The other half of the mix has not been studied for worker security. It is a chemical concern mark with no toxicology or health info. This part contains amines, which serve as a driver; glycols blowing agents that respond with the foam; and phosphate, a flame retardant. This half of the spray polyurethane foam formula raises numerous concerns: What is the concentration of the fumes and vapors from these chemicals when spray foam is applied? Are the employees who are using the spray foam properly protected? What about others on site who are not using the spray foam and who are not wearing the very same personal protective equipment? The length of time does it require to ventilate the location after application? Exist cost-saving techniques for isolating and venting the fumes? We are currently researching these concerns.
