Continuation Sheet for Part II, Section B

The new substance is incorporated at approximately {    } w/w of an {   
        } coating.  The {         } coating will then have its viscosity
adjusted in preparation (Worker Activity A) for spray application. 
Workers may be exposed to the new substance at {    } w/w in solution
during this operation. Workers are provided with personal protective
equipment as appropriate.

Application of the coating can vary by customer and site. Application
typically occurs via robotic or other automated spray equipment without
the presence of any workers.  However, workers may be exposed to the new
substance in the form of an aerosol during spraying of hard-to-reach
areas and touch-up applications (Worker Activity B).   Engineering
controls are used to reduce exposure, and workers are provided with
personal protective equipment as appropriate, which may include
respirators, gloves, protective clothing and eye protection.  Allowing
for break relief or job rotation, the number of workers may double for
those involved in some part of this worker activity.  The {            }
manufacturers usually employ a certified industrial hygienist in their
product safety department to assist in hazard assessment as needed. 

During robotic or automated spray operations, approximately 70% transfer
efficiency is attained.  The method is horizontal reciprocal spray with
reclaim device.  The application of the coating occurs in large
water-washed down-draft booths designed to pull overspray away from
workers.  All overspray is accumulated in the form of sludge, which will
either be incinerated or landfilled in RCRA approved landfills (Release
Point 4).  The wash-water in these down-draft booths is treated on site
prior to release to POTW, therefore it is expected that no discharge of
the new substance will occur to any local POTW.
