2. Risk Assessment & Permit To Work Risk: The chance or probability of occurrence of an injury, loss, or a hazard or potential hazard. Risk assessment: The process of assessing the risks associated with each identified hazard, in order to make decisions and implement appropriate control measures to prevent the hazard from occurring. Hazard: A condition with the potential to cause injury, illness, or death of personnel; damage to or loss of equipment or property; or mission degradation. Hazard identification: The process of examining each work area to identify the hazards associated with each job or task. Probability: The likelihood that a given event will occur. Severity: The degree of undesired consequences.

3. Risk Management Process

4. Hazard Identification Hazards are identified through experience, historical data, intuitive analysis, judgment, standards, brainstorming, and a large variety of other means and methods.

5. Risk Assessment (Risk= Probability * Severity) Probability: Frequent (A) Occurs very often, known to happen regularly. e.g. (1/500) Likely (B) Occurs several times, a common occurrence. e.g. (1/1,000). Occasional (C) Occurs sporadically, but is not uncommon. You may or may not complete a job or project without this incident occurring to someone. Seldom (D) Remotely possible, could occur at some time. Usually, several things must go wrong in order for it to occur. Unlikely (E) Can assume that the incident will not occur.

6. Severity Catastrophic: Death or permanent total disability; complete project failure or the loss of ability to complete the project; loss of major critical systems or equipment; severe environmental damage, unacceptable collateral damage. Critical: Permanent partial disability or temporary total disability of employees; severely degraded project capability; extensive major damage to equipment or systems; significant property or environmental damage; and significant collateral damage. Marginal: Lost work day injuries or illnesses; degraded project capabilities; minor damage to equipment or systems; or minor damage to the environment. Negligible: First aid or minor medical treatment; little or no adverse impact on project capability; slight equipment or system damage, but fully functional or serviceable; little or no property or environmental damage.

7. Qualitative Risk Assessment

8. Quantitative Risk Assessment Matrix BELOW 6 : “YELLOW” the risk is probably at an acceptable level; no specific control measure may be needed in most cases. FROM 6 to 12 : “GREEN” the risk is unacceptable and should be reduced to acceptable level, most likely by simple control measures. ABOVE 12 : “RED” the risk is unacceptable and must be reduced to acceptable level on priority basis.

11. Types of Controls Educational controls: These controls are based on the knowledge and skills of the employees or individuals performing the task. Effective control is implemented through individual and collective training that ensures performance to a standard. Physical controls: These controls may take the form of barriers and guards or signs to warn employees and others that a hazard exists. Additionally, special controller or supervisory personnel responsible for locating specific hazards fall into this category. Avoidance: These controls are applied when supervisors and managers take positive action to prevent contact or exposure with the identified hazard.

12. Criteria for Control Support. Availability of adequate personnel, equipment, supplies, and facilities necessary to implement suitable controls. Standards. Guidance and procedures for implementing a control are clear, practical, and specific. Training. Knowledge and skills are adequate to implement a control. Leadership. Supervisors and managers are competent to implement a control. Individual. Individual employees are sufficiently self-disciplined to implement a control measure.2

13. Developing and Implementing Controls A key element in developing and implementing control measures is to specify who, what, when, where, and how each control is to be used. Decision Making! William Fine!!

14. Implement Controls Managers and supervisors must ensure that controls are integrated into the standard operating procedures, written and verbal instructions, and toolbox talks prior to the beginning of the project or task. The critical check for this step, with oversight, is to ensure that controls are converted into clear, simple instructions understood at all levels . Implementing controls includes coordination and communication with appropriate superiors and employees.

15. Supervise and Evaluate Methods to supervise and evaluate the effectiveness of control measures include spot checks, inspections, daily reports, and close, direct supervision. After the project or task has been completed, it is recommended that a post-project evaluation, which includes all employees on the project, be conducted. The results of this post-project evaluation, and any changes, should be maintained in the project file, for future use.
