If the ‘feeling unsafe’ is genuine
It's vocabulary appropriated from people with trauma, along with the word 'triggered', which as usual has been overused for effect in the wrong contexts and has the effect of diluting, confusing and reducing the understanding for and support of those who needed that language in the first place.
I have never yet seen any therapist or therapeutic intervention for adults with actual trauma that advises a patient to expect others to maintain their emotional safety, know their triggers and take responsibility for their feelings and reactions. Unless you're working with a young child and you're their parent, this isn't a healthy approach in any way, your needs, your feelings and your boundaries are always your responsibility to manage.
I am not your mummy. I am not going to have a codependent relationship with you. To borrow a favourite phrase, you need to 'educate yourself' on living with and overcoming trauma, instead of borrowing the bits of vocabulary that you like and using them for effect to get others to meet your needs for you. Healthy grown ups don't do this.
