for the flow of energy to occur you need the combination of

(electron flow, voltage source and consuming device), (electricity, wiring and equipment) and a generating source with a conductor and load

a hard hat that should be worn in working areas where there is possible danger of head injury from

impact, electrical shock or burns and falling or flying objects

shock can result when your body is

in contact with two wires of an energized circuit and ground

proper lockout tagout of electrically powered equipment includes

indicating circuits or pieces of equipment are out of service on tag

to prevent electrical accidents

insulate

the materials that are considered potential fuels include

lumber , gasoline and chemicals

the types of hand hazards that you can be exposed to on a jobsite include

mechanical, chemical and enviormental

a (blank) energy source requires a lockout tagout

mechanical, hydraulic and electrical

if required to wear a respirator, you must first have

medical evaluation

a physical hazard that can threaten saftey

noise, heat and utilities underground

a conductor of electricity includes

perspiration

lockout tagout devices should be on

power sources

before entering a confined space know the

precaughtions needed, saftey/ ppe needed and nature of hazard

the first step to lockout tag out is

prepare for the shutdown

toxic air contaniments can come from

previously stored material, use of coatings/cleaners and work being performed.

PASS method is

pull, aim, squeeze, sleep

a person who is by education or professional standing, or who by extensive knowledge ,training and extensive work experience has successfully demonstrated their ability to solve or resolve problems is called a

qualified person

after servicing of electrical or mechanical equipment you should first

remove the lock if you applied it

if an emergency occurs, you should know

reporting procedures, escaping procedures and rescue and medical duties

the type of hand protection that should be used to prevent exposure to caustic chemicals is (blank) gloves

rubber,vinyl and neoprene

the type of foot protection that should be used to prevent accumulation of static electricity

static dissipative boots

the two types of grounding are

the electrical circuit and electrical equipment

if sufficient ventilation can't be obtained

use a air line respirator

to put out an electrical fire

use class c fire extinguisher

example of confined space

ventilation ducts

a tag acts as a

warning

the operation time for most fire extinguishers is

8-10 seconds

the types of materials that can cause eye injuries

dust , metal and vapors

oxygen becomes dangerous at

23.50

responding to a chemical spill or hazardous waste cleanup requires training in

HAZWOPER

if an incident results in any fatalities or three or more persons hospitalized, your employer must notify

OSHA

understanding how electricity works requires knowlege of

VOLTS = CURRENT x RESISTANCE

hazards that can cause electrical injury include

a cracked extension cord

if the employer who applied the lock out tagout is absent, they can be removed by

a qualified person

an accidental release of hazardous energy could cause

accidental startups, electric shock and the release of stored energy

there are many different makes and styles of respirators, but all of them fall into two types which are

air purifying respirators and atmosphere ing supplying respirators

for an evacuation , you should know the

alarm system sounds, emergency exits and headcount location

locking out equipment is completed when

all power sources that can be locked are locked out

a confined space is dangerous when there are

atmospheric hazards ,physcial, and underground utilities

if your a trained attendant you should

be knowlegable in first aid, be in constant communication with entrant and remain outside the space

hard hat that provides no voltage protection

class c

if your company acts as an outside contractor , you must be informed of

company objectives and lockout tagout procedures

the hazards faces on a jobsite that could cause foot injuries include

compression

The Assured Grounding Conductor Program requires the following test to be conducted before first use of new equipment

continuity test, grounding conductor test and visual inspection

flammable gases and vapors can ignite by

friction, hot surfaces, and cutting

four basic compoents are needed for a fire to start and they are

fuel, ignition source , oxygen and a chain reaction

equipment needed for entering a confined space

full body harness

the type of eye protection that should be used to guard against dust particles is

goggles

the two major job site fire hazards are flammable and combustible liquids along with

heating devices

arcing occurs when

high amperage current jumps through air, circuits are opening and closing and static electricity is discharged
