These guidelines are designed to help avoid the need for remediation of mold growth by taking quick action before growth starts. If mold growth is found on the materials listed in Table 1, refer to Table 2 for guidance on remediation. Depending on the size of the area involved and resources available, professional assistance may be needed to dry an area quickly and thoroughly. Table 1: Water Damage - Cleanup and Mold Prevention Guidelines for Response to Clean Water Damage within 24-48 Hours to Prevent Mold Growth* † Water-Damaged Material Actions • • For non-valuable items, discard books and Books and papers papers. • • Photocopy valuable/important items, discard originals. • · Freeze (in frost-free freezer or meat locker) or freeze-dry. § Carpet and backing - dry within 24-48 hours • • Remove water with water extraction vacuum. • • Reduce ambient humidity levels with dehumidifier. • · Accelerate drying process with fans. Ceiling tiles • · Discard and replace. Cellulose insulation • · Discard and replace. Concrete or cinder block surfaces • • Remove water with water extraction vacuum. • · Accelerate drying process with dehumidifiers, fans, and/or heaters. Fiberglass insulation • · Discard and replace. § Hard surface, porous flooring (Linoleum, • • Vacuum or damp wipe with water and mild ceramic tile, vinyl) detergent and allow to dry; scrub if necessary. • · Check to make sure underflooring is dry; dry underflooring if necessary. Non-porous, hard surfaces • · Vacuum or damp wipe with water and mild (Plastics, metals) detergent and allow to dry; scrub if necessary. Upholstered furniture • • Remove water with water extraction vacuum. • • Accelerate drying process with dehumidifiers, fans, and/or heaters. • · May be difficult to completely dry within 48 hours. If the piece is valuable, you may wish to consult a restoration/water damage professional who specializes in furniture. Wallboard • • May be dried in place if there is no obvious (Drywall and gypsum board) swelling and the seams are intact. If not, remove, discard, and replace. • · Ventilate the wall cavity, if possible. Window drapes • · Follow laundering or cleaning instructions recommended by the manufacturer. Wood surfaces • • Remove moisture immediately and use dehumidifiers, gentle heat, and fans for drying. (Use caution when applying heat to hardwood floors.) • • Treated or finished wood surfaces may be cleaned with mild detergent and clean water and allowed to dry. • · Wet paneling should be pried away from wall for drying. *If mold growth has occurred or materials have been wet for more than 48 hours, consult Table 2 guidelines. Even if materials are dried within 48 hours, mold growth may have occurred. Items may be tested by professionals if there is doubt. Note that mold growth will not always occur after 48 hours; this is only a guideline. Please note that Tables 1 and 2 contain general guidelines. Their purpose is to provide basic information for remediation managers to first assess the extent of the damage and then to determine whether the remediation should be managed by in-house personnel or outside professionals. The remediation manager can then use the guidelines to help design a remediation plan or to assess a plan submitted by outside professionals. †If a particular item(s) has high monetary or sentimental value, you may wish to consult a restoration/water damage specialist. §The subfloor under the carpet or other flooring material must also be cleaned and dried. See the appropriate section of this table for recommended actions depending on the composition of the subfloor. Source: USEPA, Mold Remediation in Schools and Commercial Buildings.

Tab 2 QUICKTM CARD Mold Molds are microscopic organisms found everywhere in the environment, indoors and outdoors. When present in large quantities, molds have the potential to cause adverse health effects. Health Effects of Mold Exposure • Sneezing • Cough and congestion • Runny nose • Aggravation of asthma • Eye irritation • Dermatitis (skin rash) People at Greatest Risk of Health Effects • Individuals with allergies, asthma, sinusitis, or other lung diseases. • Individuals with a weakened immune system (e.g., HIV patients). How to Recognize Mold • Sight – Usually appear as colored woolly mats. • Smell – Often produce a foul, musty, earthy smell. Preventing Mold Growth • Remove excess moisture with a wet-dry vacuum and dry out the building as quickly as possible. • Use fans to assist in the drying process. • Clean wet materials and surfaces with detergent and water. • Discard all water damaged materials. • Discard all porous materials that have been wet for more than 48 hours. General Mold Cleanup Tips • Identify and correct moisture problem. • Make sure working area is well ventilated. • Discard mold damaged materials in plastic bags. • Clean wet items and surfaces with detergent and water. • Disinfect cleaned surfaces with 1/4 to 11/2 cup house- hold bleach in 1 gallon of water. CAUTION: Do not mix bleach with other cleaning products that con- tain ammonia. • Use respiratory protection. A N-95 respirator is rec- ommended. • Use hand and eye protection.

  • Hvac System Covid Procedures
    HVAC SYSTEM COVID PROCEDURES August 17, 2020 Prepared by: Johnson Roberts Associates 15 Properzi Way Somerville, MA 02143 Prepared for: City of Cambridge Executive Summary The HVAC COVID procedures are a compilation of Industry Standards and CDC recommendations. However, it should be noted that good PPE (personal protective equipment), social distancing, hand washing/hygiene, and surface cleaning and disinfection strategies should be performed with HVAC system measures, as studies have shown that diseases are easily transmitted via direct person to person contact, contact from inanimate objects (e.g. room furniture, door and door knob surfaces) and through hand to mucous membrane (e.g. those in nose, mouth and eyes) contact than through aerosol transmission via a building’s HVAC system. Prior to re-occupying buildings, it is recommended that existing building HVAC systems are evaluated to ensure the HVAC system is in proper working order and to determine if the existing system or its associated control operation can be modified as part of a HVAC system mitigation strategy. Any identified deficiencies should be repaired and corrected, and if the building HVAC system is a good candidate for modifications those measures should be implemented. In general HVAC system mitigation strategies should include the following recommendations: 1. Increase Outdoor Air. The OA increase must be within Unit's capacity in order to provide adequate heating or cooling so Thermal Comfort is not negatively impacted. Also use caution when increasing OA in polluted areas (e.g. High Traffic/City areas) and during times of high pollen counts. 2. Disable Demand Control Ventilation where present.

Although some taxonomic confusion in the family has been clarifed, rDNA data alone is unable to resolve higher level phylogenetic relationships within Mortierellaceae. In this study, we applied two parallel approaches to resolve the Mortierel- laceae phylogeny: low coverage genome (LCG) sequencing and high-throughput, multiplexed targeted amplicon sequenc- ing to generate sequence data for multi-gene phylogenetics. We then combined our datasets to provide a well-supported genome-based phylogeny having broad sampling depth from the amplicon dataset. Resolving the Mortierellaceae phylogeny into monophyletic genera resulted in 13 genera, 7 of which are newly proposed. Low-coverage genome sequencing proved to be a relatively cost-efective means of generating a high-confdence phylogeny.

    ARTICLE https://doi.org/10.1038/s41467-021-25308-w OPEN Phylogenomics of a new fungal phylum reveals multiple waves of reductive evolution across Holomycota ✉ ✉ Luis Javier Galindo 1 , Purificación López-García 1, Guifré Torruella1, Sergey Karpov2,3 & David Moreira 1 Compared to multicellular fungi and unicellular yeasts, unicellular fungi with free-living fla- gellated stages (zoospores) remain poorly known and their phylogenetic position is often 1234567890():,; unresolved. Recently, rRNA gene phylogenetic analyses of two atypical parasitic fungi with amoeboid zoospores and long kinetosomes, the sanchytrids Amoeboradix gromovi and San- chytrium tribonematis, showed that they formed a monophyletic group without close affinity with known fungal clades. Here, we sequence single-cell genomes for both species to assess their phylogenetic position and evolution. Phylogenomic analyses using different protein datasets and a comprehensive taxon sampling result in an almost fully-resolved fungal tree, with Chytridiomycota as sister to all other fungi, and sanchytrids forming a well-supported, fast-evolving clade sister to Blastocladiomycota. Comparative genomic analyses across fungi and their allies (Holomycota) reveal an atypically reduced metabolic repertoire for sanchy- trids. We infer three main independent flagellum losses from the distribution of over 60 flagellum-specific proteins across Holomycota. Based on sanchytrids’ phylogenetic position and unique traits, we propose the designation of a novel phylum, Sanchytriomycota. In addition, our results indicate that most of the hyphal morphogenesis gene repertoire of multicellular fungi had already evolved in early holomycotan lineages. 1 Ecologie Systématique Evolution, CNRS, Université Paris-Saclay, AgroParisTech, Orsay, France. 2 Zoological Institute, Russian Academy of Sciences, St. ✉ Petersburg, Russia. 3 St.
