Jon Lacey, West Sussex Fire and Rescue Service area manager for risk and improvements, said: “This fire is difficult to tackle because the material is highly flammable. With several hundred tonnes of household waste involved, the fire is burning slowly and is difficult to extinguish.
"At Westhampnett we have the added problem of the waste being inside a building which has suffered damage. This restricts safe access and also slows down the rate of burn.

“Additionally the site is alongside Westhampnett Lake and we are concerned that run-off of the large volume of water which would be needed to tackle the fire, does not cause serious contamination to the water courses which flow down to Pagham Harbour, a sensitive ecosystem.
“Our strategy has been to contain the fire while the wind direction has largely allowed the smoke to disperse across open land. However, mindful that we need to try and prevent smoke affecting residents and businesses, we have explored ways to tackle the blaze with minimum risk of contamination.”

Advice from West Sussex County Council to residents living in the area is not to be concerned if they smell smoke in the air this weekend.
The advice from Public Health England is where the smell of smoke is detected, to stay indoors where possible and keep windows and doors closed. Exposure to smoke is more likely to affect people who have existing breathing problems, lung and heart conditions and if any symptoms persist to call NHS 111 or contact your GP.

Steve Read, Director of Energy, Waste and Environment at West Sussex County Council said: “There is a risk that some residents in the Chichester area could be affected by a smoky smell from this Friday afternoon into the weekend.
“We apologise for any concern this causes and assure residents and businesses we have explored all avenues to reduce the impact of the blaze.”

A spokesman for the site's management company, Viridor, said earlier this week that a likely cause of the blaze is lithium ion batteries which are found in mobile phones, laptops, toys and other items.
Staff are looking to restore a minimum service at Westhampnett as soon as practical but it is likely to be next week at the earliest before we can say when that will be.
If necessary, the nearest alternative sites are Bognor Regis, which will be open seven days a week for the time being, Worthing, Billingshurst and Littlehampton. Please note Bognor and Littlehampton are not able to accept trailers.
