S500 (Water) // S520 (Mold) // NY City Guidelines In general, which remediation guidelines/standards should a remediator be familiar with? S520 Standard for Professional Mold Remediation The industry standard of care document for mold remediation contractors is...? Condition 1 // Normal or uncontaminated building or items // Indoor environment that may have settled spores, fungal fragments whose identity; location and quantity are reflective of a normal fungal ecology for a similar indoor environment // no treatment necessary What does "normal fungal ecology" mean? Indoor environment which is primarily contaminated with settled spores that were dispersed directly or indirectly from a condition 3 area // Spores landed on indoor surfaces or are suspended in the air but are not actively growing // HEPA vacuuming or damp wiping Describe a Condition 2 Indoor environment contaminated with the presence of actual mold growth and associated spores // Actual growth includes growth that is active or dormant, visible or hidden Describe a Condition 3 Yes Do you find settled spores in indoor environments with no complaints? CONDITION 2 (SETTLED SPORES HAVE AN UNUSUAL DISTRIBUTION) What are "settled spores" according to the S520? Should The Trigger language term that defines the "standard of care" in the S500 and S520 is...? Shall The Trigger language term that defines mandatory or regulatory requirements (S500 & S520) is? recommended The trigger language term that defines advised or suggested (S500 & S520) is...? Complexities How are situations referred to in the S500 and S520 that make a project more difficult or detailed, but the project can still be performed? Complications How are situations referred to in the S500 and S520 that make a project more intricate or complex after the start, but the project can still be performed with a change in scope? Limitations How are situations referred to in the S500 and S520 that limit the scope and remediation activities? No Are there federal mold remediation regulations in the US or Canada? Workers health, other occupants, unaffected area, HVAC system What are we trying to protect in a microbial remediation project? Identify and eliminate the water source What should be the first step in a microbial remediation project? Ability of people to reocc What is the ultimate cleaning criterion (according to the ACGIH Bioaerosols) Methods and procedures that we implement to protect the worker & occupants & HVAC system What does engineering control mean? Isolation with Containment, Airflow Management, HEPA filtration and controlled demolition methods Name Engineering Controls PPE What is not an engineering control? One millionth of a meter What is the definition of a micron? DIGITAL MONOMETER How can evaluate and test an air flow and a pressure differential? High Efficiency Particulate Air What does the acronym HEPA stand for? removes 99.97% of particulate matter of 0.3 microns and larger WHAT IS THE DEFINITION OF HEPA FILTRATION? Isolation of work area, managing air flow and controlled demolition What are the three main principles used for protecting people and unaffected environments? Preloss conditions // safe & sanitary // Condition 1 - normal fungal ecology What are the goals in a microbial remediation project for the remediator and IEP (Indoor Environmental Professional)? Water source What factors are necessary for mold growth to occur? Keep building dry and when wet, dry immediately and expediently What is the best way to prevent mold growth in a building? Wet building materials What can create odors in wet buildings? When air is supplied to a space than taken out Define positive pressure in a space? When air is taken out of the space Define negative pressure in a space? Enclosure in a work area that is contained with poly What is a local containment? Effectiveness of our hepa filters What can laser particle counters be used for? High to low Airflow always move from a ____ to a ___ pressure? TRUE Particles that are smaller than 5 microns can be inhaled deeply into the lungs. True or False Organism is water loving What does the term hydrophilic mean? Organism avoids water What'd does hydrophobic mean? Cat 1 - clean - low infection risk / Cat 2 - gray - medium infection risk / Cat 3 - black - large infection risk Name the Categories of Water according to the S500 All 3 categories With which Category of Water can microbial growth occur? Toilet Bowl = 2 // Surface Water from Raising Rivers = 3 // Hydrostatic seepage = 2 // Aquarium =2 // Water beyond the trap=3 // Broken toilet tank=1 // Sea Water=3 // Dishwasher and laundry & washing machine=2// Water in toilet bowl=1 What categories of water (S500) do these sources fall under? Toilet Bowl? Surface Water from Raising Rivers? Hydrostatic seepage? Aquarium? Water beyond the trap? Broken toilet tank? Sea Water? Dishwasher and laundry/washing machine? Water in toilet bowl? Above 17% What % of moisture content (meter reading) is necessary for mold growth to occur on wood? Above 20% Wood rot can occur at which percent of moisture content? the amount of free water available on the boundary layer of a substrate (surface) for microbial amplication What is the definition of water activity (aw)? Equilibrium Relative Humidity (ERH) What moisture measurement is comparable to water activity (aw)? identification / correction of moisture problem // isolation of work area and HVAC registers // air flow management (negative air) // demolition and removal of porous materials // cleaning of remaining materials // deep cleaning of all surfaces in work area // post remediation "clearance" testing // reconstruction What is the sequence (order) of procedures in a
