Should anyone have any questions, please do not hesitate to contact Mike Lynch, President, Wheelblast, Inc. 1. The Wheelblast operation is not a typical spray finishing operation in that the process does not produce vapors that exceed twenty -five (25) percent of the lower flammable limit due to the airless spray technology, unconfined spray area of over three - hundred- seventy thousand (370,000) cubic feet, and natural atmospheric dilution. Data collected to date on the current alike outdoor operations have yielded no detectable combustible emissions as close as one (1) foot from the spray nozzle. An alr sampling protocol designed to establish that the spray process within the canopy does not produce vapors that exceed twenty -five (25) percent of the lower flammable limit shall and Implemented immediately upon commencing operations. The air sampling protocol shall follow the criteria of the American Industrial Hygiene Association and be designed to provide a confidence interval that vapors that exceed twenty -five (25) percent of the lower flammable limit. Periodic monitoring Intervals shall be established based upon the initial survey data to assure that the confidence Interval 18 maintained. The air sampling protocol and data shall be available to the Authority Having Jurisdiction at all times. 2. The canopy shall be of open type design with at least three - quarters (3/4) of the structure perimeter shall open to the atmosphere or protected by fire retardant insect protection products that restrict ventilation to not less than 400 feet per minute. The canopy shall be provided with a standard ridge vent traversing the entire length of the canopy. Mechanical dilution ventilation shall be provided to supplement the natural ventilation if Indicated by the air sampling protocol described above. The assumption, based on existing data, Is that vapors that will never approach twenty - five (25) percent of the lower flammable limit that would require supplemental mechanical ventilation. 3. A three (3) foot clear space shall be maintained on all sides and through the centers when objects are laid out to be sprayed to provide for an unobstructed and safe egress. Length of materials will dictate vertical or horizontal layout within the canopy in a manner to ensure aisles are available and maintained. In addition, a center aisle will be continuously maintained of approximately eight (8) feet in width to facilitate access 4, No motorized for employees m to ial handling equipment will be operated at any time with: R�vl� ICS canopy while spray activities are being conducted.
