PURPOSE
|
The purpose of Task 207 is to perform and document a Health Hazard Assessment (HHA) to identify health hazards, evaluate proposed hazardous materials, and propose protective measures to reduce the associated risk to a level acceptable to the MA.
| |
TASK DESCRIPTION
|
A HHA shall be performed and documented to identify health hazards and to recommend engineering controls, equipment, and/or protective procedures, to reduce the associated risk to a level acceptable to the MA. An HHA shall also evaluate the hazards and costs due to system components materials, evaluate alternative materials for those components, and recommend materials that reduce the associated risk. Materials will be evaluated if (because of their physical, chemical, or biological characteristics; quantity; or concentrations) they cause or contribute to adverse effects in organisms or off-spring, pose a substantial present or future danger to the environment, or result in damage to or loss of equipment or property during the systems life cycle. Assessments shall include consideration of the generation of hazardous wastes.
| |
A health hazard is an existing or likely condition, inherent to the operation, maintenance, transport or use of materiel, that can cause death, injury, acute or chronic illness, disability, or reduced job performance of personnel by exposure to physiological stresses. Specific health hazards and impacts that shall be considered include:
| |
Chemical hazards (e.g., hazardous materials that are flammable; corrosive; toxic; carcinogens or suspected carcinogens; systemic poisons; asphyxiants, including oxygen deficiencies; respiratory irritants; etc.).
| |
Physical hazards (e.g., acoustical energy, heat or cold stress, ionizing and non-ionizing radiation).
| |
Biological hazards (e.g., bacteria, fungi, etc.)
| |
Ergonomic hazards (e.g., lifting requirements, task saturation, etc.)
| |
Other hazardous, or potentially hazardous, materials that may be formed by the introduction of the system. or by the manufacture, test, maintenance or operation of the system.
| |
The HHA hazardous material evaluation shall:
| |
Identify the hazardous materials by name(s) and stock numbers; the affected system components and processes; the quantity, characteristics, and concentrations of the materials in the system; and source documents relating to the materials.
| |
Determine under which conditions the hazardous materials can release or emit materials in a form that may be inhaled, ingested, absorbed by living organisms, or leached into the environment and if the materials pose a health threat.
| |
Characterize material hazards and determine reference quantities and hazard ratings. Acute health, chronic health, carcinogenic, contact, flammability, reactivity, and environmental hazards will be examined.
| |
Estimate the expected usage rate of each hazardous material for each process or component for the subsystem, total system, and program-wide impact.
| |
Recommend the disposition of each hazardous material identified. If for any scale of operation the reference quantity is exceeded by the estimated usage rate, material substitution or altered processes shall be considered to reduce risks associated with the material hazards while evaluating the impact on program costs.
| |
REPORT REQUIREMENTS
|
The contractor shall prepare a report that contains the results from the work task described by paragraph "TASK DESCRIPTION" above to include the following information:
| |
References
|
A list of source materials used in preparing the report. Include for example, government and contractor reports, standards, criteria, technical manuals and specifications. If references are numerous, put them in a bibliography as an appendix.
| |
System description
|
A brief identification of the system and its purpose. Address significant health hazard issues that are identified later in the report.
| |
Background
|
A description of the system and its intended operation. Include pertinent components or subsystems which contribute most to a health hazard. The identity of the intended users and the type of protective clothing and equipment, if any, available to the user. A summary of the evaluations or assessments performed on system prototypes or developmental models
| |
Identification of health hazard issues
|
A description and discussion of each potential or actual health hazard issue of concern for each subsystem or component.
| |
System breakout
|
Use subparagraphs for each subsystem or component, with additional subparagraphs for each health hazard discussion. Include sufficient detail to clearly define the specific problem, issue involved and reasoning behind the analyses
| |
Material information
| |
For each proposed and alternative material, include the following:
| |
Material identification. Include material identity; common or trade name; chemical name; chemical abstract service number; national stock number, or local stock number; physical form (solid, liquid, gas); and manufacturers and suppliers.
| |
Material use and quantity
|
Include component name, description, and code, and/or operations details for the material. Total system and program, life-cycle quantities to be used. For mixtures, concentrations for each ingredient.
| |
Hazard identification
|
The detrimental effects of the material on the system, personnel, environment, or facilities.
| |
Toxicity assessment
|
A description of the expected frequency, duration, and amount of exposure. Include the reference documentation and methods used to determine potency/toxicity assessment factors and calculations.
| |
Risk calculations
|
Include classification of severity and probability of occurrence, acceptable levels of risk, any missing information, and discussions of uncertainties in data or calculations.
| |
Material substitutions
|
Discuss the rationale for using a hazardous materiel and long term effects (such as potential for personnel and environmental exposure, handling and disposal issues/ requirements, protection/ control measures, and life cycle costs) over a non or less hazardous material. The effects and costs should be considered over the life of the systems, including the cost of handling and disposal. Identify potential non or less hazardous alternatives if they exist and provide a justification why an alternative cannot be used.
| |
Assessment of health hazard issues
|
Include an analysis of data, observations, findings, reports and other sources of information against health standards and criteria. A discussion of the potential effect of the health hazards identified. An assessment of the risk of the health hazards based on hazard severity and hazard probability. Include when the hazards may be expected under normal or unusual operating or maintenance conditions.
| |
Recommendations
|
Include a description of the system, facility and personnel protective equipment design requirements (e.g., ventilation, noise attenuation, radiation barriers, etc.) to allow safe operation and maintenance. Specify the recommended actions that should be taken to eliminate, reduce or control each actual or potential health hazard described. What is the effect that each action may have on the risk of the health hazard(s).
| |
Summary
|
Include a summary of the major recommendations.
| |
DETAILS TO BE SPECIFIED IN THE SOW
|
Imposition of Tasks 101 and 207.
| |
Minimum hazard severity and probability reporting thresholds.
| |
Any selected hazards, hazardous areas, hazardous materials, or other specific items to be examined or excluded.
