Are You in the Market for a Fume Hood?

By

One of the primary safety devices in laboratories where chemicals are used is the laboratory fume hood. It allows a researcher to work with—but not be exposed to— materials that create toxic fumes or particles when it is properly installed and maintained.

Top 6 Questions You Should Ask When Buying a Fume Hood

1. Can your lab go ductless? Ductless hoods are a viable solution for most routine laboratory applications.

2. What is the hood constructed from and how is it constructed? Will the chemicals you use attack, degrade or physically alter the material of the hood?

3. What types of safety controls are included in the base cost of the unit?

4. Has the manufacturer/distributor gone through a thorough application review process? Does the suggested filtration make sense?

5. How hard is installation? Will there be a future/potential need to move the hood after initial installation? Should the hood be portable?

6. What are the capital, installation and operational costs? From the lab manager’s perspective, capital costs are but a fraction of the overall budget.

Quit Micromanaging!

The slogan of the micromanager may well be “If you want something done right, do it yourself.” However, “Micromanagement stifles initiative and kills motivation,” according to a very successful manager, World War II General George S. Patton. Despite this, many of us have worked for micromanagers and some of us (this author included) have even been micromanagers. Why do people micromanage? How can micromanagers change their ways?

Optimizing Laboratory Exhaust Systems

The creation of sustainable, high-performance and efficient buildings is growing in importance for companies and governments around the world for both economic and environmental reasons. In particular, laboratories are the focus of many of these reduction efforts as they are some of the largest consumers of energy due to the specialized equipment and ventilation systems required for safety and compliance.
