Final answer:
In a COSHH assessment, the duration of exposure is a critical factor to consider, with both short-term and long-term exposures posing risks such as respiratory symptoms, healthcare usage, and premature mortality. Safety protocols must be adapted to these durations to manage health risks effectively.
Step-by-step explanation:
When conducting a COSHH assessment, which is critical for managing workplace health risks associated with hazardous substances, one key factor to consider is the duration of exposure. Short-term exposures can lead to respiratory symptoms and increased healthcare usage, including hospital admissions and emergency department visits. Furthermore, these short-term events can have severe consequences such as premature mortality. On the other hand, long-term exposures are associated with the development of chronic heart or lung diseases and can also lead to premature mortality.
It’s important for employers to understand that different jobs can lead to varying levels of exposure. Most occupational exposures happen through the skin, particularly the face, hands, forearms, neck, and chest, and can be compounded by inhalation, especially in enclosed environments. Understanding the duration of exposure helps in tailoring appropriate safety measures and protocols to minimize health risks.
