As a business owner, if you have a Dry Riser on your premises, YOU are responsible for ensuring it is well maintained. It should be inspected and tested regularly to ensure it is functioning as it should.
In the event of a fire every second counts. The dry riser must function correctly; failure can seriously endanger property and, worse, lives. If it fails, the consequences could be catastrophic and, as a business, you could be liable for prosecution.
