Md. Tanvir Hossain presented on head protection in construction sites. The presentation covered causes of head injuries such as falling objects or debris, striking fixed objects, and electrical hazards. Without head protection, injuries can range from permanent disfigurement to death. Hard hats are classified by type, providing protection to just the top of the head or the top and sides, and by class based on impact resistance and electrical insulation. The presentation recommended always wearing the proper class of hard hat for the work being done to minimize risks to the head, the most sensitive part of the body.

Head Protection in a construction site
Welcome to Presentation
Course Tittle: Professional Practices & Communication Sessional
Course code: CE408

2. Presentation Outcome
 Head protection & statically view
 Causes of head injuries
 Problems created in lack of head protection
 Classification of head protection Equipment
 Recommendation

3. HEAD PROTECTION
In a construction site, avoidance of head injuries through risk
assessment and application of appropriate measures is may
be defined as head protection

4. Statically Possibility of Head Injury among various hazard
Contact with
equipment or falling
object
35%
Trapped by something
collapsing or over
turning
21%
Stack by moving
vehicles
10%
Contract by electricity
or electrical discharge…
Contract with moving
machinery or material
being machined
4%
sleep and falls
25%
Contact with equipment or falling object
Trapped by something collapsing or over turning
Stack by moving vehicles
Contract by electricity or electrical discharge
Contract with moving machinery or material being machined

5. Causes of head injuries
# When objects or debris might fall
from above and strike workers on
the head
# When employees may strike their
heads against fixed objects, like
supports, beams, or other equipment
# When there is the possibility that
workers’ heads will make contact
with electrical hazards

6. Problem created In lack of head protection
Wearing head protection should never be ignored on a construction site to
prevent the destruction
• Permanent disfigurement
• Deafness
• Blindness
• Loss of mobility
• Loss of control of bodily functions
• Mental retardation
• Death

7. Hard hats are not magical to prevent an injury, but it
will definitely minimize the impact of an accident
A Bureau of Labor Statistics (BLS)
survey shows that workers who suffered
head injuries at Construction sites did not
wear head protection at the time of the
accident

8. Requirements of a good Safety Helmet
 To ensure that a hard hat is undamaged
 does not have any dents, cracks , or holes resulting from impact
 have a good enough suspension system inside it.
 Do not cover with a multitude of labels and stickers.
 also provide protection against electricity and heat.

9. Classifications of Helmets
According to ANSI (American National Standard for Industrial head protection) There are two types and three classes of
Head safety Helmets.
– TYPES OF HELMETS
– Type I - Provides protection to the top of the head
– Type II – Provides protection to the top and sides of the head

10. Classes of Helmets
 Class A Helmets must reduce:
the impact force of a falling object.
Provide Limited voltage protection ,Helmets are tested
220 volts.
 Class B Helmets must reduce:
the impact force of impact of a falling object
Provide high voltage protection , Helmets are tested at
2000 volts.
 Class C Helmets:
must reduce the impact force of a falling object.
are not to provide electrical protection.

11. RECOMMENDATION
• Head is the most sensitive part of human body. We have to aware of the right type of head
protection that we should be using at the construction site.
• There is a proverb in bangla (একটি দুর্ঘটনা সারা জীবননর কান্না ) so as a bangali engineer we
should consider the highest security of all types of protection issue in construction site.
