At 4:15 p.m. on December 6, 2021, a contractor, 26, removed transmitters from tanks to winterize the facilities. As the employee removed the bolts and loosened the transmitter from a tank, the contents (50% concentration of Sodium Hydroxide) sprayed out and onto the employee’s eyes, face, head, and chest (upper torso). The employee attempted to use a nearby emergency shower/eyewash, but it was shut down, and the employee then went to a nearby bathroom to rinse off the chemical.
