Which facility would be an example of a substantial hazard in risk category III?

A nursing home is an example of a substantial hazard in risk category III because it houses individuals who are highly vulnerable, particularly to risks that can lead to life-threatening situations. Facilities in this category typically include those that provide care or special services to populations that may require assistance, such as the elderly, patients with disabilities, or those who are medically vulnerable.

In the case of a nursing home, the potential for a substantial hazard stems from the presence of residents who may have limited mobility, depend on specialized medical care, or require immediate assistance in the event of an emergency. Therefore, the safety features and structural integrity of the building are critical to ensuring the well-being of its occupants.

Other facilities like storage unit facilities, office buildings, and farm barns do not typically involve the same level of risk to individuals' health and safety due to their use and occupant profiles, which generally do not depend on immediate assistance or have a higher likelihood of being affected by structural failures or emergency situations.
