When considering the hierarchy of control measures, it is essential to evaluate each option in terms of its effectiveness and how deeply it removes the hazard from the workplace.
Option 1: Personal Protective Equipment (PPE). PPE provides a barrier between the worker and the hazard but does not remove the hazard itself. Its effectiveness depends on correct usage, training, fit, and compliance, and it does not eliminate exposure for all workers or scenarios. It is typically considered the last line of defense.
Option 2: Engineering Controls. These are physical changes to the workplace that reduce or isolate exposure, such as guards, ventilation, or process changes. They are highly effective because they reduce or eliminate the hazard at the source, but they may not cover every aspect of a complex operation or may require significant implementation effort before other controls.
Option 3: Elimination. Elimination means removing the hazard entirely from the workplace so that there is no exposure risk at all. This is the most effective control because it completely eliminates the possibility of harm rather than managing or mitigating it. If feasible, elimination achieves the safest outcome because it removes the need to rely on human behavior or subsequent control measures.
Option 4: Administrative Controls. These are policies, procedures, training, rotation, and work-rest cycles designed to reduce risk by changing how work is done. They rely on human performance and compliance, can be less consistent, and may not completely prevent exposure, especially if the hazard is still present in the environment.
In summary, PPE offers protection but depends on correct use; engineering controls reduce exposure but may not be feasible in all cases; elimination removes the hazard entirely and stands as the most effective control when possible; administrative controls rely on behavior and are typically less robust as a sole solution.

What is the least effective way to control a hazard?

Examples of a hazard control along the path:

A 62.9 kg lady is standing on a weighing scale in an elevator as shown in the diagram below. Assume gravitational acceleration = 15 ms-2 Given that the elevator is accelerating upwards at 3.7 ms-2 , determine the magnitude of the normal force on the lady.

An object is fired from ground level at an angle of 31.9 degrees to the horizontal. Taking acceleration due to gravity = 7.65 ms-2 If the initial speed is 5.6 ms-1, how far from the starting point will it hit the ground? Assume air resistance is negligible.

Which of the following equations of motion would be used to calculate the displacement given the initial and final velocities as well as the acceleration?

A 51.8 kg lady is standing on a weighing scale (calibrated to 9.81 ms-2) in an elevator as shown in the diagram below. The scale is then calibrated to 7.67 ms-2 Given that the elevator is accelerating downwards at 2.2 ms-2 , determine the reading on the scale.

An object is fired from ground level at an angle of 39 degrees to the horizontal. Taking acceleration due to gravity = 7.65 ms-2 If the initial speed is 6.8 ms-1, how far from the starting point will it hit the ground? Assume air resistance is negligible.
