SAFETY PRECAUTIONS

environments, such as the flight deck, hangar deck, or weather decks. A degree of relief from HERO RF restrictions is obtained by following the command HERO EMCON bill. The HERO EMCON bill depends upon two factors—(1) the amount and type of ordnance that is involved, and (2) a knowledge of the RF environment at locations where presence, handling, and loading occur. The HERO EMCON bill contains a list of all HERO-susceptible and HERO-unsafe ordnance items on board and their allowable RF environmental levels. It also includes a list of all transmitter-antenna combinations on board and their output power. By reducing or securing certain transmitter-antenna combinations, allowable RF environmental levels can be maintained Normally, to ensure that proper conditions are met in a given ordnance-handling situation, two actions are taken; 1. All onboard transmitters are listed. 2. The action each operator is to take when a given HERO EMCON condition is set. For example, in HERO condition 1, a transmitter operator may switch the transmitter to STANDBY. In HERO condition 2, the same operator may restrict transmission to 100 watts, or perhaps there is no transmission restriction at all. The AO is the most important factor in avoiding a HERO-unsafe situation. You determine if an ordnance item is HERO safe, HERO susceptible, or HERO unsafe. Before moving a HERO-unsafe item from an RF-free environment, you must request, through strike operations or ordnance control, the proper HERO condition. You make sure that the ordnance item remains in an RF-free environment until the word has been passed that the proper HERO condition has been set.

List the three HERO ordnance classifications. Q2. Ordnance is HERO safe if it meets what criteria? Q3. Name the environment to which HERO- susceptible and HERO-unsafe ordnance should not be exposed. Q4. What is the HERO EMCON bill? Q5. What information can you find in the local HERO EMCON bill? SAFETY PRECAUTIONS LEARNING OBJECTIVE: Recognize the importance of safety precautions when working with ordnance. Accidents caused by explosives are prevented by preplanning, ordnance training, and carefully handling ordnance. The phrase “The life you save may be your own” is a good one, especially when you handle ordnance. It is your responsibility to make sure that safe, approved practices and procedures are used when you handle ordnance. 11-33
