Deadly force, also known as lethal force, is the use of force that is likely to cause serious bodily injury or death to another person. In most jurisdictions, the use of deadly force is justified only under conditions of extreme necessity as a last resort , when all lesser means have failed or cannot reasonably be employed.
"Mortal Wound" dictionary entry from The New World of English Words By Edward Phillips (1720). A mortal wound is an injury that will ultimately lead to a person's death. [1] [2] Mortal refers to the mortality of a human: whether they are going to live or die. [3] Wound is another term for injury. The expression can also be used figuratively. [3]
The United States Department of Defense defines the term as the process of determining the quantity of a specific type of lethal or nonlethal weapons required to achieve a specific level of damage to a given target, considering target vulnerability, weapon effect, munitions delivery accuracy, damage criteria, probability of kill and weapon ...
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
However, microbial damaging substances released by leukocytes would create collateral damage to surrounding tissues. [5] This excess collateral damage inhibits the healing process. Thus, untreated necrosis results in a build-up of decomposing dead tissue and cell debris at or near the site of the cell death. A classic example is gangrene.
Fentanyl. 2 mg (white powder to the right) is a lethal dose in most people. [1] US penny is 19 mm (0.75 in) wide. A drug overdose (overdose or OD) is the ingestion or application of a drug or other substance in quantities much greater than are recommended. [2] [3] Typically the term is applied for cases when a risk to health is a potential ...
The intense heat generated by a lightning strike can burn tissue, and cause lung damage, and the chest can be damaged by the mechanical force of rapidly expanding heated air. [ 4 ] Just as heat can cause expanding air in the lungs, the explosive shock wave created by lightning (the cause of thunder) can cause concussive and hearing damage at ...
Current: The higher the current, the more likely it is lethal. Since current is proportional to voltage when resistance is fixed , high voltage is an indirect risk for producing higher currents. Duration: The longer the shock duration, the more likely it is lethal—safety switches may limit time of current flow.
