Sandblasting Rooms: A Guide to Proper Design

15 Mar 2023, 22:24 GMT+10

Sandblasting is a popular method for cleaning and preparing surfaces for painting, coating, or other treatments. However, due to the nature of the process, it can also be dangerous if not properly contained. Equipment like sandblasting rooms helps in this process. This guide will cover the significance of good sand blasting chamber design and best practices for safe use.

Benefits of custom-engineered rooms:

Custom-engineered rooms offer several benefits over prefabricated solutions.

  • One of the main benefits is that they are tailored to the specific needs of the application and environment. This feature allows for optimal performance and efficiency, as well as a higher level of safety.
  • Another benefit of custom-engineered rooms is that they meet specific regulatory requirements and industry standards. These requirements can include compliance with OSHA regulations, NFPA guidelines, and other safety and health regulations.
  • In addition, custom-engineered rooms integrate with existing systems and equipment. It has ventilation systems, lighting, power, and other infrastructure. This feature allows for seamless integration and can result in cost savings and improved performance.
  • Custom-engineered rooms can be flexible and adaptable. It can include expanding or modifying the space as needed and incorporating new technologies and equipment as they become available.
  • Finally, custom-engineered rooms can be aesthetically pleasing and visually appealing. It can include using high-quality materials, finishes, and design elements. This feature can be significant in environments where the room will be visible to customers or clients.

Components of a sandblasting room:

Blast room enclosure:

A blast room enclosure is the main structure of the sandblasting rooms, and it typically includes walls, a ceiling, and a floor. This chamber contains the blasting process and prevents dust and debris from escaping. It also provides safety to the operator.

Dust collection:

A dust collection system captures the dust and debris created during blasting. It typically includes a fan, ductwork, and a dust collector or filter system. The dust collection system helps keep the blasting room air clean and prevents the dust from spreading to other areas.

Filtration System:

A filtration system removes the dust and debris from the blasting room, helping keep the air clean and safe for workers. It typically includes high-efficiency filters.

Media Storage Hopper:

A media storage Hopper is a container used to store the abrasive media (such as glass beads) used in the blasting process. The hopper feeds the media into the blasting equipment. The storage hopper also helps to control the media flow and regulate the amount of abrasive used during the blasting process.

Design Considerations

When choosing a sandblasting room design, there are several important considerations to keep in mind. These include:

Size and shape:

The size and shape of the room will depend on the size of the sandblasted items and the number of operators working at one time.


Proper ventilation is crucial for maintaining a safe working environment. This feature includes general ventilation to remove dust and debris from the air and local exhaust ventilation to capture dust and debris at the source.


Adequate lighting is necessary for safe operation and proper visibility. This feature includes general lighting to illuminate the entire room and task lighting to provide additional visibility for specific areas or tasks.

Safety features:

Safety features, such as emergency shut-off switches, fire suppression systems, and eye wash stations, should be included in the room's design to ensure operators' safety in an emergency.

Take Away:

It would be beneficial if you consulted with a professional when designing and setting up a sandblasting room to meet all safety and regulatory requirements. A professional can also guide the best equipment and materials and assist with the room's installation and maintenance. Additionally, you can conduct regular safety inspections and training to ensure the safe and efficient use of the sandblasting room.
