Point extraction is a vital component in modern workshop environments that play a crucial role in worker health. By effectively reducing smoke gases and toxic particles in the air, these systems contribute to a safer and healthier workplace. But how are point extraction directly linked to better health, and why are they so important in workshops that handle hazardous materials?
What is point extraction and how does it work?
Point extraction, also known as local extraction, are systems designed to remove contaminants directly at the source before they spread in the work environment. These systems typically consist of fans, filters, and exhaust hoods that are placed near the point of emission of pollutants, such as welding stations. By sucking in air and pollutants efficiently and directly where they occur, point extraction prevents harmful substances from being spread and inhaled by workers.
The development of point- and welding fume extraction systems in industrial environments
Before point extraction became standard, workers in industrial and workshop environments were often exposed to dangerous levels of fumes and particulates, leading to higher incidences of occupational diseases such as asthma and various forms of lung cancer. With growing awareness of these risks in the second half of the 20th century, the implementation of point extraction and other ventilation solutions began to become more common to meet occupational health and safety requirements and protect workers.
Areas of use for the extractor
Point extraction is particularly common in workshops and industrial environments where welding, grinding, painting, and handling of chemicals occur. These environments generate high levels of fumes, fumes and fine dust that can be harmful if inhaled. By installing point extraction directly at these workstations, the spread of pollutants can be effectively controlled.
Types of fume/point extractions and their specific uses
There are several different types of point extraction, each adapted for specific areas of use:
Mobile extraction unit
Perfect for workplaces where tasks vary in position.
Stationary extraction systems
Used where work processes are stationary and continuous.
Submersible arms
Flexible and can be positioned close to the contamination source, often used in welding applications.

Risks with smoke gases and particles
The particles and gases generated in workshops can be extremely dangerous. For example, welding fumes may contain substances such as nickel and chromium, which are known carcinogens. Regular exposure without adequate ventilation can lead to serious health problems, including chronic respiratory diseases and cancer.
Checklist for improved safety in workshops
In order to effectively raise the safety standard in workshops, it is crucial that workshop management and staff are proactive and aware of the risks that exist and the measures that can be taken. Here is a detailed review and expansion of recommended security measures:
Risk assessment
A thorough risk assessment is the first step towards a safer work environment. It should include a detailed analysis of all work processes to identify which generate harmful particles or gases. An inventory of existing equipment is also critical to evaluate whether the existing equipment and its point extraction are sufficient or need to be upgraded. It is important to include feedback from employees who work daily near sources of pollution, to get a comprehensive picture of the risks. Read more on Byggteknik.org
Installation of adequate point extraction
Each workstation should be individually evaluated to ensure that they are equipped with a fume extractor that corresponds to the specific level of contamination and the type of work being performed. The point extraction systems should be designed and configured so that they do not interfere with normal work processes, while effectively removing hazardous substances. It is also critical to use qualified technicians for the installation to ensure that the systems function properly and are optimized for maximum efficiency.
Regular maintenance
A regular maintenance schedule based on the manufacturer’s recommendations and internal safety protocols should be established. It is important to keep a log book in which all maintenance is documented, including the date, actions performed and the name of the person who performed the maintenance work. A policy for immediate action when failure or reduced efficiency is detected in the dust extraction system is also necessary.
Training of personnel
Regular and updated training programs covering the use of fume extraction, the risks of exposure to various contaminants and the importance of personal protective equipment should be implemented. It is also valuable to include practical demonstrations and interactive sessions to better anchor the knowledge of security procedures. Education on how to act in a pollution-related emergency is essential.
Use of personal protective equipment
Protective equipment adapted to the specific risks in each unique work environment should be provided. All personal protective equipment should be regularly inspected for damage and replaced if necessary. It is also important to train the staff in how to use the protective equipment correctly to guarantee optimal protection.
Conclusion – Point extraction in a workshop environment
The implementation of effective point extraction systems in workshops is not only a matter of complying with laws and regulations; it is a critical investment in the health and well-being of workers. By reducing exposure to hazardous fumes and particulates, companies can create a safer and more productive work environment.
