9. ELECTRICAL
HAZARDOUS
ENERGY
Electrical energy is the most common form
of energy used in workplaces.
It can be available live through power lines
or it can also be stored, for example, in
batteries or capacitors.
Electricity can harm people in one of three
ways:
By electrical shock.
By secondary injury.
By exposure to an electrical arc.

10. CHEMICAL
HAZARDOUS
ENERGY
Chemical Energy is the energy released when a
substance undergoes a chemical reaction.
The energy is normally released as heat, but
could be released in other forms, such as
pressure.
A common result of a hazardous chemical
reaction is fire or explosion.

11. MECHANICAL
HAZARDOUS
ENERGY
Mechanical Energy is the energy
contained in an item under tension.
For instance, a spring that is
compressed or coiled will have
stored energy which will be
released in the form of movement
when the spring expands.
The release of mechanical energy
may result in an individual being
crushed or struck by the object.

12. HYDRAULICS
HAZARDOUS
ENERGY
Hydraulics potential energy is
the energy stored within a
pressurized liquid.
When under pressure, the fluid
can be used to move heavy
objects, machinery, or
equipment.

13. PNEUMATIC
HAZARDOUS
ENERGY
Pneumatic potential energy is
the energy stored within
pressurized air. Like hydraulic
energy, when under pressure,
air can be used to move heavy
objects and power equipment

14. THERMAL
HAZARDOUS
ENERGY
Thermal hazards are hazards that
can alter your body temperature in
a harmful way.

23. What are the steps
involved in developing
a Hazardous Energy
Control Program?

24. 1.Gather information.
2.Perform a task analysis.
3.Perform a hazard and
risk analysis.
4.Implement controls
5.Communication,
including training.

25. Gathering Information
Begin by gathering documentation from the manufacturer
or designer of the system about:
●Where energy isolating devices are located and
procedures for their use.
●Step-by-step procedures for servicing or maintaining the
system.
●How safety address malfunctions, jams, misfeeds, or other
planned and unplanned interruptions in operations
●How to install, move, and remove any or all parts of the
system safely.

26. Performs a Task Analysis
●A task identification analysis is performed by examining
all the intended uses of the system from the perspective
of both the manufacturer and the user. List all tasks and
steps required to accomplish the task. This analysis should
also include any tasks related to any possible misuse of
the system.

27. Perform a Hazard and Risk Analysis
●Based upon the information from the first two steps,
perform a hazard and risk analysis of how workers will be
interacting with the system. This analysis should outline
where possible hazards are, and what the associated risk
of each hazard exists.

28. Implement Controls
●the controls required will follow what hazards and risks
were identified during the analysis and assessment. For
example, Identifu what types of hazardous energy are
present in a system that needs to ne controlled, and what
types of energy-isolating and de-energizing devices are
required.

29. 5. Communication, including Training
●Communicate and train appropriate starf on how the
program works, their role in the program, and what their
responsibilities are.

30. WHAT IS
LOCKOUT/
TAGOUT?
Lockout-tag out (LOTO) or lock and tag
is a safety procedure which is used in
industry and research settings to ensure
that dangerous machines are properly
shut off and not able to be started up
again prior to the completion of
maintenance or servicing work.

31. ●Prepare for shutdown
●Shut off the machine and/or energy supplies.
●Disconnect or isolate the machine from the energy
sources.
●Apply the lockout or tagout devices to the energy-isolating
devices.
●Release l, restrain or render safe potential hazardous
stored/ residual energy.
●Ensure accumulated energy does not reaccumulate to
hazardous levels.
●Verify the isolation and degeneration of the machine.

32. Yes, annual OSHA training for all
employees is mandatory, and training
for new-hire employees must be
completed within ten days of hire.
HIPAA requires organizations to
provide training for all employees, new
workforce members, and periodic
refresher training. The definition of
“periodic” is not defined and can be
left open to interpretation. However,
most organizations train all employees
on HIPAA annually. This is considered
to be a best practice. Regulations are
updated yearly, so it can be difficult for
practices to stay current. Failure to
comply can result in fines or other
consequences.

33. OSHA & HIPAA requirements as of 2013 includes:
Annual OSHA Employee Training
GHS: Global Harmonization System Proof of Training
HIPAA Omnibus Rule Employee Training & Implement
Protocols
The following topics must be given to new employees,
or if there is a change in the job procedures that
introduces a new hazard:
General Office Safety – including injury and illness
prevention program (IIPP), fire safety and emergency
responses, eyewash stations, and washrooms.
Hazard Communication
Ionizing Radiation
Bloodborne Pathogens – including medical waste
management information.

36.  Electrical hazards are listed as the cause of approximately
4,000 injuries annually.
 Electrical incidents are far more likely to be fatal.
 Electricity ranks sixth among all causes of occupational injury
in the United States.
 Electricity is the cause of more than 140,000 fires each year,
resulting in 400 deaths, 4,000 injuries and $1.6 billion in
property damage.
 Total economic losses due to electrical hazards are estimated
to exceed $4 billion annually.
 About 5 workers are electrocuted every week.
 Electricity causes 12% of young worker workplace deaths
 Electricity takes very little electricity to cause harm.
 It has significant risk of causing fire.

electrical current passing through the body.

41. ELECTROCUTION
• Electrocution is death or serious
injury caused by electric shock,
electric current passing through
the body.
• The word is derived from
"electro" and "execution", but it is
also used for accidental death.
BURNS
ELECTRIC SHOCK
FALL
An electric shock is received when electrical
current passes through the body.
You will get an electric shock if a part of your
body completes an electrical circuit by:
• Touching a live wire and an electric ground,
or
• Touching a live wire and another wire at a
different voltage.
Most common shock-related injury
Occurs when you touch electrical wiring or
equipment that is improperly used or
maintained
Typically occurs on hands
Very serious injury that needs immediate
attention
Electric shock can also cause indirect
injuries
Workers in elevated locations who
experience a shock may fall, resulting
in serious injury or death

42. GENERAL SAFETY TIPS FOR WORKING WITH
OR NEAR ELECTRICITY
Inspect portable cord-and-plug connected equipment, extension cords, power bars, and
electrical fittings for damage or wear before each use. Repair or replace damaged
equipment immediately.
Always tape extension cords to walls or floors when necessary. Nails and staples can damage
extension cords causing fire and shock hazards.
Use extension cords or equipment that is rated for the level of amperage or wattage that you
are using.
Always use the correct size fuse. Replacing a fuse with one of a larger size can cause
excessive currents in the wiring and possibly start a fire.
Be aware that unusually warm or hot outlets may be a sign that unsafe wiring conditions
exists. Unplug any cords or extension cords to these outlets and do not use until a qualified
electrician has checked the wiring.
Always use ladders made with non-conductive side rails (e.g., fibreglass) when working with
or near electricity or power lines.
Place halogen lights away from combustible materials such as cloths or curtains. Halogen
lamps can become very hot and may be a fire hazard.

43. Risk of electric shock is greater in areas that are wet or damp. Install Ground Fault Circuit
Interrupters (GFCIs) as they will interrupt the electrical circuit before a current sufficient to
cause death or serious injury occurs.
Use a portable in-line Ground Fault Circuit Interrupter (GFCI) if you are not certain that the
receptacle you are plugging your extension cord into is GFCI protected.
Make sure that exposed receptacle boxes are made of non-conductive materials.
Know where the panel and circuit breakers are located in case of an emergency.
Label all circuit breakers and fuse boxes clearly. Each switch should be positively identified
as to which outlet or appliance it is for.
Do not use outlets or cords that have exposed wiring.
Do not use portable cord-and-plug connected power tools with the guards removed.
Do not block access to panels and circuit breakers or fuse boxes.
Do not touch a person or electrical apparatus in the event of an electrical accident.
Always disconnect the power source first.
GENERAL SAFETY TIPS FOR WORKING WITH
OR NEAR ELECTRICITY

44. TIPS FOR WORKING WITH POWER
TOOLS
• Switch all tools OFF before connecting them to a power supply.
• Disconnect and lockout the power supply before completing any
maintenance work tasks or making adjustments.
• Ensure tools are properly grounded or double-insulated. The grounded
equipment must have an approved 3-wire cord with a 3-prong plug. This
plug should be plugged in a properly grounded 3-pole outlet.
• Test all tools for effective grounding with a continuity tester or a Ground
Fault Circuit Interrupter (GFCI) before use.
• Do not bypass the on/off switch and operate the tools by connecting and
disconnecting the power cord.
• Do not use electrical equipment in wet conditions or damp locations
unless the equipment is connected to a GFCI.
• Do not clean tools with flammable or toxic solvents.
• Do not operate tools in an area containing explosive vapours or gases,
unless they are intrinsically safe and only if you follow the manufacturer's
guidelines.
