Exam 1 Flashcards
Accident
An unplanned events or a sequence of events that results in undesirable consequence the scope of the accident description is arbitrary
Conditional modifier
A fractional probabilityprobability that a Particular event occurs
Consequence
The measure of the expected effects of a specific incidents outcome case
Enabling condition
Fractional probability that a particular circumstance exists in accounts for the time at risk
Hazard
I didn’t hear its chemical or physical characteristic that has the potential for causing damage to people environment or the property
Hazard evaluation or analysis
Determination of the mechanisms causing a potential incidence and evaluation of the incidence outcomes or consequences
Hazard identification
Identification of a material prices plant characteristics that can produce undesirable consequences through the occurrence of an incident
Impact
A measure of the ultimate loss and harm of an incident
Incident
The basic description of an events or series of events resulting in one or more undesirable consequence such as harm to people damage to the environment or assist or business laws in general it is caused by loss of containment or control of material or energy or chemical plants this includes fires or explosions and releases of toxic or harmful substances not all events propagate to an incident
Incident Outcome
Description of the physical manifestation of the incident this could include toxic release fire explosion and so on
Incident outcome case
An incident with more than one outcome
Individual risk
The risk to a person in the vicinity of a hazard. This includes the nature of the injury to the individual, the likelihood of the injury occurring, and the time period over which the injury might occur.
Likelihood
A measure of the expected probability or frequency of occurrence of an event for chemical plants the frequency is most commonly used
Process safety
Disciplined framework for managing the integrity of operating systems and processes handling hazardous substances by applying good design principles, engineering and operating practices. It deals with the prevention and control of incidents that have the potential to release hazardous materials or energy. Such incidents can cause toxic affects, fires, or explosions, and could ultimately result in serious injuries, property damage, lost production, and environmental impact.
Risk
A measure of human injury, environmental damage, or economic loss in terms of both incident likelihood and the magnitude of a loss or injury
Risk analysis
Quantitatively combining resist risk estimates for the variety of scenarios using engineering evaluation and mathematical techniques to arrive at an overall risk estimate
Risk assessment
Applying the results of a risk analysis to make decisions
Risk tolerance
The maximum willingness of a company, and society as a whole, to live with a risk to secure the resulting benefits.
Safe guard
Design features equipments procedures and other resources in place to decrease the probability of initiating cars or mitigate the severity of a loss impact
Safety culture
The common set of values, behaviors, and norms at all levels in a facility or in the water organization that affects processed safety
Scenario
A detailed description of an unplanned event or incident sequence their result in a loss events and its associated impacts period the scope of the scenario is arbitrary period
Societal risk
A measure of a risk to a group of people period it is most often expressed in terms of the frequency distribution of multiple casualty events
Loss prevention
Defined as incidents that cause losses due to death, injury, damage to the environment, or even loss of production or inventory
Hazards can arise
Due to materials energy physical situations equipment design and even Procedures it could also be present or intermittent
