Merseyside Fire and Rescue Service (MFRS) is in attendance at an incident on Marion Street, Birkenhead.
Crews were alerted at 23.25 and on scene at 23.30. The incident required four engines on scene.
Crews arrived to find a factory unit measuring approximately 80 metres by 40 metres with smoke issuing from it.
Upon arrival, four firefighters wearing breathing apparatus (BA) were committed to the building with a main jet hose.
The incident is ongoing. Due to large volumes of smoke and fumes, residents nearby should keep doors and windows closed. If you have an existing medical condition, keep medicines or treatment nearby and if any ill effects are experienced dial NHS 111 for advice.
UPDATE 09.45 – Thursday 14 August
MFRS crews have worked diligently through the night to bring this incident to a positive conclusion and remain at scene.
A tactical plan has been established and the environment agency have been informed. Fire Service personnel are also liaising with the responsible person.
Following a comprehensive search of the premises, no sign of fire was found. Crews located a tank within the factory unit as the area of origin for the issuing smoke yesterday evening.
Firefighters in BA have routinely applied water to the external walls of the tank to cool the affected area and monitor temperatures, which have continued to decrease overnight.
Although the number of Fire Service resources at scene has been scaled down, this remains an ongoing incident, please continue to avoid the area.
