15、th Exposure Control 1.1. Overview. 1.1.1. Effectively anticipating, identifying and assessing Occupational and Environmental Health (OEH) threats enables the identification and implementation of controls necessary to eliminate or mitigate threats from hazardous OEH exposures. When determining OEH th
16、reat control options, it is imperative to follow the OEH health risk assessment guidelines outlined in AFMANs 48-153, Health Risk Assessment and 48-154, Occupational and Environmental Health Site Assessment. Figure 1.1 outlines the Health Risk Assessment (HRA) and Health Risk Management (HRM) relati
17、onship. This manual focuses on the control portion of HRA/HRM (highlighted in Figure 1.1). 1.1.2. A health threat, as defined in AFMAN 48-153, is a potential or actual condition that can cause short or long-term injury, illness, or death to personnel. Routine and special assessments are conducted in
18、 accordance with AFI 48-145, Air Force Occupational and Environmental Health Program, to identify and assess OEH threats. 1.1.3. A health risk is the combination of an identified health threat and the vulnerability of exposure route completion to the population at risk. Health risks associated with
19、chemical, biological, radiological, nuclear and physical threat exposure(s) may be long-term (chronic) or short-term (acute) and may be reversible or irreversible. Identifying the extent to which individual factors contribute to an OEH threat exposure is critical in the determination of exposure con
20、trols. The primary factors that can affect the intensity of an OEH exposure are: 1.1.3.1. Threat source (e.g. hazardous material used in an industrial process, emissions from an open burn pit, etc.) 1.1.3.2. Route of exposure (inhalation, ingestion, absorption, contact, whole body exposure) 1.1.3.3.
21、 Work patterns/practices 1.1.3.4. Concentration 1.1.3.5. Frequency and duration of exposure 1.2. Standards and Exposure Limits. 1.2.1. Occupational and Environmental Exposure Limits (OEEL) are established to protect personnel from OEH threat exposure(s). They apply to occupational and environmental
22、exposures for individuals and/or similar exposure groups (SEG) in a particular Area of Concern (AOC). Bioenvironmental Engineering (BE) can use OEELs to evaluate the effectiveness of established controls and make recommendations to the affected commander on the acceptability of risk from OEH hazard

BE determines the OEEL using Air Force standards (AFIs, AFOSH standard

In the absence of recognized standards, BE should contact USAFSAM/OE for guida

However, the determination of an unacceptable level of exposure to a potential OEH threat and, subsequently, the need for controls will require local BE staff to work with the affected unit commander to effectively apply Operational Risk Management (
28、ORM) principles outlined in AFPD 90-9, Operational Risk Management and AFI 90-901, Operational Risk Management, as well as professional judgment.

30、8 5 Chapter 2 Occupational and Environmental Health Threat Controls 2.1 Controls. OEH controls are any one or a combination of engineering, administrative or personal protective equipment control(s) implemented to eliminate or minimize an OEH threat. OEH threat control options should be considered a
31、ccording to the following priority: 1) engineering, 2) administrative, 3) personal protective equipment (PPE) as shown in Figure 2.1. The implementation of engineering controls should always be considered first. If engineering controls are not feasible or are not completely effective in controlling
32、the OEH threat exposure, administrative controls and/or personal protective equipment (PPE) will be used. The mission or unique situations may dictate the need for adjustments to this priority in order to adequately control the health hazard and/or protect health. Figure 2.1 Priority of OEH Threat C
33、ontrol Selection Engineering Controls Administrative Controls PPE 2.1.1. Engineering Controls. 2.1.1.1. These controls (e.g. local exhaust ventilation, noise barriers, etc.) are used to isolate, enclose, reduce, attenuate or remove health threats from a SEG. Engineering controls focus on the various
34、 sources of threats and should be incorporated during initial design process. However, design changes to existing systems, elimination of processes and/or substitution of less hazardous materials may be required to ensure personnel are provided a workplace free of recognized health threats. 2.1.1.2.
35、 In some situations, engineering controls such as ventilation systems may be required to control fire or explosive hazards. These hazards may present additional risks other than the occupational or environmental health hazards, and the fire department and safety office should be consulted when these
36、 risks may be present. 2.1.2. Administrative Controls. 2.1.2.1. Administrative controls are any procedures or particular set of actions undertaken in order to significantly limit OEH threat exposure. These controls include measures to reduce exposure frequency/duration for a SEG and development of p
37、rocedures directed at controlling exposures to a health threat (e.g. wetting down a surface to reduce the release of particulate matter). Administrative controls can also include instituting restrictions or directives necessary to prevent health threat exposures (e.g. directing base housing occupant
38、s to boil water due to water contamination). Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-6 AFMAN48-155 1 OCTOBER 2008 2.1.2.2. When changing work practices or locations are not feasible or effective solutions to reducing threats, rotating work sc
39、hedules and/or exposure time limitations can be established to maintain exposures below established OEELs. However, personnel rotation shall not be used to control exposures for human carcinogens or when prohibited by a specific federal, state or Air Force standard. 2.1.3. Personal Protective Equipm
40、ent (PPE). 2.1.3.1. PPE creates a physical barrier between personnel and the OEH threat (e.g. respiratory protection, hearing protection, and protective clothing). It prevents the OEH threat from completing its exposure route. Identification of the threat, potential routes of exposure, and the effec
41、tiveness of a specific protective material in providing a barrier to the threat are the key factors in the PPE selection process. 2.1.3.2. The amount of protection provided by PPE is specific to the protective equipment and threat. For example, protective equipment materials, i.e., rubber gloves, th
42、at protect well against some hazardous substances may protect poorly, or not at all, against others. In order to provide effective protection from identified threats, ensure the protective capabilities of the PPE, in relation to the specific health threat, are considered in the selection process. 2.
43、2. Control Determination. 2.2.1. BE will determine and recommend which controls (engineering, administrative, and/or PPE) are appropriate to reduce hazardous exposures to acceptable levels. Commanders will decide whether or not to implement recommended controls based on mission requirements. The fol
44、lowing paragraphs and tables illustrate examples of control determination. Note the examples are very similar to those used in AFMAN 48-154, Occupational and Environmental Health Site Assessment. These examples were chosen deliberately to help connect this document with companion documents. 2.2.2. H
