W20-W49: Exposure to inanimate mechanical forces

W40: Explosion of other materials

"Explosion of other materials" forms a category of conditions arising from accidental exposure to explosive forces other than those classified under bomb explosions or fireworks. These conditions occur due to a person being near an uncontrolled, rapid release of energy in the form of a shock wave or blast wind, often from ignitable gases, vapors, liquids, or dust. Typical symptoms can vary based on the severity and proximity of the explosion, but may include burns, injuries from flying debris, hearing loss from the loud blast, and mental trauma. Potential injury severity can range from minor superficial wounds to life-threatening systemic damage, such as lung injuries and traumatic brain injuries. Irrespective of the material triggering the explosion, this group of conditions primarily affects the body's integumentary (skin), auditory and nervous systems. Immediate interventions typically address wound management, burns care, and trauma support, but further effects may require specialized and long-term medical attention.
