Final answer:
Key factors in assessing health risks in a COSHH Assessment include the identification of substances and their hazards, pathways and duration of exposure, potential for accidents, control measures in place, workforce susceptibility, regular review of the assessment, and training of employees.
Step-by-step explanation:
In the context of a COSHH (Control of Substances Hazardous to Health) Assessment, several key factors need to be considered when assessing health risks. Initially, one must identify the substances in use and their inherent hazards. This includes the chemical's toxicity, form, and concentration, as well as potential interactions with other chemicals. Subsequent considerations involve the pathway of exposure to the substance, such as inhalation, skin contact, or ingestion, and the duration and frequency of exposure. Moreover, the potential for accidents or unexpected releases of the chemicals forms a critical assessment area. Furthermore, one should review the adequacy of existing control measures, such as ventilation systems and PPE, and determine if they are sufficient to mitigate risks.
The workforce's susceptibility, including consideration of vulnerable groups (i.e., pregnant workers), and the environment in which the substance is used also play pivotal roles in the assessment. Regularly reviewing and updating the risk assessment to reflect changes in work practices, legislation, and scientific knowledge is essential for ensuring ongoing safety. Additionally, training employees on the hazards and proper handling procedures aligns with OSHA's requirement to inform workers about chemical hazards.
