Downloaded from https://www.everyspec.com Restricted area Any area, usually fenced, at an establishment where the entrance and egress of personnel and vehicular traffic are controlled for reasons of safety and/or security. Rigger-in-charge The rigger-in-charge has overall control of the operation including:
planning all aspects of the lift; determining the weight of the load to be lifted; establishing the appropriate method of communication with the operator; ensuring the load is properly rigged; ensuring the operating envelope remains clear of all obstructions; providing signals to the operator; and conducting the operation in a safe manner (see source for management of weight handling equipment Navy Facility P–307). Riot control agent A substance that produces temporary irritating or disabling physical effects that disappear within minutes of removal from exposure. There is no significant risk of permanent injury, and medical treatment is rarely required.
Risk Risk is directly related to the ignorance or uncertainty of the consequences of any proposed action. Risk is an expression of possible loss in terms of hazard severity and hazard probability. Risk is the expected value of loss associated with a loss caused by a hazard expressed in dollars. The risk associated with this loss is mathematically derived by multiplying the probability of the loss’s likelihood of occurrence by the probable dollar loss associated with the loss’s severity. Note that risk has two dimensions—likelihood and magnitude, while a hazard has only one—varied magnitude.
Risk acceptability Risk Acceptability is that level of risk which has been determined as tolerable in order to fulfill mission requirements. It represents a level of risk where either the output of resources to rectify safety deficiencies does not result in a proportional increase in the level of safety be provided; or so restricts the performance that the assigned mission cannot executed.
Risk acceptance Risk acceptance is a formal and documented process indicating Army leadership understands the hazard, its associated cause, and the probable consequences to mission, personnel, equipment, public and/or the environment and that they have determined that the total risk is acceptable because of mission execution. Risk acceptance is an Army leadership prerogative. Risk assessment An evaluation of a risk in terms of loss should a hazard result in an accident and against the benefits to be gained from accepting the risk. Risk acceptance level Risk Acceptance Levels are used to denote the level of risk a particular level of Army Leadership and Management may accept.
These levels are based on the magnitude of the risk involved and the duration of the risk acceptance. Risk decision The decision to accept or not accept the risk(s) associated with an action; made by the commander, leader, or individual responsible for performing that action and having the appropriate resources to control or eliminate the risk’s associated hazard. Rocket A motor which derives its thrust from ejection of hot gases generated from propellants carried within the motor casing. ROTC personnel Definition: 1.
