What type of checks are performed regarding warning devices before starting a forklift?

Functionality checks are crucial before starting a forklift because they ensure that all warning devices are operational and effective in alerting operators and others in the vicinity. These checks typically involve testing alarms, lights, and other signals to confirm that they perform as intended. A functional warning device is essential for maintaining safety on the job site, as it provides necessary alerts to prevent accidents and injuries.

While visual inspections are important for confirming the condition of equipment, they do not guarantee that the warning devices will function correctly when needed. Noise levels might be checked in another context, but they are not a standard procedure for assessing warning devices. Battery strength tests are vital for ensuring that the forklift has enough power to operate, yet they do not directly assess the status of warning systems. Therefore, the emphasis on functionality checks is key to ensuring that safety mechanisms are reliable before operating the forklift.
