Non-breathable

The adjective 'non-breathable' describes a material or environment that does not allow the passage of air or other gases necessary for respiration. This means that it is impossible or extremely difficult for a living organism to breathe or survive in this environment. The term highlights a critical aspect of safety, particularly in situations involving protective gear, hazardous materials, or environments with altered atmospheric compositions. Its use emphasizes the dangers associated with inadequate air supply or the presence of toxic substances that can impede or prevent respiration. The lack of breathability often leads to suffocation, asphyxiation, or other respiratory distress, and therefore careful consideration is required.

Non-breathable meaning with examples

• The heavy-duty hazmat suit, while offering protection from chemical spills, was unfortunately non-breathable, making it extremely uncomfortable and risky for extended wear. Workers needed frequent breaks to avoid heat exhaustion and potential respiratory problems. The engineers tried to find a solution to improve this situation, but faced many engineering challenges.
• The dense, airtight plastic sheeting used to seal the warehouse contained harmful chemicals and was non-breathable. Anyone inside would quickly exhaust the oxygen supply. The inspectors realized the safety concerns, so mandated the use of external air systems. This was done to keep the employees safe, and the warehouse was made compliant to regulations.
• During the simulated lunar mission, the astronauts practiced survival techniques in a non-breathable environment, enclosed in a pressurized habitat. This was done to acclimatize them to the difficult conditions of space and to keep them alive. They had to rely on their life support systems to ensure they got air to live and breath.
• The thick, waterproof tarp covering the hay bales was completely non-breathable. This caused significant moisture build-up, leading to mold and spoilage. This meant that the farmers would be left with lower crop yields and lower incomes as they struggled to sell what remained. The breathable replacement option was unavailable for the winter.
• After the volcanic eruption, the surrounding atmosphere became non-breathable due to the presence of noxious gases and ash. Evacuation became the top priority, with people being advised to avoid any exposure. Rescue workers and civilians alike used oxygen tanks or gas masks. They were provided by the emergency services.
