Work rules

The observance of work rules ensures a minimum of operational safety when
handling the biological safety cabinet.
Before starting an operation:
• Take off jewelry.
• Put on required personal protective gear, e.g. hand, face, or body protection.
• Clean and disinfect sample chamber surfaces at regular intervals.
During operation:
• Place samples only within the defined work area of the workplate.
• Do not place unnecessary items into the sample chamber.
• Use only disinfected and cleaned accessories for the work process.
• Do not cause air turbulence by quick hand, arm or body movement in the
sample chamber or in front of the work opening.
• Do not place accessories into the sample chamber that cause air turbulence
or emit excessive heat.
• Do not block air circulation at the ventilation slots of the workplate.
Sitting posture during work:
Fig. 15: To prevent risks to health, a height-adjustable working
chair with an adjustable seat back should be used during
extended work periods at the biological safety cabinet.
A When the forearm rests on the armrest, is should be in a
nearly horizontal position.
B When the upper leg is in a horizontal position, the angle
between upper and lower leg should exceed 90°.
To ensure a compensation between floor and sitting height, a
footrest (DIN 4556) should be used. The minimal effective
surface of the footrest should be 45 x 35 cm.
C The slope should be adjustable within a range of 5° to 15°.
D The adjustable height should extend to a minimum of 11 cm
above the floor.
After finishing an operation:
