IOSH Assessing Risks 5

Question 1

What is a 'task-based' risk assessment?

Accepted Answer

An assessment focused on the specific hazards and risks associated with a particular work task or activity

Answer

A task-based risk assessment focuses on a specific work activity or task, identifying the particular hazards associated with that task, who could be harmed, and what controls are needed. It is more focused than a general workplace assessment.

Question 2

In a 5×5 risk matrix, what would a score of 25 indicate?

Accepted Answer

The highest possible risk — immediate action required

Answer

In a 5×5 risk matrix (likelihood 1-5 × severity 1-5), a score of 25 represents the maximum risk: almost certain likelihood combined with catastrophic severity. This would require immediate action to eliminate or significantly reduce the risk.

Question 3

What factors should be considered when evaluating the likelihood of harm?

Accepted Answer

Frequency of exposure, number of people exposed, effectiveness of existing controls, and human factors

Answer

When evaluating likelihood, you should consider: how often people are exposed, how many people are exposed, the duration of exposure, the effectiveness of existing controls, human factors (behaviour, competence), and any historical incident data.

Question 4

What is a 'specific' risk assessment?

Accepted Answer

An assessment required by specific regulations, such as COSHH, manual handling or DSE

Answer

Specific risk assessments are required by particular regulations such as COSHH (substances), Manual Handling Operations Regulations, Display Screen Equipment Regulations, and Noise at Work Regulations. They follow specific methodologies set out in those regulations.

Question 5

When should a risk assessment be carried out for a new work activity?

Accepted Answer

Before the work activity begins

Answer

A risk assessment must be carried out before a new work activity begins. This ensures that hazards are identified and appropriate controls are in place before anyone is exposed to the risks.
