OSHA 30 Hour Construction Program Practice Test

What is hydro-blasting?

1. A vacuum cleaning technique

2. A method of using high pressure water with or without abrasives

3. A form of air blasting

4. A type of chemical cleaning

The correct answer is: A method of using high pressure water with or without abrasives

Hydro-blasting is defined as a method that utilizes high-pressure water, which can be combined with abrasives, to clean surfaces or remove contaminants. This technique is particularly effective for stripping paint, cleaning industrial equipment, and preparing surfaces for new coatings. The ability to adjust the pressure and incorporate abrasives enhances the effectiveness of the cleaning process, making it suitable for a variety of applications in construction and maintenance tasks. Understanding hydro-blasting as a high-pressure water method highlights its efficiency and the fundamental aspects of its operation. This distinguishes it from other methods, such as vacuum techniques, air blasting, or chemical cleaning, which rely on different principles and materials for their cleaning processes. Hydro-blasting stands out for its capability to tackle tough jobs where other cleaning methods may fall short.
