Dentist pulls out teeth but not all the fire safety stops
" " Fire doors help to contain fire and smoke if there is fire in a building. To function properly, they need to be able to close automatically in case of a fire or need to be kept close in the first place. Wedging fire doors open is dangerous, as the smoke and fire will now spread unhindered. If you want to keep fire doors open for air circulation or easy of movement you need to use fire door retainers.
