Another Safety-related question: We would like to use a spray booth with windows to demonstrate SPF application to our sales force and potential customers. Does anyone know of guidance documents or air monitoring studies that would indicate what type of respirator would be required inside the booth and how long the customer should wait outside the booth before being able to view up close and touch the finished foam?

It's mixed with sprayer, and trimmer and then they switched sometime and then switched back. the whole time, they didn't have any exhaust/intake ventilation within the space.

The industry is taking the conservative approach and recommending 24 hours after application to let building occupants into a sprayed area. So taking the same conservative approach, you probably should have them wear a air purifying respirator after the ventilation has cleared the air so that fumes are dissipated. It is overkill, but will provide you with less liability if someone claims that they were over exposed.
mason Posted: Jun 29, 2011 06:21 PM	As to your original question, you can have air monitoring of the area during application to determine if an air purifying respirator could be used based on your ventilation. You would not want more than 10 times the PEL in the area at any time. OSHA requirements are 0.02 ppm and NIOSH recommendations are 0.005 ppm. OSHA is regulatory, NIOSH is a recommendation but is used if you want to be conservative to protect against chemically sensitive individuals.
