Lime for q21q21 or help reading an MSDS

[boonefrog]

this Bonide Lime (PDF) seems like generic garden lime that the tek calls for - is it?

Section II: Hazardous ingredients/identity
"Calcium Oxide CAS# 1305-78-8
Silicon Dioxide CAS# 7631-86-9
Magnesium Oxide CAS# 1309-48-4"

and Section III: Physical/Chemical ingredients
"CHEMICAL NAME: Calcium Hydroxide"

Whats the difference here? Should I assume Section 2 is the ingredients that somehow were used to make the Calcium Hydroxide??
