Security

Security versus means of escape - My daughter is renting a flat in Glasgow which was broken into recently. The landlord was asked to fit additional locks on the sash windows but said he couldn't due to fire safety regulations. Is this correct, if so, are there any products on the market which would be deemed acceptable by the fire department and current legislation pertaining to fire safety with regards to hotels, care homes and rented property.
