What action is required when the cylinder must be replaced due to excess liquid usage?

When a cylinder must be replaced due to excess liquid usage, it's essential to inform the building owner of the necessary actions. This step is crucial because the building owner is ultimately responsible for maintaining the elevator system and ensuring it operates safely and efficiently. By informing the owner, they can take appropriate measures to address the issue, which may involve coordinating with qualified technicians to replace the cylinder and ensuring compliance with safety standards and regulations.

While contacting an elevator technician is indeed important for resolving the technical issue, the owner's involvement is key for initiating repairs and ensuring that the safety of the elevator system is not compromised. Additionally, notifying a local health department or continuing to use the faulty cylinder are not appropriate actions, as these could lead to safety hazards or non-compliance with regulations.
