 Insulation - From the Latin word for island
(insula). Insulation is the noun describing
material which insulates (cuts off) heat (or
electricity) from its surroundings. It is a
scientific noun and was first recorded in 1870.
 Insulation is defined as a material or
combination of materials which retard the flow
of heat. The materials can be adapted to any
size, shape or surface. A variety of finishes are
used to protect the insulation from mechanical
and environmental damage, and to enhance
appearance.

 Reduce heat loss or heat gain to achieve energy
conservation.
 Control surface temperatures for personnel and
equipment protection.
 Control the temperature of commercial and
industrial processes.
 Prevent or reduce condensation on surfaces.
 Increase operating efficiency of
heating/ventilation/cooling, plumbing, steam,
process and power systems.
 Prevent or reduce damage to equipment from
exposure to fire or corrosive atmospheres.
 Reduce noise from mechanical systems.

 Removable insulation is specifically designed
to insulate piping systems transporting gas
and substances at high temperatures. The
materials used to construct the insulation
work to prevent your pipes from overheating,
while keeping the warmth inside the pipe. This
helps to cut down on energy bills for your
facility, saving you money in the long run.
 Used material LRB( Light Resin Bond)
 Required temperature up to 80 °C

 Just like hot insulation materials, some of the materials used to produce cold
insulation vary dependent upon the system of pipes they are insulating.
Therefore, the materials used in either hot or cold insulation are dependent
on the customization of the particular piping system. Two common materials
used in cold insulation are:
 Polyurethane Foam: Perfect for handling low thermal conductivity and
substances with below freezing temperatures. Polyurethane foam also allows
for low smoke emission and low water vapor permeability. : Rubber foam is
also often recommended for condensation control as the closed cell
technology is highly resistant to moisture vapor. With chilled insulation,
keeping the cold in is as important as keeping the heat out. There are many
types of insulation used on chilled water pipes. The two most popular are
foam glass and rubber insulation or Arm flex. Although a little more difficult
to work with than pre molded fiberglass, when installed correctly, these
materials do a great job of stopping condensation and preventing energy
loss.

 Acoustic insulation is meant to reduce the level
of good in a given expanse by preventing good
waves from peppy soured the walls and ceiling,
while preventing the onset of good through the
walls. Required for 85 decibel or more sounded
area
 It’s mainly used high noise pipe line, motor,
control valve etc.

 At or below 0 °C (32 °F), blood vessels close to the
skin start to constrict, and blood is shunted away
from the extremities via the action of glomus
bodies. The same response may also be a result of
exposure to high winds. This constriction helps to
preserve core body temperature. In extreme cold,
or when the body is exposed to cold for long
periods, this protective strategy can reduce blood
flow in some areas of the body to dangerously low
levels. This lack of blood leads to the eventual
freezing and death of skin tissue in the affected
areas. There are four degrees of frostbite. Each of
these degrees has varying degrees of pain.

Falls are the number one cause of fatalities in
the construction industry accounting for
approximately 56% of all fatalities
All employees shall be protected from falls of
1.8m or more by the use of an approved fall
protection system
Railings are required at permanent elevated
locations greater than or equal to 1.3m

 Use full body harness
 Safety net are to used
when work place
more than 25feet
above the surface
 Use certified scaffold
 Use rope for material
lifting and lowering
 Only trained and
physically sounded
person should be do
the work.

Derived from two Greek words:
“Nomoi” meaning natural laws
“Ergon” meaning work
Hence, ergonomists study human
capabilities in relationship to work
demands
Loading capacity –
Always use trolley for material
shifting

 Always Use proper hand tools
 Always use required PPE’S
 Always use certified &
Inspected electrical equipment

Soil pollution
Insulation waste mostly related to soil
because insulation waste didn’t soluble in
soil and it didn’t burn it also.
