A British archeological sponsor - Lord Carnarvon after attending the tombs opening died shortly afterwards inspiring supernatural “curse” speculation. • In recent years a scientific mummy's-curse theory was offered for Carnarvon's death. Was he killed by exposure to ancient, toxic pathogens from the sealed tomb? • Some ancient mummies do carry mold, including at least two potentially dangerous species—Aspergillus niger and Aspergillus flavus. • Some tomb walls may also be covered with respiratory- assaulting bacteria like Pseudomonas and Staphylococcus. • Bats inhabit many excavated tombs, and their droppings carry a fungus that can cause the influenza-like respiratory disease histoplasmosis. Under the right conditions such hazards could prove deadly. 66
- 62. Recommendations…. • If you suspect mold or mildew; or detect an unpleasant “musty” odor, there is usually excessive moisture, humidity or water present. Test the area. • Discovering the cause of, and remediating the source of the excessive moisture is essential to prevent a reoccurrence of mold. • Properly using the correct types of PPE is essential to safeguard your health. When in doubt, always proceed on the side of caution by making possibly dangerous situations non-issues. • Have resources “In Place” in Advance of a potential need. Conversely, developing a plan and searching for resources while under duress is far more stressful strategy that typically results in higher costs and longer recovery times. 67

Editor's Notes
- Share Ideas and Strategies to increase your Efficiency & Effectiveness Harms Way mean, protect you,personalybb, your team and building occupants health & out of the News Headlines in a Bad way.
- Mold is far more Highly Structured and organized then most people realize. it can be a Very Powerful & Resilient Adversary. Some mold has bio films that are provide strong protection for chemicals and other threats the mold faces. Some molds “Hide” underneath other molds for concealment purposes as a Defense Mechanism.
- Generally, an “Outside” sample is always taken as a “Control” sample that is compared with samples taken within the building envelope. It is critical to get “Good Clean Sampling Data”, then it is equally important to be able to interpret the data correctly. Critical to have the lab do good analysis of the samples.
- Gift Card. Because during the remediation process indoor air quality can degrade drastically and mold spore counts can rapidly increase. Containment areas are typically under air negative air pressure and being vented thru HEPA air scrubber to the outside of the building.
- Some Lawyers refer to Mold as Gold and they Train Hard to get their Gold. I’d prefer that it not be mine. Pass the 2 books around class.
- Lets talk about ENHANCING OUR CREDITABILITY: The number 1 question about mold that is rarely asked directly is: 1. DO YOU CARE? & 2.ARE YOU QUALIFIED TO HANDEL THIS PROBLEM? Do you Care? Ask Questions even if you know the answers; it demonstrates care & concern. The person who is the initial point of contact CAN BE very important IT sets the Tone for the entire project. The 1st point of contact onsite should be Well Qualified to communicate credibly with concerned parties.
- compounds, they can come from other sources. Such as Organic Mattermmmgrowing mold produces a wide range of volatile compounds, some of which can carry a musty odor, even in Low Concentrations. Mold colonies do not have to be sporulating to release these VOC compounds, so that nearly invisible mold can be the source; in another words: The mold does not have to be releasing mold spores in order for bad smells to occur. Common Sources of musty odors are: Carpeting & Pad; Concrete; Very Old Wood or Paper products sometimes even in “Dry” environments. Musty Odors: Do They Always Indicate Mold? By Dr. Harriet Burge, EMLab P&K Chief Aerobiologist and Director of Scientific Advisory Board
- The vast majority of Fungi & Mold has not be studied. We know relatively little about Mold & Fungi. Many mold species have only I.D. numbers assigned to them, and have not been studied, and do not have a specific name assigned to the species of mold. The English word fungus is directly adopted from the Latin fungus (mushroom). This in turn is derived from the Greek word sphongos ("sponge"), which refers to the macroscopic structures and morphology of mushrooms and molds. The use of the word mycology, denote the scientific study of fungi is thought to have originated in 1836 with English naturalist Miles Joseph Berkeley.
- Ancient Written Instructions Concerning Mold: Written 1400 BC approximately . Leviticus 13: 36-40 No mention of “Black” mold; there are other Colors & Types of mold that are problematic to people. These instructions relate to houses only. There are other instructions regarding moldy fabrics as well in this manuscript.
- Gift card for correct answere
- The CMHC is equivalent to our FHA. It has some good information and is relatively unbiased. You can visit the CMHC web site for additional information.
- Mycotoxins can have a wide range of Adverse Human health effects. Where conditions are right, fungi proliferate into colonies and mycotoxin levels become high. The symptoms of a mycotoxicosis depend on the type of mycotoxin; the concentration and length of exposure; as well as age, health, and sex of the exposed individual. Mycotoxins have the potential for both acute and chronic health effects via ingestion, skin contact and inhalation. Some of the mycotoxins in the indoor environment that are more well known are: Alternaria, Aspergillus , Penicillium, and Stachybotrys others which are largely unstudied. The infestation of S. chartarum in buildings containing gypsum board, as well as on ceiling tiles, is very common and has recently become a more recognized problem.
- Pictures are taken thru an Electron Microscope of various fungi. Aspergillus fungus spores,
- Mold exposures have a variety of health effects depending on the person, some people are more sensitive to mold than others. Exposure to mold can cause a number of health issues such as; throat irritation, nasal stuffiness, eye irritation, cough and wheezing, as well as skin irritation in some cases. People at higher risk for mold allergies are people with chronic lung illnesses, which will result in more severe reactions when exposed to mold. Infants may develop respiratory symptoms as a result of exposure to a specific type of fungal mold, called Penicillium. Infants will begin to show respiratory problems if they have a persistent cough and/or wheeze. The number of days that a child will suffer from respiratory symptoms during their first year of life increases by an average of 20% every time the level of Pencicillium increases. The levels are deemed no mold to low level, from low to intermediate, from intermediate to high. [3]

- Tell of building in Florida where All the Electrical wiring had to be replaced Anyone who wants the study email me I will send it 2008.
- In 2008, a study of common cleaning products found the presence of carbon tetrachloride in "very high concentrations" (up to 101 mg m−3) as a result of manufacturers' mixing of surfactants or soap with sodium hypochlorite (bleach).[18] ^ Odabasi M (2008). "Halogenated Volatile Organic Compounds from the Use of Chlorine-Bleach-Containing Household Products". Environmental Science & Technology 42 (5): 1445–51. doi:10.1021/es702355u
- Air quality issues become amplified . For example: humidification problems can increase significantly when air exchanges decrease. Air Sampling & other types of testing are becoming more commonplace. The astronomical sizes of litigation awards draws increased levels of media coverage. and can diagnose problems that were previously unexplained. The media tends to dramatize certain types of events and Mold is one such event especially when large law suites are at stake.
- Assessment is done thru: Visual Inspections, Mold Sampling, Moisture Testing where data is collected sent to and tested at a laboratory. Remediation is the physical process of having workers: Remove or Decontaminate damaged building products.
- Use of the protective suite can raise personnel’s body temperatures significantly. Proper hydration is critical to worker’s safety. The boots which are attached to the suite can be extremely slippery on wet surfaces.
- Some gloves are available in latex free composition for personal with latex sensitivity. Gloves are generally available with or without powder depending on personal preference. The thickness chosen may depend on the type of work needed to be completed, i.e.. handling papers or doing demolition work. Note: that the glove pictured below has a much thicker fabric than the glove pictured above.
- Slipping on wet and damp surfaces is a real danger when wearing “Tyvek” type suites, especially on non porous surfaces.
- Having an exhalation valve helps improve breathing efficiency, by allowing air to be expelled “easier” than without a valve. If you are doing a job that is physically taxing have a exhalation valve is a good investment. Increased air flow resistance significantly taxes personal physically, and reduces worker productivity. Most of the N95’s sold today do not have the exhalation valves.
- These masks are relatively inexpensive and fairly durable. If “stand alone” eye protection is used the combined cost is generally half of that of a full face mask. Half face respirators offer the advantage of being able to utilize a wide range of replaceable filter cartridges in a variety of environments. The eye protection shown is “air tight”, and separate from the respirator; these types of eye protection tend to “fog” up with heavy usage. A disadvantage of the half face mask is that is does not provide any type of “built in” eye protection, and a limited amount of face protection.
- The respirator pictured at top does NOT have air filters attached. The respirator shown at bottom has both filters installed. There are hundreds of filters to choose from. Their tends to be less fogging of the mask area compared to individual goggle usage. OSHA regulations require that no facial hair be present such as beards; in order to have a secure seal around the face area.
- Filters have 9 different classes and 3 levels of efficiency the are rated at either 95, 99 or 99.97% Filter usage is indicated by the N, R and P designations. N-series filters are Not resistant to oil aerosols. R-series filters are "resistant to oil" and P-series filters should be selected if there are oil aerosols or non-oil aerosols in the workplace. All nine classes filter the same particle size (0.3 micrometers aerodynamic mass median diameter). “P” filters become more efficient at filtration of particles with use; however, breathing becomes more difficult due to increased air flow restriction due to particle build up on the filter media.
- Breathing is easier by utilizing positive air flow inside a full face mask. Power blowers allowing for increased worker productivity due to less breathing related fatigue. Power pack and blower mounts around workers waist on the belt pictured to wearer’s along their back. The equipment costs are considerably higher than other non powered filtration systems. After the initial equipment set up expenses, due to the constant “powered” air flow, filters generally have a shorter “life” expectancy thus there are additional filter expenses.
- It is not uncommon for one species of mold to grow on top of another species of mold, see what appears to be one species on top of another, look for the color variations in the pictures.
- HEPA stands for: High Efficiency Particulate Air. This is a specific type of filter media which traps particulate matter from the air as it passes thru the filter.
- During the remediation process airborne particulate particles typically increase; the use of HEPA vacuums to capture this particulate matter is a common protocol. Vacuuming in conjunction with physical agitation can be used as a preliminary step prior to the application of antimicrobial chemicals, due many species of fungi having a very thick bio film which resists antimicrobial liquids alone.
- An advantage of a “Portable” dehumidifier is that is can be placed exactly where it is needed, within the building envelope.
- and are generally placed outside the building. and may require a separate electrical power source
- Air sampling: the most common form of sampling to assess the level of mold. Sampling of the inside and outdoor air is conducted and the results to the level of mold spores inside the premises and outside are compared. Often, air sampling will provide positive identification of the existence of non-visible mold. Surface samples: sampling the amount of mold spores deposited on indoor surfaces (tape, swab and dust samples) Bulk samples: the removal of materials from the contaminated area to identify and determine the concentration of mold in the sample
- The bottom two pictures center and left are of air sampling systems of different vendors. Air is sucked into a cassette indicated by the red arrow and the particles impact various types of media and the particles impact speed of air is variable as is the length of time the air impacts the cassette.
- Advantages: A good method of identifying what types of mold are present. Disadvantages: It is not a good method to determine if the mold is currently “viable” (living or dormant)? This is not generally an issue because it is a good idea to get rid of the mold.
- Advantages: Can determine IF the mold is “viable” (alive). Disadvantages: Not the best method to determine what types (if any) of fungi are present or at what levels present (spore counts are not possible with this system).
- where as “Air Sampling” provides a “snapshot” of the current environmental conditions. There are different sampling methods for collection of dust sampling. Some use systems use specially designed vacuums that hold special collection cassettes. Other systems use vacuum pump systems and special dust collection media cassettes.
- There are times when you can get “cleaner” or more accurate examination results by “Bagging” & “Tagging” Bulk types of materials for lab analysis. It may be better to remove part of the suspected area itself and send it to a laboratory for direct microscopic examination.
- Patterns of mold growth are often indicators of the source of excessive moisture or a water intrusion. Top picture see above the doorway at the red arrow. Bottom picture see the darker color mold located closer to the floor.
- “Thermal fogging” utilizes heated liquids and generally creates smaller droplets or a “finer” size mist than compared to ULV fogging can be used to apply antimicrobial agents or odor control agents When liquids are heated the system is called “thermal fogging”; smaller droplets are created and better saturation can be achieved. Typically, this system is used for odor control agents. When liquids are applied with out heat typically the system is called “ULV fogging”; larger liquid droplets are formed and larger volumes of liquid can be applied. Typically, this system is used to apply antimicrobial agents.
- “Truck” mounted water extraction equipment is shown is these pictures. Removing the water and reducing the humidity to “normal” levels as quickly as possible is critical to mitigate additional damage and costs to a “water loss” situation. Failure to remove the excessive moisture may result in microbial issues developing.
- The defendants in this case (the hotel corporation) in April 2003 in turn sued nearly 20 architects, contractors and subcontractors involved in the design and construction of the hotel. The plaintiffs claimed the discovery of mold in the hotel was a material fact that should have been disclosed to the guests.
- The defendants prevailed in this case however they were able to produce a great deal of evidence to contradict the claims of the plaintiff.
- Pictures of “Stackie” Pets drinking mold infested surface water drainage can be at risk. A mycotoxin (from Greek μύκης (mykes, mukos) “fungus” and Latin (toxicum) “poison”. mycotoxin is a toxic secondary metabolite produced by organisms commonly known as molds. Exposure to high levels of mycotoxins can lead to neurological problems and in some cases death. Prolonged exposure, e.g., daily workplace exposure, can be particularly harmful . The term ‘mycotoxin’ is usually reserved for the toxic chemical products produced by fungi commonly known as mold. by Alternaria, Aspergillus (multiple forms), Penicillium, and Stachybotrys.[27] Stachybotrys chartarum contains a higher number of mycotoxins than other molds grown in the indoor environment and has been associated with allergies and respiratory inflammation.[28] The infestation of S. chartarum in
- Disadvantages of using Ozone include: Occupants and pets must be evacuated for the duration of the high levels of ozone. Ozone can also kill vermin. Ozone is a powerful oxidizing agent which could damage rubber and other certain building materials. Ozone in and of itself can leave a lingering odor of itself for a few days. Killing mold inside walls does not remove the mold, and that dead mold may continue to have adverse health effects on building inhabitants.
- There are many other potential symptoms that can be associated with mold exposure, the above list is not exhaustive.
- Give the persons with the correct answer a prize.
- At stronger concentrations you have a very different cocktail from doing laundry work. Noticed how the smell of bleach can sometimes become stronger in a laundry area as the wash cycle proceeds? Why, bleach (Sodium Hypochlorite ) as it is exposed to organic matter can to can create VOC’s which can be a strong odorant.
- What happens if your disinfectant does not have Surfactants? It does not penetrate into porous surfaces. You can “kill” mold at the surface and leave the mold root structure intact due to a lack of penetration. Cite past job site experiences where mold was growing on the walls within 72 hours.
- This study has been around long enough to withstand a barrage of criticism; to date only the conclusions with the statement “conclusions being hypothetical” have been added by main stream commentaries.
- You may experience a significant amount of stress & pressure during a Loss Type of Situation.
