Final answer:
The statement is false; extra precautions are indeed necessary during oxygen therapy to prevent fire hazards and ensure safety due to oxygen's ability to support combustion.
Step-by-step explanation:
The statement 'There are no extra precautions needed when oxygen therapy is in use' is false. When oxygen therapy is in use, additional safety measures are required. Oxygen supports combustion, and materials catch fire more easily in an oxygen-enriched environment. Therefore, it is critical to avoid open flames, sparks, or smoking around oxygen equipment. Furthermore, electrical devices should be properly maintained to prevent sparks and materials that easily ignite, like oils and grease, should be kept away. In medical settings, personnel are trained to use oxygen cautiously and to ensure all equipment is used per safety regulations to prevent accidents.
