In the Field: Response to Hydrated Lime Spill on City Roadway
We have decades of experience with responding to incidents of varying impacts. Recently, we responded to a release of hydrated lime on a city roadway.Byline: BTB Editor
May 18, 2022 / Time to read: 5 minAfter a truck transporting hydrated lime experienced a spill on its delivery route, we were called in to clean up the affected area and help get the roadway back up and running as soon as safely possible.
The Challenge
A trailer valve malfunction caused approximately 1,000 gallons of product to spill onto a one and a half-mile stretch of public roadway in La Porte, TX. In large quantities, hydrated lime, a sodium bicarbonate solution, can be harmful to the ecosystem. When inhaled, it can also cause airway irritation in humans.
The Solution
Once on site, our Emergency Response Manager, Supervisor and technicians conducted a risk assessment and devised a plan of action using our STARRT Card (Safety Task and Risk Reduction Talk). This allowed the team to quickly identify hazards associated with the response and apply controls to perform the necessary cleanup tasks safely. Our team collaborated with the city fire department to set up traffic detours and block the impacted areas using high visibility road barriers, stop signs, cones and vehicles equipped with emergency traffic lighting systems. These efforts helped mitigate civilian traffic from driving through the affected area, as well as kept all personnel on site safe during the entirety of the cleanup response.
Our team of 18 professional crew members and technicians — outfitted with appropriate Personal Protection Equipment (PPE) — were quickly mobilized to the scene from our service center in Houston, TX. We applied absorbent boom to support drain system pollution control. Dikes were used to contain run-off and avoid leakage into nearby soil and water systems. Our technicians operated several industrial pressure washers to remediate the spill and followed up by pumping the contaminated wastewater into vacuum trucks for safe removal.
The Outcome
Our extensive knowledge and expertise, as well as our ability to quickly deploy needed resources, aided in the cleaning and remediation of the highway within 12 hours without any further incident. All associated waste was removed and securely transported to our facilities for treatment and safe disposal.
