What is a risk management tool?
- This tool/technique actually transcends several of the risk management steps, because you must identify and assess hazards, but is best considered a control used to manage the hazards that must remain in the workplace for mission accomplishment.
Why is risk management important?
- 4. The goal of risk management is to accomplish a balance between performance at the height of one’s potential and still maintain a safe working environment effectively controlling known hazards. Compliance with existing codes and federal, state and local regulations is often viewed as being quite expensive to implement. However
What makes a good safety management system?
- Organizations with strong safety management systems frequently embed safety into their core values, which are visibly embraced by corporate leadership. Often, they even work to build a safety culture by introducing behavioural safety programs that target safety outside of the workplace and at home.
What is risk specific training?
- Risk specific training is provided for those individuals that are associated with hazards having unacceptable residual risks that may not be competent on the basis of education, training or experience. Competency As needed the organization

■Failure mode and effects analysis (FMEA)The HAZOP Method■
HAZOP analysisis a systematic technique for
identifying hazards and operability problems throughout an entire facility. It is particularly useful to identify unwanted hazards designed into facilities due to lack of information, or introduced into existing facilities due to changes in process conditions or operating procedures.The objectives of a HAZOPstudy are to detect any
predictable deviation (undesirable event) in a process or a system. This purpose is achieved by a systematic study of the operations in each process phase.The HAZOP Method■
The system is divided into functional blocks
Every part of the process is examined for possible deviations from the design intentionCan the deviations cause any hazard or
inconvenience?Every phase of the process
Each system and person
Questions formulated around guide words
Each deviation is considered to decide how it could be caused and what the consequences would beFor the hazards preventive/remedying actions are

Definition of the objectives and scope of the study, e.g. hazards having only off-site impact or only on- site impact, areas of the plant to be considered, etc. 2.Assembly of a HAZOP study team.
3. Collection of the required documentation, drawings and process description. 4.Analysis of each major item of equipment, and all
supporting equipment, piping and instrumentation 5.Documentation of the consequences of any
deviation from normal and highlights of those which are considered hazardous and credible.HAZOP Study team■HAZOP studies are normally carried out by multi-disciplinary teams. There are two types of team members, namely those who will make a technical contribution and those play a supporting and structuring role.

Example of HAZOP Matrix
Criticality- combination of severity of an effect and the probability or expected frequency of occurrence. The objective of a criticality analysis is to quantify the relative importance of each failure effect, so that priorities to reduce the probabilityor to mitigate the severitycan be taken. Example formula for Criticality:Cr = P ×B ×S Cr : criticality numberP: probability of occurrence in an yearB: conditional probability that the severest consequence will occurS: severity of the severest consequenceHAZOP Criticality analysis
The criticality number- used to rank the identified deviations in a HAZOP or FMEA study - cannot be used as a risk measure - product of three rough estimatesBefore a criticality analysis can be performed guidelines have to be developed on how to determine P, Band S. There are no generally accepted criteria for criticality applicable to a system.HAZOP Criticality analysisCategories
