Confined spaces pose a significant challenge to worker safety due to their restrictive nature and the presence of atmospheric hazards. In this article, we will discuss the concept of confined spaces and some solutions offered by the Polar Group to assist in working in these environments.
What Is a Confined Space? A confined space is defined as any area not designed for continuous human occupancy, with limited means of entry and exit, and insufficient ventilation to remove contaminants or correct oxygen levels. Common examples include tanks, silos, pipelines, and underground tunnels. These environments are characterized by difficult movement and work conditions, poor or non-existent natural ventilation, and restricted openings for entry and exit.
The NR-33 and Accidents in Confined Spaces
Regulatory Standard No. 33 (NR-33) was implemented to ensure the safety and health of work conducted in confined spaces. This standard establishes protective measures that must be adopted before entry, during work, and upon exit from these environments. NR-33 aims to eliminate atmospheric risks, such as contaminant concentrations and inadequate oxygen levels, which are the main causes of accidents in these spaces. According to the Occupational Safety and Health Administration (OSHA), atmospheric hazards are responsible for most accidents in confined spaces, potentially causing intoxication, asphyxiation, or the formation of flammable/explosive atmospheres.
The Importance of Air Ventilation
Proper ventilation is crucial in confined spaces to maintain safe oxygen levels and remove dangerous contaminants. According to NR-33, continuous ventilation must begin before entry and be maintained throughout the work period in the confined space. This helps ensure the thermal and respiratory comfort of workers, as well as prevent the formation of explosive and/or toxic atmospheres. Without adequate ventilation, toxic gases such as methane, hydrogen sulfide, and carbon monoxide can accumulate, significantly increasing the risk of serious accidents.
