During a major fit, which of the following actions can help protect a casualty?

Padding the area around the head during a major fit is an essential action to protect the casualty from potential injury. Seizures can cause involuntary movements and can result in the person hitting their head against hard or sharp surfaces, leading to serious injuries such as fractures or lacerations. By providing padding, such as a jacket, blanket, or any soft material, you create a safer environment that minimizes the risk of further harm.

This approach is in line with first aid guidelines, which emphasize the importance of ensuring the casualty's safety during a seizure rather than attempting to restrain or manipulate them. It is vital to allow the seizure to run its course while providing protection and support. This method ensures that you are considering the casualty's well-being and reducing the chances of complications during such an episode.
