CHAPTER 7 CHEMICAL, BIOLOGICAL, AND RADIOLOGICAL DEFENSE/DAMAGE CONTROL LEARNING OBJECTIVES Upon completion of this chapter, you 1. Describe the use of chemical, biological, and radiological (CBR) protective clothing and equipment for each level of Mission Oriented Protective Posture (MOPP). 2. List the procedures for instructing personnel in the correct use of CBR protective clothing and equipment for each level of MOPP. should be able to do the following: 3. 4. 5. Explain the types of risk assessments used to evaluate the appropriate levels of MOPP. Describe the four levels of MOPP and the associated countermeasures. Describe the duties of the duty division damage control petty officer (DCPO). In this chapter we will discuss the use of chemical, biological, and radiological (CBR) protective clothing and equipment for each level of Mission Oriented Protective Posture (MOPP) and the types of risk assessments used to evaluate the appropriate levels of MOPP. In addition we will discuss the duties of the division damage control petty officer (DCPO). MISSION ORIENTED PROTECTIVE POSTURE MOPP procedures are used to establish levels of readiness for a chemical agent attack. The procedures are flexible. They allow the com- manding officer (CO) to adapt the requirements for protective clothing and equipment to the degree of the threat and working conditions at any given time. As an example, personnel doing heavy work in hot weather may suffer heat exhaustion in heavy protective clothing and gas masks. Therefore, unless an attack is actually under way, the CO may relax the protective clothing require- ments to prevent certain injury or sickness from heat. Other examples include personnel who cannot do their work wearing protective gear, those who need to eat or attend to body functions, and those who must meet other requirements not possible in protective clothing. The command decision to implement each level of MOPP must be the result of a risk assessment. RISK ASSESSMENT Risk is defined as the assessed difference between the threat level and the activation of appropriate levels of shipboard countermeasures. The risk of casualties and contamination must be evaluated and weighed against the ability of personnel to perform their duties while being hindered by individual protective equipment and the effects of heat stress. MOPP LEVELS AND ASSOCIATED COUNTERMEASURES The risk of a CBR threat can be categorized into four levels of probability: 1. SUSPECTED. An adversary who has CBR-capable delivery systems within the opera- tions area (OPAREA) presents a suspected threat. Implementation of MOPP- 1 countermeasures is indicated. 7-1
