Risk controls

The key to risk control is to prevent exposnre of those who could be at risk. In the workplace it is not possible to have no exposnre if anything is going to get done. It is important to limit the potential exposnre or amount of exposure. The basic principles of protection from radiation exposnre provide the fonndation for risk control. The three elements of exposnre control are distance, time, and shielding. Distance provides the best mechanism to prevent exposure. Distance can be physical distance or remote distance where robotics can provide the distance and limit the

Links between risk engineering and risk control 

The link between risk control and risk engineering involves taking into account the control strategies used by management and the fact that if hazards are controlled then the risk associated is also reduced. 

A range of countermeasures is available to lower employee risk. They involve reviewing  

Risk control options for reducing work activity injury 

Decisions concerning the cost-effective commitment of resources to the risk control program are easily made once the risk evaluation has been studied. Cost-effective risk reduction methods and time frames can also be compiled once the risk evaluation has been completed. 

To deal with the risks, a risk management plan is put into operation. This risk management plan is often referred to as the nuts and bolts of risk control and includes the four ways to handle risk treat, tolerate, transfer, or terminate. By incorporating a 

Structured safety system into the organization, risk control actions will be prioritized and risks will be dealt with on an ongoing basis. 

Establishing the status of the safety systems, controls, degree of management, and employee and union participation via means of risk assessment, and evaluating the physical risks in the woikplace, is a vital part of the safety culture shift process. This forms the foundation on which a positive safety culture is built. Risks in the workplace can only be managed once they have been assessed. Ongoing risk assessment is an important component of safety culture. 

If we can t live with the risk, what can we do about it Risk control is the second step of physical risk management after the risk assessment. 

Exposures to chemicals, resulting in toxic effects or oxygen-deficient atmospheres, may arise in a variety of industrial situations. A summary of common sources is given in Table 5.18 clearly this is not exhaustive since exposure may result whenever materials are mixed, machined, heated, dispersed or otherwise processed or used. 

The precautions naturally vary in each case. For example, to avoid improper admixture of chemicals will require

Reactivity Risks Controls and Risk Risks and Management Decisions... 

The team must be able to systematically identify abnormal situations involving chemical reactivity, estimate the likelihood of each abnormal situation occurring, and assess the consequences of each situation if it continues uncontrolled. The team must also be able to come to a consensus on where existing safeguards are inadequate and where risk control actions are needed. 

Regulatory officials nevertheless act on the basis of such hypothetical risks ( hypothetical definitely does not mean imaginary it means that the risk estimates are based on certain scientific hypotheses and that they have not been empirically tested). Such actions are in part based on legal requirements (Chapter 11) and in part on the prudence that is a traditional feature of public health policies. The scientific information, assumptions, and extrapolation models upon which risk assessments are based are considered sufficiently revealing on the question of human risk to prompt risk-control measures. To put off such actions until it is seen whether the hypothesized risks are real - to wait for a human body count - is considered to be an unacceptable course.
