One of the vital tools of the trade for confined space workers is a portable multi-gas meter which is used to provide an instant audio or visual indication of the presence of a harmful gas or vapor.įor the most part, these meters will monitor a handful of the most common gases, with the most common being oxygen, carbon monoxide, hydrogen sulfide and lower explosive limit (LEL). Realistic training for confined space entry

Personnel will need to don full working breathing apparatus and be supported by additional personnel who are responsible for overseeing safe entry and exit.

High Risk confined spaces will be ones where there is a known hazard that either cannot be controlled or that cannot be eliminated, but where work must be carried out regardless of that risk. The time needed to exit a Medium Risk area is also typically greater, whether due to the distance travelled from the point of entry or the fact that more than one worker is operating within the same environment.Įscape breathing apparatus will need to be used and one or more workers stationed outside the area to control access and handle any problems that may arise. In Medium Risk confined spaces there is a higher expectation of encountering one or more specified risks. In areas that are defined as Low Risk, for example, there will be an easy entry and exit route, with some natural ventilation and no requirement for the use of Emergency Escape Breathing Apparatus or the donning of escape equipment. Understandably of course, not all confined space environments present the same level of threat. Assessing the risk of the confined space environment

Thirdly, there is the also need to regularly inventory all equipment and to repair or replace as necessary. It is also important to thoroughly scrutinise the permit required confined space procedures that are currently in place, and to assign and correctly train workers and rescuers. The first task, he says, is to create a well-designed rescue plan that can be properly and realistically executed. In order to improve the statistics on confined space injuries and fatalities, Koester believes it is vital that every business carries out a "reality check" of its processes, its emergency procedures and its inventory of equipment. Of 100 incidents that were investigated in 2018, just 31% of facilities had some form of written confined space entry procedure - but none had put these written procedures into practice during the incident in question.Īnd while 15% of personnel had received confined space training, none of the facilities had any type of formal rescue plan in place. The statistics paint an alarming picture. He also points to multiple instances of insufficient or incorrect equipment, poorly maintained equipment - and in some cases, a lack of any equipment at all. Koester highlights shortfalls in the quality of confined space entry and rescue training - and a lack of understanding of the most common hazards that can be encountered within these environments. Writing in Occupational Health and Safety (OHS) Online, Missouri Fire Department Captain and Emergency Response Consultant, Chris Koester, explains what he believes are the root causes of incidents of serious injury or death during the course of confined space entry work. Reality checking plans, processes and equipment In just over half of all cases of worker fatality in confined spaces, it is exposure to some form of atmospheric hazard that is the leading cause of death - with the two most common culprits being hydrogen sulfide and carbon monoxide. In the period between 20, a total of 1030 workers were reported as having died as the result of occupational injuries that occured within a confined space - ranging from a low of 88 deaths in 2012 to a high of 166 in 2017. The presence of harmful gases or vapours within these environments can pose a significant threat to worker safety, with confined space entries having been documented as one of the leading causes of fatalities in the workplace. According to statistics released by the US Bureau of Labor, more than 2 million workers enter a permit required confined space environment every year for the purposes of routine maintenance, repairs, or inspections.
