Hazard Identification & Risk Assessment Flashcards

Why is hazard identification critical on a worksite?

Answer: To prevent injuries and manage risks proactively

Hazard identification is the foundational step in any safety management system, especially in environments with lead. By systematically recognizing potential dangers before work begins, contractors can implement appropriate control measures. This proactive approach minimizes the likelihood of accidents, injuries, and health issues, ensuring a safer worksite for everyone.

What is a risk assessment?

Answer: Evaluation of potential hazards' likelihood and impact

A risk assessment is a systematic process of identifying potential hazards, analyzing the likelihood of them occurring, and evaluating the severity of their potential impact. It helps determine which risks are most significant and guides the development of effective control measures. This evaluation allows for informed decision-making to prioritize safety interventions.

Which tool helps in systematically identifying workplace hazards?

Answer: Job Hazard Analysis (JHA)

A Job Hazard Analysis (JHA) is a systematic process used to break down a job into individual steps, identify potential hazards at each step, and determine the safest way to perform the job. This tool helps proactively identify and mitigate risks associated with specific tasks, ensuring that safety controls are integrated into work procedures. It is a key component of a comprehensive safety program.

When should risk assessments be updated?

Answer: Whenever new hazards or changes occur

Risk assessments are dynamic documents that should be reviewed and updated regularly, especially when there are changes to work processes, equipment, or the work environment. New hazards can emerge, or existing risks can change in severity or likelihood. Regularly updating assessments ensures that safety measures remain relevant and effective in protecting workers.

What is the goal of hazard control measures?

Answer: Eliminate or minimize risk

The primary goal of hazard control measures is to protect workers and others from harm by either eliminating the hazard entirely or reducing the risk to an acceptable level. These measures are implemented based on the hierarchy of controls, aiming to prevent incidents and ensure a safe working environment. Effective controls are essential for compliance and worker well-being.

Which is an example of an engineering control for hazard mitigation?

Answer: Installing ventilation systems

Engineering controls are physical changes to the workplace that reduce or eliminate hazards at the source. Installing ventilation systems, such as local exhaust ventilation, effectively removes airborne contaminants like lead dust from the work area. This method is highly effective because it controls the hazard before it can reach workers, making it a preferred control measure over PPE alone.

What is the hierarchy of controls in risk management?

Answer: Structured approach to minimizing risks

The hierarchy of controls is a structured, prioritized approach to managing risks, ranging from the most effective to the least effective. It typically includes elimination, substitution, engineering controls, administrative controls, and personal protective equipment (PPE). Following this hierarchy ensures that the most robust and sustainable risk reduction methods are considered first.

Who is responsible for reporting workplace hazards?

Answer: Everyone on the worksite

Workplace safety is a shared responsibility, and everyone on the worksite, from management to individual workers, plays a crucial role in identifying and reporting hazards. Encouraging all personnel to report concerns creates a culture of safety and allows for prompt action to mitigate risks. This collective vigilance is essential for maintaining a safe working environment.

Why should near-miss incidents be reported?

Answer: They reveal hidden risks and improve safety

Near-miss incidents are events that did not result in injury, illness, or damage but had the potential to do so. Reporting and investigating near misses is vital because they often highlight underlying hazards or deficiencies in safety procedures that could lead to future, more serious incidents. Analyzing near misses provides valuable data to proactively improve safety protocols and prevent actual accidents.
