| Question | Answer |
|---|---|
| Electricity | is a form of energy resulting from the existence of charged particles. It is the flow of electronics |
| Electrical current | when the electrons flow it is called an ____ |
| 1992-2012, 6000, 4.7% | From ____, there were nearly ___ deaths from on-the-job electical accidents. That's ____ of all occupational deaths |
| Fires | electricity is one of the most common causes of fires both in the home and in the workplace. |
| Current | is the amount of electricity flow in a conductor |
| Voltage | is the force which causes electrons to flow in a conductor |
| Resistance | is a opposition of a material to the flow of electricity |
| Direct current | an electric current flowing in one direction only |
| Alternating current | electric current that reverses its direction of flow periodically according to a frequency in hertz, or cycles per second |
| Conductor | any material that offers little resistance to the flow of an electric current |
| Insulator | any material that is a very poor conductor of electricity and prevent current from taking unwanted paths |
| hands and feet | Typical points of entry are the ____ and ___ as they come in contact with electric current |
| Let-go current | the maximum current that a person can tolerate when holding a conductor and can still free himself/herself by muscular stimulation |
| Ventricular fibrillation | most death by electric shock are caused by _____. it is a condition where in the heart will not pulse regularly causing the heart to cease functioning. |
| Rule 1210 | Electrical Safety |
| Rule 1211 | the philippine electrical code is hereby adopted and the standards contained therein shall be considered safety standards to the extent that they safeguard any person employed in any workplace and controls the practice of electrical engineering. |
| Insulation | Electrical _____ is the absence of electrical conduction. |
| Circuit Breakers | these are calibrated conductors which will melt and/or break (open) the electrical circuit when too much current flows through them |
| Ground-Fault Circuit Interrupter (GCFI) | is a fast-acting circuit breaker which senses small imbalances in the circuit caused by current leakage to ground and, in a fraction of a second shuts off the elctricity |
| Grounding | is a conductive connection between electrical circuit or equipment and earth or ground plan. creates a low resistance to the earth. is a protection from electric shock |
| Lockout/Tag-out System | the standard for the control of hazardous energy sources which covers maintenance of machines in which the unexpected startup of machines or release of stored energy could cause injury to employees |
| Lockout device | a device that utilizes a positive means such as a lock to hold an energy isolating device in the safe position and prevents the energizing of a equipment |
| Tagout device | a warning device, such as a tag and a means of attachment |
| Portable equipment | shall be handled in a manner which will not cause damage |
| Constant pressure switch | shuts off power upon release |
| On-off switch | routers, planers, laminate trimmers, shears, and jig saws |
| Double-Insulated Portable Electric Tools | the user is protected in two ways: by normal insulation on the wires inside, and by a housing that cannot conduct electricity to the operator in the event of a malfunction |
| Hand Protection | rubber insulating gloves; classified by the level of voltage and protection they provide. |
| Voltage-Rated Gloves | first line of defense; choose the right size |
| Safety signs and tags | safety signs, safety symbols, or accident prevention tags shall be used where necessary to warn employees about electrical hazards which may endanger them |
| Barricades | shall be used in conjunction with safety signs where it is necessary to prevent or limit employee access to work areas exposing employees to not insulated energized conductors or parts |
| Attendants | if signs and barricades do not provide sufficient warning and protection from electrical hazards, an attendant shall be stationed to warn and protect employees. |
