OBJECTIVE• To identify three (3) Safety Hazards and two (2) Health Hazards at the workplace and

discuss in detail the techniques used to identify all types of hazards.

• To identify the risk at the workplace

• To reduce the hazard from happen again

• To discuss and give appropriate suggestions for control measures in order to eliminate,

reduce, and minimize the risk of the most critical hazards

• To explain the implications of the most critical hazards (safety & health hazard) that has

been identified and their preventive measure

METHODOLOGY

WORKPLACE HAZARD

OBSERVATION:

• To observe the soil investigation

activities involved and the hazard

encountered during performing the

activities.

• Observe any unsafe act, hazard,

dangerous at the construction site

\INTERVIEW WITH WORKERS

• Interview with safety officer Abdul Razak

Example of question being asking during the interview

as below;

How long you work at this company?

What are the work activities taken until the task is

completed?

Did you notify any hazards occur during each job work

activity?

What are you concern of during the work activity?

REVIEW OF AVAILABLE INFORMATION

• Information were collected from the company

• Reviewing the record of workplace for example document

LIKELIHOOD TABLE

EXAMPLE:

Likelihood

(L)Example Rating

Most likely The most likely result of the hazard / event being realized 5

Possible Has a good chance of occurring and is not unusual 4

Conceivable Might be occur at some time in future 3

Remote Has not been known to occur after many years 2

Inconceivable Is practically impossible and has never occurred 1

SEVERITY TABLE:

Severity Example Rating

Catastrophic Numerous fatalities, irrecoverable property damage and

productivity

5

Fatal Approximately one single fatality major property damage if hazard

is realized

4

Serious Non- fatal injury, permanent disability 3

The worker also has been supplied by complete all ppe . Workers who work at nights are not aware of the hazard

related to the work activity. The effect of the hazard is workers will minor injury, bone fracture, or more badly.

The implication of workers towards nights, the worker might be exposed to accident.

MOST CRITICAL HAZARD (HEALTH HAZARD

This hazard is the most significant critical health hazards because the worker also has been inducted by safety personnel and

provide complete set of PPE. Workers who work with drilling work are not aware of the hazard related to the work activity.

The effect of the hazard workers will get respiratory problem due to drilling sand dust inhalation. The implication of workers

towards drilling sand dust inhalation.

RECOMMENDATION FOR MOST CRITICAL HEALTH HAZARD

No Hierarchy of control Control Measure

1. Elimination

Not applicable

Description:

a) There are nothing can be eliminate in this process

2. Substitution

Not applicable

Description:


3. Isolationa) isolate other worker

Description:

a) Only the person who are involved in drilling works is needed in the area

4. Engineering controla) install the barrier around the work station

Description:

a) To reduce dust from directly exposed to our respirator system

5. Administration controla) Job rotation and frequent short break or provide the work shift for the worker

Description:

a) Job rotation at once in 2 hours,

b) Work shift to workers is necessary

6. Personal Protective Equipment

(PPE)a) Provide respirator (filter mask) goggle, face shield

Description:

a) respirator is needed while drilling the sand for protection of the worker from inhaled the dust

CONCLUSION In order to reduce the hazard or most critical hazard rate, the employer should show commitment

towards safety and health practices and therefore give full priority to promote and enforce the

safety and health rules in workplace.

Hierarchy of control were use in order to minimize and control the most critical hazard that exist at

the workplace.

To ensure the safety culture can be implemented in an organization.

the management and workers have to take part in any safety and health program and give a full

cooperation when comes to safety and health issues.
