Any category of water Tools to measure air flows and pressure differentials -Smoke tube/pencil (air flows) -Digital manometer -Observation (bowling of plastic) -U tube manometer -Magnehelic gauges The 3 basic principles of remediation 1. Isolation of work area 2. Management of air flows 3. Controlled Demolition (low dust) Environmental Protection goals -Protect health and safety of workers -Protect unaffected environments -Protect occupants HEPA High-Efficiency Particulate Air or Arrestor HEPAs filter __% of particles 99.97% Thermophilic fungi Type of fungi that like higher temperatures Xerophilic Fungi Type of fungi that grows with little water or moisture. penicillium and aspergillus species What conditions do the specific fungi Cladospirium and Aureobasidium prefer to grow in? Condensate conditions What conditions do the specific fungi Penicillium and Aspergillus prefer to grow in? Damp conditions What conditions do the specific fungi Stachybotrys, Trichoderm, Rhizopus, and Fusarium prefer to grow in? Very wet conditions
