VCS Category: The specified cargo's prcvisional classification for vapor @ntrol systems. Category I (No additional VCS requirements abow those for benzene, gasolines and crude oil) All requirements applying to the handling of oil and hazardous materials in Titles 33 and 46 Code of Federal Regulations (CFR) apply to these cargoes. Those specifi€lly dealiqg fiilh vapor cont-ol systems are in 33 CFR '155.750, 33 CFR 156.120, 33 CFR'156.170,46CFR35.35and46CFR39. Ihecallotankventingsystemcalculations(46CFR39.20-11)andthepressuredrop€lculations(46CFR39.30-1(b)) must use appropriate friction faclors, wpor densities and vapor growth rates.

Category 2 (Polymerizes) Polymerization and residue build-up of these cargoes €n adversely affect the vessel by fouling safety componenets and restricting vapor flow which could lead to €rgo iank overpressurization. The vessel's owner must develop a method of ensuring all VCS safety components are functional and polymer build-up is not causing an unsafe @ndition due to increased presure in the vapor control piping and €rgo tanks. The method shall be acceptable to the lo€l Officer in Charge, lvlarine lnspection. ThisisinadditiontotherequirementsofCategoryl.

Category 4 (Polymerizes and highly toxic) Must @mply with requirements of Categories 1, 2 and 3.

Category 5 (High vapor pressure) VCS pressure drop €lculations for cargoes with a vapor pressure greats than 1 4.7 psia at 1 1 5 F must take into account increased vapor-air mixturedensitiesandvaporgroMhratesas@mparedtoCategoryl€rgoes.
