Industrial Hygiene

CTSI industrial hygienists provide a wide array of services aimed at evaluating potential environmental hazards. Our hygienists have assessed thousands of workplaces, decreased health risks, and provided solutions to mitigate future environmental incidents.

Our exceptional team members will analyze, design, develop, implement and evaluate organizational safety management processes and tailor training based on the client’s assessed needs.

Indoor Environmental Quality (IEQ) / Indoor Air Quality (IAQ)

CTSI has been deployed to manage thousands of indoor environmental quality projects for varying-sized companies. Our trained professionals can provide a full range of indoor environmental investigations, monitoring to determine adherence to established comfort and ventilation parameters and environmental quality guidelines.

Nosocomial, symptom, or odor-related investigations are performed to evaluate occupant complaints/symptoms for potential building or site-related sources. CTSI‘s approach considers all potential sources, including biological, chemical, ergonomic, physical and psychological factors.

Symptom-based investigations identify the potential source(s) of symptoms, which may include allergic reactions, decreased productivity, or infections.

Inspections can include building-related issues, such as HVAC function, water conservation, potential contaminant sources, and conditions conducive to the development of microbial growth.

Evaluations can include any airborne/water contaminant or parameter: Microbial, temperature, relative humidity, dew point, particulates, gases, vapors, chemical agents, etc.

Asbestos, Lead, Mold

Asbestos Containing Material (ACM) Testing & Monitoring Services

CTSI‘s approach is to investigate, understand the client’s needs, and provide recommendations. CTSI has performed thousands of asbestos related projects in over 100 million square feet with its qualified personnel with a combined experience of more than 100 years. All of our projects have been completed within budget, and have complied with all state and local rules and regulations.

Microbial (Mold & Bacteria) Investigation and Preventive Investigations

Microbial Investigations and Assessments

Microbial (mold and bacteria) contamination and remediation surveys are performed to determine the presence and levels of microbes within a space. Most microbial issues are moisture-related: roof, window, wall and foundation leaks, condensation control deficiencies, reversed or compromised vapor barriers, and HVAC insulation deficiencies are among the many potential sources of moisture.
Some microbial issues are vector-based (cross-contamination) and may be affected by the following: traffic patterns, donning/doffing, ingress/egress, patient-handling procedures, filter change procedures, disinfection procedures and food-handling procedures. Non-human transmission routes can include airflow patterns, manufacturer supply quality, storage deficiencies, and rodent or arthropods infestation. Sampling can involve air, water, soil, materials, HVAC components, and other materials.

Mold Operation & Maintenance (MOM) Programs

MOM programs are the combination of policies and building management systems aimed at proactively maintaining the building integrity and mechanical systems in place.
MOM programs have been designed to detect and eliminate water intrusion or uncontrolled moisture accumulation to help prevent mold growth.

MOM Program Components

Policy and program management
Property assessment and building inspection plan
HVAC operation and maintenance plan
Indoor environmental quality plan and periodic monitoring program
Water intrusion emergency response plan
Water intrusion detection and prevention plan
Microbial clean up and remediation plan
Construction management and control guidelines
Occupant, employee, and contractor training program
Communication, documentation, and record keeping

Hazardous Material Testing

Air Sampling: Analysis & Evaluation

To determine the constituents of concern in water (pool, ponds, lakes, marine, benthic, potable, sewerage, runoff, stream, river, tank, monitoring well, groundwater, or other specified water systems), sampling and analysis are readily available. Analysis includes detection and/or identification and quantification of all particles, fibers, chemicals, toxins, allergens, irritants, infectious agents, temperature, flow, concentration, gradient, turbidity, pH, BOD/COD, etc.

Water Sampling: Analysis & Evaluation

To determine the constituents of concern in water(pool, ponds, lakes, marine, benthic, potable, sewerage, runoff, stream, river, tank, monitoring well, groundwater, or other specified environments), sampling and analysis is available for potential parameters. Analysis includes dtection and/or identification and quantification of all particles, fibers, chemicals, toxins, allergens, irritants, infectious agents, temperature, flow, concentration, gradient, turbidty, pH, BOD/COD, etc.

Soil Sampling: Analysis & Evaluation

Sampling and analysis are available to determine the constituents of concern in soil. Analysis includes detection and/or identification and quantification or particles, fibers, chemicals, toxins, allergens, irritants, infectious agents, grain, permeability, concentration gradient, pH, etc.

Materials Sampling: Analysis & Evaluation

CTSI conducts materials sampling, analysis, and evaluation to evaluate hazardous materials. Evaluations can include health and safety or structural parameters. Material sampling can be performed on asbestos, lead, concrete, steel, glass, cement, wood, plastic, and soil. The evaluation can determine the type and/or composition of the material(s), as well as its properties (strength, flame resistance, freeze/thaw resistance, and others). Compliance and sampling abide by American Society for Testing and Materials (ASTM), EPA, and other relevant organizations.

Water Management

CTSI is recognized as a leader in conducting water quality and Legionella investigations, as well, as providing property owners and building managers with expert advice to help mitigate the overall crisis and long-term risk management of potable and non-potable water systems.

CTSI’s water programs and plans comply with the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the American National Standards Institute (ANSI) Standard 188-2015, and other applicable city and state guidelines. Building owners and managers must ensure that they have met their specific city and state requirements on managing Legionella in their systems. By procuring the help of an independent experienced water treatment consultant, your facility can increase reliability and extend the life of your critical systems.

CTSI assists in the mitigation of the risk of Legionella in your building the following ways:

Development of site-specific compliance plan

Full building or facility water analysis

Document management and record keeping

Water system inspections and quarterly reviews to confirm that all procedures are implemented

Development of risk mitigation plans and strategies

Support for in-house monitoring to ensure that all deficiencies are addressed promptly
