo IIB.
