Do You Need Customized Planning, Design, or Testing Reports for Local Exhaust Ventilation (LEV) Systems?
According to current occupational safety and health regulations, employers are required to install properly designed enclosed systems, local exhaust ventilation (LEV) systems, and general ventilation systems in the workplace. These systems must be designed by qualified professionals and undergo regular and focused inspections to ensure they function effectively, thereby protecting the health and safety of workers.
When installing a local exhaust ventilation system, the employer must assign or commission professionals certified by the Occupational Safety and Health Administration (OSHA Taiwan) to carry out the design and provide a complete LEV system design report.
At Kennis Engineering Consultants Co., Ltd., our licensed engineers are officially certified by the Taiwan OSHA and are fully qualified to provide the customized services you need.
(Applicable regulations include: Standards for the Prevention of Hazards from Specific Chemical Substances, Regulations on the Prevention of Lead Poisoning, Standards for the Prevention of Dust Hazards, and the Regulations on the Prevention of Organic Solvent Poisoning.)
Why Is It Critical Not to Install LEV Systems Carelessly?
Have you encountered this issue?
Some factories or laboratories have installed exhaust systems, yet workers are still exposed to hazardous gases or airborne particles. Over time, this not only poses serious health risks but also affects productivity, leads to equipment damage, and causes unplanned downtime—a nightmare for any operation.
The root cause?
Poor design and lack of testing.
An effective local exhaust system is not just about installation. We strongly advocate that all systems be:
✅ Designed by certified, professionally trained personnel
✅ Accompanied by a comprehensive design report
✅ Supported with original testing data
✅ Compliant with all relevant legal standards
Only such a well-designed, site-specific system can effectively reduce workers’ exposure to hazardous substances.
What Are the Benefits of Professional LEV Design?
✔️ Resolves issues such as insufficient airflow, incorrect direction, and unsafe operation
✔️ Field-tested under real working conditions—not just theory
✔️ Precise material selection and flow control calculations
✔️ All documentation is archived in detailed reports—ideal for future upgrades or maintenance
Professional Teams Are Limited—Inquire Early!
Qualified and reliable LEV design professionals are rare. If you’re committed to improving workplace health and safety, contact Kennis Engineering Consultants today. Once you experience the difference a safe and efficient exhaust system can make, you’ll know this investment was truly worthwhile.
Legal Obligations
According to Taiwan labor safety regulations:
When workers are required to work in confined spaces with potential health hazards, the employer must install adequate ventilation systems and ensure they operate continuously and effectively. These systems must prevent oxygen deficiency and harmful substance accumulation in the work environment.
Such confirmation and inspection must be performed by designated personnel, and records must be retained for three years.

The purposes of industrial ventilation are mainly as follows
|
Employers shall regularly inspect local exhaust devices, air cleaning devices and blowing and suction type air exchange devices once a year in accordance with the following requirements.
- air cover, tubing and exhaust wear, corrosion, bumps and other damage to the condition and degree.
- Dust accumulation on the tubing or exhauster.
- The lubrication condition of the exhauster.
- The condition of the contact part of the tube.
- The loose condition of the belt connecting the motor and exhauster.
- The ability of suction and exhaust.
- Whether the sampling facilities installed on the discharge pipe are firm, rusty, damaged, collapsed or otherwise impede the safety of the operation.
- Other necessary matters to maintain the performance.
