1/27


2/27

Hierarchy of Safety:

1. ELIMINATE the hazard2. If not practical, PREVENT

3. If not practical, CONTROL


3/27

Classification of Hazards

1. Direct Unguarded machines

Falling / flying materials

Slippery floors, etc.2. Physical

Noise

Temperature extremes Ionizing / non-ionizing radiation

Extreme pressure

Vibration


4/27

Classification of Hazards

3. Chemical Vapors

Gas

Dusts

Fumes

Mists

4. Biological

Bacteria Virus

Fungi

5. Ergonomics


5/27

Last line of

control/defense

2. Administrative Control:

Exposure time limitations

Safe work practices

Alarms and warning signs

Training and education

3. (Point of contact)

Personal Protective

Equipment

Three areas where hazards can be controlled:

SOURCE RECEIVERPATH

1. (Pre-contact) Engineering Control : Elimination/minimization

Enclosure of the hazard

Redirection of hazard


6/27

1. Engineering Controls

If . . .The work environment can be physicallychanged to prevent employee exposure to

existing and potential hazard,

Then . . .The hazard can be eliminated with an

engineering control

Examples . . .

Initial design specifications

Substitute less harmful material

Change processEnclose process

Isolate process


7/27

2. Administrative Controls

If . . .The wayemployees do the job

can be changed, and

exposure to potential

hazard is removed,

Then . . .The hazard

can be eliminated with

administrative control

& others


8/27

3. Personal Protective

EquipmentUse personal protective equipment

(PPE) if the engineering and

administrative controls donteliminate the hazards.

PPE serves as barrier between the

hazard and the worker.

Note: PPE is the last level of control!


9/27

LIMITATIONS OF PPE

Hazard still exists Protection to the wearer only

If the PPE is defective or ineffective,

the user becomes exposed to hazard May introduce additional hazard

May not be suitable for continuoususe

May not be always worn properly

May transfer hazard to anotherlocation


10/27

Training

Why it is necessary

How it will protect them

What are its limitationsWhen and how to wear

How to identify signs of wear

How to clean and disinfectWhat is its useful life & how is it disposed

If employees are required to use PPE, train them:


11/27

PROGRAM TO INTRODUCE PPE

1. WRITTEN POLICY2. PROPER SELECTION OF PPE

assess the workplace to determine ifhazards are present, or are likely to bepresent, which necessitate the use ofPPE

3. PROPER TRAINING

4. MAINTENANCE PROGRAM5. INCENTIVE SYSTEM

6. ENFORCEMENT


12/27

HEAD PROTECTION

HAZARDS:

1. Impact

2. Penetration

3. Absorb shock

4. Electrical

Hard Hat

Bump Cap


13/27

Selecting the Right Hard HatClass 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 CDesigned for comfort, offers limited protection

Protects against bumps from fixed objects, but does

not protect against falling objects or electrical shock


14/27

EYE AND FACE PROTECTION

HAZARDS: Flying particles

Sparks

Light radiation

Splashes Gases

Safety glasses

Safety goggles

Face shields


15/27

EAR PROTECTION

HAZARDS: Excessive Noise

(exceeding 85 90

dB or more on eight

hour exposure

Ear plug

Ear muffs

Canal caps


16/27

Hearing Protection


17/27

Hearing

ProtectionWhen its not

feasible to reduce

the noise or its

duration use earprotective devices

Ear protective

devicesmust be fitted


18/27

When Must Hearing

Protection be Provided? After implementing engineering and

administrative controls

When an employees noise exposureexceeds an 8-hour time- weightedaverage sound level of 85 dBA

Note: Hearing impairment is irreversible.


19/27

RESPIRATORY PROTECTION

HAZARDS:

Mists, vapors,

dusts Gases

Smoke

Fumes

Sprays

Insufficientoxygen supply

Filtration respiratorAir-purifying respirator

Air-supplying respirator


20/27

HAND AND ARM PROTECTIONHAZARDS:

1. Burns2. Bruises

3. Abrasions

4. Cuts

5. Punctures6. Fractures

7. Amputations

8. ChemicalExposures

9. Pinch points10. Hot spots

11. Sharp objects

12. Electrical

GlovesHand pads

Sleeves

Barrier cream


21/27

Buty lprovides thehighest permeationresistance to gas or watervapors

Types of Rubber Gloves

Nitr i leprotects againstsolvents, harshchemicals, fats andpetroleum products andalso provides excellent

resistance to cuts andabrasions.


22/27

Kevlarprotects against

cuts, slashes, and

abrasion

Stainless s teel mesh

protects against cutsand lacerations

Other Types of Gloves


23/27

FOOT AND LEG PROTECTION

HAZARDS:

Fall or rolling

objects

Sharp objects

Hot surfaces

Wet slippery

surfaces

Foot guards/

Safety shoes/boots

Leggings


24/27

FALL PROTECTION

HAZARDS:

Fall from

heights

Safety belts

Safety harness

Lanyards


25/27

TORSO or BODY PROTECTION

HAZARDS:

Heat

Splashes from

hot metal

Impacts

Cuts Chemicals

Radiation

Vests

Jackets

Aprons

Coveralls

Full-body suits


26/27

Cooling Vest Sleeves and Apron

Body Protection

Full Body Suit

PPE in OSHSRULE 1080 - PERSONAL PROTECTIVE

EQUIPMENT AND DEVICES

1081: General Provisions:

1081.01:Every employer (as defined in 1002):

(1)Shall at his own expense furnish his workers withprotective equipment for the eyes, face, hands andfeet, protective shields and barriers whenevernecessary by reason of the hazardous nature of the

process or environment, chemical or radiological orother mechanical irritants or hazards capable ofcausing injury or impairment in the function of anypart of the body through absorption, inhalation orphysical contact.
