## Narrative

An employee was drilling and installing a pipe into a large concrete digester when the flare went out, creating additional pressure in the digester. The pressurized digester gas shot through the short section of 6-inch pipe, knocking the employee 5 feet off a scaffold to the concrete floor. The employee was exposed to hydrogen sulfide, stopped breathing, required CPR, and suffered a shoulder injury.
