Confined spaces present 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 provided by the Polar Group to assist in working within these environments.
What Is a Confined Space?
A confined space is defined as any area that is not designed for continuous human occupancy, has limited means of entry and exit, and insufficient ventilation to remove contaminants or correct oxygen levels. Common examples include tanks, silos, pipelines, and underground galleries. These environments are characterized by the difficulty of movement and work, poor or nonexistent natural ventilation, and restricted openings for entry and exit.
NR-33 and Accidents in Confined Spaces
The Regulatory Standard No. 33 (NR-33) was implemented to ensure safety and health in work conducted within confined spaces. This standard establishes protective measures that must be adopted before entry, during work, and upon exiting these environments. NR-33 aims to eliminate atmospheric hazards, 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 leading to poisoning, asphyxiation, or the formation of flammable/explosive atmospheres.
The Importance of Air Ventilation
Adequate ventilation is crucial in confined spaces to maintain safe oxygen levels and remove dangerous contaminants. According to NR-33, continuous ventilation should be initiated before entry and maintained throughout the entire work period within the confined space. This helps ensure thermal and respiratory comfort for workers, as well as prevent the formation of explosive and/or toxic atmospheres. Without proper ventilation, toxic gases such as methane, hydrogen sulfide, and carbon monoxide can accumulate, significantly increasing the risks of serious accidents.
