In I got It!
There are Safer(book) Segulos
The book of Raziel the Angel is not the only segulah for being rescued from fire.
The book of Raziel the Angel was the second book to be written from the creation of the world (the first one being the book of Adam), and was handed to Adam by G-d, through Raziel the Angel.
Adam passed the book over to his son, who later passed it on to his descendants, until it was handed to our forefather, Abraham.
Many Segulahs are attributed to this book: safeguarding, prevention of burglaries and fires, and more.
There are other known Segulahs for being rescued from fires, such as arousing for Tikkun Chatzos, the re-kindling of the Havdalah candle after its initial extinction and the host's escorting of the guests who leave his house.
