East Sussex Fire and Rescue Service is continuing to work at the scene of the Newhaven waste fire - but the operation has been scaled down with one fire engine remaining at the site.
A spokesman for the fire service said firefighters are working alongside staff from the operators to clear the waste, which remains smouldering and burning in parts at Skip It at North Quay Road.
The spokesman said: “This is taking time due to the amount of waste which was involved in this incident (around 200 tonnes) and the need to ensure that there is no chance of re-ignition.
“This work is causing some smoke in the area, despite efforts to minimise this.
“We would like to remind the public of Public Health England’s advice.
“Residents in areas affected by the smoke should stay indoors and keep their doors and windows closed. Any smoke can be an irritant and as such, if people need to be outdoors, they are advised to avoid outside areas affected by any smoke or ash, or to limit the time that they spend in them.
“Motorists who have to travel through the smoke should keep windows closed, turn off air conditioning and keep their air vents closed.
“Some of the substances present in smoke can irritate the lining of the air passages, the skin and the eyes. Respiratory symptoms include coughing and wheezing, breathlessness, sputum (phlegm) production and chest pain. If symptoms occur, people should seek medical advice or call NHS 111. Smoke can worsen existing health problems like asthma.”
