Which activity should be prohibited in a room where oxygen therapy is provided?

Oxygen therapy involves the delivery of oxygen to patients to help with respiratory issues, and one significant concern is that oxygen is a highly combustible substance. Smoking introduces an open flame and produces heat, which can ignite any materials in the vicinity when oxygen is present, leading to a severe fire hazard. Thus, smoking inside a room where oxygen therapy is being administered is explicitly prohibited to ensure the safety of both the patient and healthcare providers.

While other activities like surfing the internet, texting, or watching TV may seem benign, they do not pose the same level of risk in terms of ignition and fire safety. The critical danger associated with the presence of oxygen makes smoking a distinctly hazardous activity in this context.
