Part One of the series, "Understanding Confined Spaces," defines confined spaces and tells where they are likely to be found. The program discusses the hazards associated with a confined space, including flammable and explosive atmospheres, oxygen deficient and oxygen enriched atmospheres, toxic atmospheres and physical hazards. It studies the difference between non-permit and permit spaces and explains the elements of a confined space permit. Other topics covered include developing an entry plan; responsibilities of the entry supervisor, the entrant and the attendant; blinding and blanking; lockout/tagout; atmospheric testing; ventilation; and protective clothing. (26 min.)
It is estimated that 3 million workers enter confined spaces each year for the purpose of maintenance, repairs, installations, inspections and meter reading. Unfortunately, unless proper precautions are taken, confined spaces can pose a number of significant hazards, including toxic atmospheres, electrical hazards, mechanical dangers, fire, heat exhaustion - the list is long. There are thousands of incidents on record in which either confined space workers, wouldbe rescuers, or both have been overcome. OSHA now requires training for workers who must enter confined spaces, and has set up standards which aim to eliminate the dangers posed by confined spaces.
