Greetings @jada1! 
Astral projection is very exciting- good for you for jumping into it! 
I know there are quite a few others who have experimented and practiced astral projection before. Their stories and experiences have a lot of tips and tricks, so I recommend checking out the following discussions:
Guided meditations are a great way to ease into any new aspect of magick- following along with a guide can help to keep you safe and on track during your first few meditations 
And as for safety- the most important thing that comes to mind is making sure that your physical body is in a safe and secure space while you astral travel 
Good luck and blessed be!
