6- Planning:

Define future goals.


Activation, control, and analysis of plans and objectives.

Hazards people face at work, including chemical, biological, psychological, and physical hazards. They may include injuries as short-time hazards, while long-term ones may evolve to cancer and heart disease.

9- Identify and limit all hazards and determine the manner of control:

Identify and limit all expected hazards, determine the method of controlling them appropriately, and provide all tools and tasks that control and reduce the risk.

10- Identify critical risks:

Any activity that may cause injury or danger, leading to partial or total disability or death is considered a critical risk that must be controlled and observed.

11-Health and Safety Officer:

The person responsible for planning, implementing, analyzing, preserving and documenting the system. He also has all the powers and authorities that enable him to perform his functions appropriately and correctly.

12- Quality Control Documents:

Specifications, standards, plans, objectives, samples, and records previously set.

13-Data Analysis

To measure the performance of what has been implemented with what has been previously planned to find out the causes of any differences compared to the planned implementation to reduce or eliminate them, and to know the strengths and weaknesses.

14-Activity Observation and Follow-up

Assure that activities conform to the previously set plan.


 The activity meets the specifications and standards that have been previously set.


The activity does not meet the standards and specifications that have been previously set.

17-Control of Non-conforming Activity:

Follow the appropriate process to correct an activity or activities that has/have been misdirected.

18- Specifications and Standards:

A set of rules that regulate OHSMS activity for the benefit of all concerned parties.

Note- The specification and standards can be required by a government, a client, or specific standards of an establishment or other.

 19-Calibration and Maintenance of Tools, Equipment, and Machines:

Calibrate tools, equipment, and machines used in any facility, which may also affect health and safety.
 This item can be excluded for establishments that do not use measuring tools that affect health and safety.
Use a catalog of the tool or machine used to determine whether or not it requires calibration.
Follow the safety instructions of equipment and machines.
The establishment administration must provide physical evidence to show the intention of implementing the calibration and maintenance.

20- Basic Phases of Occupational Health and Safety Control:

Before working: Assure applying safety instructions before starting to work.
During work:  Monitor commitment to follow safety instructions during work.
After work: Monitor applying safety instructions after finishing working.
The facility management shall identify, plan, implement, and analyze the phases of following safety instructions to assure the health and safety of all workers and properties.

21-Work Instructions:

Create work instructions to assure safety in activities affecting the health and safety of the facility’s workers, for example: instructions for forklifts, mining equipment, winches, first aid, visitors, administrator or computer workers, office workers, workers in high places, or instructions for closed places, etc.

22- Testing and Inspection:

Assurance of the extent to which the tools, equipment, and safeguards conform to the specifications and standards that have been set before using them.

23-Protection Tasks:

Anything that helps to keep workers safe is a protection task.
(Protective clothing – firefighting missions – alarms – instructional panels – first aid)

24- Work Environment:

 Provide a suitable work environment and free from occupational and health dangers. It shall be safe, clean, and ventilated.

25- Environmental Measurements:

Take environmental measurements suitable for the nature of the activity in the facility.
Such as: suspended impurities – light intensity – noise intensity – heat stress.

26-Infection Control:

Take appropriate precautionary measures to reduce the risk of transmitting infectious diseases among the facility’s workers.

27- Training and Awareness

Train all employees on how to deal with risks (fire- Escape and evacuation rules-injuries).
Training certificates must be issued internally or externally after training.

28- Top Management:

It`s responsible for providing all requirements of the occupational health and safety management system. It documents the appropriate decisions and recommendations to reduce and prevent hazards in cooperation with the occupational health and safety officer.
