Common Hazards That Make Confined Spaces Dangerous

Common Hazards That Make Confined Spaces Dangerous

Posted by William Kimmell on 8th Apr 2022

Working in a confined space poses a significant risk in a range of manufacturing settings. Enclosed spaces are areas that are broad enough for employees to access but that feature limited or restricted entry or exit ways; employees shouldn't continuously occupy these spaces. Recognizing these spaces' threats is key to protecting yourself and others. Look below to explore common hazards that make confined spaces dangerous.

Toxic Atmospheric Threats

You can categorize atmospheric hazards into two types. The first involves low oxygen levels that can induce asphyxiation. Other gases such as nitrogen or carbon dioxide replace breathable air in these cases. The second hazard involves inhaling harmful airborne contaminants such as toxic gases, fumes, vapors, and dust particulate.

Because of these dangers, personal and fixed gas monitors are essential. Sensors and systems track concentration levels and environmental fluctuations. These devices can then communicate to both the worker and the team positioned outside the confined space.  

Sudden Flooding

Liquids can rapidly fill an enclosed area, especially in drainage or sewage operations. When this happens, anyone inside could become trapped and potentially drown. Solid substances can also saturate confined spaces, putting anyone inside at risk of becoming pinned or buried.

Fires and Explosions

Flammable vapors, liquids, gases, and dust can all contribute to the danger of fires and explosions. When you employ any hot works or ignitable equipment in a confined space, your fire risks can exponentially increase.

Any explosive or flammable materials must have a concentration of less than 10 percent of its Lower Explosive Limit. Also, you need to monitor the area to ensure the oxygen content hasn't been enriched.

Body Temperature Risking Quickly

Construction labor, hot work, or naturally hot environments can cause a significant rise in body temperature, which becomes a severe issue in tight areas. In addition, due to the general contained characteristic of a confined space, heat can quickly rise, causing heatstroke, fatigue, or collapse.

You'll need to use a combination of engineering and personal protective equipment to bring the temperature in the space under control. Consider using a supplied-air respirator with vortex cooling to cool air up to 50 degrees in these circumstances.

Knowing the common hazards that make confined spaces dangerous enables you and your organization to take measures to protect workers. The more safety measures and equipment you use, the less likely it is that you will have a significant accident.
