Toxic atmospheric hazards can be roughly divided into two categories: Asphyxiation caused by low levels of oxygen. Interestingly enough, many physical hazards and injuries are connected to atmospheric ones: exposure to low oxygen levels or toxic gases might lead to a worker losing consciousness and falling from a great height or drowning in a pool of liquid. This process can occur in less than 6 minutes, too, so theres little time for rescue. This covers the protective equipment they should use on-site and the safety practices the workers should observe the entire duration of their shifts.

To effectively control the risks associated with working in a confined space, a confined space hazard assessment and control program should be implemented for your workplace. CFOI considers a workplace fatality to involve a confined space if an aspect of the fatal incident occurred in a confined space based on the documents and information available in each fatal work injury case.

[1] CFOI has used the Standard Occupation Classification (SOC) 2010 system since 2011 to define occupation. According to OSHA and NFPA, the atmosphere of a confined space is only safe for workers when oxygen concentration is 19.5 to 22 percent by volume; the concentration of a flammable vapor in the atmosphere is less than 10 percent by volume of its lower explosive limit; any toxic materials in the atmosphere are within permissible concentrations at the time of the inspection; and the residues and chemicals remaining in the confined space arent capable of producing toxic material concentrations above that permissible level. During the emergency response, the local authorities contacted an NFPA-certified marine chemist who happened to be working in a nearby location. For more information on SOC, see our definitions page at https://www.bls.gov/iif/definitions/census-of-fatal-occupational-injuries-definitions.htm. a.
