Maintenance managers always want their employees to work efficiently, follow procedures, and comply with OH&E Standards. However, when the work environment is in poor conditions, workers do not feel compelled to follow the appropriate guidelines. In fact, an untidy, dirty, and unorganized working environment encourages employees to acquire bad working habits. Consequently, if we want to improve our personnel’s work ethic, we first need to evaluate whether the environment inspires people to work efficiently and correctly or if it does the exact opposite. If latter situation is presented, we need to make improvements before asking workers to change their habits. The best way to guide this improvement process is to implement 5S in the work environment.
5S is a methodology to clean, to improve, and keep the workplace in optimal conditions Continue reading
In the fist part, I talked about problems in general and chronic problems. Now I’m going to discuss about the other type, the emergencies or acute problems.
Acute cases are more critical. We are unable to fix the equipment until we identify the cause of the problem. This is an extremely tense situation, especially in fast paced environments. Usually after the most common repairing options have failed, technicians tend to start replacing every component in the system, sometimes all of them at once. This is highly ineffective and only complicates more the situation. Consequently, the most important thing in these cases is to adopt a methodical approach even if it seems to be slower. This approach is called Fault isolation Process. Continue reading
When equipment fails we need to repair them as soon as possible, especially in a fast paced environment where availability is a critical issue. The key to effectively solving technical problems is to quickly find the cause and take actions to fix it. However, this process is usually not as easy as it sounds.
Sometimes maintenance actions put the machine back on service even if the cause still there. In doing this, we are likely to have the same problem again in the near future. Other times the cause of the failure is not so evident, and the asset remains out of service because we are unable to find what is wrong.
Each of the cases above has its particularities and requires different maintenance approaches depending on the situation. Continue reading
Effective maintenance tasks for each equipment are crucial for maintenance management. Many resources are used to design the tasks in order to improve a plant’s reliability and productivity. However, the way we incorporate all tasks in work orders (WOs) and schedule them will determine the final efficiency of our preventive maintenance strategy.
To effectively schedule the WOs, we use different criteria to group them. Each group has pros and cons, and in practice we usually apply a combination of them to get the most of our resources and increase our department efficiency.
