For example, containment materials (5.3.1) <br />are shown as being either rigid or flexible. If the specifier requires the use of rigid materials only, this restriction <br />must be specified separately. <br />Note 3: Class 4W will capture dislodged paint chips and debris, but will not contain the water used for cleaning. <br />~ When vacuum shrouded waterjetting is employed, ground covers or free-hanging tarpaulins may provide controls <br />equivalent to Class 1 W. <br />TABLE P- POWER TOOL CLEANING* <br />COMBINATIONS OF CONTAINMENT AND VENTILATION SYSTEM COMPONENTS <br />4 of SSPC-Guide 6) <br />Ventilation (5 <br />Containment System <br />. <br />5.4.5 <br />Containment <br />5.3.1 <br />5.3.2 <br />5.3.3 <br />5.3.4 <br />5.3.5 <br />5.4,1 Air <br />5.4.2 <br />Input Air <br />5.4.3 - Air <br />5.4.4 <br />Air <br />Exhaust <br />Classification <br />Containment <br />penetrability <br />Support <br />Joints <br />Entryway <br />Make•Up <br />Flow <br />Pressure <br />Movement <br />Dust <br />Materials <br />Structure <br />Filtration <br />G1- <br />A1- Rigid <br />C1- Rigid <br />pl_ <br />F1 - <br />Forced <br />H2 -Visual <br />11- Minimum <br />J1- Air <br />Class 1 P <br />g~_ Air <br />Impenetrable <br />Cp _ <br />Full <br />E2 - <br />Controlled <br />G2 - <br />Verification <br />Specitied <br />Filtration <br />A2 Flexible <br />Flexible <br />Seal <br />Resealable <br />Natural <br />A1- Rigid <br />B1- Air <br />Impenetrable <br />C1- Rigid <br />p~ <br />E3 - <br />Overlap <br />G2 - <br />H3 • Not <br />12 - Not <br />J2 - Not <br />Class 2P <br />C2 <br />Full <br />F2 - Open <br />Natural <br />Required <br />Specified <br />Required <br />A2 Flexible <br />B2a or B2b - <br />Flexible <br />Seal <br />E4 - Open <br />Air Penetrable <br />Seam <br />A1- Rigid <br />82a or 132b - <br />C3 - <br />D2 <br />partial <br />E4 - 0Pen <br />F2 - Open <br />G2 - <br />H3 - Not <br />i <br />d <br />R <br />12 - Not <br />ecified <br />S <br />J2 - Not <br />Required I <br />Class 3P <br />Air Penetrable <br />Minimal <br />Seal <br />Seam <br />Natural <br />re <br />equ <br />p <br />A-2 Flexible <br />Note 1: When designing a ventila[ion system, care must be taken to balance the static pressure with the input air flow to avoid collapsing the <br />containment or ductwork due to high negative pressure. <br />Note 2: The table occasionally identities two options for a given component.
