An injury is defined as physical harm to the body that happens as a result of exposure to some form of energy that exceeds the body's tolerance. Is this statement True or False?

• A. Not Applicable
• B. Cannot Be Determined
• C. False
• D. True

Answer: (D)

At its heart, injury in safety terms means physical harm caused when energy transferred to the body exceeds what the body can tolerate. The body can absorb or dissipate energy up to a certain limit; when the energy transfer goes beyond that limit, tissue damage occurs, producing injury. This framework covers the main ways energy can cause harm—mechanical, thermal, electrical, chemical, and others—by focusing on the threshold at which energy becomes damaging. The statement correctly ties physical harm to an energy exposure that surpasses the body's tolerance, which is why it’s considered true. If energy stays within the body's tolerance, injury is not produced, even though a hazard might be present.
