Consumer Switch Rooom Left Unlocked for Whole Nite on 9 Mar 2014

This consumer switch room was left open
for the whole nite on 9 March 2014 (sun)

 

Is this a breach of security?

What happens if there is someone who went in,
got shocked
or
who is out to create trouble and sabotage
the entire building?

 

 

I called up the EMSU hotline and the
door was locked thereafter.
