Workshop safety
Introduction
Safety definition; it is the condition of being free from danger, risk or threat of harm,
injury or loss of life and property whether caused by intentional human actions or by
accidents.
Workshop safety is an important in any sewing industry either in hand sewing, using a
sewing machine both electrical or manual sewing machine. Individuals encounter
several risk factors as they go about their daily activities hence safety measures have
to be taken seriously. Safety is important to everyone and it is one’s responsibility to
maintain a safe working place. The following rules have been put in place to ensure
the safety of everyone;
Workshop safety rules
1. When operating the machine, do not be careless.
2. Always inspect the machine before starting the work. Be sure it is clean and threaded
correctly, with no loose threads on the pulley belt and all guards in place.
3. When in doubt, ask the teacher.
4. Report any injuries or accidents immediately to the teacher.
5. Wipe up any oil spilled on the floor immediately to prevent anyone from slipping.
6. Operate machines only with permission.

12. Keep your feet off the treadle when you are setting or threading the needle.
13. Turn the motor off when you are not stitching.
14. Turn the motor off before cleaning, oiling or adjusting the machine.
15. Turn the motor off before removing or replacing the pulley belt and run the machine
out. Wait until all motion has stopped.
16. Turn the motor off in case of an emergency or when in doubt.
17. Turn the motor off before unplugging the machine.
18. Do not use your hand to stop and start the hand wheel.
19. Use your hand only to set the hand wheel.
20. Before operating the machine, close the slide bed cover.
21. When operating the machine, keep your hands, scissors and other sharp objects away
from the belt.
22. Keep the machine and work station clean with all tools in the side drawer.
23. Unplug the machine at the end of the day.
24. Know the location of the main power switch, outlets and fuses in case of an
emergency.
25. Do not remove any safety devices from the machines.
26. Turn off the iron at the end of the class.
27. Always place the iron on the iron pad to avoid burning the ironing board cover.

29. Scissors should be handed to another person with the handles toward the person.
30. Never toss or throw scissors or equipment.
31. Do not eat or drink in the work area.
Reasons for workshop rules
• To protect property
• To prevent loss of lives
• To enable smooth flowing of work
• To prevent accidents
, Personal Protective Equipment
This are protective equipment or garment designed to protect the wearer’s body from
injury or infection. These injuries or infections may result from contact with
chemicals, physical, electrical, mechanical or other work place hazards. This
equipment may include items such as;
Gloves
Low heeled closed shoes
safety glasses
overalls/dustcoat
thimble
face mask
Benefits of Personal Protective Equipment in Garment Industry.
1. Lowers the risk of Respiratory Problems
Inhalation of gases, smoke, and chemicals can impact your respiratory negatively.
These contaminants are toxic; therefore, they can lead to short term and long term
respiratory-related illnesses. A worker should be fully equipped with hearing
protection, eye protection, and flame-resistant gears. These protective garments will
prevent health issues, such as irritation and breathing difficulties. You should use
respirators in incidences where there’s insufficient ventilation.
2. Prevent Injuries from Corrosives
If you’re dealing with chemicals, it’s a great and safe idea to wear full personal
protective clothing. Concentrated chemicals are corrosive and harmful. Therefore,
dangerous chemicals can impact your skin or eyes when there’s a spillage or leaking.
Double-check your protective gear to ensure that you’re fully protected. Chemical
spillage can lead to long term health impacts, thus reducing your production.
Therefore, it’s crucial to invest in the right protective clothing.
3. Protects your Body from Extreme Cold and Heat
