Safe Use of Filtration Equipment

Air filtration equipment is essential in any lab working with biological agents, chemicals, or particles that could impact the health of those handling them. But what does it take to use these tools safely and ensure the lab is protected at all times? Here, we review key practices for effective and safe use of filtration equipment to protect both personnel and samples.

Filtration in laboratories is about more than keeping the air clean. Filtration equipment also prevents cross-contamination between samples, protects workers from inhaling dangerous particles, and ensures that the lab environment meets safety standards. For example, at Cruma, fume hoods like the Plug&Play Range and Classic Range are designed to offer efficient filtration and adapt to the specific needs of modern labs.

Proper installation is the first step to guaranteeing the equipment works as intended. Mistakes here can reduce filtration effectiveness and expose personnel to risks. To avoid problems, make sure the equipment is placed in a suitable location, away from strong air currents that could disrupt airflow.

Filters are the most essential part of filtration equipment, and their performance declines if they’re clogged or worn out. Periodic inspections and timely filter replacement are highly recommended. Some Cruma units, like the ECO2 Range Fume Hood, include high-efficiency filters that help maintain safety without compromising lab air quality.

Filtration equipment requires careful handling, and knowing how to operate it can make a big difference in lab safety. Training personnel ensures that each team member understands the equipment’s operation, safety protocols, and how to respond if there’s a malfunction.

For filtration equipment to work effectively, airflow must be well-calibrated. Laminar flow cabinets, like Cruma’s Vertical Laminar Flow Cabinets, are designed to maintain a constant flow of clean air in a designated area. Any interruption in this flow can reduce filtration effectiveness, exposing the lab to hazardous particles. Regular airflow checks and avoiding obstructions in vents can improve equipment efficiency.

Safety standards play an important role in the selection and use of filtration equipment in the lab. Ensuring that equipment complies with local and international regulations safeguards personnel and maintains the quality of lab work. Cabinets like Biological Safety Class II A2 and H+ Fume Extraction Hood by Cruma are designed to meet high safety standards, providing peace of mind to labs handling biological samples or sensitive chemical substances.

Preventive maintenance is one of the most important practices to keep filtration equipment in good condition. This type of maintenance helps identify problems before they become failures, extending the life of the equipment and ensuring its performance.

1. Equipment Cleaning: Regularly cleaning equipment surfaces and ducts reduces the build-up of dust and other particles that could clog filters.
2. Checking Moving Parts: Ensuring that moving parts, like fans and ducts, function smoothly; any malfunction can reduce filtration efficiency.
3. Periodic Performance Tests: Evaluating filter and airflow performance regularly helps detect early issues and adjust or replace components as needed.

In addition to maintenance, it’s crucial to follow basic practices that ensure the equipment functions optimally and safely.

• Avoid Overloading the Work Area: Cabinets like Precision Weighing Cabinets W-2 are designed for specific spaces. Make sure not to overload the work area, as this could affect airflow and reduce filtration effectiveness.
• Check Operation Indicators: Many modern units include indicators that show filter or airflow status. Checking these indicators regularly allows for early troubleshooting.
• Keep a Clean Work Environment: General lab cleanliness is important for any filtration equipment’s effectiveness. Reducing dust and particles in the environment lowers filter workload and improves air quality.
