If there was glass on a fire alarm can you kick it?

If there was a fire and you needed to break the glass would it be normal to kick it? How many kicks would it take a person to kick the glass? Could you also use the hammer after kicking? How would you pull the handle after breaking the glass? Would you need to clear all the glass away by kicking some more or by using the hamme. If you don’t kick strong enough will the glass break in increments? Could you kick a few times as opposed to one hard kick?
