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) .
Ergonomics focuses on identifying strategies to allow you to perform the job in the most efficient manner possible, with the least amount of strain on your body. The more frequently or forcefully you do a task, the more important it becomes for you to pay attention to the ergonomics of the task.
