It is good that you have posted a safety presentation on Centrifuge
for the benefit of viewers.
1.0 As you are aware there are different types of centrifuges
top driven , bottom driven, belt driven , direct driven etc
You could have mentioned the one you have referred.
2.0 Centrifuges are found in many locations say a clinical
laboratory, a research lab, small scale industry, big industry etc
You could have specified for what application the referred
centrifuge is used.
3.0 Centrifuging operations can be conducted for a simple
separation of slurry or special applications like what you
have mentioned Using Nitrogen. Since an inert atmosphere
is specified in your presentation you could have also
mentioned why you need an
inert atmosphere. This will provide process safety awareness
to the viewer.
4.0 In the third and fourth slide, the last line is the same. Is it correct?
5.0 What is purpose of a wrist band safety aspect ?
Pl explain for the benefit of viewers.
6.0 All the slides seem to have been made in a hurry.
7.0 Oxygen level monitoring is not required for all types of Centrifuging.
Please mention the specific safety
aspect for the application you have mentioned.
8.0 It is mentioned that vent is connected to a catch pit.
Is the catch pit under vacuum?
9.0 Please mention the reason for providing a flame arrester
in the catch pit. What is the safety reason for the same?
That is mention the explosive gas Or combustible material
in your case.
10.0 The DOs are more than DONTs. Please see if it is
necessary to add more of DONTs.
11.0 A simple sketch showing what is to be centrifuged, the drive
arrangement, the outputs, catch pit, flame arrester, Nitrogen
source,basic Instrumentation etc would help the viewers
understand your system and safety aspects better.
Thanks for the initiative taken to share the posting.

A wrist band is used for the ESD(electric static discharge) of who is working in centrifuge room.this is the preventive measure for generating
static electricity in human body/activity.Mostly bulk production plants using centrifuges for material drying in that condition we should maintain the inert atmosphere is the safe mode of operation.

Thank you for your feedback.
I am a Chemical Engineer with experience in areas of Manufacturing and
Projects, besides many others related to Heavy Industries.
My questions addressed to Mr GDV Prasad were with a view of
knowing more about safety related issues, pertaining to Centrifuge operations.
