Mold and Indoor Air Quality

Mold and Indoor Air Quality Services

The Blackledge Group offers years of experience providing mold and indoor air quality (IAQ) services for clients ranging small hotels to large commercial facilities. IAQ assessments are generally performed to evaluate occupant complaints or as part of a pro-active program.

We routinely investigate issues ranging from silica, odors, dust, odor, asbestos, mold, humidity, radon, and other contaminants that cause occupant safety concerns.

Our team includes qualified microbiologists and chemists to evaluate IAQ issues caused by microbiological materials such as molds, carbon dioxide, formaldehyde, temperature, humidity, carbon monoxide, radon gas, particulates and volatile organic compounds.

Rapid Response is Often Critical

In order to prevent small problems from becoming large problems, the ability to respond quickly is paramount. Our cross-disciplinary team of certified professionals provide rapid response in order to quickly assess the problem, develop a cost-effective plan, and oversee remediation activities.

The Process

Our approach to conducting Indoor Air Quality Investigations is simple and non-intrusive. After extensive interviewing of persons knowledgeable with the building’s history, we develop sampling protocol designed to provide the maximum amount of information for the lowest costs practical.

We collect air samples targeting the suspect contaminants and submit the samples to a third-party laboratory for analysis. Temperature, relative humidity and material moisture readings are also recorded. Where warranted, swab sampling, lift tape, spore traps or bulk sampling is performed.

Our experts can prepare Remediation Work Plans and Specifications to address means and methods to remove the microbial contamination and repair building systems. In addition, we perform post-remediation project monitor and clearance testing.

Effective IAQ control is accomplished through our inspection and testing process that includes the following:

  • Obtaining historical knowledge and evaluating locations in the facility of occupant complaints and health effects
  • Reviewing HVAC equipment and systems, filters, installation and use of exhaust systems (equipment, sewer, water systems, etc.)
  • Thoroughly reviewing water intrusion, moisture control, water damage, porous building materials and potential microbial growth concerns
  • Establishing a management approach to control water intrusion, moisture and reduce bio-aerosol and microbial growth

Silica

OSHA’s Respirable Crystalline Silica standard for general industry and maritime requires employers to limit worker exposures to respirable crystalline silica and to take other steps to protect workers. OSHA began enforcement of the Respirable Crystalline Silica standard for general industry and maritime on June 23, 2018. The Blackledge Group can help employers understand their responsibilities under OSHA’s Respirable Crystalline Silica standard and help you maintain OSHA compliance by:

  • Providing a baseline assessment of employee exposures to silica under various work condition
  • Determining appropriate PPE necessary to protect employees
  • Preparing Institutional and Engineering Controls to help limit workers’ access to areas where they could be exposed above the OSHA PEL
  • Setting up Respiratory Protection Programs and preparing Respiratory Protection Plans
  • Providing training programs designed to train workers on work operations that result in silica exposure and ways to limit exposure, and
  • Assisting with recordkeeping requirements, including exposure measurements, objective data, and medical exams.

 

Additionally, The Blackledge Group can assist engineering design firms and federal agencies develop appropriate specifications when preparing bid documents.
