A
safety helmet (hard hat) is a type of helmet predominantly used in workplace
environments such as industrial and construction sites. The helmet is used to
protect the head from injury due to falling objects, impact with other objects,
rain, and electric shock. Suspension bands inside the helmet covered the
helmet’s weight and the force of an impact over the top of the head. A
suspension gives space of roughly 30 mm between the helmet’s shell and the
person’s head.  The force of the object is
less likely to be transferred straight to the skull If an object hits the
shell. Some hardhat shells hold a mid-line reinforcement backbone to enhance
impact protection.

A
study among USA workers shows that although 20 million people use safety helmet
while working. 1500 of accidents are fatal among the 120,000 on-the-job head
injuries to happen each year. The American National Standards Institute (ANSI)
developed its performance standards for safety helmets.  Moreover, safety helmets must be properly cared
for to guarantee their lasting effectiveness to satisfy manufacturing
specifications. One essential for ANSI approval is that a guidance booklet is
provided with each safety helmet, describing how to care for the helmet, how to
examine it for indications of damage, and how to make certain it matches
perfectly. A safety helmet should be replaced after five years of use even
though there are no damages in the helmet.

A
safety helmet needs to fit ANSI Z89.1 is OSHA compliant. 29 CFR 1910.135(b)(1)
and 29 CFR 1926.100(b)(1) state that head protection must reach 1997, 2003, or
2009 editions of ANSI Z89.1, or be shown to offer similar or better protection.

Use of Safety Helmet

Safety
helmet should be used when falling object hazards may occur from activities
with closeness to:

·        
persons or operations where accidental
dropping of tools and equipment could drive to a head wound

·        
a blocked destruction or construction
area where head hazards exist.

·        
things stocked on shelves or
platforms  that may fall and cause a head
injury.

·        
overhead exposed energized conductors
nearby.
