Control Measures and Equipment

January 10, 2012Slide2

Ventilation

Laboratory ventilation should be not less that six air changes per hour (calculated

)

Work with toxic chemicals that have low air concentration limits, or that have high vapor pressures, should always be done in a

hood

Fume

hoods should provide 70 to 90 linear feet per minute of air flowSlide3

The apparatus inside the hood should be placed on the floor of the hood at least

six inches away from the front edge

Fume hood windows should be lowered at all times

Hoods should never be used as storage areas for chemicals

VentilationSlide4

In the event of fume hood failure:

Immediately stop all work inside the fume hood

If safe to do so, secure or isolate reactions and turn off all equipment being usedIf safe to do so, close all open chemical containers

Close the sash completely

Report the problem immediately
