I try to stay away from my family when they are easily irritable or angry. With my husband and son I stop them and ask them "What's going on? Are you mad at me because you sound it? What can help?" I have to say it in a very calm and low voice. Their answer is usually screamed at me but after a while when they have to voice why they are angry they catch themselves.My husband does the same for me. If your scared call the cops.
