APPENDIX A. BACKGROUND/RATIONALE
ANNEX 3. NON-SEQUENTIAL SAFETY TESTS
A.3-2 HEALTH HAZARDS (APPENDIX H, ANNEX 2).
Health hazard data is to be collected during the firing safety tests (see Appendix D, Annex 1). The
hazards to be assessed for surface launched munitions are described below.
A.3-2.1 Acoustic Energy (Impulse Noise and Blast Overpressure) (Appendix H, Annex 2,
Paragraph H.2-1).
The weapon firing precipitates the sudden release of gases into the surrounding air, causing a shock
wave or front to be propagated outward from the source. Firing tests are performed to measure
blast overpressure and acoustic noise to determine if the shock wave damages structures and/or
injures personnel. Further information may be found in MIL-STD-1474 and International Standard
ISO 10843: 1997 Acoustics - Methods for the description and physical measurement of single
impulses or series of impulses.
A.3-2.2 Toxic Chemical Substances (Appendix H, Annex 2, Paragraph H.2-2).
Rocket exhaust gases contain toxic chemical substances such as CO, CO2, SO2, NO, NO2, and HCl.
Other harmful chemicals should be considered if determined to be potentially harmful to the
operator. These hazards shall be evaluated with respect to the envisaged operational environment
and on the basis of pertinent national laws and regulations.
A.3-2.3 Radiating Energy (Appendix H, Annex 2, Paragraph H.2-3).
Weapon firings may subject the operator to extreme heat and light exposure. The propulsion unit
radiance may produce permanent or temporary eye damage (i.e., flash blindness). Exposure to heat
during munition launch may cause eye and skin damage.
A.3-2.4 Launch Shock (Recoil) (Appendix H, Annex 2, Paragraph H.2-4).
Shock levels due to weapon firing and recoil may injure the firing crew. The probability of injury
increases with the blast energy of the weapon, proximity of the operator to the weapon, and the
duration of the shock environment.
A.3-2.5 Other Launch Platform Integration Assessments.
Sufficient evidence should be provided to determine whether the launch platform interface and the
munition have adequate structural integrity to withstand the anticipated dynamic loading. For
munition systems following the Analytical S3 Test Approach (see Appendix B, Annex 1), live fire
testing from ground launch stations may be required to provide sufficient evidence of safe
separation, launch/blast effects, and human factors associated with weapon system operation.
