A Practical Guide to Working With AFMAN 64-4 (Air Force Manual 64-4)
If you are assigned to a unit that handles ammunition and explosives, or if your job involves environmental compliance around former ordnance areas, you will eventually run into AFMAN 64-4. The full title is Air Force Manual 64-4, and it covers the procedures for handling, storing, and disposing of explosive materials safely. I have spent enough time dealing with inspectors from this manual to know that the document itself is dense, but the actual work is mostly about following the right procedure at the right time. The manual sets out the standards for operating within magazines, conducting ammunition movements, performing safety inspections, and managing explosive incidents. It references both the DoD criteria and Air Force-specific supplements. The most important sections for daily work are the ones dealing with distance requirements, magazine construction standards, and the inspection checklists. Those checklists are what inspectors carry around like a bible when they visit your site. The document is available through the official AF Portal or the e-Publishing site. If your unit has a designated publications librarian, they already know how to pull it. If not, search the AF Portal under "64-4" and download the latest version. Older versions expire quickly and inspectors will flag you for using them.
How It Feels When You Actually Use It on Site
The manual assumes you are working in a controlled environment with trained personnel and proper facilities. That assumption breaks down pretty fast when you are dealing with a temporary storage setup on a forward site or an old ammunition plot that predates modern standards. I ran into this exactly on a rotation where we had to stage limited quantities of munitions in an area that had no approved magazine. The manual clearly states the minimum distance requirements for provisional storage, but it does not give you a simple answer for every terrain scenario. What ended up working for us was calculating distances from the nearest occupied building and from any public way, then documenting the deviations with a written risk assessment signed by the unit commander and the explosive safety officer. That paper trail is the difference between an inspector writing you up and an inspector noting it as a conditional approval. Inspectors almost always check three things first: the current version of the manual, the most recent inspection sign-off, and the inventory records. You can lose points on all three if you are not organized. The inventory section in particular causes problems. If your property book and your actual box count do not match exactly, the inspector will expand their audit, which means they pull every bin, bag, and shelf label until they are satisfied. This process takes most of a morning even under good conditions. Keep the property book updated in real time, not at the end of the month. One entry lag creates a cascade of mismatches. Another issue is the inspection date formatting. Some people write dates in DDMMMYY format, others use MMDDYY. The manual prefers a standard but field practice varies. Just pick one and stick to it across every form in your unit.
A Few Things the Manual Does Not Make Clear
The distance tables in the main body are detailed, but the tables for special hazard scenarios require cross-referencing with other references, especially the Ammunition and Explosives Safety Standards in the DoD system. If you are relying only on AFMAN 64-4 for a complex siting decision, you will miss updates that live in the supporting documents. I learned this the hard way when a revised distance factor for certain incendiary types was not reflected in our local copy. The fix was straightforward once I found the erratum, but tracking those down without someone who knows the reference chain is frustrating. There is also a gap in how the manual handles mixed-storage situations where conventional munitions share a magazine area with certain pyrotechnic items. The guidance points you to a separate annex, but the annex references back to the main body. It is circular if you are trying to make a quick decision. The workaround is to involve the command explosives safety shop early and get their written interpretation rather than guessing from the text alone.

When This Manual Is Not Enough
AFMAN 64-4 is solid for routine operations at established installations. It falls apart a little when you are dealing with non-standard configurations, foreign military sales transfers that involve different handling requirements, or incidents that blur the line between accidental and intentional discovery of ordnance. In those cases, you need to layer in the joint publication on explosive ordnance disposal procedures and the relevant theater-specific guidance. No single manual covers every edge case, and pretending it does is what gets people in trouble. The current version is posted on the e-Publishing website and the AF Portal. Both require a valid CAC or DS Logon. If you are working from a location without secure access, ask your publications manager to print the relevant sections you actually use. Carrying the full manual around is unnecessary and slows you down. Highlight the sections you reference daily, keep a binder with just those pages, and leave the rest in the office file. That keeps the right information visible without burying it under four hundred pages of reference material. The manual is updated periodically. Check the revision history on the title page before you start any major project or audit preparation. A superseded version is an easy way to look unprepared in front of an inspector.
