INTRODUCTIONHead injuries causes include– Impact
• Falling or flying objects• falling or walking into hard objects• injuries include neck sprains concussions and skull• injuries include neck sprains, concussions, and skull
fractures– Electric Shock
i d l i i• Live exposed electric wires• Injuries include electrical shocks and burns
– Dripsp• Toxic liquids such as acids, caustics, and molten metals can
irritate and burn the head/scalpHard hats:Hard hats:– resist penetration– absorb the shock of a blowabsorb the shock of a blow– lessen injury

TYPES 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
Classes include:Cl A l i li it d lt– Class A - general service - limited voltage protection
– 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 manufacturing.
• 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-weight g , g ghelmets offer limited protection. They protect workers from bumping against fixed objects but do not protect p g g j pagainst falling objects or electric shock.

PROTECTION
• Suspension system inside acts as a shock• Suspension system inside acts as a shock absorber
• Some hats serve as an insulator against electrical shocksg
• Shields your scalp, face, neck, and shoulders against splashes spills and dripsshoulders against splashes, spills, and drips
• Some can be modified so you can add face shields, goggles, hoods or hearing protection

MAINTENANCE
• Best to wear ANSI approved hard hatpp• Hats consist of two components: shell and suspension• Components work together as a system and must beComponents work together as a system and must be
inspected on a regular basis• Shells should be inspected for dents, cracks, gouges & any p , , g g y
damage from impact, penetration, abrasions, rough treatment or wear.
• 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
PPE
