The accident analysis diagram example "Accident analytic tree" was redesigned from the picture 7-14 from the "DOE Workbook. Conducting Accident Investigations. Revision 2."
"Analytic tree analyses are well defined, useful methods that graphically depict, from beginning to end, the events and conditions preceding and immediately following an accident. An analytic tree is a means of organizing information that helps the investigator conduct a deductive analysis of any system (human, equipment, or environmental) to determine critical paths of success and failure. Results from this analysis identify the details and interrelationships that must be considered to prevent the oversights, errors, and omissions that lead to failures. In accident investigations, this type of analysis can consist of both failure paths and success paths, and can lead to neutral, negative, or positive conclusions regarding accident severity.
TIP.
An analytic tree enables the user to:
(1) Systematically identify the possible paths from events to outcome.
(2) Display a graphical record of the analytical process.
(3) Identify management system weaknesses and strengths."

The vector stencils library "Fault tree analysis diagrams" contains 12 symbols for drawing Fault Tree Analysis (FTA) diagrams.
"Fault tree analysis (FTA) is a top down, deductive failure analysis in which an undesired state of a system is analyzed using Boolean logic to combine a series of lower-level events. This analysis method is mainly used in the fields of safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk or to determine (or get a feeling for) event rates of a safety accident or a particular system level (functional) failure. FTA is used in the aerospace, nuclear power, chemical and process, pharmaceutical, petrochemical and other high-hazard industries; but is also used in fields as diverse as risk factor identification relating to social service system failure.
In aerospace, the more general term "system Failure Condition" is used for the "undesired state" / Top event of the fault tree. These conditions are classified by the severity of their effects. The most severe conditions require the most extensive fault tree analysis. These "system Failure Conditions" and their classification are often previously determined in the functional Hazard analysis." [Fault tree analysis. Wikipedia]

How to Create a Fault Tree Analysis Diagram (FTD) in ConceptDraw PRO

Fault Tree Diagram are logic diagram that shows the state of an entire system in a relationship of the conditions of its elements. Fault Tree Diagram are used to analyze the probability of functional system failures and safety accidents. ConceptDraw PRO allows you to create professional Fault Tree Diagrams using the basic FTD symbols. An FTD visualize a model of the processes within a system that can lead to the unlikely event. A fault tree diagrams are created using standard logic symbols . The basic elements in a fault tree diagram are gates and events.

The vector stencils library "Fire safety equipment" contains 19 clipart images of fire safety equipment which you can easy use in your presentations and illustrations.
"Fire safety refers to precautions that are taken to prevent or reduce the likelihood of a fire that may result in death, injury, or property damage, alert those in a structure to the presence of an uncontrolled fire in the event one occurs, better enable those threatened by fire to survive in and evacuate from affected areas, or to reduce the damage caused by a fire. Fire safety measures include those that are planned during the construction of a building or implemented in structures that are already standing, and those that are taught to occupants of the building.
Threats to fire safety are referred to as fire hazards. A fire hazard may include a situation that increases the likelihood a fire may start or may impede escape in the event a fire occurs." [Fire safety. Wikipedia]
The clip art example "Fire safety equipment - Vector stencils library" was created in the ConceptDraw PRO diagramming and vector drawing software using the Presentation Clipart solution from the Illustration area of ConceptDraw Solution Park.
