Details of Constructions

1. Safety Equipment
Safety is the state of being "safe" (from French sauf),
the condition of being protected against physical, social,
spiritual, financial, political, emotional, occupational,
psychological, educational or other types or consequences of
failure, damage, error, accidents, harm or any other event
which could be considered non-desirable. This can take
the form of being protected from the event or from exposure
to something that causes health or economical losses. It can
include protection of people or of possessions.
Safety Equipment is important for worker protection, as
well as for comfort in your work environment. Safety
gear is designed to suit your work environment; for example,
safety clothing can be insulated or cooling, high visibility,
flame retardant, or chemical resistant.

6. Md. Akhtar Hossain
Lecturer (CE) KUET
How Hard Hats Protect You
Hard hats protect you by providing the following features:
 A rigid shell that resists and deflects blows to the
head.
 A suspension system inside the hat that acts as a
shock absorber.
 Some hats serve as an insulator against electrical
shocks.
 Shields your scalp, face, neck, and shoulders against
splashes, spills, and drips.
 Some hard hats can be modified so you can add face
shields, goggles, hoods, or hearing protection
to them.

Selecting the Right Hard Hat
Class A
 General service (building construction, shipbuilding,
lumbering)
 Good impact protection but limited voltage protection
Class B
 Electrical / Utility work
 Protects against falling objects and high-voltage shock
and burns
Class C
 Designed for comfort, offers limited protection
 Protects against bumps from fixed objects, but does
not protect against falling objects or electrical shock

Hand Protection

9. Md. Akhtar Hossain
Lecturer (CE) KUET
In construction, exposed hands are
susceptible to physical, chemical, and
radiation hazards. Hand protection is
often the only practical means of preventing
injury from
1. physical hazards sharp or jagged
edges on materials and tools, heat, vibration
2. corrosive or toxic chemicals
3. ultraviolet radiation.
Hand Protection

10. Md. Akhtar Hossain
Lecturer (CE) KUET
The nature of the hazard(s), the activity,
and the length of the activity determines the
glove selection. The variety of potential hand
injuries may make selecting the appropriate pair of
gloves more difficult than choosing other
protective equipment. Take care to choose gloves
designed for the particular circumstances of
workplace. Glove manufacturers can provide
valuable assistance.
Material Safety Data Sheets also
provide information on PPE.

Face Protection
 Full face protection
 Protects face from dusts and splashes or
sprays of hazardous liquids
 Does not protect from impact hazards
 Wear safety glasses or goggles underneath

25. Md. Akhtar Hossain
Lecturer (CE) KUET
Eyes need protection from dust, flying debris,
chemical splashes, and foreign objects whether
working in the Construction site.
safety glasses come in as many varieties as
sunglasses but cost much less. Depending on your working
conditions, we carry clear safety glasses, safety sunglasses,
and mirror lens safety glasses. Safety sunglasses can be
like tinted safety glasses, with lenses coming in blue,
amber, green, or red-orange tints.
In a work environment with chemicals, whether in a
professional or educational laboratory, chemical
safety glasses and goggles are recommended. Chemical
safety glasses are made from highly durable frames and
are designed with side shields to protect eyes from minor
chemical splashes.
Eye Safety / Protection

26. Md. Akhtar Hossain
Lecturer (CE) KUET
Engineering controls should be used to reduce
eye injuries and to protect against ocular infection
exposures. Personal protective eyewear, such as goggles,
face shields, safety glasses, or full face respirators
must also be used when an eye hazard exists.
The eye protection chosen for specific work
situations depends upon the nature and extent of
the hazard, the circumstances of exposure, other
protective equipment used, and personal vision needs. Eye
protection should be fit to an individual or adjustable to
provide appropriate coverage. It should be comfortable and
allow for sufficient peripheral vision. Selection of protective
eyewear appropriate for a given task should be made
based on a hazard assessment of each activity,
including regulatory requirements when applicable.

Working at height is generally
believed to be a risky occupation,
therefore anyone involved in working at
heights where there is a risk of a fall which
could cause personal injury must adhere
to strict safety measures. safety
harnesses have all the relevant safety
characteristics you would expect from a
specialist market leader along with the
comfort and freedom of movement to the
worker when using our safety harnesses.

About 1000 construction workers will be killed on
the job this year-about 33% of the fatalities will result from
falls. In general falls cause 15% of all accidental deaths,
and are second only to motor vehicles as a cause of
fatalities.
Each year, falls consistently account for the
greatest number of fatalities in the construction industry.
These types of accidents often involve a number of factors,
including unstable working surfaces, misuse of fall
protection equipment, and human error. Studies have
shown that the use of guardrails, fall arrest systems, safety
nets, covers, and travel restriction systems can prevent
many deaths and injuries from falls.

43. Md. Akhtar Hossain
Lecturer (CE) KUET
Body Wear
Body wear is the personal
protective equipment worn by
the worker, such a full-body
harness . Most regulations
governing fall protection prohibit
the use of body belts for fall
protection due to the concentration
of fall forces on the abdomen.
Full-body harnesses distribute
fall forces throughout the body,
substantially reducing the potential
for injury. In addition, the full-body
harness keeps the worker
suspended upright in the event of
a fall and supported while awaiting
rescue.

44. Md. Akhtar Hossain
Lecturer (CE) KUET
Hearing Protection
In a noisy work environment,
hearing protection is a necessity. Disposable
and reusable earplugs and muffs are
widely used for hearing protection. Noise
Reduction Rating (NRR) that indicates how
powerful the plug or muff will be.

45. Md. Akhtar Hossain
Lecturer (CE) KUET
Protect Your Hearing
As for construction work,
there are many sources
of loud noises. For
example:
 Power saws of various
types.
 Hammers
 Cement trucks and
cement mixers.
 Power & powder
actuated hand tools
 Stapling guns
 Jack hammers and
other cement power tools

When Must Hearing Protection
be Provided?
When an employee’s noise
exposure exceeds an 8-hour time-
weighted average (TWA) sound level
of 90 dB.

47. Md. Akhtar Hossain
Lecturer (CE) KUET
What types of hearing protectors
are available?
Ear plugs
are inserted to block the ear canal. They may be
premolded (preformed) or moldable (foam ear plugs). Ear
plugs are sold as disposable products or reusable plugs.
Custom molded ear plugs are also available.
Semi-insert ear plugs
which consist of two ear plugs held over the ends
of the ear canal by a rigid headband.
Ear muffs
consist of sound-attenuating material and soft
ear cushions that fit around the ear and hard outer cups.
They are held together by a head band.
