PROJECT OVERVIEW:
Deploy proactive monitoring solutions for a construction project being performed in the St. Paul area. A 36- hour continuous concrete pour in close proximity to a community hospital was planned. The hospital had concerns about the effect gaseous emissions from the use of diesel equipment would have on air quality.
TECHNICAL HIGHLIGHTS:
A RAE Systems MultiRAE monitor equipped with toxic gas sensors and a photo ionization detector was deployed at a location between the active work area and hospital property. Sensors monitored combustible gas (LEL), oxygen, carbon monoxide and nitrous oxide as well as volatile organic compounds. Instruments were housed in a solar-powered, weather resistant solar-powered cellular gateway was deployed on-site to allow data to be transmitted in real time through a secure web interface. All stakeholders, including hospital and construction personnel were able to observe the field data without having to send individual representatives to the construction location.
KEY OUTCOMES:
Each stakeholder made his or her own determination that no potential exposures took place during the project. No interruptions to the construction project were necessary.
