10 Examples of Workplace Hazards and How to Control Them
Occupational Health and Safety (OHS) is an essential aspect that every company must prioritize. A safe work environment not only protects workers from occupational accidents and illnesses but also helps improve productivity and smooth company operations.
One of the vital steps in implementing OHS is recognizing various potential hazards in the workplace and knowing how to control them. Hazards can originate from machinery, chemicals, the work environment, human activities, or unsafe work systems.
If not appropriately controlled, these potential hazards can lead to workplace accidents, equipment damage, health disorders, and even death.
So, what are some examples of workplace hazards, and how can they be controlled? Read the following explanation.
What is a workplace hazard?
A workplace hazard is anything that has the potential to cause injury, occupational illness, equipment damage, or disruption to the safety and health of workers.
In the application of Occupational Health and Safety (OHS), it is important to distinguish between hazards and risks.
Hazard is a source, situation, or action that has the potential to cause injury or ill health.
Risk is a combination of the likelihood of a hazardous event occurring and the severity of the consequences it may cause.
For example, an exposed electrical cable is a hazard. Meanwhile, the risk that may arise is a worker getting electrocuted when touching the cable.
Therefore, companies need to systematically conduct hazard identification, risk assessment, and risk control.
10 Examples of Workplace Hazards and How to Control Them
Here are ten common examples of hazards found in various work environments, ranging from offices, factories, and warehouses to construction projects.
1. Physical Hazards: Physical hazards originate from environmental factors in the workplace that can affect the safety and health of workers. Examples include:

Providing reporting mechanisms for conflicts, bullying, and harassment.
Providing support to workers experiencing work pressure.
Evaluating organizational factors that can cause stress.
Controlling psychosocial hazards requires the involvement of management, supervisors, and workers to build a healthy and mutually respectful work environment.
How to Control Workplace Hazards?
Recognizing hazards is the first step. For controls to be effective, companies need to apply a systematic approach. One approach that can be used is hazard identification and risk assessment through the HIRADC (Hazard Identification, Risk Assessment, and Determining Control) method. Generally, the steps include:
1. Hazard Identification: Inspect all work activities to identify potential hazards that may arise. Identification can be done through:
Workplace inspections.
Observation of worker activities.
Interviews with workers and supervisors.
Review of accident and near-miss records.
Evaluation of equipment, materials, and work procedures.
2. Risk Assessment: Once hazards are identified, assess the likelihood of a hazardous event occurring and the severity of its impact. The assessment results help the company determine control priorities, especially for the highest risks.
3. Apply the Hierarchy of Risk Controls. Risk control should follow the hierarchy of controls below, from the generally most effective to the most reliant on worker behavior.
Elimination: Removing unnecessary hazardous activities.
Substitution: Replacing hazardous chemicals with safer alternatives.
Engineering Controls: Installing machine guards or local ventilation systems.
Administrative Controls: Creating SOPs, restricting access, and providing training.
Personal Protective Equipment (PPE): Using safety helmets, gloves, or hearing protection according to the hazard.
4. Conduct Monitoring and Evaluation: Hazard controls must be checked periodically to ensure their effectiveness. Monitoring can be done through OHS inspections, internal audits, evaluation of SOP compliance, work environment monitoring, as well as incident and near-miss analysis. If ineffective controls are found, the company needs to take corrective actions and re-evaluate the existing risks.
Regulations Related to Workplace Hazard Control
In Indonesia, the implementation of OHS has a legal basis that companies must observe. Some relevant regulations include:
Law Number 1 of 1970 concerning Occupational Safety: Regulates the basic provisions of occupational safety.
Government Regulation Number 50 of 2012 concerning the Implementation of Occupational Health and Safety Management Systems (SMK3): Regulates the application of SMK3 for companies that meet the criteria in the regulation.
Minister of Manpower Regulation Number 5 of 2018 concerning Occupational Health and Safety in the Work Environment: Regulates OHS aspects within the work environment.
The application of these provisions needs to be adjusted to the characteristics of business activities, potential hazards, and other technical regulations applicable to each sector. Companies should check the validity status and the latest provisions through official government sources before using a regulation as a basis for internal procedures.
Conclusion
Workplace hazards can originate from various sources, ranging from physical, chemical, biological, ergonomic, mechanical, and electrical factors to fires, work area conditions, working at heights, and psychosocial factors. Every hazard has different characteristics and potential impacts, requiring appropriate control methods.
Through hazard identification, risk assessment, application of the hierarchy of controls, and periodic evaluations, companies can reduce the likelihood of workplace accidents and occupational illnesses. The implementation of Occupational Health and Safety (OHS) is not only the responsibility of OHS officers but requires management commitment and the participation of all workers. With a strong safety culture, companies can create a safer, healthier, and more productive work environment.
