Indoor Air Quality on the jobsite

Indoor air quality is important on construction jobsites for several reasons. One, controlling dust and fumes supports productivity and the health of workers. Two, good air quality can protect duct work and reduce health risks to future occupants. Third, maintaining good conditions can help protect sensitive components and equipment from moisture and dust during and after installation.

Sources of poor IAQ include dust or particulate matter (PM) from combustion and materials like silica, fiberglass, asbestos, wood, and paving in and around the site. Harsh fumes from curing, painting, and finishes can compromise IAQ. Even moisture or unaddressed water leaks pose an issue because they can lead to mold growth and increased humidity, which can worsen indoor air quality (IAQ) by triggering respiratory problems, allergens, and the spread of harmful microorganisms.

How to manage IAQ?

1. Control and minimize sources and construct effective containments. Deploy temporary ventilation systems and HEPA filters that can automatically turn on when conditions demand it.
2. Monitor IAQ in and around the site using sensors and real-time alerts. Key indicators to track include particulate matter, VOCs, and excessive moisture and leaks:
   • Particulate matter (also referred to as PM or particle pollution) is a complex mixture of solid and/or liquid particles suspended in air. These particles vary in size, shape, and composition. The EPA issues an index to indicate potential health risks.
   • Volatile organic compounds (VOCs) are harmful chemicals that easily evaporate into the air from products like paints, adhesives, and cleaning supplies, contributing to indoor air pollution.
   • Excessive moisture and leaks lead to harmful mold and damage if left unchecked. Placing sensors in low-traffic, high-risk areas can minimize issues. Monitoring temporary water lines including use of flow stop valves can prevent undetected leaks from causing serious damage.

Ask your insurance broker about incentives for monitoring.  Insurance carriers are reducing deductibles or lowering premiums when sight monitoring is deployed.
