– Electric Shock
i d l i i• Live exposed electric wires

Wh i H d P t ti I t t?Why is Head Protection Important?
• In and around your head are:
– Your eyes, with which you see

Hard hats fall into two types and three classes
T i l d• Types include:
– Type 1 - full brim
– Type 2 - no brim, peak extending forward
Cl A l i li it d lt– Class A - general service - limited voltage
– Class B - utility service – high voltage protection
– Class C - special service - no voltage protectionp g p
HARD HAT CLASSES
• Class A. These helmets are for general service.
Th id d i t t ti b t li it dThey provide good impact protection but limited
voltage protection. They are used mainly in mining,
b ildi t ti hi b ildi l b i dbuilding construction, shipbuilding, lumbering, and
• Class B. Choose Class B helmets if your employees
are engaged in electrical work. They protect against
falling objects and high-voltage shock and burns.
• Class C. Designed for comfort, these light-weightg , g g
helmets offer limited protection. They protect workers
from bumping against fixed objects but do not protectp g g j p

• Degradation of thermoplastic material may be apparent
when the shell becomes stiff, brittle, faded, dull in color or
chalky in appearancechalky in appearance.
• Replace at the first sign of any of these conditions
LIFE OF A HARD HAT
• General guideline, replace every five years
regardless of outward appearance
• Exposure to high temperatures, sunlight or
chemicals? Replace every two years
• Inspect suspension as well as shell
• Worksite review is critical to degradation of
