4	Frequently Asked Questions Q - Why VCI technology for boilers and related components? A - Vapor Corrosion Inhibitors (VCI) function by releasing or vaporizing into the air space and laying out on all the metal surface a protective film. This technology is ideally suited for dry lay-up (although wet lay-up is possible) and can protect for up to two years! Anytime a boiler or related equipment is non-operable and can be drained, VCI technology is an excellent choice. Q - Can I inspect the boiler with this material inside? A - The vapors are not hazardous. However, it is suggested that appropriate vessel entry safety procedures be followed. Protective clothing should be worn to avoid/minimize skin contact with any residual product in the boiler. Q - Can I start-up the boiler with this material inside? A - Yes, the products are water soluble. Ideally, a fill & flush would be performed prior to start-up but is not absolutely necessary. Boilers with a history of foaming and carryover problems should fill & flush first. Q - How do I determine dosage? A - Dosage is determined strictly based on system volume unless otherwise noted. Q - How do I assess performance? A - Corrosion coupons have been used or you can simply visually inspect the boiler routinely. A retractable corrosion coupon holder can be rigged if vessel opening is not desired or practical.

7	See Diagram above for ILLUSTRATION How our VCI Works 1. VCI products contain inhibitors which sublime or emit into the air space. In order to ensure all metal surfaces are protected, enough VCI product must be added so that enclosed air space is saturated with gaseous VCI molecules. This vaporizing ability enables VCIs to protect metals without direct application to the metal surface. A close up view illustrates how the VCI molecules layout onto the the metal surface (as a barrier) once equilibrium/saturation is reached in the vapor space. The slightest amount of moisture will wet & ionize the molecules to form a barrier that will effectively protect metal surfaces for up to two years.
