Bristol's city centre was locked down for around 45 minutes after a chemical alert at a hotel swimming pool.
Firefighters in breathing equipment were called to the scene at a hotel spa in Broad Street, which were alerted by the hotel's after a chlorine alarm was raised.
Seven fire engines, command units and an Environmental Response unit were called to the scene.
Crews in gas-tight suits monitored the levels of the chemical in the spa and found that although the levels of the chemical were raised, they did not pose a risk to public health, Avon and Somerset fire department said in a statement.
No casualties were reported and firefighters left the scene at 10am.
