Are there any specific rules for handling weapons?

A few specific points on weapons handling are worth noting:

1. In general, weapons should be handled respectfully. Doing this shows respect for the owner of the weapons, and keeps present in your mind that these weapons can be deadly.
2. If weapons are laying on the floor, you should never step over weapons (yours, or anyone else’s).
3. You should only use someone else’s weapons after asking their permission
