<human>: Can you summarize the given text in a few sentences?

Hi everyone. I live in an old building in California that has signs posted (Prop 65) that state the facility contains asbestos. My kitchen linoleum was in horrible condition and after a recent housing authority checkup she said she was forced to change it. I came home the other day and say two landscape workers casually tearing it out and laying down new linoleum. I didn't think anything of it at first but now I am concerned that their process may have contaiminated my entire living room and kitchen. Can someone please offer insight as to what I should do to protect my health?
<bot>: Landlord changed old linoleum (which prob contained asbestos) but didn't use a professional service. Should I be concerned about my health? What should I do?
