If a fire alarm said break glass could I kick the glass and use the hammer?

If a fire alarm said Break the Glass could I kick the glass and use the hammer? Would my underwear need to be readjusted after kicking the glass? Why would some people kick the glass and use the hammer? If they had a shoe on would it be better than taking off the shoe so you won’t step in glass. Have you seen a person kick the glass in a fire? How many kicks did it take? If you had to pull a handle how do you clear all the glass so you can pull it?
