G. If applied by brushing, the coating shall be brushed on in 1 direction and then smoothed in a direction at right angles thereto, so as to produce as uniform thickness of coating and as complete coverage as possible. Such 2 directional brushing shall be considered as "1 coat" within the meaning of these Specifications. H. Sufficient time shall be allowed for each coat to dry properly and in accordance with the manufacturer's recommendations before applying the next coat. All areas cleaned shall be primed within 8 hours of being cleaned. Any areas developing a film or rust shall be re -cleaned before priming. Finish coats of paint shall be free of holidays, runs, drips, or sags. Any areas showing such defects in the prime coat shall be corrected prior to application of the finish coat. Any areas showing defects in the finish coat shall be scraped and repainted to the satisfaction of the Engineer. 3.06 VENTILATION AND SAFETY A. The Contractor shall maintain adequate and continuous explosion -proof ventilation during all surface preparation and coating operations, and during all re -coat and curing periods. This ventilation shall be of the suction type and shall be of sufficient capacity to maintain throughout the tank interior a clear atmosphere that is well below explosive and toxic limits. B. Arrange the ventilation system, including all fans and temporary ductwork, so that fresh air is drawn into the tank at the bottom and is exhausted at the top with an upward air movement pattern within the tank that permits no still air spaces to exist in any area. Give particular attention to floor level or lower spaces, and pocket areas where heavier-than-air solvents and particulate matter are likely to accumulate. Said ventilation shall be sufficient for the removal of dust, coating fumes, or other volatile gases and moisture to such an extent as to prevent any undesirable accumulation and prevent hazard to the workmen or the Work. C. All electrical equipment, tools, and ventilation fans shall be explosion -proof and/or non -sparking and shall be maintained in good working order. Spray equipment shall be as recommended by or acceptable to the coatings manufacturer and shall be thoroughly cleaned before and after use with the appropriate cleaning solvents. D. Provide adequate explosion -proof lighting during all surface preparation and coating operations. This lighting shall be sufficient to illuminate clearly the working area without shadows. E. In the event heating devices are used, they shall be explosion -proof and of the type that do not exhaust sooty or oily residues or any other contaminants into the tank. Only indirect heating units can be used which will not cause the products of combustion to condense. F. Prior to use, store all coating materials in a secure area which shall provide protection from weather and temperature below 60 degrees F. The area shall be maintained in a safe, neat, and clean manner and free from fire, explosion, or other hazards. G. All Work shall be performed in a safe and orderly manner, all in compliance with the standards as prescribed by OSHA and the Minnesota Department of Labor and Industry, Division of Accident Prevention. The Contractor will be required to comply with OSHA Regulations, including 5205.1000 through 5205.1040 and 5067.0300 for Confined Space Entry. Management and supervisory personnel shall be responsible for employee training and compliance with this policy. H. Securing Tank Openings: Adequate grating or grills will be securely attached to all openings not otherwise secured at the end of work each day until Work commences again and during the final cure after all interior coatings have been applied, until such time as the tank is filled with water WATER TOWER REPAINTING © 2012 Stantec 1 193803415 09 91 55 - 9
