Hello team, I'm new to this forum and would be grateful for some advise or to be pointed in the right direction. I work in an academy (Secondary school) with 900 students on roll. Due to the number of false alarms of late the following question has been asked. Is it acceptable to silence the alarm and carry out alarm verification/verifying before signalling a full evacuation? I understand it is acceptable for trained persons to investigate the presence of a true fire; but should a evacuation take place first or could some kind of 'Stay put' policy be put in place? Thank you in advance for any help you can give. Kind regards, Chris.
