Final answer:
While a supervisor can serve as a safety observer, conflicts of interest and potential bias should be considered. Clear criteria and multiple observers can help mitigate observer bias. The selection of a safety observer should prioritize qualifications and effectiveness.
Step-by-step explanation:
According to workplace safety guidelines, a safety observer may be required depending on the task being performed. Their role is to ensure that the task is being carried out safely and to intervene if any unsafe actions or conditions arise. While a supervisor can serve as a safety observer in some cases, it is important to consider potential conflicts of interest. A supervisor may prioritize productivity or other objectives over safety, which could compromise the effectiveness of their observation.
Observer bias is another concern in observational research. This refers to the potential for observers to have unconscious biases that influence their observations. To mitigate this, it is recommended to establish clear criteria for recording behaviors and to have multiple observers compare their observations for consistency.
Ultimately, the selection of a safety observer should be based on their qualifications and ability to effectively carry out the role, ensuring the well-being of individuals involved in the task.
