Title I
MEDICAL, DENTAL AND OCCUPATIONAL SAFETY
Chapter II
OCCUPATIONAL HEALTH AND SAFETY
Art. 168. Safety and health standards. The Secretary of Labor and Employment shall, by
appropriate orders, set and enforce mandatory occupational safety and health standards to
eliminate or reduce occupational safety and health hazards in all workplaces and institute new,
and update existing, programs to ensure safe and healthful working conditions in all places of
employment.
Page |6
All establishments, workplaces and other undertakings are covered, including agricultural
enterprises whether operating for profit or not, except:
Residential places exclusively devoted to dwelling purposes.
Mines which is under the Department lf Environment and Natural Resources (DENR)
are exempted PRIOR to the effectivity of DO 198.
It means that the worker shall be assured of effective protection against the danger of injury,
sickness or death through safe and healthful working conditions.
The OSH Standards provide that every company shall keep and maintain its workplace free
from work hazards that are likely to cause physical harm to the workers or damage to property.
Thus, the worker is entitled to be provided by the employer with:
Appropriate seats, lighting and ventilation;
Adequate passageways, exits and fire fighting equipment;
Separate facilities for men and women;
Appropriate safety devices like protective gears, masks, helmets, safety boots, coats or
first-aid kits;
Medicines, medical supplies or first-aid kits;
Free medical and dental services and facilities.
The Secretary of Labor and Employment, through the Regional Director or his other authorized
representative, enforces the OSH Standards in the exercise of visitorial and enforcement
powers.

When dominos fall over, each tips the next enough to push it over and continue the process
until all the connected dominos have fallen. However, if just a single domino is removed, the
entire process ceases. Heinrich explains accident causation in the same way:
The second stage, faults of a person, refers to personal characteristics that are conducive to
accidents. For example, having a bad temper may lead to spontaneous outbursts and
disregard for safety. Similarly, general recklessness can also be one of the manifestations of
poor character. Ignorance, such as not knowing safety regulations or standard operating
procedures, is also an example of this stage.
P a g e | 10
The third stage, an unsafe act or condition, is often the beginning of a specific incident. Unlike
the first two stages, which affect the probability of accidents occurring, this stage is closer to
the accident in terms of temporal proximity. This can include a specific act that is unsafe, such
as starting a machine without proper warning, or failing to perform appropriate preventative
actions, such as using guardrails or other safety measures. In essence, this stage entails acts
(or failures to act) that occasionally cause accidents.
The next stage, logically, is the accident itself. This, in and of itself, needs little explanation. It
is, simply, when something occurs that is undesirable and not intended. The final stage, injury,
is the unfortunate outcome of some accidents. Whether an injury occurs during an accident is
often a matter of chance and not always the outcome. This relationship highlights the
relationships between stages in terms of causality. An accident occurring is not a sufficient
cause for an injury, but it is a necessary one. Similarly, the undesirable characteristics in stage
two do not always occur in poor environments, but could not occur without such environments.
Given this necessary causality, the most important policy implication is to remove one of the
dominos (though try for more than one just to be safe); produce a healthy subculture through
positive accident prevention training and seminars, attempt to weed out people with
undesirable characteristics (or otherwise address said traits), and, if all else fails, have a
procedure in place for dealing with accidents to minimize injury and loss.
This "Loss - Causation model" which has been made by Mr. Frank E. Bird, Jr. of the
International Loss Control Institute (ILCI) 2 in the USA was based on an earlier model
developed by Heinrich. This model can be considered a "negative" model since the outcome of
failures in the various phases is loss. As such the model can be used to understand the
various causes leading to accidents and as a framework for accident/incident investigation.
Industrial hygiene is strict and rigorous scientific methodology and often requires professional
experience in determining the potential for hazard, exposures or risk in workplace and
environmental studies.
P a g e | 11
Safety is the state of being "safe", the condition of being protected against physical, social,
spiritual, financial, political, emotional, occupational, psychological, educational or other types
or consequences of failure, damage, error, accidents, harm or any other event which could be
considered non-desirable. This can take the form of being protected from the event or from
exposure to something that causes health or economical losses. It can include protection of
people or of possessions. Or in short, safety is freedom from accidents.
Accident is usually a result of contact of a body with a source of energy above the threshold
limit of the body or structure. It is an occurrence that interrupts the normal and orderly progress
of any activity. Accidents can result to physical harm, damage to property or delay in operation.
Causes of Accidents
➢ Unsafe acts. A violation of safe procedure
• act of omission
• act of commission
➢ Unsafe Conditions. Seen as a physical or chemical property in the material
2. Evaluate = Risk Assessment. Compare what you identified with OSH standards,
3. Correct = Control
➢ PPE. Use protective barrier to protect the worker from the hazard.
Physical Hazards
Control of Noise
1. Engineering methods
Purchase new equipment
Preventive maintenance
Isolation/damping
2. Administrative Control
Job rotation / breaks
3. PPE
Ear plugs / ear muffs
P a g e | 14
Control Methods
1. Engineering Control
Isolation / enclosure / insulation
2. Administrative Control
Shift work, rest periods
Warm food and drinks / medical exams
3. PPE
Thermal clothing / electric blanket
Gloves / cap / jacket / wool lined shoes
3. PPE
gloves, dampers
5. Illumination- is the deliberate application of light to achieve some
aesthetic or practical effect. Lighting includes use of both artificial light
sources such as lamps and natural illumination of interiors from daylight.
Daylighting (through windows, skylights, etc.) is often used as the main source
of light during daytime in buildings given its low cost.
Control Methods
Improve illumination by adding:
artificial light sources
natural light sources
Reduce by:
Isolation or enclosure
PPE
Eye examination
Work in compressed air, for example in pressurized caissons and diving bells, and in diving operations,
may expose people to the risk of decompression sickness.
Control methods
Pre-employment screening
Training (Pre-event)
Scheduled work duration
Exercise (During event)
Medical monitoring
Medications
Pressure vessels / chamber
Rehabilitation (Post-event)
Pressurized suits
P a g e | 16
Chemical Hazards
Chemical Hazard is the danger caused by chemicals to the
environment and people.
Injection
Biological Hazards
Some Biologic Hazards that can are Contiguous or can lead to Death
Tuberculosis- Tuberculosis usually attacks the lungs but can also affect other parts of the
body. It is spread through the air, when people who have the disease cough, sneeze, or spit.
Most infections in humans result in an asymptomatic, latent infection, and about one in ten latent
infections eventually progresses to active disease, which, if left untreated, kills more than 50% of
its victims.
AIDS- This condition progressively reduces the effectiveness of the immune system and leaves
individuals susceptible to opportunistic infections and tumors. HIV is transmitted through direct
contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as
blood, semen, vaginal fluid, preseminal fluid, and breast milk.
Ergonomic Hazards
It is a technique that brings together several disciplines to solve problems at
work.
Risk Assessment
“overall process of estimating the magnitude of risk and deciding whether or not the
risk is tolerable”
Tolerable Risk
“risk that has been reduced to a level that can be endured by the organization
having regard to its legal obligations and its own OH & S policy”
In simple terms, the risk from the hazard should be determined by estimating
Severity of harm
Likelihood of harm occurring
Severity of Harm
Slightly Harmful Superficial injuries, Nuisance, Irritation, ill-
health leading to temporary discomfort
Likelihood of Harm
Highly Unlikely Occurs during accident, breakdown or
emergency situation.
Unlikely Occurs during regular scheduled practice i.e.
monthly or yearly e.g. during maintenance.
Likely - Occurs during normal everyday practice.
What is Risk?
“The combination of the likelihood and the consequences of a specified hazardous
event (accident or incident)”
P a g e | 21
Consequences
Minor First Aid Treatment
Medium Off-site medical treatment required
Serious Serious injury/illness
Major Permanent disability

Legend:
L Low Risk – considered acceptable. No further action of RCMs are necessary
M Moderate Risk – relatively acceptable. However, further RCMs should be considered and existing RCMs
should be monitored
H High Risk – unacceptable level of risk. RCMs must be developed and implemented in short to medium
term
E Extreme Risk – unacceptable level of risk. RCMs must be immediately implemented or the risk
eliminated (i.e case activity)
P a g e | 23
MANAGE FOR CONTINUOUS IMPROVEMENT – is an area where the risk is low and the existing H & S
arrangements is adequate
INCORPORATE RISK REDUCTION MEASURES – where the frequency and severity is fairly high and warrant
specific risk reduction measures, such as the use of procedures for controlling the risk or making hardware
improvement
INTOLERABLE – where the number of incidents and the severity are clearly intolerable and warrant a H & S Case
MANAGEMENT OF RISK
Based on the results of the risk assessment the organization must now decide if:
No action required
No additional controls required
Efforts to be made to reduce the risks
Work should not be started or continue until the risks have been reduced or
urgent action required
Accident- Unplanned, undesired event, not necessarily injurious or damaging, that disrupts
the completion of an activity.
Hazard- Is any potential or existing condition in the workplace that, by itself or by interacting with
other variables, can result in death, injuries, property damage, and other losses.
Hazard Control- Hazard control involves developing a program to recognize, evaluate, and
eliminate (or at least reduce) the destructive efforts of hazards arising from human errors and from
conditions in the workplace.
Loss Control- Is accident prevention, achieved through a complete safety and health control
program.

Points on Safety Storage of Materials
________________________________________________________________________________
1. Materials that can react with each other should be stored in separate areas (e.g. acid
and base)
_______
2. Storage areas should be well ventilated and lighted
3. In storage areas of flammable materials, explosion proof lighting fixtures and switches
to be used
4. Fire extinguishers should be sufficient for the amount and the type of materials in the
storage area. Fire Extinguishers should be accessible.
5. Adequate spacing for access (at least 4 feet of space from any structure or shelf)
6. Compressed gas (high-pressure) tanks and cylinders should be stored in upright
position and should be secured with ropes, slings or chain to a rigid structure.
7. No open flame work near the storage of combustible and flammable materials. Hot
work permit is mandatory should welding is extremely necessary.
P a g e | 27
B. Mechanical Safety
Guarding, or machine guarding, is often thought of as being concerned only with points of
operation or with the means of power transmission. Although guarding against these hazards
is required, this step can also prevent injuries from other causes both on and around machines
and from equipment and damaged materials. Poor machine guarding practices are one of the
greatest contributors to workplace injuries. Guarding or barriers may prevent injuries from the
following sources:
Principles of Safeguarding
Point of Operation- the point in the machine where work is performed on the
material
o Cutting, Shaping, Boring or Forming Stock
Power Transmission- All components of the mechanical system which transmit
energy to the part of the machine performing the work.
o Flywheels, Pulleys, Belts, Couplings, Gears
Other Moving Parts- All parts of the machine which moves while the machine
is working
o Reciprocating, Rotating, and transverse moving parts
P a g e | 29
Prevent contact - prevent worker’s body or clothing from contacting hazardous moving
parts
Protect from falling objects - ensure that no objects can fall into moving parts
Create no new hazards - must not have shear points, jagged edges or unfinished
surfaces
Create no interference - must not prevent worker from performing the job quickly and
comfortably
Allow safe lubrication - if possible, be able to lubricate the machine without removing
the safeguards
Guards
Devices
Location/Distance
Feeding & Ejecting Method
Miscellaneous Aids
Fixed Guard
Provides a barrier - a permanent part of the machine, preferable to all other types of guards.
Interlocked Guard
Bandsaw
Adjustable Guard blade
adjustable
guard
Provides a barrier which may be adjusted to facilitate a variety of
production operations.
P a g e | 30
Self-Adjusting Guard
Pullback Device
• Die closed
Restraint Device
Two-Hand Control
• Requires constant, concurrent pressure to activate the machine
• The operator’s hands are required to be at a safe location (on
control buttons) and at a safe distance from the danger area while
the machine completes its closing cycle
Presence Sensing
Uses systems of light.
Principle of operation: When the light beam is broken, machine will not start to cycle or
stopping mechanism will be activated.
Gate
• Movable barrier device which protects
the operator at the point of operation
before the machine cycle can be
started
• If the gate does not fully close,
machine will not function
Safeguarding by Location/Distance
• Locate the machine or its dangerous moving parts so that they are
not accessible or do not present a hazard to a worker during normal
operation
• Maintain a safe distance from the danger area
Automatic Feed
(shown on
power press)
P a g e | 32
Robots
• Machines that load and unload stock, assemble parts, transfer objects, or perform other
tasks
• Best used in high-production processes requiring repeated routines where they prevent
other hazards to employees
Protective Shields
These do not give complete protection from machine hazards, but
do provide some protection from flying particles, splashing cutting
oils, or coolants.
Holding Tools
• Used to place and remove stock in the danger area
• Not to be used instead of other machine safeguards, but as a
supplement
Training
Operators should receive training on the following:
• Hazards associated with particular machines
• How the safeguards provide protection and the hazards for which they are intended
• How and why to use the safeguards
• How and when safeguards can be removed and by whom
• What to do if a safeguard is damaged, missing, or unable to provide adequate
protection
C. Electrical Safety
Resistance- The property of material that opposes the flow of electric current (measured in
ohms)
Ohm’s law- the current flowing in a circuit is directly proportional to the voltage and inversely
proportional to the resistance.
Conductor- permits electrons or electric current to flow through it Conductors have low
resistance to electricity and are used for wires, switches and electrical connections.
Insulator- Used to provide barrier around a conductor (to prevent accidental contact).
Insulators have a very high resistance to the flow of electricity and are used to cover wiring and
other electrical components
Any part of your body that accidentally bridges the gap between two different voltage levels
creates a new electrical circuit, and your body may provide the path of least resistance to the
ground. Equipment grounding connects all conductive materials that enclose electrical lines.
Bypassing grounds or careless handling of grounding connections can result in electrical fires
and fatal accidents
Electrical Shock – is the most serious electrical hazard. This happens when you touch a live
wire, a tool or machine with poor insulation. You then become a conductor. The danger of an
electric shock is not directly related to the voltage, but mainly determined by the following
conditions: current value, type of power supply, duration of electric shock, passage of current
and human condition.
The minimum current at which a man feels an electric shock is about 1 mA at 60Hz;
the limit current at which man can endure the pain of an electric shock is about 7 to
8 mA and the maximum current at which man can still move is about 10 to 15 mA.
The heart is particularly the susceptible to electric shock. The flow of the current
disturbs the hearts rhythm, upsetting the blood flow and affecting its vital
functions. When the current increases, the heart shivers and death results in few minutes.
Lockout - is blocking the flow of energy from the power source to the equipment-
and keeping it blocked out.
Lockout/ tag out protects you from the unexpected start-up of machines or
release of stored energy during service or maintenance.
D. Fire Safety
Fire is the result of the chemical combination of a combustible material (fuel) with oxygen in
the presence of enough heat. If any one of the three is missing, a fire will not start. The
relationship is called fire triangle. It is important that every worker, not only supervisor, knows
the main causes of fire, how fire spreads, how to fight
fire, and how to prevent fire.
****************************************************************************************************
Oxygen levels can be reduced below the minimum (16%) percentage needed for combustion
by purging and rendering the atmosphere inert in closed containers or processing systems.
Cooling or heat source control. The most common means of fire. Water is the most
effective and cheapest medium for fighting a fire.
Class C fires involve energized electrical equipment. This class of fire can be
controlled by the use of non-conducting extinguishing agents. The safest procedure
P a g e | 38
is to always de-energize high voltage circuits and treat as Class A or Class B fire
depending on the fuel.
Class K fire or kitchen fire. Fires that involve cooking oils or fats are
designated "Class K" under the US system, and "Class F" under the
European/Australasian systems. Though such fires are technically a subclass of the
flammable liquid/gas class, the special characteristics of these types of fires are
considered important enough to recognize separately.
Fire Extinguishers - Is an active fire protection device used to extinguish or control small
fires, often in emergency situations. This is the first line of defense. Fire extinguishers are
further divided into handheld and cart-mounted, also called wheeled extinguishers.
Handheld extinguishers weigh from 0.5 to 14 kilograms (1 to 30 pounds), and are hence,
easily portable by hand. Cart-mounted units typically weigh 23+ kilograms (50+ pounds).
These wheeled models are most commonly found at construction sites, airport runways,
heliports, as well as docks and marinas.

P a g e | 41
HAZARD IDENTIFICATION
There must be a determination of all-possible events or processes that could
lead to hazardous incidents. It must involve the definition of inherent and
potential hazards of the substances and processes identified in the impact
assessment. For a thorough risk analysis, it is imperative that necessary data
are available and considered. This may involve the review of the present plant
layout; equipment layout; inventories of hazardous substances; equipment
control parameters; materials safety data sheets (physical and toxicity data);
operating procedures; safety practices and emergency procedures.
HAZARD ACCOUNTING
There must be a list of all existing hazards in the workplace stating how they are
used, processed, disposed off, interact with other processes, behave and
handled.
The system boundaries must be identified with inputs from different groups and
establish priorities as to which hazards need to be evaluated first and identify
linkages that would lead to a cost-effective mitigating measure. The
geographical limits of management interest, time concerned, population groups
to be protected, and the kinds of impacts to be assessed could indicate the
system boundaries.
PATHWAY EVALUATION
There must be an evaluation of the effect of the various routes or exposure to a
person or an ecosystem. The linkage between initiating events or initial
conditions, and the eventual impacts on human health, welfare and ecosystem
must be evaluated. The Fault Tree (Causes) Analyses and Event Tree
(Consequences) Analyses is suggested, to be used in a complementary manner
to provide a more quantitative accident scenario evaluation.
RISK CHARACTERIZATION
Risk must be estimated of the frequency and severity of adverse effects. The
results must be presented in a form useful to management to manage risks.
Risk analyses must be expressed in a quantitative and qualitative manner and
evaluated according as to its priority index (Risk = probability x severity). The
use of an environmental risk matrix with reference to environmental components
can be used to summarize the characterization of risks.
P a g e | 42
RISK ANALYSIS
Priority risks that were identified must be evaluated for adequacy and
completeness. The risk assessment must include scope of boundaries,
appropriateness of methods used to characterize risks, reasonable
assumptions; level of participation of affected parties, degree of uncertainties in
risk estimates and extent of the set of risk scenarios. Risk analysis will also
provide information for emergency and contingency planning. There must be
risk analysis for environment, safety and health.
RISK MANAGEMENT
The information provided by the risk evaluation process will be the basis for risk-
reduction actions or most appropriate alternatives that appear cost-effective.
The organization must identify the necessity of these reduction measures to
their operation, whenever applicable, based on the performed risk analysis.
Again, the overall risk management program must cover environment, safety
and health risk.
IMPLEMENTATION
The identified environment, safety and health risk program must be
implemented in every activity or areas determined to have unacceptable risk
scenarios. The application of cost-effective measures to ensure a reduction of
the risk to acceptable level must be in place and already applied.
EVALUATION
There must be an evaluation on the effectiveness of the risk management
program. This is to ensure that the objectives and targets are met within the
designed timeframe. The evaluation will also provide the opportunity to improve
ineffective corrective and preventive actions. The person responsible for the
complete implementation and monitoring of the risk management program must
prepare the performance evaluation report and to be submitted to top
management for review.
P a g e | 43
DISASTER is sudden, calamitous event bringing wide spread damage or suffering, loss or
destruction and great misfortune, often arriving without forewarning.
FIRST AID – is the immediate care given to a victim who has been injured or suddenly taken
ill.
1. Serves as the bridge that fills the gap between the victim and the physician.
2. He is not to compete with nor take the place of the physician.
3. He will assist the physician when he arrives.
EVACUATION
On hearing the alarm signal, gather vital personal effects and go for the nearest exit
near you.
Go to the assembly area at the open field assigned near your present location
If you are away from normal work floor, obey instructions from that floor.
Do not attempt to return to your own floor
Security will take any other action.
BOMB THREAT
If a bomb or suspicious object is discovered – do not touch it, clear the area
Notify security office
Prevent other personnel from going into the area
Security will take any other action required
