Cryogenic Liquid Burns

We have had a couple instances of employees receiving cryogenic burns from improper handling of liquid nitrogen over the past year. Cryogenic liquids such as liquid nitrogen and liquid helium can rapidly freeze human tissue. This tissue destruction results in a cryogenic burn that is very similar to a thermal burn. Please click here to find out more about how to ensure you do not get burned when working with cryogenic liquids.


Centrifuge Dangers


The centrifuge is a common piece of laboratory equipment that has the potential to cause serious injury if not properly used or maintained. Some centrifuges can generate forces of 1,000,000 x g. With the generation of such great force rotor failures can become deadly projectiles. The risk of your centrifuge becoming a safety hazard can be mitigated through proper preventive maintenance and strict adherence to manufacturer procedures and your internal laboratory safety procedures. Please click here to find out more on the proper use and maintenance of your centrifuge which can prevent a rotor failure seen in the picture below.

Newly Revised Chemical Hygiene Plan


Over the past year I have revised the IUPUI Chemical Hygiene Plan. This new revision contains over 100 new pages of text that provide guidance to our laboratory personnel on how to work with hazardous chemicals safely. The OSHA Laboratory Standard requires all laboratory employees to read and understand this plan. I will also make this document available on our web page. Please click here to read the 2012 revision of the IUPUI Chemical Hygiene Plan.

Please Remove Gloves Before Leaving the Laboratory


Although it is standard laboratory practice to remove all personal protective equipment (PPE) prior to exiting the laboratory, we are seeing laboratory personnel in hallways with gloved hands. Please click here to find out why it is important that gloves are removed prior to leaving the laboratory. You will also find a sign that can be posted to remind you to remove your gloves before leaving the laboratory. Please help us maintain a professional image and at the same time keep our public spaces safe and free of contamination.

NEW GxP Training

GxP is an acronym that refers to the regulations established by the United States Food and Drug Administration which are published in the Code of Federal Regulations. Sometimes people refer to the "GCPs" which specifically were created as the rules that govern clinical trials vs. product manufacturing (GMPs) or laboratory regulations (GLPs). If you are conducting research in Indiana University laboratories you need to have an understanding of GxPs. Good Guidance Practices promote the traceability and accountability of data that create an environment conducive to quality research and ensure the integrity of your data. Beginning September 10th GxP training will be offered every month on the second Monday of the month at 11:30 am immediately following Laboratory Safety Training in Lockefield Village Room 4401. You do not need to register for this training. If you are working in a laboratory, you will find the information provided during the training valuable and incorporation of good scientific practices can improve the quality of your research.
