Always use ice for the first 48 hours after a new injury. Heat might sometimes feel better, but it doesn't help with inflammation from the injury, so it doesn't promote healing. Even an old injury that shows signs of inflammation should be cold instead of heat. When it is an old or reoccurring injury (called chronic), heat is more help. If your back gets stiff from where you pulled it a few months ago, heat will help to loosen it up and ease the ache.
"If you suspect that you have a neck injury, you should see a medical professional to determine the nature and severity of the injury. For a stiff neck or shoulders, you should try to rest and gently massage the area. Also, always use an ice pack to your injury, do not apply heat."

Yes you should use a AED on a person that has a electrical shock injury.
It really depends on which type of injury occurred so that you can determine whether to use heat or ice. If the position is no pain-free, use ice. If the position is pain free with movement, use heat.
Usually you should apply ice for the first day or two after an acute injury and after that heat. If it is a chronic irritation apply ice after use and heat when trying to warm up and loosen up.
Manual handling of materials can lead to injuries such as sprains, strains, and back injuries. It is important for workers to be properly trained in safe handling techniques and to use mechanical aids when possible to reduce the risk of injury. Employers should also provide ergonomic workstations and regular breaks to prevent musculoskeletal injuries.
Typically you would use a heat pack (or hot water bottle etc) for a muscle injury. If you have pulled a muscle, hot (or cold) treatment will soothe the area
When the are of the injury is inflamed, you should put ice. Follow the RICE method, REST, ICE, COMPRESS and ELEVATE. Once swelling has subsided (about 5 days), you can start to use heat to promote blood flow and improve healing.
