As Buffalo Biodiesel continues to innovate and expand its footprint across Western New York, the company recently undertook significant plant upgrades. Large-scale tanks were retrofitted, necessitating extensive flat and vertical concrete work to support the expanding infrastructure. However, what should have been a routine construction milestone revealed an alarming industry standard.
During the concrete pouring process, workers were observed spraying the concrete forms with heavy, hydrocarbon-based release agents. These chemicals, essential for preventing concrete from sticking to wooden or metal molds, filled the air with strong, noxious fumes. Short-term exposure to these fumes can cause eye, nose, and throat irritation, headaches, and nausea. Prolonged exposure has been linked to severe central nervous system damage and organ failure. Furthermore, conventional form release agents are highly flammable, creating severe fire hazards on active jobsites where welding or grinding frequently occurs.
Beyond human health, these chemicals pose an environmental threat. Traditional form release agents often drip or wash off forms into the surrounding soil. The heavy petroleum distillates contaminate groundwater, poison local ecology, and leave lasting toxic footprints long after the concrete has cured.
The Invisible Threat: Understanding VOCS
To understand why spraying heavy hydrocarbons on concrete forms is problematic, one must first understand Volatile Organic Compounds (VOCs). VOCs are a large group of carbon-based chemicals that easily evaporate at room temperature. While this rapid evaporation is exactly what allows solvent-based paints and form releases to dry quickly, it is a disaster for air quality and human health…
