Free SAC Risk Assessment & Hazard Identification Questions and Answers — Questions and Answers

Question 1: What is the first step in conducting a risk assessment?

Eliminate all risks
Identify hazards (Correct answer)
Create control measures
Write a safety policy

Correct answer: Identify hazards

The first and most crucial step in conducting a risk assessment is to systematically identify all potential hazards in the workplace. A hazard is anything that has the potential to cause harm, such as dangerous machinery, hazardous chemicals, or unsafe work practices. Without accurately identifying these sources of harm, it is impossible to effectively assess the risks they pose or develop appropriate control measures.

Question 2: Which of the following is an example of a physical hazard?

Chemical spill
Loud noise (Correct answer)
Workplace bullying
Pathogen exposure

Correct answer: Loud noise

A physical hazard is an agent, factor, or circumstance that can cause harm through physical contact or exposure, often without necessarily being ingested or absorbed. Loud noise is a clear example of a physical hazard because prolonged exposure can directly lead to hearing damage, stress, and fatigue. Other options like chemical spills, workplace bullying, and pathogen exposure fall under chemical, psychosocial, and biological hazards, respectively.

Question 3: What tool is commonly used to estimate the level of risk?

Flowchart
Audit checklist
Risk matrix (Correct answer)
Control log

Correct answer: Risk matrix

A risk matrix is a widely used tool for estimating the level of risk by combining the likelihood (probability) of a hazardous event occurring with the severity (impact) of its potential consequences. This visual tool allows for a systematic and consistent approach to prioritizing risks. It helps organizations decide which hazards require immediate attention and the most robust control measures.

Question 4: Which category does poor lighting fall under?

Chemical hazard
Biological hazard
Environmental hazard (Correct answer)
Mechanical hazard

Correct answer: Environmental hazard

Poor lighting falls under the category of an environmental hazard. Environmental hazards relate to the physical conditions and surroundings of the workplace that can negatively impact safety and health. Inadequate lighting can lead to eye strain, fatigue, and significantly increase the risk of slips, trips, and falls, thereby directly affecting worker well-being and safety.

Question 5: What is the goal of hazard identification?

To eliminate all risks completely
To reduce insurance costs
To identify potential sources of harm (Correct answer)
To improve staff morale

Correct answer: To identify potential sources of harm

The primary goal of hazard identification is to systematically pinpoint and document all potential sources of harm or adverse health effects within the workplace. This proactive step is fundamental for understanding what could go wrong before an incident occurs. By recognizing what might cause injury or illness, organizations can lay the groundwork for effective risk assessment and the development of control measures.

Question 6: When should risk assessments be reviewed?

Only after an incident
Every 5 years
Before staff evaluations
Regularly and when changes occur (Correct answer)

Correct answer: Regularly and when changes occur

Risk assessments are dynamic documents that must be reviewed regularly to ensure their continued accuracy and effectiveness. Furthermore, they should always be reviewed whenever significant changes occur in the workplace, such as the introduction of new equipment, processes, substances, or following an incident. This ensures that new or altered risks are accounted for, maintaining continuous safety improvement.

Question 7: Which term describes the chance that a hazard will cause harm?

Risk (Correct answer)
Exposure
Probability
Impact

Correct answer: Risk

In safety management, 'risk' is defined as the combination of the likelihood (or probability) of a hazardous event occurring and the severity of the harm or consequences that could result. It quantifies the potential for a hazard to cause injury, illness, or damage. Understanding risk involves evaluating both how likely something is to happen and how bad it could be if it does.

Question 8: What is the 'hierarchy of control' used for?

To increase reporting efficiency
To guide hazard communication
To determine training needs
To prioritize control strategies (Correct answer)

Correct answer: To prioritize control strategies

The 'hierarchy of control' is a systematic approach used in occupational health and safety to prioritize different types of control measures for hazards, from the most effective to the least effective. It typically includes elimination, substitution, engineering controls, administrative controls, and personal protective equipment (PPE). This hierarchy guides safety professionals in selecting the most robust and sustainable solutions to mitigate risks.

Question 9: Which of the following is a proactive measure in hazard identification?

Waiting for accidents to happen
Investigating past incidents
Conducting safety audits (Correct answer)
Ignoring minor hazards

Correct answer: Conducting safety audits

Conducting safety audits is a proactive measure in hazard identification because it involves systematically examining the workplace, processes, and safety management system to identify potential hazards and non-compliance *before* incidents occur. Unlike investigating past incidents, which is reactive, audits aim to prevent future harm by identifying weaknesses and areas for improvement in advance. This helps to maintain a safe working environment.
