It happened at 139 E. Vance Street.
According to a Zebulon representative, someone was moving a package when hydrochloric acid spilled out of it. Eight people nearby felt nauseous and dizzy after the spill.
ABC11 was told it was pool cleaning supplies shipped from New Jersey. It is not out of the ordinary to have this substance shipped through the post office.
A Zebulon representative said fire EMS came to investigate the spill.
All affected by the substance were cleared and refused treatment.
The spill is being cleaned, and it will be clear soon, according to a Zebulon representative.
