Risk Assessment & Hazard Identification Flashcards

What is the primary purpose of risk assessment in workplace safety?

Answer: To identify and control workplace hazards

The primary purpose of risk assessment in workplace safety is to proactively identify potential hazards that could cause harm to employees or others. Once identified, the assessment process evaluates the risks associated with these hazards and determines appropriate control measures to eliminate or reduce them. This systematic approach is fundamental to preventing accidents and occupational illnesses, creating a safer working environment.

Which of the following best defines a hazard?

Answer: Any source that can cause harm

In the context of workplace safety, a hazard is broadly defined as anything with the potential to cause harm, injury, or ill health. This can include substances, equipment, work methods, or environmental conditions. Recognizing and understanding what constitutes a hazard is the first critical step in any risk assessment process, as it allows for proper identification and mitigation.

Which step is NOT part of the risk assessment process?

Answer: Writing a business proposal

The risk assessment process typically involves identifying hazards, determining who might be harmed and how, evaluating the risks, recording findings, and reviewing controls. Writing a business proposal, while important for overall business operations, is not a direct step within the standard methodology for assessing and managing workplace safety risks. Its focus is on business strategy rather than hazard control.

What does the term 'likelihood' refer to in risk assessment?

Answer: The probability of a hazard causing harm

In risk assessment, 'likelihood' refers to the chance or probability that a specific hazard will actually cause harm or an adverse event. It considers factors like how often people are exposed to the hazard, the effectiveness of existing controls, and the nature of the work. Assessing likelihood helps determine the overall risk level when combined with the severity of potential harm.

Why should risk assessments be reviewed regularly?

Answer: To ensure up-to-date and effective risk controls

Risk assessments are not static documents; they must be reviewed regularly because workplace conditions, equipment, procedures, and personnel can change over time. Regular reviews ensure that identified hazards and their associated risks are still relevant and that the implemented control measures remain effective and appropriate. This continuous process adapts to any new circumstances or information, maintaining a high standard of safety.

Which control measure is most effective according to the hierarchy of controls?

Answer: Eliminating the hazard completely

According to the hierarchy of controls, eliminating the hazard is the most effective control measure because it removes the source of danger entirely. By completely removing the hazard, the risk of harm is eradicated, making it superior to other controls like substitution, engineering controls, administrative controls, or personal protective equipment, which only reduce or manage the risk.

What is the role of a Safety Data Sheet (SDS)?

Answer: To outline chemical hazards and safe handling

A Safety Data Sheet (SDS) is a vital document that provides comprehensive information about a chemical substance. Its primary role is to communicate the hazards associated with the chemical, along with instructions for its safe handling, storage, and emergency procedures. This ensures workers are fully informed and can protect themselves from potential chemical risks.

Which factor is least likely to affect the severity of risk?

Answer: Company revenue

The severity of risk in a safety context is determined by factors directly related to the potential harm and likelihood of an incident. Exposure frequency, the number of workers exposed, and the type of hazard all directly influence how severe an incident could be. Company revenue, however, is a financial metric and has no direct bearing on the physical severity or impact of a safety risk on individuals.

What is the benefit of involving employees in risk assessments?

Answer: It ensures realistic and accepted safety measures

Involving employees in risk assessments is crucial because they possess firsthand knowledge of daily operations and potential hazards. Their practical input leads to the development of more realistic, effective, and practical safety measures. When employees contribute to these measures, they are more likely to accept and adhere to them, fostering a stronger safety culture.
