Work permit system is a safety procedure to control hazardous work activities and ensure proper authorization and supervision.

• Work permit system is a formal written system used to control certain types of work that are identified as potentially hazardous.

• It ensures that proper authorization is obtained before starting work, and that necessary precautions are taken to minimize risks.

• Examples of work permits include hot work permits for welding, confined space entry permits, an...read more

TBM stands for Tunnel Boring Machine and CBM stands for Condition-Based Maintenance.

• TBM is a machine used to excavate tunnels by drilling through rock or soil.

• CBM is a maintenance strategy where maintenance is performed based on the condition of the equipment rather than a fixed schedule.

• Example of TBM: The Bertha TBM used to dig the SR 99 tunnel in Seattle.

• Example of CBM: Monitoring vibration levels in a rotating machine to determine when maintenance is needed.

Condition monitoring is the process of monitoring the health of machinery and equipment to identify potential issues before they lead to failure.

• It involves using sensors to collect data on various parameters such as temperature, vibration, and noise levels.

• This data is then analyzed using algorithms to detect any anomalies or patterns that may indicate a potential problem.

• By implementing condition monitoring, maintenance can be scheduled proactively, reducing downtime and pr...read more

Maintenance procedures for Electric Overhead Traveling (EOT) cranes

• Regular inspection of the crane structure, electrical components, and mechanical parts

• Lubrication of moving parts to prevent wear and tear

• Checking and adjusting brakes for proper functioning

• Testing emergency stop functionality periodically

• Ensuring proper alignment of wheels and tracks for smooth operation

A confined space is an area that is not designed for continuous occupancy, has limited entry and exit points, and may have poor ventilation.

• Confined spaces can include storage tanks, silos, tunnels, and sewers.

• Precautions include proper training on confined space entry procedures, use of personal protective equipment, and continuous monitoring of air quality.

• Workers should never enter a confined space alone, and a rescue plan should be in place in case of emergencies.

I have extensive experience in maintaining KPIs to track performance and drive improvements.

• Developed KPIs to measure equipment reliability and maintenance efficiency.

• Regularly analyzed KPI data to identify trends and areas for improvement.

• Implemented strategies based on KPI insights to optimize maintenance processes.

• Collaborated with cross-functional teams to align KPIs with overall business goals.

• Implemented a new material handling system in a warehouse, reducing labor costs by 15%

• Collaborated with a cross-functional team to upgrade a production line, increasing output by 25%

Different maintenance strategies include preventive maintenance, predictive maintenance, corrective maintenance, and reliability-centered maintenance.

• Preventive maintenance involves regularly scheduled inspections and maintenance to prevent breakdowns.

• Predictive maintenance uses data and analytics to predict when equipment will fail and perform maintenance before it happens.

• Corrective maintenance is done after a failure occurs to restore equipment to working condition.

• Reliabi...read more

• Training staff on troubleshooting techniques to quickly diagnose and resolve issues

• Utilizing predictive maintenance technologies such as vibration analysis or thermal imaging to predict when equipment may fail

• Regularly monit...read more

Hydraulic systems use fluid to transmit power and are commonly used in various applications.

• Hydraulic systems use incompressible fluid to transmit power

• They consist of a pump, reservoir, valves, cylinders, and motors

• Common applications include heavy machinery, aircraft landing gear, and brakes

• Hydraulic systems can operate at high pressures to generate significant force

• Regular maintenance is crucial to prevent leaks and ensure proper functioning

Electric furnaces are heating devices that use electricity to generate heat for residential or industrial purposes.

• Electric furnaces are commonly used for heating homes, offices, and industrial buildings.

• They work by converting electrical energy into heat through resistance heating elements.

• Electric furnaces are typically more energy efficient than gas furnaces, but may have higher operating costs depending on electricity rates.

• Examples of electric furnaces include electric b...read more
