Ensure a safe indoor environment
Indoor air quality (IAQ) in healthcare facilities is unique for multiple reasons: 1) presence of microbes, viruses and bacteria associated with illness can lead to serious infections and disease; 2) controlling ventilation systems, including temperature, humidity and air change; and 3) volume and diversity of people-visitors, patients, employees, medical staff, and contractors going in and out of the building every day.
The Sigma Group employs engineering and industrial hygiene principles to scientifically collect, analyze and report IAQ data to assist healthcare clients to make sound, informed decisions. Sigma develops appropriate risk-based monitoring strategies to ensure a safe environment for building occupants. Sigma provides rapid responses and concise reporting of findings tailored to situation-driven needs.
Avoid sick building syndrome
A poorly maintained or operated building can result in occupants complaining about IAQ-related problems. Sigma performs visual walk-through inspections of area cleanliness and building condition to determine potential sources of airborne pollutants and identify possible corrective actions.
Renovation and demolition
Construction, renovation and demolition projects can present situations that may release contaminants that can impact the IAQ of a facility. These contaminants may be transported to other areas via heating, ventilation and air conditioning systems and subsequently affect occupants beyond the immediate project area. Sigma provides air quality monitoring of airborne biological and particulate matter, asbestos fiber, temperature, and relative humidity before, during and after such activities. Services include participation in the infection control risk assessment (ICRA) process, providing dust management control recommendations, and evaluating dust containment barrier construction and effectiveness.
Sigma minimizes liability risks by using state-of-the-art inspection and assessment techniques for moisture and mold-related problems. Services include air and material sampling and evaluation, water intrusion mitigation planning, and mold abatement observation and clearance monitoring. Air quality and building material assessments for biological agents involve:
- Bacterial and fungal (mold) organisms
- Microbial volatile organic compounds (VOCs)
Evaluating occupant exposure
Sigma provides patient, employee, contractor and visitor exposure evaluations for airborne contaminants (see below). Sigma makes recommendations to obtain or remain in compliance with OSHA, ACGIH, and NIOSH employee exposure limits or guidelines.
