• refers to the legislation, policies, procedures and activities that
aim to protect the health, safety and welfare of all people at the
workplace.

11. REASONS FOR OCCUPATIONAL
SAFETY AND STANDARDS ARE:
• Moral – an employee should not have to risk injury at
work, nor should others have associated with the work
environment.
• Economic – many governments realize that poor
occupational safety and health performance results in
cost to state
• Legal – OHS requirements maybe reinforced in civil
law and/or criminal law

12. SAFETY PROCEDURES(OHS)
1. To prevent electrical shock hazard, disconnect the power
cable from the electrical outlet before relocating the system
2. When adding and removing devices to or from the system,
ensure that the power cables for the devices are unplugged
before the signal cables are connected. If possible, disconnect
all power cables from the existing system before you add a
device
3. Make sure that your power supply is set to the correct
voltage in your area
4. Before installing the Motherboard and adding a device on it,

13. 5. To avoid short circuits, keep paper clips, screws,
and staples away from connectors, slots, sockets and
circuitry
6. Avoid dust, humidity, and temperature extremes.
Do not place the product in any area where it may
become wet
7. Always ground or discharge yourself before
touching any part of the computer
8. Do not work alone so that there’s someone who can
take care of you in case of accident or emergency.

14. 10.Always full the cable connector on the handle and not on
the cable itself
11.Use only rubber shoes when standing on the ground or
in a concrete floor
12.Make sure that the pins are properly aligned when
connecting a cable connector.
13.Always power off and unplug the computer before
working on it.
14. Take away any liquid such as mineral water or soft
drinks near your working area or near computers.
15. Contingency measures during workplace accidents, fire

15. SAFETY PRECAUTIONS:
1.Do not work alone so that there is someone to
be incharge in case of emergency.
2.Always power off the computer and unplug
the computer before working on it.
3.Take away any liquid near your working area
to avoid getting electrocuted or accidentally

18. 5S AND 3RS
1. SEIRI (Sort)
Taking out and disposing
unnecessary items.
Some Seiri practice:
Sorting and evaluation
criteria
Disposal tags
Designated storage area
Material list
2. SEITON (Systematized)
Arrangement /organization
of necessary items in good
order for use. Advantage of
arranging tools, supplies and
materials systematically
•Prevent loss and waste of
time
•Easy find and pick up of
necessary items
•Ensure first-come-first
serve basis

19. 3. SEISO (Sweep)
Cleaning of the work place, including tools and equipments.
Seiso also means cleaning even if things are Not Dirty, because a
regular cleaning schedule will prevent things from having chance
to get dirty. It is recommendable to allot time (say a few minutes)
every day to clean the work place. It is much easier and faster if
done on a daily basis. It is good discipline to leave the work
place cleaner than when it found
Big Seiso (Clean Up) Day
•3-5 minutes cleaning daily
•Assign owner to each machine
•Combine cleaning with inspection
•Make daily maintenance clear providing visible instructions
•Provide necessary tools or critical points of cleaning

20. 4. SEIKETSU
(Standardized)
Maintaining the work
place in high standard
of housekeeping and
organization.
Visual management,
Standardization
5. SHITSUKE (Self- discipline)
Maintaining the work place in
high standard of housekeeping
and organization.
Visual management,
Standardization
•Doing things spontaneously
without being told.
•Doing the job alone will not be
