A procedure for identifying potential failure modes in a system and classifying them according to their severity values. This method is usually carried out progressively in two parts. The first part identifies failure modes and their effects. The second part ranks failure modes according to the combination of severity and the probability of that failure mode occuring.
An analysis to verify system compliance with safety requirements contained in a system specs, and other applicable documents. Recognize previously unidentified hazards associated with the subsystem interfaces with system functional faults asses the risk associated with teh subsystem interfaces recommed action necessary to eliminate identifed hazards or control their associated risk to acceptable levels.
System hazard analysis
the initial effect in hazard analysis during the design phase with the purpose of recognizing the state of safety with all of the accopanying system implications. It focuses on system-level hazards that may be produced by the overall system. Its main objective is to identify system hazards as early as it practical and either eliminate or control them to acceptable levels.
Preliminary Hazard Analysis (PHA)
A broadly based hazard assessment technique that combines the creative thinking of a selected team of specialists with the methodical focus of prepared checklist. The result is a comprehensive hazard analysis that is extremely useful in training operation personnel on the hazards of the particular operation.
What if checklist
The analysis technique where individuals are interviewed about accidents and near misses involving fellow workers and about harmonious conditions that could result in accidents.
Critical Incident Techniques (CTC)
Optimum degree of safety within the application of system safety manangement and engineering principles through all phases (concept design, definintion, development, production, deployment) of a system's life cycle.
In a form of task analysis which breaks an operation down into activities and identifies the hazards associated with each activity (how to do the job safely/correctly and can be used to identify required PPE.
A failure of a component which results in the failure of the entire system.
Single pt failure
The inductive system analysis tecnique which identifes the manner in which failures occur and investigates their impact upon one another as well as other parts of the system
Failure Mode and Effect Analysis FEMA
Preliminary identification of risk assessment team members. It is inteneded to be a cross-functional team effort and relies on specialists from various discilines with appropriate skills and experience who display intuition and good judgment and have a broad and current knowledge of system deviations. HAZOP
Identifing and locating supporting data and information. Includes define scope, select team, plan the study, collect data, agree style of recording, estimate time, arrange schedule.
Select a part and define design intent. Identify deviation by using guide words on each element, consequences and causes, whether a significant problem exist, protection, detection and indicating mechanism, possible remedial/mitigating measures. Agree action then repeat for each element and then each part.
Record the examination, sign off the docs, produce the report of the study, follow up that action are implemented, re study any parts of system if necessary and produce final output report.
Documentation and follow up
The deducgtive system safety technique that starts with an undesired even and analyzes the way the undesired even can occur is know as
fault tree analysis
Fail safe - passive
Emergency lights or alarms
fail safe - active
Valve on a boiler
fail safe - operational
Types of redundant systems are
series redundant, single/double parallel, and standby
typical failure rates for products plotted over time
sets of events and probabilities that exist
placing losses divided by premium
Goals should be straight forward and emphasize what you want to happen
Establish concrete criteria for evaluating progress towards the attainment of each goal.
A goal needs to stretch you slightly so you feel you can do it and it will need a real commitment
The skills needed to do the work are available
A driver safey program should include the follow 5 things plus
implementing a program of driver selection, training, and supervision.
One function of the safety engineer is ensuring safe design the best is accomplished by
reviewing design with the engineers from initial planning through completion of construction.
OHSAS 18001 and accompanying OHSAS 18002 guildlines for the implementation of OHSAS 18001 were developed to provide a recognizeable occuational health and safety management system standard against which their management system can be assessed and verified. It was developed to be compatible with
ISO 9000:2008 Quality and ISO 14001:2004
The advantages of an effective OHSAS management system include:
Provides a structured approach for managing OHS
Establishes and maintains a commitment to occupational health and safety
Deomonstartes strong commitment to safety excellence
Organizational structures in place with clear roles and responsibilities
Existence of a continuous improvement culture
Strong levels of trust and communication
Reduction in incident levels with increased measure of performance
Contributes to business performance by reducing cost and liabilities
OHSAS 18001 is based on: Hazard identification, Risk assessment, and
Determination of applicable controls - Measures relevant to plan
The first clause of OHSAS 18001 standard requires that a company
Establish, document, implement, and continually improve their occupational health and safety management system and demonstrate that they meet all the requirements of the standard.
The implemetation and operation section of OHSAS 18001 indicates the ultimate responsibility for OH&S and OHSMS rest with
Which of the following is not doc requirement of OHSAS 18001
All OHSAS 18001 required activities need to be docu in procedures so that system requirements can be verified. (151)
When do you have to review the OHSMS?
at planned intervals
Conditions and factors that affect, or could affect, the health and safety of employees or other workers, visitors, or any other person in the workplace.
OHSAS 180001 defines Occupational Health and Safety
Combination of the likelihood of an occurrence of a hazardous event or exposures and the severity of injury or ill health can be caused by the event or exposure (154)
Need to be followed to implement an environmental management system based on the ISO standards
1. Environemental Policy
3. Implementation and oepration
4.Checking and corrective actions
The common component to join the remaining elements
Hazard identification and risk assessment rquirements
Identification of hazards

Implementation of controls
ISO 14001 addresses the establishment of an EMS. It includes responsibilites, authories, relationships, functions, processes, practices, procedures and
provides a framework for a holistic, strategic approach to the organizations environemental policy plans and actions
requires the organizations itself to audit it quality system to verify it is managing its processes effectively.
Is OSHMS more advanced then EMS and ISO 14001
to use recognized managment system principles, compativble with quality and environemental management system standards such as the ISO 9000 and ISO 14000 series
to provide guidelines for the certification of safety and health organizations
Good reason to deny workers comp
they intentional hurt themselves
4 steps of conducting a training needs assessment is
Identify priorites and importance
Identify causes of performance problems
IDENTIFY POSSIBLE SOLUTIONS AND GROWTH OPPORTUNITIES
Room with too much light
have the employees sit further from the screen
Not a need for adult learners
sessions less than 4 hours
Adults learn best when they have opportunity to adjust the training schedule to their personal schedule
ADult learners appreicate abstract info and theory discussion before learning a task
not a correct stament
Advantage of on the job training
its productive as the employee is still working as they are learning.
On the job training, group methods, and individual methods.
Four steps of a JIT:
present a demo
observe the worker
Adults find it easier to read cap text then lower and upper case
