Why is Industrial Ventilation Important for Manufacturing Workshops?

Manufacturing

The building’s ventilation system is specifically designed to facilitate fresh air intake from the outside while simultaneously expelling the air present within. In most workplace settings, a mechanical airflow system effectively eliminates airborne contaminants ranging from hazardous fumes and gases to dust and vapors. Although all ventilation systems adhere to fundamental principles, specific requirements vary significantly. How these systems manage and mitigate contaminants is contingent upon the system itself and the nature of the workplace.

Aside from providing air, ventilation systems also have other crucial roles that must be considered in a workplace setting. Proper ventilation, which may involve the use of specialized components like industrial hoses, is imperative for maintaining a healthy environment. Specific work activities, such as utilizing chemicals or operating grinding wheels, have the potential to introduce contaminants into the surroundings swiftly. Industrial hoses play a significant role in facilitating the efficient extraction and transport of airborne contaminants, contributing to the overall effectiveness of the ventilation system in promoting a safe and healthy workspace.

Ventilation in Industrial Workplaces

Ventilation is either natural or mechanical, and most workplaces, such as offices, can use both means effectively. However, some are enclosed areas where only mechanical ventilation is possible. They are also useful in controlling the spread of contaminants and ensuring that they are safely exhausted and don’t mix with the outside environment.

The use of grinding wheels means one can be working with dangerous materials and debris, and it is necessary to have a proper ventilation system in place. Grinding wheels create sparks as well, and a well-ventilated place is necessary to keep up with safety standards when working with abrasive wheels.

The Hazards of Working with Abrasive Wheels

Abrasive wheels have two potential hazards to ventilation:

  • Dust and Gas Inhalation: Abrasive wheels spin at dangerous speeds, and are used for grinding, cutting, polishing, sanding, and more. These activities can leave finely ground dust particles, debris, and fragments from the materials in the air. These particles are often small enough to be inhaled, which is a serious hazard to the health of employees. Moreover, solid grinding wheels can produce dangerous gases, and the Hazard Communication Standard classifies them as hazardous chemicals.
  • Sparks and Fire Hazards: During use, abrasive wheels create sparks, which are an ignition source that can potentially cause a fire or even an explosion. It is necessary to keep the surrounding areas well-ventilated and cleaned. While safety measures, Personal Protective Equipment (PPE), and guards are necessary, ventilation and cleanliness should be looked out for as well by both organizations and the employees. 

The Purpose of Industrial Ventilation Systems

Industrial ventilation systems have four basic purposes:

  1. Create an intake/exhaust airflow with a fresh supply of air and exhaustion of contaminated air
  2. Keep temperature and humidity maintained
  3. Reduce the potential for a fire hazard
  4. Remove contaminants from the air in the building

Keeping employees free from the potential exposure to the various hazards that can occur from abrasive wheels is crucial to an industrial ventilation system in a workshop.

The Types of Industrial Ventilation Systems

There are two types of mechanical ventilation systems common across industrial areas:

  1. The Dilution Ventilation System
  2. The Local Exhaust System

The dilution system mixes the contaminated air with clean air to reduce the concentration of the airborne contaminants, while local exhaust systems capture the contaminants and transfer them outside through exhaust ventilation. Each has its distinct benefits and drawbacks, and for a workshop that uses grinding wheels, the latter may be the most effective.

That is because airborne contaminants need to be removed rather than diluted in concentration. Mixing it with clean air will not remove the potentially toxic material. For the particles and debris from grinding wheels, industrial workplaces use local exhaust ventilation hoods.

Local Exhaust Ventilation Hoods

These ventilation hoods are called Local Exhaust Ventilation (LEV) systems. LEV systems prevent workers from being exposed to harmful substances by capturing the airborne contaminants and filtering them out through exhausts.

These systems are especially useful as they are both cost-effective and efficient in removing air contaminants as well as heat. Some LEV systems may also filter the air before exhausting it outside, which can depend on the toxicity of the material itself.

Safety Practices in Grinding Wheel Use

Organizations and employers are responsible for ensuring worker safety when working with grinding wheels. Employees can also be provided with abrasive wheel training as they can have an always-available guide to help them brush up on ventilation concerns and other safety practices.

Proper ventilation can also depend on the design of the building’s ventilation, as well as the LEV systems themselves. Both employees and employers should conduct regular inspections and checks to ensure these systems are working as intended. 

Conclusion

Ventilation systems do more than just create an airflow system. They are crucial for ensuring fire safety and preventing exposure to hazardous substances. In this content piece, we have looked at how ventilation systems are used in abrasive wheel workshops and their importance.
