Correct spelling, explanation: safety is a noun made from a specific adjective – safe. It’s formed by adding the suffix -ty to its root. This suffix is attached to adjectives to form nouns that name or refer to a state or condition. There is no reason to spell this word saftey, because the right form is a combination of two elements: the adjective safe + the suffix -ty. Therefore, the only correct spelling is safety.

Definition of safety:
noun, the condition of not being in danger
Please, keep your seat belt fastened for your own safety.
I don’t want to go into the woods when it’s dark. I worry about my safety.

Incorrect spelling, explanation: the spelling is a mistake because it doesn’t match with the spelling of the noun, which is safe. A noun is derived from an adjective, so it must accord with the spelling of this part of speech. In this case, two letters (-t and -e) should change places. That’s why the only right version is safety.
