Another form of classification is “The Classification and Management of Confined Space Entries by Water UK” Here, confined space entries is defined under 4 categories, NC.1 to NC.4. Hazards in confined spaces can result in fire, explosion, unconsciousness, asphyxiation, or drowning. The hazards found inside confined spaces can be divided into three categories. These need to be understood and controlled prior to rescue. Confined spaces. The hazards of confined spaces include too little or too much oxygen and dangerous concentrations of gasses, vapors or combustible dusts. All hazards found in a regular workspace can also be found in a confined space. It can be any space in which by virtue of its enclosed nature there arises a risk of … Hazards in confined spaces can include: Poor air quality: There may be an insufficient amount of oxygen for the worker to breathe. Once a confined space is identified, its atmosphere must be hazard-rated as HIGH, MODERATE, or LOW. Other life-threatening situations can arise if the space has poor ventilation or if the work requires welding or the use of electrical or mechanical equipment that generates toxic fumes. The hazard rating of a confined space must be determined by a qualified person after considering the design, construction, and use of the confined space, the work activities to be performed, and all required engineering controls. Confined spaces in the workplace pose a significant risk of injury and death. Confined Space Hazards Introduction Confined space hazards can be divided into four broad and far reaching categories. A confined space is determined by the hazards associated with a set of specific circumstances and not just because work is performed in a small space. Hazard Identification & Risk Analysis to be considered with respect to safety aspect for all confined Space. Those working in confined spaces must receive specific training. However, confined space hazards and precautions must always be assessed since there are other dangers associated with working in a confined space. These categories are Configuration, Biological, Physical and Atmospheric. Atmospheric Hazards Physical Hazards Configuration Hazards What hazards can exist within a confined space? Confined space incidents can happen suddenly, often without any warning that something is wrong. Before delving into specific concerns of confined spaces, you must first understand what constitutes a confined space. Inspection, repair and cleanup can produce physical and chemical hazards within these spaces. Does space contain other recognized safety or health hazards, Will welding, cutting, torch work, or other hot work be performed? However, they can be even more hazardous in a confined space than in a regular worksite. Examples of hazards within combined spaces include unbreathable gases (which may be invisible), submersion in liquids or free flowing grain and risk of explosion. It is important to understand each of these groupings as they are often used in the classification of specific confined spaces hazards at a worksite.
