A employee when troubleshooting a clogged HPLC had unplugged
it at various points to relieve pressure. The heat ex-changer outlet had been
unscrewed for a few seconds when the blockage dislodged and the pressurized
liquid shot into the employee's face. The employee was wearing all PPE but some
liquid dripped into the employee's eyes. The employee rinsed eyes in the eyewash
station and proceeded to employee health services for immediate first aid. Two days later the
employee’s symptoms worsened and required treatment beyond first aid.
