Aryabhatiya, written by Aryabhata in the 5th century CE, contains a chapter on risk assessment called the 'Ganita Pada'. This chapter provides methods for calculating the probability of a hazardous event occurring, as well as the potential consequences of such an event.

Anka ganita is a method of calculating probabilities that was developed by Indian mathematicians in the 5th century CE. It is based on the idea that the probability of an event occurring is equal to the number of favorable outcomes divided by the total number of possible outcomes.

Ashtavarga is a method of calculating the severity of a hazardous event that was developed by Indian mathematicians in the 5th century CE. It is based on the idea that the severity of an event is determined by eight factors: fire, water, earth, air, ether, time, space, and direction.

Ganita Sara Sangraha, written by Mahavira in the 9th century CE, contains a chapter on hazard identification called the 'Vyavahara Pada'. This chapter provides a list of potential hazards that may be present in an industrial facility, as well as methods for identifying these hazards.

The 'Vyavahara Pada' of Ganita Sara Sangraha classifies hazards into four categories: natural hazards (e.g., earthquakes, floods, and hurricanes), man-made hazards (e.g., fires, explosions, and chemical spills), technological hazards (e.g., machinery accidents and computer failures), and environmental hazards (e.g., air pollution, water pollution, and soil contamination).

Lilavati, written by Bhaskara II in the 12th century CE, contains a chapter on risk management called the 'Vyavahara Bija Ganita'. This chapter provides methods for developing strategies for preventing or mitigating the risks associated with industrial hazards.

The formula for calculating the vyavahara bija is Vyavahara bija = (Likelihood of occurrence) x (Severity of consequences). The likelihood of occurrence is a measure of how likely it is that the hazard will occur, while the severity of consequences is a measure of the potential consequences of the hazard occurring.

Prayoga is a method of conducting experiments that was developed by Indian mathematicians in the 12th century CE. It is based on the idea that the best way to learn about a phenomenon is to conduct experiments and observe the results.

Aryabhatiya, written by Aryabhata in the 5th century CE, contains a chapter on data analysis and mathematical modeling called the 'Ganita Pada'. This chapter provides methods for analyzing data collected from experiments and developing mathematical models of industrial hazards.

A ganita yantra is a mathematical model of an industrial hazard. It is a set of equations that describes the behavior of the hazard and can be used to predict the potential consequences of the hazard occurring.

Upaya is a method of developing strategies for preventing or mitigating the risks associated with industrial hazards. It is based on the idea that the best way to prevent or mitigate a risk is to identify the root cause of the risk and then develop a strategy to address the root cause.

Lilavati, written by Bhaskara II in the 12th century CE, contains a chapter on risk communication called the 'Vyavahara Bija Ganita'. This chapter provides methods for communicating the results of risk assessments to decision-makers.

A vyavahara bija patra is a risk communication document that is used to communicate the results of a risk assessment to decision-makers. It typically includes a description of the hazard, the likelihood of occurrence, the potential consequences, and the recommended strategies for preventing or mitigating the risk.

Samvada is a method of engaging stakeholders in the risk management process. It is based on the idea that the best way to manage risk is to involve all stakeholders in the process and to get their input on the best way to prevent or mitigate the risk.

Aryabhatiya, written by Aryabhata in the 5th century CE, contains a chapter on risk evaluation called the 'Ganita Pada'. This chapter provides methods for evaluating the effectiveness of risk management strategies.
