My friend is from work is pregnant and she's so excited.  I'm excited to, but also worried since we work in a lab and we have to be very careful of the chemicals. 
I just found out a friend at work is pregnant!

Second actually. have to be a bit careful though.  We work around some dangerous chemicals.

That sounds scary. How often do children of the employees at your work end up harmed because of the chemicals?
assistant
Not often.  We have a really good Health and Safety program.
