CESCO - Certified Environmental, Safety and Compliance Officer Risk Assessment and Management Questions and Answers

Question 1

A CESCO is developing a risk assessment for a chemical storage facility. After identifying hazards and analyzing risks, the officer plots each risk on a matrix. What are the two primary axes of this risk matrix?

Accepted Answer

Likelihood and Severity

Answer

A standard risk matrix is a tool used to define the level of risk by considering the likelihood (or probability) of an event occurring against the severity (or consequence) of its impact. This allows for the prioritization of risks.

Question 2

When performing a Job Hazard Analysis (JHA), what is the crucial first step after selecting the job to be analyzed?

Accepted Answer

Breaking the job down into a sequence of steps or tasks.

Answer

The foundational process of a Job Hazard Analysis (JHA) involves observing the job and breaking it down into a sequence of individual steps. Only after documenting these steps can one effectively identify the associated hazards for each part of the job.

Question 3

A manufacturing plant has identified that a solvent used in a cleaning process poses a significant inhalation hazard. According to the NIOSH hierarchy of controls, which of the following actions represents the most effective method for managing this risk?

Accepted Answer

Replacing the hazardous solvent with a non-toxic, water-based cleaner.

Answer

The NIOSH hierarchy of controls ranks risk mitigation strategies from most to least effective. The top levels are Elimination and Substitution. Replacing the hazardous solvent with a safer alternative (Substitution) is more effective than engineering controls (ventilation), administrative controls (training), or PPE (respirators) because it removes the hazard at its source.

Question 4

Which of the following best describes the risk management principle of 'As Low As Reasonably Practicable' (ALARP)?

Accepted Answer

Risks should be reduced until the cost of further reduction is grossly disproportionate to the benefit gained.

Answer

The ALARP principle states that a risk should be reduced to a level that is 'as low as reasonably practicable'. This means that risk reduction measures should be implemented unless the cost, time, or effort involved in doing so would be grossly disproportionate to the safety benefit achieved.

Question 5

During a facility audit, a CESCO identifies a high-risk confined space entry procedure. After implementing engineering controls and updated work practices, a residual risk remains. According to the hierarchy of controls, what is the final layer of protection that should be considered for workers?

Accepted Answer

Personal Protective Equipment (PPE).

Answer

Personal Protective Equipment (PPE) is considered the least effective control in the hierarchy and should be used as the last line of defense after higher-level controls like elimination, substitution, engineering, and administrative controls have been implemented to reduce the risk to the lowest possible level.
