A5) Two out of the four ergonomic factors that should be included in a risk assessment are:Load and centre of gravityTask and use the large leg musclesEnvironment and individual capabilityLoad and equipment used

The question seems to be asking for two out of four ergonomic factors that should be included in a risk assessment. From the options provided, the following pairs could be considered:

1. Load and centre of gravity: This refers to the weight of the object being handled and its distribution. An uneven load or one that is too heavy can increase the risk of injury.

2. Task and use of large leg muscles: This refers to the nature of the task being performed and the physical effort required. Tasks that require the use of large leg muscles, such as lifting, can be more physically demanding and potentially hazardous.

3. Environment and individual capability: This refers to the conditions in which the task is being performed and the physical ability of the individual. Factors such as temperature, lighting, and noise can affect performance and safety. Similarly, an individual's physical strength, fitness, and health can affect their ability to safely perform a task.

4. Load and equipment used: This refers to the weight of the object being handled and the tools or equipment used. The use of inappropriate or faulty equipment can increase the risk of injury.

Each pair of factors is important to consider in a risk assessment to ensure the safety and well-being of individuals in the workplace.
