Energy Isolation

Guide for LO/TO (Lock Out / Tag Out) Don't be a VICTIM... Don't be a KILLER... Purpose of Lock Out / Tag Out: To protect workers from the release of hazardous energy To guard against the accidental start-up of equipment during service and maintenance Distinction must be made between LO/TO and various other locking practices, collectively referred to as Administrative Locking LO/TO:Is a specific procedure to ensure Zero-Energy in the system and allow personnel to service, maintain, or modify...

Early Detection System

Thermographic Inspection and Ultrasound Inspection What is Thermography? Camera capture and converts the infrared radiation into a state that is visible to us. That is how we can see and measure the heat. Emissivity or Emittance: The intensity of the emitted radiation depends on two factors, the temperature of the object and the ability of the object to radiate What makes Thermography so unique and useful? Thermography provides us with a powerful tool for non-contact temperature measurement,...

Guide for Electrical Testing and Inspection

Electrical Maintenance Program and Principle of Electrical Testing Electrical Maintenance Activities Fall into three General Categories: I. ROUTINE MAINTENANCE Activities that are conducted while equipment and system are in service. These activities are predictable and can be scheduled, staffed and budgeted. Generally this are schedule on a time –based, run time meter or number of operation schedule. Examples: Visual Inspection  Infrared Scans Cleaning Functionality Test Lubrication Oil...

Electrical Safe Working Environment

An electrically safe work condition will be achieved and verified by the following process: Determine all possible sources of electrical supply to the specific equipment. Check application up date drawings, diagram and identification tags. After properly interrupting the load current, open the disconnecting devices for each source. Where it is possible, visually verify that all blades of the disconnecting devices are fully open or that draw-out type circuit breakers are withdrawn to the fully...

Electrical Emergency Response

When an electrical accident occurs, due to effect of muscle clamping, a victim is often incapable of moving or releasing the electrical conductor. Attempts to rescue an accident victim may pose as a great hazard for the rescuer as it does for the victim. Caution should be a primary consideration during any electrical accident or emergency. There should be an emergency response plan for scheduled electrical maintenance or work. A worker with an electrical...

Electrical Hazards

Current is the killing factor of Electricity Three Categories of Electrical Hazard ELECTRICAL SHOCK To some people low voltage means low hazard. Actually, low voltage does not necessary means low hazard, because potential difference is only a factor making up dangerous effect of electricity. The terms high voltage and low voltage are relative terms. The term low voltage is really deceiving. The extent of injury from electrical shock depends on these factors: • The amount of current...

Two Basic Types of Electricity

I. STATIC ELECTRICITY Static Electricity is an accumulation of electrical charges on the surface of a material, usually an insulator or non-conductor of electricity. There is no current flowing as there is in alternating current (AC) or direct current (DC) electricity. Static Electricity is simply electricity that is standing still - voltage potential with no electron flow. Typically, two materials are involved in static electricity: 1. It has excess electrons or negative (−) charges on...

Fundamentals of Electricity

Analogy of Voltage, Current and Resistance. Voltage Voltage is the electrical force that moves electrons through a conductor. Voltage is electrical pressure also known as EMF (Electro Motive Force) that pushes electrons. The greater the difference in electrical potential push (difference between positive and negative), the greater the voltage force potential. Current Electric current is a flow of electric charge through a medium. This charge is typically carried by moving electrons...
