Greetings:
 
We've got an attic we need to clean out that unfortunately has been visited by pigeons over the years.  Most of the droppings are old but there has been some fairly recent activity also, despite attempts to keep them out.
 
What safety measures do we need to take for staff working in this area?  Gloves of course, but what is recommended in terms of face masks?   Do we need need the type of respirators (I'm not sure if this is the correct term) used in construction?
 
Your input is much appreciated.
 
Happy Holidays from the beautiful Upper Perkiomen Valley!
