General Work Practices for Laboratory Hoods
This 1 minute safety training video covers: How to properly utilize local ventilation controls, how to properly select lab hoods, what are the proper working procedures for laboratory hoods.
You already know that the chemical fume hood is one of the most important tools in the lab, but are you aware that a co-worker walking pass the hood can drastically affect how it’ll protect you or moving your hands quickly can put you at risk. A piece of dry ice can remind you how the hood works. When you plan an operation, determine the fume hood if it is required. If so, check the hood for proper operation before you begin, make sure the light is working and that you have a proper airflow. If you’re unsure always use a fume hood and if your lab has incompatible materials always use the correct fume hood for appropriate chemicals. Always check fume hood calibration date. Once you are sure that the hood is working properly, gather all materials in the hood and used personal protective equipment before you begin. As you work draw an imaginary line 6 inches behind the plain of the sash and keep all work behind those line.
