Workplace Precautionary Principles Internal Validity Internal validity is the evidence provided to show that a particular a particular intervention leads to specific results. It is usually used in studies that try to investigate the reason why an event happens. Additionally, it is used in intervention programs in to study whether the intervention was successful or not. Additionally, internal validity is used to find out whether the changes realized are as results of the intervention or not. However, the relevance of the validity is limited to the study conducted only. A good example can be demonstrated by investigating the effects of training to performance of employees. If the trained employees perform better than the untrained, then …show more content…
The revelations provided by the company’s record indicate that male workers between the age of 28 and 38 are leaving work or having more sick days than workers in other departments. The health of the employees is supposed to be upheld to ensure that they are able to perform their duties. Although there is no direct link between Titanium Glycol and the harmful side effects in male workers, there has been a general observation that suggests that there is a long term side effects. Employees working in this paint company have been exposed to the substances for years,. Therefore, there is a possibility that the substances have accumulated to harmful …show more content…
One of the steps that ought to be taken is to introduce the rotational working program where employees working in highly contaminated departments can be shifted to less harmful positions. Under this precautionary measure, employees will be less exposed to the harmful substance. This will ensure that the employees are exposed to the harmful substances at a shorter period of time. Therefore, there will be no room for the substance to accumulate to toxic levels in the body systems. This is an example of a passive precautionary measure since the working environment is manipulated. In this case, the health occupational officer will manipulate the working environment of the employees to provide healthier human resources. The limitation that might arise from this measure will be the difficulty associated with job specializations. The specific duties may require specific experts; thus, discouraging any rotation. Also, employees working in safer job position may not accept the new arrangement as it will endanger that their
Section 8 of the Safety, Health and Welfare at Work Act (2005) puts the onus on the employer to ensure systems of work that are planned, organised, performed, maintained and revised as appropriate so as to be, so far as is reasonably practicable, safe and without risk to health. Section 19 of the Act requires the employer to conduct a risk assessment of work activities and Schedule 3 of the Act provides the general principles of prevention to ensure the safety of employees in the workplace.
OSHA regulations give full disclosure to employees about workplace hazards. Businesses that produce or import chemicals of any sort must review the dangers associated with these chemicals and have them labeled accordingly. They must also prepare material safety data sheets to go with any delivered chemicals. This will describe technical information as well as hazardous effects from exposure and the appropriate protective measures. Any employees wh...
Internal validity, unlike external and construct validity, deals with causal relationships. In other words, the question is whether any additional research that is found is actually associated with the study that is being conducted. The question, again, is whether we can be confident that the outcome of the study is a result of the experiment itself. What this means is that internal validity is the extent to which a change in a given variable is caused by the change in another variable.
However, both characteristics of reliability and validity are important and can be used in many studies, such as the self-rating and other- ratings of daily behavior. Reliability refers to the internal consistency, inter-rater reliability, test-retest, and standardized scoring. In other words reliability means that study scores have to be constant with repeatability of the findings. Validity also refers to convergent validity, discriminant validity, and predictive validity. Validity refers to the reliability or credibility of the research. If the findings in a study, reliability and validity are valid they must be reliable.
The end result is that everyone wants to come to work in an environment that is stress free and safe. A business needs to make a concrete commitment to the health and security of its employees. Let’s not wait until it’s too late.
Internal validity of a research design is extremely important for the interpretation of results. There are various threats to internal validity in single-case designs (SCD) that Kratochwill (2010) discusses. Three threats of internal validity include selection, history, and maturation. Selection refers to the participants selected for the study. If the participants characteristics are very different than it may affect the internal validity.
A researcher uses an experiment to scientifically test out a hypothesis. In an experiment there are many different factors that are involved. There is the independent variable, which is the cause, it is the one that is being manipulated, and the dependent variable, which is the effect, is the response. When conducting a experiment it is important to make sure that the only thing than can affect the dependent variable is the independent variable. This is known as internal validity. Using random assignment to separate the participants into groups helps eliminate any outside factors, and creates an equal chance for all participants to be apart of the experimental conditions. There are many pros and cons to this type of method. The experimental method creates a strong control of the variables involved in the experiment, which allows an easier determination on cause and effect. If needed, it is fairly easy to replicate an experiment and is less time consuming than other research methods. However there are many downfalls as well. When conducting an experiment the setting of where the experiment is taking place is more artificial which may cause certain behaviors that wouldn’t occur in real life. This is known as external validity, which is the measure of how much the results of a study can be generalized and used in different situations, and people. To improve external validity cover stories are created when conducting experiments so the participants are not aware of what is really going on, or experiments are done in a natural setting as opposed to in a laboratory. However, this creates less control over confounding variables that can affect the experiment, which can create bias results (Aronson,
I found it very interesting when talking about experimental research how important validity is. There were two types internal validity and external validity. Internal was more about manipulation/controlling and removing any influence of extraneous variables. By doing so the goal is to be assured that any observed differences between groups in the study is attributed only be differences in the independent variable (e.g., treatment, intervention, and instruction) and no other factors. So, my understanding of this concept is basically understanding and verifying that the research was done right. I was wondering if anyone else got the same conclusion and if there are any other important parts to my understanding of internal validity that I am
Introduction Canadian health and safety legislation requires companies and organizations to make a commitment towards occupational health and safety. Maintaining a safe workplace environment has numerous benefits. A safe work environment can boost employee morale, increase productivity, and improve job satisfaction. For companies and organizations, these benefits can lead to less turnover and increased employee retention. They can also reduce absenteeism while improving the culture and image of a company or organization.
The term ‘occupational health and safety’ (often abbreviated to OHS), is used describe work practices that will keep employees safe. The absence of OHS can be detrimental to a company and its workers alike, as there is a high risk of serious injury. Safety on many worksites must be the top priority for any corporation. Though at our walk-around of Juggernaut Industries, we noticed it wasn’t monitored at all. The following is a list of possible effects and laws that will remind you of the consequences.
Employers have a legal obligation to inform employees about safety and health standards that apply to their workplace. Employers must establish a written, comprehensive hazard communication program to ensure that employees who work with or near hazardous materials...
The World Health Organization specifies that the work environment is an important aspect in the recruitment and retention of health professionals, and the characteristics of the workplace directly, and indirectly affect the quality of care ( Wiskow et al., 2010). Moos
It starts from OSH policy and objective of an company/organization. The OSHMS aim can be achieve if employees implementing and practicing what they have learned from the programmes conducted by their management. The OSH programmes like personal protective equipment, first aid, fire preventive plan, incident/accident investigation, hazard identification and many more are playing an important role to achieve the OSHMS’s aim. The management’s commitment towards safety and health like organizing training and education is resulting in raises the employees awareness on work place safety and health and employees’ involvement to success the safety and health programmes. To enhance the OSHMS, preventive and corrective action and continual improvement are playing an important role. So that the company/organization is keep moving forward successfully in achieving occupational safety and health management system’s

Besides, the principles also indicate the management care about employees. Principles of safety and health act as a starting point for planning and organising the OSH program. The ways of control risk at workplace should be executed based on the hierarchy of controls from the most effective to the least effective. The most effective ways for reducing hazards extend is by elimination and substitution. The engineering controls are covering redesign, isolation, automation, absorption and dilution which are effective ways.
