17. Protecting Your Head
Hard hats are required in areas
where injury is possible:
– Impact (bumping head
against objects, such as
pipes or beams)
– Falling or flying objects
– Contact with exposed
electrical wiring
28. 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.
Usually made from aluminum
• Protects against bumps from fixed objects, but
does not protect against falling objects or
electrical shock
Most construction
workers wear type A
29. HEAD PROTECTION
The three classes of hard hats are;
G – General – General service limited voltage
protection – protects your head up to 2,200
volts.
E – Electrical – Utility service high voltage
protection – protects your head up to 20,000
volts.
C – Conductive – Special service – no voltage
protection.

63. FOOT PROTECTION
Class 75 – Protection from a force of 75 foot-pounds
Compression of 2,500 pounds.
Class 50 – Protection from a force of 50 foot-pounds
Compression of 1,750 pounds.
Class 30 – Protection from a force of 30 foot-pounds
Compression of 1,000 pounds.
*Foot-pounds = weight of an object multiplied by the
height at which it is dropped
66. Hand Injuries
A hand injury can ruin your day or your life
Hand injuries include cuts,
burns, fractures,
amputations, nerve damage
and dermatitis.
20% of disabling workplace
injuries involve the hands.
Skin irritation, dermatitis
and even poisoning can
occur by handling chemicals
with bare hands. 3
67. Hand, finger and arm protection
HAZARDS
• Exposure to hot or cold
material and objects
• Bumping into objects
that are sharp or pointed
• Sharp objects and
equipment
68. Hand, finger and arm protection
HAZARDS
• Absorption of chemicals
through skin
• Damage to tissue from
solvents
• Electric shock
73. Butyl provides the
highest permeation
resistance to gas or water
vapors
Types of Rubber Gloves
Nitrile protects against
solvents, harsh
chemicals, fats and
petroleum products and
also provides excellent
resistance to cuts and
abrasions.
74. Chemical-Resistant Gloves
Chemical-resistant gloves facts
Chemical-resistant gloves are
not totally “chemical-proof”
Chemicals will eventually
penetrate the gloves over time.
The thicker the glove, the more
resistant it is to chemicals.
Chemicals will also break down
(swell, crack or weaken) the
glove material over time.
Thick is better than Thin
17
75. Chemical-Resistant Gloves
Chemical glove selection
Good chemical gloves are made of
Viton®, butyl, nitrile, neoprene, or
PVC or combinations of these.
Gloves are selected according
to the type of chemical.
No single glove material will
protect against all chemicals.

76. Chemical-resistant Gloves
Using chemical-resistant gloves
Throw away gloves whenever
degradation is visible or you know
chemicals have leaked inside.
You should know what chemical
you are handling and how long the
gloves will keep the chemical out.
When handling highly toxic chemicals,
two layers of chemical-resistant gloves
can provide additional protection.

80. Glove Use and Care
Use properly fitting gloves that give you
the needed dexterity.
Too big A better fit
Glove Size & Fit
Gloves come in many
sizes.
