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

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

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

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
