Yorkshire Ambulance Service bosses are urging people to stay safe in the run up to Bonfire Night.
They say they expect to see a number of patients with firework and bonfire related injuries as they do each year.
Dr David Macklin, Executive Director of Operations at Yorkshire Ambulance Service, said: “Over the next few days our staff will treat a number of patients, children and adults, ranging from those with minor burns to those with more serious, life-threatening injuries.
“When used properly fireworks are safe and accidents are avoidable, but they can cause devastating injuries if safety precautions are not followed.
“We strongly recommend that people attend a professionally-organised public display but if you are planning to host your own event, please make safety your main priority to ensure everyone has a good time without getting hurt.
“In the event of an accident with fireworks or fires you need to act quickly. If the patient is alight, extinguish any flames by rolling them on the ground.
“Use cold water to cool the burned area and reduce pain. Do not remove burned clothing which has stuck.”
