Acid Spill Closes I-5 Off-Ramp in Carlsbad

Pool acid spilled in Carlsbad has closed an off-ramp from Interstate 5, according to the California Highway Patrol.

Three to four containers of pool acid were spilled at the off-ramp from southbound I-5 to Poinsettia Lane just before 8 a.m., CHP officers said.

The chemical has a tendency to create visible smoke and can be hazardous if someone is too close, Carlsbad firefighters said.

Hazardous materials experts closed the road to neutralize the chemicals and nearby residents were advised to stay indoors until the cleanup was complete, firefighters said.
