Standard Guide for Handling Hazardous Biological Materials in Liquid Nitrogen
SCOPE
1.1 This guide covers recommended procedures for maintaining and handling hazardous biological materials at liquid nitrogen temperatures.
1.2 This guide covers the safety precautions recommended when handling material stored in liquid nitrogen.
1.3 This guide does not cover the maintenance and handling of hazardous biological materials maintained at cryogenic temperatures in systems other than liquid nitrogen.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
Hazardous biological materials maintained at liquid nitrogen temperatures require special handling
and storage procedures. The penetration of vials by liquid nitrogen during storage can result in
contamination of the nitrogen itself or contamination of personnel resulting from improperly sealed
3,4
vials exploding. Ensuring safe storage conditions and taking precautions during the retrieval of
cultures from liquid nitrogen can help reduce the potential hazards. To avoid the penetration of vials
by liquid nitrogen and resulting hazards, they should be filled to a point that minimizes the air space
in the vial, and they shall be sealed completely. Vials may be examined for leaks by immersing them
in an aqueous methylene blue (0.05%) solution at 4°C.
