However, confined space hazards and precautions must always be assessed since there are other dangers associated with working in a confined space. Hazards in confined spaces can result in fire, explosion, unconsciousness, asphyxiation, or drowning. Hazard Identification & Risk Analysis to be considered with respect to safety aspect for all confined Space. It can be any space in which by virtue of its enclosed nature there arises a risk of … 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. 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. Does space contain other recognized safety or health hazards, Will welding, cutting, torch work, or other hot work be performed? Confined Space Hazards Introduction Confined space hazards can be divided into four broad and far reaching categories. 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. Before delving into specific concerns of confined spaces, you must first understand what constitutes a confined space. These need to be understood and controlled prior to rescue. However, they can be even more hazardous in a confined space than in a regular worksite. 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. The hazards of confined spaces include too little or too much oxygen and dangerous concentrations of gasses, vapors or combustible dusts. Inspection, repair and cleanup can produce physical and chemical hazards within these spaces. Confined spaces. Confined space incidents can happen suddenly, often without any warning that something is wrong. Atmospheric Hazards Physical Hazards Configuration Hazards What hazards can exist within a confined space? Confined spaces in the workplace pose a significant risk of injury and death. 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. Examples of hazards within combined spaces include unbreathable gases (which may be invisible), submersion in liquids or free flowing grain and risk of explosion. 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. The hazards found inside confined spaces can be divided into three categories. Those working in confined spaces must receive specific training. These categories are Configuration, Biological, Physical and Atmospheric. All hazards found in a regular workspace can also be found in a confined space.
