Situation: An oriented-strand board manufacturer operated its plant on a 24-hour, 7-day work week with two 12-hours shifts. Shift changes occurred at 8:00 am and 8:00 pm. At approximately 8:30 pm on January 18, 2001, a wet hog, which was located in a wood room, dropped off line and would not operate. The wet hog was used to grind tree bark and wood residue into a wet fuel used in wet-fuel burners in the plant. The wet hog was not essential to the operation of the plant, and whether or not it was operating had no effect on other operations in the plant. An electrician was assigned to repair the hog. At approximately 10:30 pm, he entered the motor control room and opened a 2300-volt motor circuit breaker. He caused an electrical fault in the circuit breaker, apparently by contacting energized parts inside the circuit breaker cubicle, and the ensuing electric arc burned the employee and ignited his clothing. He sustained burns over 90 percent of his body, 60 percent of which were third-degree burns. Even thought he was badly burned, he departed the motor control center and walked approximately 43 meters to the first aid room. A nearby employee doused the remaining flames with water from a water cooler. Two emergency medical technicians who worked at the plant went to the first aid room and administered first aid to the injured employee. Emergency medical services arrived a few minutes later and transported the electrician to a hospital where he was admitted for treatment. The electrician died the next day at 12:11 pm. Make a root cause analysis and What actions could have been implemented to prevent this fatality?

The amount of dog food in each package should be 1 pound, and Yelp has determined that the standard deviation of the machine filling these packages is half an ounce, and the confidence interval is 14.85% (2= 1872). In order to confirm that the machine is operating properly, Yelp takes 16 sample bags every hour and weighs them.

- John Patrick has recently been hired as controller of Valdosta Vinyl Company (VVC), a manufacturer of vinyl siding used in residential construction. VVC has been in the vinyl siding business for many years and is currently investigating ways to modernize its manufacturing process. At the first staff meeting, Patrick attended, Jack Kielshesky, chief engineer, presented a proposal for automating the Molding Department. Kielshesky recommended that the company purchase two robots that would have the capability of replacing the eight direct-labor employees in the department. The cost savings outlined in the proposal include the elimination of direct-labor cost in the Molding Department plus a reduction of manufacturing overhead cost in the department to zero because VVC charges manufacturing overhead on the basis of direct-labor dollars using a plantwide rate. The president of VVC was puzzled by Kielshesky's explanation: "This just doesn't make any sense. How can a department's…arrow_forwardPrepare a run diagram for this emergency call data.
