Gloves 

 

We recommend a glove with a longer cuff length for use with the LFGI.  The sleeve and 

“bracelet” system will accommodate almost any commercially available glove but some 

suggestions (this does not constitute product endorsement by GERMFREE) are as follows: 

 

SafeSkin by Kimberly-Clark offers Powder-Free Purple Nitrile Exam gloves in a 12 inch 

cuff. 

 

Chemo Plus, Chemo Bloc T, Chemo Bloc, Chemo Plus Neoprene, Chemo Bloc Nitrile and 

Chemo Bloc Nitrile Plus by Kendall offer a 12 inch cuff.   

 

Microflex offers many cleanroom grade gloves at a 12 inch cuff length, some sterile some 

non. 

 

Alarm 
 

When the low pressure alarm sounds, corrective action must be performed or the unit will 

require shut down to stop the alarm. Alarms are tested at the factory before shipping.  

Dramatic drops in pressure indicating possible containment failure are alarmed.  Alarms will 

sound when operating work area pressures are between –0.05 and +0.05 inches water 

column (w.c.).  Normal work area pressures are 0.1 (+0.025) inches w.c. in either positive or 

negative overall pressures. 

 

Troubleshooting for Alarm Sounding 

Cause

 

Corrective Action

 

Glove Rip/Tear/Removal 

Replace Glove 

Sleeve Rip/Tear/Removal 

Replace Sleeve 

Inner Airlock Door open 

Close Inner Airlock Door 

View Panel not Sealed 

Ensure latches are fastened on view panel 

Pressure Hose Disconnected 

Reconnect small tube between control panel 

and work area 

 

After corrective action is taken, allow 30 seconds for alarm to reset.  Observe the digital 

read-out to ensure that the magnitude of the number is increasing.  If number does not 

increase and alarm continues to sound call your certifier or GERMFREE at 800-888-5357 

for further troubleshooting.
