Poster Lavorare in modo Sicuro con le Cappe Chimiche da Laboratorio

Working Safely with Laboratory Fume Hoods

• Ensure the exhaust is operating berfore commencing work
• Use approriate personal protective equipment
• Keep your head outside of the hood
• Work as far into the hood as possible and with slow deliberate movements
• If a potential for explosion exists, a blast shield should be utilized
• If a combination sash is installed, do not open the vertical and horizontal sashes simultaneously
• Do not remove airfoil or baffles as they aid the hood's airflow
• Do not use the hood as a storage area - items can affect airflow and interfere with containment
• Do not use the hood's sink for waste disposal
• Do not let chemicals evaporate in the hood as a means of disposal
• Do not leave uncapped bottles of chemicals or waste in the hood
• If performance is suspected, or an airflow alarm is triggered (if installed), terminate usage, close the sash completely and cease work
• Do not use perchloric acid in a conventional fume hood - explosive perchlorate salts could accumulate in the exhaust system
• Minimize external airflow disturbances including foot traffic
• Perform routine maintenance and certification
