Under HASAWA, what must employers provide to ensure health and safety as far as is?

The correct answer is focused on the concept of "reasonably practicable," which is a key principle under the Health and Safety at Work Act (HASAWA). This principle highlights the expectation that employers must take practical measures to ensure the health and safety of their employees without incurring disproportionate costs or implementing overly burdensome actions. It emphasizes a balance between the level of risk and the resources available to mitigate that risk.

By defining health and safety measures in terms of what is reasonably practicable, the law recognizes that while employers have a duty to provide a safe working environment, they should also consider the feasibility and economic implications of implementing those safety measures. This allows for a tailored approach that can vary between different workplaces, acknowledging the unique circumstances of each employer.

In contrast, the other options, such as being "legally binding," may imply a stricter obligation that does not account for practicality. "Common knowledge" is too vague and subjective, lacking the specificity needed for legal standards. Finally, "industry standards" can be helpful but do not inherently capture the balance of risk and feasibility emphasized in the principle of "reasonably practicable." This principle is crucial in guiding employers on how to comply with health and safety legislation effectively.
