QRA Quantitative Risk Assessment:  Quantitative Risk Assessment, It is a formal and systematic approach to estimating the likelihood and consequences of hazardous events, and expressing the results quantitatively as a risk to people, the environment, assets, or reputation. A structured approach to assessing the potential for incidents and expressing this potential numerically. In QRA statistical values are derived for potential loss of life and damage to resources and the environment. Risk is the product of the measure of the likelihood of occurrence of an undesired event and the potential adverse consequences which the event may have upon, the health and safety of people fatality, injury, irreversible health impact or chronic ill health or harm to physical or psychological health. Environment - Water, air, soil, animals, plants and social, Reputation employees and third parties.

Qualitative OHRA: Qualitative OHRA is a descriptive measure and relies upon the determination of severity impact and probability of risk related to health hazards in the workplace taking into account existing control measures.

Quantitative OHRA:  Quantitative OHRA makes use of sampling and analytical techniques to quantify the exposure concentration of the hazardous agents to which the workers are potentially exposed, and uses data obtained to determine the likelihood of risk to health hazards.

Radioactive Waste: Radioactive waste is any waste containing radionuclides, a radioactive nuclide. Frequently categorized according to activity content and other criteria as low level, intermediate level, and high-level waste. The disposal of radioactive waste is subject to national and international legislation.

Radon Gas: Radon gas is an invisible, odorless, tasteless radioactive gas. It is formed by the disintegration of radium, which is a decay product of uranium. Some amounts of radon gas and radon daughters are present everywhere in the soil, water, and air. Particularly high radon levels occur in regions where the soil or rock is rich in uranium. Radon is emitted by radium in the ground, groundwater, and building materials. It can enter the indoor air where it and its decay products accumulate in poorly ventilated areas. Harmful levels of radon and radon daughters can accumulate in confined air spaces, such as basements and crawl spaces. Radon daughters are inhaled with air and deposited in the lungs. The resulting radiation dose increases the risk of lung cancer.

Recordable Incident: The recordable incident is an all incidents are recordable and logged in the organizations incident recording system if it is in any way associated with the employees or activities of organizations or a reportable contractor. The presence or absence of fault or preventability is not relevant in determining whether or not an incident, injury or illness is recordable.

Recycling: The recycling is reprocessing of waste into the same or a different product. Typical recyclable wastes include glass, paper, plastics, etc. Methods of recycling depend on the nature of the waste stream and whether or not sorting or treatment may be required to extract the reusable components.

Reduction: The reduction process of reducing the quantity of waste produced through the review of operational practices and optimal use of raw materials.

Restricted Areas: The restricted areas are defined based on the potential risk due to the existence of Hydrocarbon, Toxic Gases, chemicals, electrocution, etc. The restricted areas would be defined by each company respective to their business.

Restricted Work: The Restricted work activity occurs when the employee, because of the work-related injury or illness, is unable to perform all or any part of his or her normal assignment during all or any part of the normal workday or shift. The emphasis is on the employee’s inability to perform normal job duties over a normal work shift. Normally assigned work means any tasks that the employee performs or is expected to perform as part of their job. A case is not considered to be Restricted Work if the following three conditions are: 1. there is no medical treatment required, 2. the worker is fully capable of doing all tasks that had been scheduled to be performed during the period, 3. there have been no explicit restrictions placed on the worker by treating doctor.

Restricted Workday: The restricted workday cases a work-related injury or illness other than a fatality or lost the workday case which results in an individual being unable to perform all normally assigned work functions during any scheduled work shift; or being assigned to another job on a temporary or permanent basis after the day of the injury or illness. Less than normal assigned work functions include: Performing all duties or normally assigned work functions but at less than full-time schedule. Performing limited duties during a normally assigned full-time schedule.

Risk Assessment Matrix (RAM): The risk assessment matrix is a matrix used during risk assessment to define the various levels of risk based on its consequences and probability of occurrence

Risk Assessment: The risk assessment is documented process of identifying the hazards associated with the work to be done activity and specifying the controls required to reduce the risk to a level, As Low as Reasonably Practicable (ALARP).

Risk Reflects the likelihood (probability): of occurring hazard eventuating and its severity the consequence of the event. Risk is the product of the two, i.e., likelihood x severity = risk.

Risk: The risk is the product of the measure of the likelihood of occurrence of an undesired event and the potential adverse consequences that the event may have on the Health and Safety of People – Fatality, injury, irreversible health impact or chronic ill health, or harm to physical or psychological health; Environment - Water, air, soil, animals, plants and social; Reputation - Employees and third parties. This includes the liabilities arising from injuries and property damage to third parties including the cross liabilities that may arise between the interdependent.
