What is a significant risk factor if escalator components are improperly installed?

Improper installation of escalator components can lead to significant safety hazards and accidents, making this the most critical concern. When components are not installed according to the manufacturer's specifications or safety standards, it can create malfunctions or operational issues. This might include misalignment of parts, compromised structural integrity, or failure of vital safety features, all of which may pose serious risks to users.

For example, an escalator might stop suddenly, trap a user's foot, or not respond correctly to emergency stop commands, leading to accidents that could cause injury or, in severe cases, fatalities. Therefore, ensuring that escalator components are installed correctly is paramount for the safety of all users.

While increased energy consumption, user dissatisfaction, and higher maintenance costs are valid concerns, they do not pose immediate threats to user safety like the risk of accidents does. Thus, the greatest focus must always remain on the safety aspect first and foremost.
