In which type of location should appliances not be installed without protection?

Appliances should not be installed in a vehicle impact damage area without proper protection due to the significant risk of physical impact that could result in serious damage to the appliances. In environments such as parking lots or places where vehicles are in close proximity, appliances are vulnerable to being struck, which could compromise their functionality, safety, and even lead to potential hazards like leaks or electrical problems.

Protection measures, such as barriers or enclosures, are essential in these areas to mitigate the risk of damage from accidental collisions. This emphasizes the importance of considering the specific environmental factors that could jeopardize the integrity and safe operation of appliances.

In contrast, while other areas such as high humidity, low temperature, and electrically hazardous locations present challenges, they do not inherently involve the same level of direct physical threat that necessitates protection against impact like the vehicle impact damage area does.
