An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl â (aq).
Individual ergonomic assessment. An ergonomic evaluation is a formal, structured process that assesses many physical and cognitive parameters of the worker, the workspace, and the job characteristics to determine if the job fits the worker and to identify ALL risk factors for repetitive strain injury (RSI) .
In particular, ergonomics focuses on the physical interface between the worker and the way he or she uses the tools of their job. A tool such as a computer workstation is said to have good ergonomic design when it can be easily adjusted to fit the user.n particular, ergonomics focuses on the physical interface between the worker and the way he or she uses the tools of their job.
