CORONADO, Calif. - Four laborers and a police officer were sent to hospitals Friday after being overcome by chemical fumes at a residential construction site in Coronado.
The workers were applying a waterproofing sealant to the walls of a below-grade chamber on a parcel at Olive and G avenues when they began having respiratory problems shortly after 10 a.m., city Fire Chief Mike Blood said.
Medics administered oxygen to the crew members and a police officer who also reported some similar ill effects while responding to the emergency. The five men were then sent to medical centers for follow-up care. Their ailments were not believed to be serious, Blood said.
Police shut down the intersection as a precaution and sent for a hazardous materials team to determine if there were any lingering air-quality problems in the neighborhood.
By early afternoon, the area had been deemed safe and the streets were open again to through traffic.
