Is it appropriate for a Christian to pray for angelic protection in the face of physical or natural dangers?

Consider the following examples: Imagine a Christian mother driving her car with her children in the back seats when suddenly, they are surrounded by robbers intent on stealing everything and possibly harming her kids. In such a terrifying situation, would it make sense for her to pray for angelic protection? Or consider a scenario where a Christian encounters a pit bull 100 meters away that suddenly charges toward them with aggression. In that moment of imminent danger, would it be reasonable for the Christian to pray for angelic intervention? Lastly, picture an elderly Christian man in a bedroom with a baby when a fire unexpectedly breaks out, blocking all exits. In such a desperate and life-threatening situation, would it make sense for him to pray for angelic protection, hoping for divine intervention to save them?
