Testing Leaves For Starch

My HT is saying that this prac, which involves test tubes of hot metho, has been banned.
She says that it's because of occasions where the metho has been heated over a Bunsen and the fumes have ignited.
Has anyone else heard this?
We use hot plates to heat a beaker of water to boiling, then put the test tube of metho and leaf into the hot water.
