What Are the Safety Concerns Associated with Food-Grade Nitrous Oxide?

While food-grade nitrous oxide（https://www.rotasswhip.com/n2o-cylinders） is generally safe for its intended use in food products, significant safety concerns arise from inhalation:
Asphyxiation: Inhaling nitrous oxide can displace oxygen in the lungs, leading to oxygen deprivation and potentially fatal asphyxiation.  
Nerve Damage: Prolonged or repeated inhalation can cause peripheral neuropathy, a condition that damages the nerves in the extremities, leading to numbness, tingling, and muscle weakness.  
Vitamin B12 Deficiency: Nitrous oxide can interfere with vitamin B12 metabolism, potentially leading to neurological problems.  
Other Potential Risks:
Frostbite: Direct contact with liquid nitrous oxide can cause severe frostbite.  
Inhalational Injuries: High concentrations can irritate the respiratory tract.  
Loss of Consciousness: Inhalation can cause dizziness, lightheadedness, and even loss of consciousness.
