Risk Analysis of Carbon Nanotube Production Processes under Uncertain Occupational Health Risks and Regulatory Standards
نویسندگان
چکیده
Despite the many touted benefits of nanotechnology, considerable uncertainty exists regarding full-scale production costs, occupational health risks, and future regulatory standards. Monte Carlo models were developed to investigate the implications of these uncertainties on high pressure carbon monoxide (HiPco) processes, a common single wall carbon nanotube (SWNT) production method. The health risks and production costs under alternate investments in occupational safety protection are shown to be significantly unpredictable, due to the large amount of uncertainty in model inputs. Experimental design methods therefore were used to identify which uncertainties have the greatest impact on this unpredictability to help manufacturers, policy makers, and researchers make informed decisions and research investments.

Risk Analysis Modeling of Production Costs and Occupational Health Exposure of Single-Wall Carbon Nanotube Manufacturing
Considerable uncertainty exists about occupational risks, future environmental health and safety (EHS) standards, and associated production and compliance costs for single-wall carbon nanotube (SWNT) manufacturing processes. We propose and illustrate the use of risk analysis Monte Carlo (MC) models to assess cost and exposure trade-offs of the highpressure carbon monoxide (HiPco) SWNT manufactu...

Background: Research project risks are uncertain contingent events or situations that, if transpire, will have positive or negative effects on objectives of a project. The Management of Health and Safety at Work (MHSW) Regulations 1999 require all employers and the self-employed persons to assess the risks from their work on anyone who may be affected by their activities. Risk assessment is the...
