FWIW, I am a certified lead inspector and old house owner. Lets see if I can quickly clarify some lead hazard issues.
First, dry scraping and heat guns are the worst. They both expose you to the worst form of lead (ingestion and inhalation).
The safer way to strip is using liquid stripers. They keep the dust from getting airborne and present a lesser hazard.
There is always a risk of lead exposure if lead paint is present. Try and work outside as much as possible (remove doors, etc.). The first rule in lead training classes is that we want to be 'lead safe' because it is very hard to be 'lead free'.
I can give you plenty of suggestions on proper handling if you would like but I would need some more details on what you are using/striping and your household status (kids, pets, etc.).
