Controlled risk, defined

Over the years, scientific research with human subjects has provided valuable information to help characterize and control risks to public health, but its use has also raised particular ethical concerns for the welfare of the human participants in such research as well as scientific issues related to the role of such research in assessing risks. Society has responded to these concerns by defining general standards for conducting human research. As an example, studies carried out for the authorization of a medical product, have to be conducted in line with the World Medical Association s Declaration of Helsinki, which describes the general ethical principles for medical research involving human subjects (World Medical Association 2004). The Helsinki Declaration was first issued by the World Medical Association in 1964 and has been revised several times since then. 

Passage of the Pollution Prevention Act (PPA) by the U.S. Congress in 1990 ushered in a new era in the philosophy of controlling risks from toxic chemicals. The PPA declared it to be the policy of the United States that pollution should be prevented at the source when possible, and it defined source reduction as any practice that ... 

Using the responsibilities and control actions defined for the components of the safety control structure, the STAMP-based risk analysis applied the four general types of inadequate control actions, omitting those that did not make sense for the particular responsibility or did not impact risk. To accomplish this, the general responsibilities must be refined into more specific control actions. 

As per ISO guide 73, risk management stands for, coordinated activities to direct and control an organization with regard to risk," defined in Clause 2.3. 

In this Final Rule, U.S. HUD sets forth seven strategies for lead paint or paint hazard evaluation and hazard reduction, varying in relative stringency from least to most (1) safe work practices during rehabilitation (2) ongoing lead paint maintenance practices to assure continued intact surfaces (3) visual assessment and paint stabihzation (4) risk assessment and interim controls (as defined above) (5) combined risk assessment and lead paint inspection with interim controls (6) risk assessment and abatement of lead paint hazards and (7) lead-based paint inspection and abatement via removal of aU lead paint.

Refer to Chapter 9, Risk Perception— Defining How to Identify Personal Responsibility , and Chapter 10, Risk Management Principles , for a detailed discussion on a method to help identify risk perception and controlling risk. 

JHAs can be used as a problem-solving tool useful in assessing the potential for loss-producing events. Each job element has inherent hazards that have varying levels of risk (severity and probability). The JHA provides a structure that allows these elements to be analyzed and the desired proper controls better defined. 

Further, partially controllable risks include data transfer between CAD systems. Although a designer cannot affect the type of exported or imported file, by means of parameter settings that are required for a particular file type such as defining tolerances, sizes, and shapes of items used, with, for example, the FEM, the designer may prevent potential risks of imprecise data transfer (3-D model enhancement) or data loss during transfer. 

The measured LTI-rate for a period is an estimate of the underlying or true LTI-rate. From the statistical theory presented in Chapter 9 we know, however, that this estimate is uncertain and that we must expect the rate to fluctuate from period to period due to pure chance. The upper and lower control limits define the range in between which the LTI-rate will fall on average in 19 out of 20 periods, provided that the underlying accident risk at the company is unchanged. These limits are calculated from the mean LTI-rate during the studied periods, since this is considered to be the best estimate of the true LTI-rate. 

The requirements for the system are established in Phase 1, starting with the identification of activities that may affect operational safety and occupational health and safety (Principle 1). The risk assessment, with control measures, identifies those activities where the competence of people to control risks is important. This leads to defining and selecting the competence standards for individuals to enable them to control risks consistently (Principle 2). 

Obvious hazards are identified through JHA process and less obvious hidden hazards become visible as the systematic analysis of each job step and related task are confirmed and reviewed. By combining the identification of potential loss-producing events with a risk analysis, better preventive measures and controls are defined. A uniform JHA approach provides a consistent method for developing effective employee selection and training programs that better ensure that a safe and effective work methods are employed. Refer to Table 1.1 for a list of why JHAs are important. 

The Hierarchy of Controls as defined by the ANSI/AIHA/ASSE, ZIO provides a systemic way to determine the most effective feasible method to reduce risk associated with the hazard (Occupational Health Safety Management Systems, 2012)(Figure 7.3).The Hierarchy of Controls follows a tiered approach that begins with total hazard avoidance and ends with personal protection if the hazard(s) cannot be eliminated. 

SALE SYSTEM OF WORK A foiTual pt ocedufe resulting from systematic examination of a task to identify all the hazards. Defines safe methods to ensure that hazards are eliminated or risks controlled.
