Mobile ladders must be protected from which of the following?

Mobile ladders are essential tools in various workplaces, and proper care is necessary to ensure their safety and longevity. Protecting mobile ladders from corrosive materials, heat, and weather is crucial for several reasons.

Corrosive materials can cause deterioration of ladder components, particularly those made of metals. Exposure to substances like acids or strong cleaning agents can weaken the structural integrity of the materials, leading to potential failure and unsafe conditions during use.

Heat can also negatively impact mobile ladders, especially if they are made from materials like aluminum or plastic. Extreme temperatures can distort or weaken these materials, compromising their strength and safety. High heat can also cause ladders to become slippery and difficult to grip.

Weather conditions such as rain, snow, and humidity can lead to rust, mold, and other forms of degradation. For instance, moisture can cause wood ladders to swell or rot, while prolonged exposure to sunlight can break down plastics and paints, possibly leading to peeling or brittleness.

Therefore, it is vital to protect mobile ladders from all these factors to maintain their stability, safety, and usability. Such protection ensures that ladders will perform effectively when needed, thus minimizing the risk of accidents and injuries in the workplace.
