MatKul K3 : Konsep Bahaya & Risiko

Summary

This video, part of an occupational health and safety course, explains the concepts of hazards and risks in the workplace. It defines hazards as potential sources of harm, which may affect workers, property, or the environment. Hazards are categorized into five types: physical, chemical, biological, ergonomic, and psychosocial. The video also discusses how risks emerge when workers are exposed to hazards, with varying probabilities and impacts. Understanding these risks helps create a safer and healthier work environment. The video encourages further exploration of the topic through additional resources and group assignments.

Takeaways

• ⚠️ Understanding of hazards and risks is essential for creating a safe, healthy workplace environment.
• 🔍 Hazards are situations or sources with the potential to cause harm or loss, such as accidents or illnesses.
• 🧱 Hazards are categorized into five main types: physical, chemical, biological, ergonomic, and psychosocial.
• 🔊 Physical hazards include noise, heights, pressure, electrical currents, vibrations, and radiation.
• 🧪 Chemical hazards come from substances that can irritate or harm the body, such as solids, liquids, and gases.
• 🦠 Biological hazards are caused by microorganisms or living beings like bacteria, viruses, insects, or animals.
• 🛠 Ergonomic hazards arise from mismatches between workers' abilities and the work environment, leading to discomfort or injury.
• 🧠 Psychosocial hazards involve workplace behavior and social conditions, including harassment, bullying, and stress.
• 🎯 A risk is the probability that a hazard will affect someone or something, resulting in an impact or injury.
• 📊 Risk assessment evaluates the probability and severity of harm, allowing for prioritization and mitigation efforts.

Q & A

What is the main focus of the video discussed in the transcript?

The video focuses on the concepts of hazards and risks in occupational safety and health, specifically on how to analyze these concepts to create a safe, secure, and healthy work environment.

What is the key difference between a hazard and a risk as described in the video?

A hazard is a potential source of harm, while a risk refers to the probability or chance that the hazard will cause harm when interacting with an object or person.

What are the five general categories of hazards mentioned in the video?

The five general categories of hazards are physical, chemical, biological, ergonomic, and psychosocial hazards.

Can you give an example of a physical hazard in the workplace?

An example of a physical hazard is exposure to excessive noise, high pressure, electricity, vibrations, or radiation in the workplace.

How are chemical hazards defined and what kind of harm can they cause?

Chemical hazards originate from solid, liquid, or gaseous chemicals that can irritate or injure the body, cause fires or explosions, and pose both health and safety risks.

What is an ergonomic hazard and how does it affect workers?

Ergonomic hazards arise when the design of a workspace does not align with human capabilities, leading to issues such as improper posture, repetitive movements, or poorly adjusted equipment, causing discomfort and long-term health problems.

What does the video say about psychosocial hazards, and how can they impact employees?

Psychosocial hazards are related to workplace behavior or social interactions that can affect both physical and psychological well-being. Examples include harassment, bullying, or stress from the work environment.

Why is it important to understand the probability of hazards turning into risks?

Understanding the probability helps in evaluating how likely it is that a hazard will impact a worker or object. This enables better risk management and prevention by focusing on high-probability hazards.

What is an example given in the video to explain how risk is assessed in a workplace scenario?

One example given is a water puddle in the workplace. If the puddle is near a frequently used entrance, the risk of someone slipping and getting injured is higher than if the puddle is in a less-traveled area. This illustrates how location and frequency of exposure affect risk assessment.

What is the role of an occupational health and safety specialist in managing hazards and risks?

An occupational health and safety specialist is responsible for identifying potential hazards, assessing associated risks, and implementing measures to minimize or eliminate the likelihood of harm to workers and the work environment.
