In a coordinated four level attack on risk, integration of analytical procedures (i.e. Lean Optimization, PM Analysis, and Optimal Reliability) can be achieved by conducting each one against the backdrop of IONICS, a 6-step methodology facilitating matrix management and defined by: Identify risks, Order by importance, Numerate options, Introduce solutions, Control processes and Synthesize new i...

cement dust exposure is associated with increased respiratory impairment. as the major occupational hazard in the cement production industry is cement particles, our aim was to more thoroughly examine the acute effects of occupational exposure to cement dust on the respiratory system. a cross-shift study was conducted in a cement factory in iran. 100 high exposed workers from production and pac...

Cooke (1922) first drew attention to house dust as an etiological factor of asthma. Since then there have been reports of many cases of asthma which were dependent on sensitivity to house dust and occupation dusts, such as wheat dust (miller's asthma) and wood dust {e.g.. teak). In the case of occupational dusts the nature of the allergen is known, but nothing definite is so far known regarding...

in order to compare sampling efficiencies of total and inhalable dust methods, three airborne dust sampling systems , 7-hole sampler , close and open face filter cassette were compared side-by-side , as stationary and for the personal samplers , in a wood working industry to evaluate their relative efficiency. a total of 162 samples were collected. the study of particle size distribution by cas...

Each year, the United States conducts approximately 20,000 inspections of manufacturing plants under the Clean Air Act. This paper compiles a panel dataset on plant-level inspections, fines, and emissions to understand whether these inspections actually reduce air emissions. We find plants reduce air emissions by fifteen percent, on average, following an inspection under the Clean Air Act. Plan...
