TYPES OF HARD HAT
Type I- hard hats
that are intended to reduce the force of impact
resulting from a blow to the top of the head.
Type II- hard hats
are intended to provide protection against both side
impact and blows to the top of the head.
INDUSTRIAL CLASSES OF HARD HAT
Class G - provide
impact and penetration resistance along with limited
voltage protection up to 2,200 volts.
Class E - provide
impact and penetration resistance and protection against
electrical hazards, with high voltage shock and burn
protection up to 20,000 volts.
Class C - provide
lightweight comfort and impact protection but offer no
electrical protection from electrical hazards. |

TYPES OF PROTECTIVE GLOVES
Leather gloves -
protect against sparks, moderate heat, blows, chips and
rough objects.
Aluminized
gloves- provide
reflective and insulating protection against heat.
Fabric gloves -
protect against dirt, sliver, chafing and abrasions.
Chemical-resistant gloves -
protect against exposure to harmful chemicals and
substances.
 |
Latex gloves -
are made of natural rubber,
comfortable to wear and protects hands from most
water solutions of acids, alkalis, salts and
ketones. |
 |
Neoprene gloves
- are made of synthetic rubber and offer good
pliability, finger dexterity, high density and
tear resistant. They protect against hydraulic
fluids, gasoline, alcohols, organic acids and
alkalis. |
 |
Nitrile gloves
- are made of a copolymer and provide protection
when working with oils, greases, acids, caustics
and alcohols. |
 |
Butyl gloves
- are made of synthetic rubber and protect
against a wide variety of chemicals, such as
peroxide, highly corrosive acids, strong bases,
alcohols, aldehydes, ketones, esters and
nitrocompounds. |

Hazards exist in every workplace in various
different forms. Hazardous chemicals, noise, flying
sparks, falling objects and other potentially
dangerous situations.
Employers are required to protect their employees
from these workplace hazards through the use of engineering
controls or
safety work procedures. When these controls are not
feasible or do not provide sufficient protection, the
use of Personal Protective Equipment (PPE) is required.
Employers are required to assess the workplace to
determine if there are hazards present, or are likely to be
present, in the workplace which necessitates the use of PPE. If employees
are required to use PPE, employers must establish general procedures,
called a PPE Program, to
provide employees necessary protective equipment and to
train them to use it properly. The program should
explain when to use PPE and how to select, maintain and
evaluate it.
Employer's Responsibility:
- Perform hazard assessment of
the workplace to identify and control physical and
health hazards.
- Uses engineering controls and safe
work procedures to eliminate or reduce hazards before using PPE.
- Selects and provide appropriate PPE to
protect employees from hazards that cannot be
eliminated.
- Train employees in the use and care of the PPE.
- Maintain PPE and replace damaged or worn PPE.
- Review, update and evaluate regularly the
effectiveness of the PPE program.
Employee's Responsibility:
- Properly wear appropriate PPE.
- Attend training sessions on PPE.
- Care, clean and maintain PPE.
- Inform supervisor of the need to repair or
replace damaged or worn PPE.

EYE AND FACE PROTECTION
Employers are required to provide employees with
appropriate eye or face protection if they are exposed
to eye or face hazards from flying particles, liquid
chemicals, acids or caustic liquids, molten metals,
chemical gases or vapors, potentially harmful light
radiation or potentially infected materials.
Guidelines in selecting the most suitable eye and
face protection:
 |
Should be able to effectively protect against
specific workplace hazards. |
 |
Should fit properly and be reasonably comfortable to
wear. |
 |
Should provide unrestricted vision and movement. |
 |
Should be durable and cleanable. |
 |
Should not interfere with the normal functioning of
any other required PPE. |
Types of Eye and Face
Protection
 |
Safety Glasses -
protective eyewear made of metal or plastic
frames and and impact resistant lenses. Equipped
with side shields or wraparound design to protect
the eyes from the side. |
 |
Safety Goggles
- protective eyewear that completely covers the eyes
and facial area immediately around the eyes and
provide protection from impact, dust and splashes. |
 |
Welding Mask -
a full face protection made of fiber
glass or vulcanized fiber and fitted with a filtered
lens, welding shields. Welders mask protect the eyes
from burns caused by infrared and intense
radiant light and protects both eyes and face from
flying sparks, metal spatter and welding slag. |
 |
Face Shields
- a full face protection made of transparent plastic
and protects both eyes and face against nuisance
dust, flying particles and chemical splashes. Face
shield does not provide protection against impact
hazards and must be used in combination with safety
glass or safety goggles. |
|
|
 |
| |
HEAD PROTECTION
Employers must ensure that their employees are protected
from head injuries if: (1)
there are objects in their work area that might
fall from above or strike them on the head,
(2) they might bump their heads against fixed
objects and, (3)
there is a possibility of accidental head contact with
electrical hazards.
Guides in selecting the most head protection:
 |
Should resist penetration by objects. |
 |
Should absorb the shock of a blow. |
 |
Water resistant and slow burning. |
 |
Should have provisions for adjustments to ensure
proper fit and comfortable use. |
|
|
 |
| |
HAND AND ARM
PROTECTION
Employers must ensure that their employees wear
appropriate hand and arm protection if a workplace
hazard assessment reveals that employees face potential
injury to the hands and arms that cannot be eliminated
through engineering and work practice controls.
Potential hazards
include skin absorption of harmful substances, chemical
or thermal burns, electrical dangers, bruises,
abrasions, cuts punctures, fractures and amputations. |
|
| |
 |
|
| |
BODY PROTECTION
Employees who face possible bodily injury of nay kind
that cannot be eliminated through engineering, work
practice or administrative controls, must wear
appropriate body protection while performing their jobs.
Potential hazards
include temperature extremes, hot splashes from molten
metals, hot splashes from hot liquids, potentials impact
from tools, machinery and materials and contact of
hazardous and toxic chemicals. |
|
| |
 |
|
| |
HEARING PROTECTION
if engineering and work practice controls cannot
effectively lower employee exposure to workplace noise
to acceptable levels, employees must wear appropriate
hearing protection.
Types of Hearing Protection
 |
Single use earplugs -
are made of waxed cotton, foam, silicone rubber
or fiberglass wool. They are self-forming and, when
inserted properly, they work as well as most molded
earplugs. |
 |
Pre-formed or molded
earplugs
- must be individually fitted by a professional and
can be disposable or reusable. |
 |
Earmuffs -
require a perfect seal around the ear. |
