All workplace hazards either chemical or physical can be controlled through elimination and substitution. Elimination is the removal of the hazard from the workplace whereas substitution involves the introduction of a new and less hazardous chemical or substance instead of another chemical (Channel 1 & Kanopy (Firm), 2013). Both elimination and substitution serve the purpose of removing the hazard from the workplace. This is the most reliable and effective hazard control method. For example, safety should be considered when purchasing a machine to be used in workplaces. Machines that do not conform to national safety standards by failing to design safety guards to protect its users from injuries, such machines should not be purchased. By doing so, the hazard of injuries at the workplace is removed. Another example is a scenario of a place I previously worked whereby ergonomic floor mats were introduced at workstations to replace the slippery tiled floor which had led to the injury of four employees. The introduction of ergonomic floor mats helped to eliminate the slip and trip hazard at workstations.
Hazard elimination control method is the most effective and reliable method compare to other hazard control methods because the hazard is removed and depends little on human intervention. It is advantageous in cost saving by eliminating the hazard in the early stages of the process since the organization may never encounter the hazard in future. The main disadvantage is that elimination method can be sometimes impossible to apply in certain activities or processes because the substance in use is mandatory and does not have an alternative option. It is also costly to eliminate or replace the hazard. Moreover, a possible sacrifice of production and loss of jobs is encountered in elimination method. For instance, when a certain process or activity that is speculated as a possible hazard is removed in an organization, some people will lose their job due to retrenchment (Vocam Worldwide Publishing, 2009).
