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 is an applied science that studies the relationship between people and their working environment.
