Question

Engineering controls are the preferred method of eliminating or controlling hazards. What are the 5 types of engineering controls?

1) Elimination
2) Substitution
3) Redesign
4) Isolation
5) Automation

Answer 1

Engineering controls refer to methods of eliminating or reducing hazards, with the five types being Elimination, Substitution, Redesign, Isolation, and Automation. These controls are critical for maintaining workplace safety and must be designed, maintained, and evaluated regularly.

Step-by-step explanation:

Types of Engineering Controls

Engineering controls are methods implemented to reduce or eliminate hazards in the workplace and environments. These controls are a part of a safety management system and are regarded as the most desirable means of protecting workers. Here are the five types of engineering controls:

Elimination - This involves removing the hazard entirely from the workplace. For example, replacing a hazardous chemical with a non-hazardous one.

1. Substitution - Substituting hazardous materials or machines with less hazardous ones to reduce risk, similar to elimination but often involves replacing an element of the process rather than removing it completely.
2. Redesign - Modifying existing equipment or processes to make them safer. This could involve changing the layout of a workplace to improve ergonomics or prevent accidents.
3. Isolation - Separating the hazard from workers, often through enclosures, barriers, or distance, to limit exposure to the hazard.
4. Automation - Using automated systems to minimize human interaction with hazardous processes or materials, thereby reducing risk.

These engineering controls are integral to ensuring workplace safety, and they must be carefully designed, maintained, and periodically evaluated to ensure their effectiveness.
