Conclusions

After analDzin the data* e found that Methanol is a hihlD to,i and flamma0le

li1uid and 0eause of this propertD is danerous for 0oth humans and the en!ironment.

Indi!idual risG is reater and more danerous on a small radius from the soure

e,plosion and pronouned soial risG and threatens reater distane from the soure of

e,plosion.

Cue to the site loation* the effets of an e,plosion ould ha!e resulted in more

neati!e than if it ere plaed in free field.
