Research By Dr Carrie Redlich – SPF

Many of us Spray Foam families have been to see Dr Carrie Redlich at Yale University Hospital. She is researching the safety of SPF on construction workers. Clearly there is a concern about this product.
What about the homeowners living with chronic off gassing??? How will this affect our long term health?
The construction workers are suppose to wear protective equipment, but the homeowner has no protection.
When will someone research US???
