One of the two men killed when a fireworks depot exploded has been named.
Brian Wembridge, 63, died with a 49-year-old colleague after going to the scene of a fire at Festival Fireworks in Shortgate, near Lewes, East Sussex, on Sunday.
Sources said Mr Wembridge, a former firefighter, was employed by East Sussex Fire & Rescue Service as a support officer whose roles included photographing and filming fire scenes.
An investigation is under way into how the tragedy happened.
Twelve other people - nine fire service staff, two members of the public and a police sergeant - were also injured when the contents of the factory began exploding after the emergency services arrived at the scene.
The brigade's chief fire officer Des Prichard said the investigation was likely to take "many weeks". Mr Prichard said a 200-yard exclusion zone was still in place around the scene of the fire due to fears that acetylene gas canisters may explode.
Speaking at a police cordon, Mr Prichard said an Army bomb disposal unit had been deployed and its remote-controlled vehicle was being driven into the heart of the factory to assess the state of the gas cylinders.
The explosions at the depot were so loud they were heard by people in the town of Uckfield, some 12 miles away. The blasts shook nearby houses and sent debris flying through the air. With fireworks still shooting from the blaze several hours later, the emergency services were forced to retreat from the scene, leaving the flames and explosions to wreck the depot and a nearby house.
The drama began shortly before 2pm on Sunday on a remote industrial estate. Members of the family-run company fled after discovering a fire had broken out. At first, 10 fire engines and crews were dispatched, but more officers were called in as the scale of the blaze became apparent. The biggest explosion, which residents compared to a bomb going off, was at about 3pm.
Jason Winter, nephew of Festival Fireworks owner Martin Winter, said of his family: "They have literally got the shirt that they're wearing at the moment, that's it. They have lost everything."
