Asbestos and Lead-Based Paint Services
ECS performs a variety of industrial hygiene services to identify the presence and location of asbestos (ACM) and lead-based paint (LBP). ECS can perform indoor air quality and industrial hygiene monitoring, as well as testing to determine solutions to indoor contaminant levels. ECS can prepare plans and specifications for removal projects, conduct pre-bid meetings, assist with contractor selection, prepare operations and maintenance programs and perform air monitoring during and post-ACM and LBP removal.
Mold is type of fungi without chlorophyll that reproduces by spores and lives by absorbing nutrients from organic matter. It lives in the soil, on plants, and on dead or decaying matter. Mold produces spores to reproduce, which then settle on surfaces. As surfaces begin to dry, these spores release mycotoxins. When ingested or inhaled, the spores may cause allergic reactions, including flu-like symptoms – itchy, watery eyes, coughing, bronchial and nasal passage irritation and inflammation, runny nose and sneezing. One of the most difficult challenges in properly handling mold is that once mold is present, dispersion can easily occur into unaffected areas, such as into and through HVAC systems. Cross contamination occurs as mold spores move from the initial area of contamination via HVAC systems through the air, possibly reaching interior spaces throughout the entire building.
Mold will not be present without adequate moisture; therefore, as part of any sampling program, identification of the moisture source is key. Before any mold problem can be corrected, these moisture sources need to be identified and corrected. Mitigation is the correction/restoration of conditions within the first 24 - 48 hours of a moisture release. These measures can include water extraction, material removal, dehumidification and use of fans to completely dry the area. Proactive steps are necessary to reduce the potential for mold growth, as several molds will begin to grow within 24 - 48 hours of a water release event (i.e. Aspergillus sp.). These procedures should be performed by certified/accredited personnel. ECS’ building envelope specialists can assist with the diagnosis and corrective measures needed to address mold issues within buildings. As needed, our staff of industrial hygienists can also perform sampling (air, surface, bulk, vacuum) to help determine the presence, type and quantity of fungal spores in the environment. Using this data, ECS staff can prepare remediation guidelines to address building contamination.
Mold Remediation is the identification and correction of the conditions that caused mold growth and the safe removal of mold-impacted materials. Remediation is the appropriate course of action when visible mold and/or elevated spore levels are present in the air. Remedial activities should be performed by trained and accredited personnel. Accredited personnel can safely remove mold from the indoor environment without causing harm to building workers or occupants.
The final step in resolving a mold concern is post-remediation testing, in which an industrial hygienist returns to the environment to perform visual observations in an effort to evaluate if the remediated areas are dry, visibly clean and free of debris and that all repairs have been completed. As needed these personnel will take additional surface/air samples 24 - 48 hours after remedial activities are concluded. Residual air concentrations will be checked against background outdoor concentrations and testing will be performed to determine whether all materials register at normal moisture levels prior to build back activities. The environmental team will then document the remedial efforts performed, as well as the effectiveness of the final results.
