II. Computation: (20 points)
San Juan Corporation had an incident involving three workers. All of them received injuries on
their feet, which resulted to 45 days away from work, individually. As of the moment, the
company reached 195,000 man-hours. Calculate the Frequency and Severity Rates. Show your
solution and box your final answers.
No. of Man-hours = 195,000 hrs
No. of Day lost/away = 45 days
No. of Injuries = 3
For Frequency Rate (FR),
FR =
Total No.of disabling injuries x 1,000,000
Employee−hours of Exposure
3 x 1,000,000
Frequency Rate = 15.385
For Severity Rate (SR),
SR =
SR =
Total No.of day lost or charged x 1,000,000
Employee−hours of Exposure
45 x 1,000,000
Severity Rate = 230.769
III.Discussion/Differentiation: (20 points each) 4-7 sentences only
1. Enumerate the Workplace Classification based on Risks, define and give example for
each classification.
 The Workplace Classification based on Risks are; Low risk, Medium risk and High
risk. Wherein the Low-risk workplace, from the word itself refers to a workplace in which
the level of risk or danger that may result to a serious injury was low. It talks about those
who has a less exposure to safety and health hazard which means it has a low level of
danger and less accident, injuries, illness or harm may happen, an example of this was
those who are in the office work or like a time keeper. Next was the Medium risk
workplace which refers to those who are in the workplace but will be expose moderately
to the safety and health hazards and will experience injuries and illness if there is no
control measures or preventive measures are in the workplace. An example of this was the
laborers and skilled workers. Lastly, the High-risk workplace which refers to those who
are in the workplace that expose to a hazard but this time it will affects not only the
workers but even those outside of the establishments, they are highly expose to safety and
health hazard where the accidents are more likely to happen. An example of this was the
mining industry, construction industry and chemical works.
2. How can a safety officer be an OSH Practitioner and OSH Consultant? What are the
minimum requirements?
 To be an OSH practitioner, a safety officer must complete the mandatory 40 hours of OSH
training and an additional of 48 hours of advanced/specialized occupational safety training
course relevant to the industry. Aside from that, it requires at least 2 years of experience
that relevant in OSH and complied the other requirements that was prescribed in the OSH
standards. On the other hand, for a safety officer to be n OSH consultant, he/she also needs
to accomplished both the mandatory 40 and 80 hours of training like the OSH practitioner.
But this time, an additional 320 hours of OSH related training will be needed and an actual
experience as a Safety Officer 3 for at least 4 years. Then if the person will be qualified as
a Safety Officer 4, he/she shall be eligible to be an OSH consultant.
3. As a safety officer in your workplace/jobsite how can you persuade workers who are OSH
skeptics that perceives OSH as just a waste of time and resources?
 As a safety officer who cares about the health and safeness of the workers on my workplace.
If someone was observed that OSH was just a waste of time and resources for them, I will
encourage them to follow OSH by simply asking why are they working and to whom they
are working for? Since I know that most construction workers do their job to sustain the
needs of their family, I’ll expect of having that answer from them. After that, I will tell them
that this OSH was the most important part of their job which will make their family happier
than the money they will be received from all workers. If they ignore the important of the
OSH, I’ll remind them that their family was always waiting for them to go home alive with
no injuries. I’ll tell them that accidents are uncontrolled which may happen to anyone in
anytime as long as we are in the workplace. With that, I’ll tell them that if they really love
their family, then they need to follow the OSH regardless of any opinions they think about
