COURSE INTRODUCTION
Many workplaces contain spaces that are considered to be "confined" because their configurations hinder the activities of employees who must enter into, work in or exit from them. In many instances, employees who work in confined spaces also face increased risk of exposure to serious physical injury from hazards such as entrapment, engulfment and hazardous atmospheric conditions. Confinement itself may pose entrapment hazards and work in confined spaces may keep employees closer to hazards such as machinery components than they would be otherwise. For example, confinement, limited access and restricted airflow can result in hazardous conditions that would not normally arise in an open workplace.
According to the Z117 ANSI Accredited Standards Committee (ASC) for Confined Spaces, a review of 200 confined space fatality cases from the U.S. Department of Labor (DOL) Occupational Safety and Health Administration (OSHA) database occurring between 1993 and 2004 confirmed that the distribution of causes had not changed to any significant degree. The committee also noted that approximately 65 percent of incidents with fatalities involved atmospheric contamination and engulfment accounted for less than 10 percent of the identified causes.
