Question 3

Consequence

Answer 3

The measure of the expected effects of a specific incidents outcome case

Question 4

Enabling condition

Answer 4

Fractional probability that a particular circumstance exists in accounts for the time at risk

Question 5

Hazard

Answer 5

I didn’t hear its chemical or physical characteristic that has the potential for causing damage to people environment or the property

Question 6

Hazard evaluation or analysis

Answer 6

Determination of the mechanisms causing a potential incidence and evaluation of the incidence outcomes or consequences

Question 7

Hazard identification

Answer 7

Identification of a material prices plant characteristics that can produce undesirable consequences through the occurrence of an incident

Question 8

Impact

Answer 8

A measure of the ultimate loss and harm of an incident

Question 9

Incident

Answer 9

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

Question 10

Incident Outcome

Answer 10

Description of the physical manifestation of the incident this could include toxic release fire explosion and so on

Question 11

Incident outcome case

Answer 11

An incident with more than one outcome

Question 12

Individual risk

Answer 12

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.

Question 13

Likelihood

Answer 13

A measure of the expected probability or frequency of occurrence of an event for chemical plants the frequency is most commonly used

Question 14

Process safety

Answer 14

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.

Question 15

Risk

Answer 15

A measure of human injury, environmental damage, or economic loss in terms of both incident likelihood and the magnitude of a loss or injury

Question 16

Risk analysis

Answer 16

Quantitatively combining resist risk estimates for the variety of scenarios using engineering evaluation and mathematical techniques to arrive at an overall risk estimate

Question 17

Risk assessment

Answer 17

Applying the results of a risk analysis to make decisions

Question 18

Risk tolerance

Answer 18

The maximum willingness of a company, and society as a whole, to live with a risk to secure the resulting benefits.

Question 19

Safe guard

Answer 19

Design features equipments procedures and other resources in place to decrease the probability of initiating cars or mitigate the severity of a loss impact

Question 20

Safety culture

Answer 20

The common set of values, behaviors, and norms at all levels in a facility or in the water organization that affects processed safety

Question 21

Scenario

Answer 21

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

Question 22

Societal risk

Answer 22

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

Question 23

Loss prevention

Answer 23

Defined as incidents that cause losses due to death, injury, damage to the environment, or even loss of production or inventory
