10 do's and don’ts for successful local exhaust ventilation

Local Exhaust Ventilation (LEV) systems are designed to control and remove hazardous substances from the air, making them an essential component of workplace safety and health. To ensure the success of your LEV system, it's important to follow some key do's and don'ts. Here are 10 do's and don'ts for successful Local Exhaust Ventilation:

Do's:

1. Do identify the hazardous substances that need to be controlled and removed from the air.

2. Do ensure that your LEV system is properly designed to capture the hazardous substances at the source.

3. Do ensure that your LEV system is properly installed and maintained.

4. Do ensure that your LEV system is regularly tested and inspected by a competent person.

5. Do ensure that your LEV system is properly used and maintained by workers.

6. Do train workers on how to properly use the LEV system.

7. Do ensure that your LEV system is properly grounded and bonded to prevent electrostatic discharge.

8. Do ensure that your LEV system is properly sized to handle the volume of air and hazardous substances in your workplace.
