Workshops, hand process

OSHA uses this term to indicate that the PrHA leader must have competence in the selected PrHA method as applied to process systems. However, OSHA has not formally defined "knowledgeable". A minimum interpretation could include completion of a "hands-on" type workshop on the PrHA method chosen experience in an actual PrHA, led by another experienced PrHA leader, using the chosen method and ability to effectively lead a technical brain-storming type meeting. 

A similar method has been used several times in risk analyses of existing Norwegian road tunnels. The initial part o f the risk assessment process has been carried out in a workshop where experts on the system at hand participated, and the information gathered in the workshop was subsequently refined by the risk analysts. 

Finishing and repairing is done with mixtures of cement and epoxy resins. The workers in the batch plant have contact with wet cement primarily on the hands, but the entire body can be exposed to cement when spills occur (Fig. 2). Most of the work processes are carried out in large workshops, and those workers who have daily contact with wet cement often use leather or rubber gloves. 

An internal combnstion engine is just one example of a complex system. There will be many opportunities to nse our fundamental knowledge of chemistry to better understand complex, real-world systems. Other examples include a wide variety of processes involved in industrial chemical production, the molecular processes that determine cellnlar behavior, and the chemical processes affecting the formation of pollntants in nrban environments. At the workshop, Jim Heath made a presentation on nanochemistry, i.e., nanoscale molecular processes. One of the most intriguing aspects of nanoscale phenomena is that nanoscale systems are the first systems to exhibit mnltiple scales in chemistry—the molecular scale and the nanoscale. Phenomena at the molecular scale are characterized by time scales of femto- to picoseconds and distance scales of tenths of a nanometer to a nanometer. Nanoscale phenomena on the other hand often operate on micro- to millisecond (or longer) time scales and over distances of 10-100 (or more) nm. So, in addition to whatever practical applications nanochemistry has, it also represents a opportunity to understand how to describe disjoint temporal and spatial... 

This course consists of a set of learning modules or workshops, each of which is intended to enhance your understanding of process control and simulation theory and application through hands-on experience using the latest simulation technology and actual laboratory experiments.
