• We all know that increased efforts are being made towards mechanization and
automation to suffice the needs of evolving manufacturing environment.
• Despite of this, use of hand tools and conventional machine tools are still
essential to all young people who aspire to become mechanical or production
engineers.
• These engineers are advised to gain knowledge and experience by individually
operating the machines and using the tools skillfully as there is no real substitute
for practical experience.
• This course of workshop technology is focused mainly on metal cutting
operations.

• It takes few seconds to be safe! Safety means consideration of hazards that can
occur when a machine or its guard fails, or an operator chooses to do a job in a
different way.
• We must therefore understand and practice safe working procedure to avoid
accidents.

A Lab In charge is a responsibility for a safe and healthy working environment for the
workers.
We have to aware with the safety risks within the laboratory or the work places, as
well as the measures you can take to counteract these risks.

• PPE means personal protective equipment or equipment you use to guarantee your
(own) safety.
• Use PPE always and anywhere where necessary. Observe the instructions for use,
maintain them well and check regularly if they still offer sufficient protection. But
when do you use what type of protection?

WORKSHOP-INTRODUCTION
• A room, group of rooms, or building in which work, especially mechanical
work, is carried on.
• Workshop is the core of learning about different Materials, equipment, tools
and manufacturing practices that are observed in different manufacturing
functions and operations.

• It is essential that all employees adopt a positive attitude towards safety.
Protective clothing should be worn wherever necessary.
• Fig 1.1 shows satisfactory and unsatisfactory protective clothing. Eye protection
must also be worn when performing machining operations such as turning,
drilling, grinding. Use face shields in welding area. Safety boots should also be
used. Industrial gloves should be used while handling sharp objects.

Wearing a helmet offers protection and can prevent head injuries.
Select a sturdy helmet that is adapted to the working conditions.
These days you can find many elegant designs and you can choose
extra options such as an adjustable interior harness and comfortable
sweatbands.
The eyes are the most complex and fragile parts of our body. Each day,
more than 600 people worldwide sustain eye injuries during their
work.
Thanks to a good pair of safety glasses, these injuries could be
prevented.
Do you come into contact with bright light or infrared radiation?
Then welding goggles or a shield offer the ideal protection!

Do you work in an environment with high sound levels? In that
case it is very important to consider hearing protection.
Earplugs are very comfortable, but earmuffs are convenient on the
work floor as you can quickly put these on or take them off.

Hands and fingers are often injured, so it is vital to protect them
properly. Depending on the sector you work in, you can choose from
gloves for different applications:
•protection against vibrations
•protection against cuts by sharp materials
•protection against cold or heat
•protection against bacteriological risks
•protection against splashes from diluted chemicals.

• Even your feet need solid protection. Safety shoes (type Sb, S1, S2
or S3) and boots (type S4 or S5) are the ideal solution to protect the
feet against heavy weights.
• An antiskid sole is useful when working in a damp environment,
definitely if you know that 16,2% of all industrial accidents are
caused by tripping or sliding.
• On slippery surfaces, such as snow and ice, shoe claws are
recommended.
• Special socks can provide extra comfort.

• Wearing a mask at work is no luxury, definitely not when coming
into contact with hazardous materials.
• 15% of the employees within the EU inhale vapours, smoke,
powder or dusk while performing their job.
• Dust masks offer protection against fine dust and other
dangerous particles.
• If the materials are truly toxic, use a full-face mask.
• This adheres tightly to the face, to protect the nose and mouth
against harmful pollution.

• Preventing accidents is crucial in a crowded workshop.
• That is why a good visibility at work is a must: a high-
visibility jacket and pants made of a strong fabric can help
prevent accidents.
• Just like the hand protection, there are versions for different
applications.

ELECTRICAL HAZARDS
• Electrical equipment is potentially dangerous. The hazards associated
with it are:-
• Electric shock
• Fire due to overheating of cables, connections and appliances

25.
CAUSES OF ELECTRICAL HAZARDS
• These hazards can result from
• badly designed installations and equipment,
• inadequate maintenance,
• deliberates overloading of installations and equipment.

26.
• Check that the cable is not damaged or frayed.
• Check that the cable is properly secured at both ends and that none of the
conductors is visible.
• Check that the plug is in good condition.
