(MOBILE, Ala.) – Millard was back in business Tuesday with cars in the parking lot and workers on site, but the problems persisted from Monday’s leak as more people continued to pour into local hospitals.

Zizedeka Reed says her husband is in intensive care at Infirmary West.

“He has ammonia actually in his lungs right now and they got to monitor that,” Reed said.

More people who didn’t go to the hospital Monday went Tuesday. Outside the University of South Alabama Medical center, Jimmy Harrison, who works at the oil decontamination site said he still had a headache the next day.

“That’s why I came down here today because I figured that it would be gone, but it’s not,” Jon Tracy, who also works at the decontamination site, said. “There’s a lot, about 20 people in there today. Just about everybody in the emergency room today, that’s why they’re here.”

As on Tuesday morning, there were also 20 patients were still at USA Medical Center.

“My son had a motorcycle accident and they said he’s been down there for about 13 hours because they were full from the accident with the ammonia,” Traci Hale said.

OSHA is investigating how many people are impacted and how the leak happened. It’s not the first investigation at this Theodore plant. In 2007, OSHA fined Millard for serious violations which included not making the procedure for handling hazardous materials accessible to employees.

“It’s to ensure that employees understand what they’re dealing with and what they need to do in the event that something catastrophic occurs,” Kurt Petermeyer with OSHA said.
