A confined space is a space with limited entry and egress and not suitable for human inhabitants. An example is the interior of a storage tank, occasionally entered by maintenance workers but not intended for human occupancy. Hazards in a confined space often include harmful dust or gases, asphyxiation, submersion in liquids or free flowing granular solids for example, grain bins, electrocution, or entrapment.

Confined space accidents are of particular concern in occupational safety and health due to the hazards that they pose to the victim and subsequently to a rescue team. Confined space training outlines the skills and protocols for safe entry to confined spaces, and includes precautions such as locking and tagging out connecting piping, testing of breathable air quality, forced ventilation, observation of workers in the space, and a predetermined rescue plan with appropriate safety harnesses and other rescue equipment standing by. DescriptioneditAlthough the definition of a confined space varies between jurisdictions, it is generally recognized as a space that has limited or restricted means of entry or exit Enclose in natureis large enough for a person to enter to perform tasks is not designed or configured for continuous occupancy 2 andhas the potential for a significant hazard to be present. A utility tunnel, the inside of a boiler only accessible when the boiler is off, the inside of a fluid storage tank, a septic tank that has contained sewage, and a small underground electrical vault are all examples of confined spaces. Ships and other vessels commonly have confined spaces due to the need for compartmentalized watertight construction. The exact definition of a confined space varies depending on the type of industry. That is, confined spaces on a construction site are defined differently than confined spaces in a paper mill. Confined spaces that present special hazards to workers, including risks of toxic or asphyxiant gas accumulation, fires, falls, flooding, and entrapment may be classified as permit required confined spaces depending on the nature and severity of the hazard. Even normally habitable parts of a building such as corridors or offices may take on the characteristics of a confined space, during operations that alter normal ventilation and access. For example, a room may be wrapped in plastic sheeting for painting and any vapor emitted in the room may not be dispersed by blocked ventilation ducts. In the United States, entry into permit required confined spaces must comply with regulations promulgated by the Occupational Safety and Health Administration OSHA. These regulations include developing a written program, issuing entry permits, assigning attendants, designating entrants, and ensuring a means of rescue. According to the OSHA, a permit required confined space permit space has the three characteristics listed above which define a confined space and one or more of the following Contains or has the potential to contain a hazardous atmosphere. Contains a material that has the potential for engulfing the entrant. Has an internal configuration that might cause an entrant to be trapped or asphyxiated by inwardly converging walls or by a floor that slopes downward and tapers to a smaller cross section. Contains any other recognized serious safety or health hazards. In addition to the hazards posed by the design of the space, work activities can also pose serious safety hazards heat, noise, vapors, etc. Atmospheric hazardseditThe most common hazard seen in confined spaces is that of atmospheric hazards. These affect air quality and present immediate hazards to health or life. Acceptable atmospheric conditions must be verified before entry, and must be monitored continuously while the space is occupied. The oxygen concentration, the presence of toxic gases, and flammable material are the three conditions that must be monitored. Oxygen concentration is considered safe if it is between 1. To protect against toxic gases, contaminants have permissible exposure limits PELs, which are set by OSHA. Work also cannot continue if the concentration of a material reaches or exceeds 1. Even if a tank or similar vessel initially is tested and found to contain breathable air, a hazard can develop during operations inside the tank if residues inside the tank can release toxic gas or vapor when disturbed or if accidentally ignited. Steel water tanks may have dangerously low oxygen concentration when the interior rusts. Entry certificationeditIn many situations, certification of non hazardous atmosphere by a trained or competent person is required before personnel may enter a confined space without the use of a respirator. In the United States Navy, that person is the designated shipboard gas free engineer. Certification in civilian settings can be performed by an Entry Supervisor who, under OSHA regulations, is designated by the employer and ensures that the space is safe to enter and all hazards are controlled. In the United States, agricultural and construction operations are exempted from regulations governing permit required confined spaces which is specific to general industry, but they are still required to identify and control confined space hazards.

Injuries and fatalitieseditInjuries and fatalities involving confined spaces are frequent and often involve successive fatalities when would be rescuers succumb to the same problem as the initial victim. Approximately 6. 0 of fatalities involve would be rescuers and more than 3. One example was in 2. Sullivan Mine in British Columbia, Canada when one initial victim and then three rescuers all died. Accidents in confined spaces present unique challenges and are often catastrophic, such as the Xcel Energy Cabin Creek Fire in 2. In 1. 99. 9, North West OHS released a study of confined space fatalities based on reports from the Occupational Safety and Health Administration OSHA, National Institute of Occupational Safety Health NIOSH and the Mines Safety and Health Administration MHSA with a breakdown of their causes. Researchers believe that the following numbers are only a fraction of the fatal confined space accidents that actually occurred as many locations are not initially identified as confined spaces, OSHA reports did not include non hazardous confined space fatalities in their studies prior to 1. NIOSH still do not include non hazardous confined space fatalities in their studies and many American states do not note the presence of confined spaces in fatality reports submitted to OSHA. Fire and Explosion OSHA 1. The majority of incidents were caused by worker error or faulty equipment. Lockout tagout OSHA 1. This category covers conveyor belts and machinery on the factory floor etc. Grain Handling OSHA 1. Toxic and Asphyxiating Atmospheres OSHA 1. Welding and Cutting OSHA 1. OSHA reports of welding and cutting deaths do not record whether or not an incident has occurred in a confined space, it is estimated that 2. Shipbuilding Repair OSHA 1. OSHA reports of shipbuilding deaths do not record whether or not an incident has occurred in a confined space, it is estimated that 3. Mining MSHA Report 1. According to data collected by the U. S. Department of Labor, Bureau of Labor Statistics, Census of Fatal Occupational Injuries program, fatal injuries in confined spaces fluctuated from a low of 8. Where a system of entry permits is in place, a rescue plan is required. It will list the personnel and equipment required to be at the worksite before entry is allowed. Special equipment such as tripod hoists, harnesses, and others may be required to extricate a worker from a toxic environment, without unduly endangering rescue personnel.
