E. Storage Arrangement. Storage aids for compressed gas cylinders should be noncombustible
and should include steel edge protectors, frames and frame supports, separators, battens, and
pallets. Cylinders of compressed gases should not be stored near readily ignitable substances or
combustibles. Precautions should also be taken to ensure that cylinders are not stored near
unprotected platform edges or in other locations where they are likely to be struck by heavy,
moving objects or MHE. Storage temperatures should not exceed 125oF. as measured at the
surface of the cylinder. When stored inside, cylinders should not be stored near exits.

4.15 DoD Storage Type L: Low Hazard Material (General Purpose) Storage
A. Purpose. This area is a general purpose storage area and should be used to store products
that are classified as low hazard (low risk) materials.
B. Hazard Considerations.
1. For purposes of this chapter, it would be impossible to provide a detailed listing of all the
products involved and the rationale for their classification as low hazard material. Low hazard is
generally assigned on the basis of physical and chemical properties of the material and a review
of the constituents listed on the MSDS with consideration being given to the hazard manifested
to personnel and the environment while in storage. Such a decision relies on the professional
judgment and experience of the person reviewing the relevant data and assigning the HCC.
Although not always regulated by DOT for transportation purposes, these materials sometimes
contain constituents that could be hazardous under circumstances other than routine storage and
handling. While these circumstances are considered in the decision process, the primary factor
influencing the classification is how the material is stored within the DoD. Sodium bicarbonate,
