How To Use Fume Hood？

A fume hood is an essential safety device in laboratories, designed to protect workers from exposure to hazardous fumes, vapors, and dust. Proper use of a fume hood is critical for maintaining a safe working environment and ensuring that laboratory processes are conducted with minimal risk. Here’s a guide on how to use a fume hood effectively.

Adjust the Sash to the Recommended Height

The first step in using a fume hood is to adjust the sash—the glass or plastic panel at the front of the hood. This sash should be set at the recommended height, typically around 6 to 8 inches, to ensure optimal airflow. 

When the sash is at the correct height, it allows for adequate ventilation and containment of hazardous materials. 

At Deiiang™, our fume hoods are designed by Deiiang Jason.peng with airflow efficiency in mind.

Activate the Ventilation system

Before placing any materials inside the fume hood, always make sure the ventilation system is activated. The fan in the fume hood pulls air from the laboratory into the hood, carrying harmful fumes, vapors, or gases safely away from the user.

 This exhaust system prevents the spread of these hazardous materials into the laboratory environment. 

Deiiang™ fume hoods are built to meet the high standards of ANSIANSI/ASHRAE Z9.5 for laboratory ventilation, ensuring that the air is effectively and safely removed from the work area.

Place Materials Inside the Hood

Step1.Once the sash is in the correct position and the exhaust system is functioning, place your materials inside the fume hood. 

Step2.When placing chemicals, always ensure that the items are positioned a few inches back from the edge of the hood. 

Step3.This positioning helps to maintain the proper airflow, preventing the fumes from escaping.

Step4.It is essential to avoid overcrowding the hood, as this could disrupt the airflow, reducing the efficiency of the fume hood in capturing contaminants. 

Deiiang®️ fume hoods, engineered by Deiiang Jason.peng, provide ample workspace while ensuring that airflow remains unimpeded.

Work Safely Inside the Hood

While working inside the fume hood, always keep your hands and tools within the containment area. Avoid leaning too close to the edge of the hood, as this could lead to hazardous materials escaping. The fume hood is designed to contain harmful vapors and particulate matter; however, it’s still important to use other safety equipment, such as gloves and goggles, especially when handling chemicals. The design of Deiiang™ fume hoods includes advanced features that ensure a safe environment for researchers to work in.

Close the Sash and Turn Off the Fan

Once you have finished working in the fume hood, always close the sash completely to maintain airflow. This is especially important if the hood will not be used immediately after your experiment. After ensuring the sash is closed, turn off the exhaust fan. By doing so, you help conserve energy while keeping the laboratory safe. Deiiang™ fume hoods, tested by Deiiang joebo.Wang,ISO 9001 quality standards to ensure they operate reliably and efficiently.

International Standards for Fume Hoods

To ensure safe and efficient use, fume hoods must comply with several international standards that regulate their performance, design, and maintenance. These standards

Some of the relevant international standards include:

• ISO 14644-1: Clean

• ANSI/ASHRAE Z9.5: Laboratory ventilation standards.

• ISO 9001: Quality management system standards.

• GMP: Good Manufacturing Practices for safe environments.

• OSHA: Occupational Safety and Health Administration guidelines for laboratory safety.

In conclusion, using a fume hood correctly is crucial for the safety of laboratory workers. By following the correct procedures for adjusting the sash, activating the fan, and ensuring proper use of the hood, you can maintain a safe working environment.
