By implementing effective maintenance and repair strategies, laboratory professionals can minimize downtime, reduce costs, and maintain the integrity of their research.
This article explains the importance of preventive maintenance for lab equipment and outlines key areas to focus on when performing maintenance tasks.
Let’s begin.
Understanding Preventive Maintenance
Preventive maintenance is a proactive approach to maintaining lab equipment, keeping it in optimal condition, and avoiding unexpected breakdowns and costly repairs. This approach involves scheduling regular inspections and performing routine maintenance tasks such as lubrication, calibration, and cleaning.
Preventive maintenance is essential for the smooth operation of laboratories. It is critical for cutting maintenance costs, reducing unplanned downtime, increasing equipment lifespan, and ensuring staff safety. The goal is to prevent equipment failure before it occurs and guard against workplace accidents and contamination.
Taking precautions to forestall accidents and contamination improves your business reputation and ensures compliance with industrial, regulatory, and safety requirements. It also contributes to environmental protection, as well-maintained lab equipment is less likely to end up in landfills.
Examples of preventive maintenance tasks include:
-
Scheduling and performing regular inspections
-
Cleaning and decontaminating lab equipment immediately after use or according to manufacturer’s instructions
-
Lubricating moving parts to reduce wear and tear
-
Regular calibrations and adjusting controls for optimal performance and energy efficiency
-
Repairing and replacing defective parts.
