This slide was all about hazard and risk identification

1. LESSON 2: HAZARDS & RISKS IDENTIFICATION & CONTROL

2. At the end of this lesson the students must be able to; 1. Define hazard and risks. 2. Identify safety regulations in the workplace 3. Differentiate the different types and methods of hazards  

3. Give some “ what if” situations that can cause any accidents in workplace.

4. 1. What is the difference between hazard & risk? 2. Why do you think it is necessary to identify hazards & risks in workplace?

5. HAZARD a source or situation with a potential to cause harm in terms of injury, ill health, damage to property, damage to the environment or a combination of these. is the likelihood of a person being injured or receiving an adverse health effect due to a hazard. RISK

6. TYPES OF HAZARDS Physical - includes floors, stairs, work platforms, steps, ladders, fire, falling objects, slippery surfaces, manual handling (lifting, pushing, pulling), excessively loud and prolonged noise, vibration, heat and cold, radiation, poor lighting, ventilation, air quality

7. TYPES OF HAZARDS Mechanical and/or electrical - includes electricity, machinery, equipment, pressure vessels, dangerous goods, forklifts, cranes, hoists

8. TYPES OF HAZARDS Chemical – substances that can cause harm includes chemical substances such as acids or poisons and those that could lead to fire or explosion, cleaning agents, dusts and fumes from various processes such as welding

9. Four Possible Routes of Entry of Chemical Hazards 1. Inhalation-breathing 2. Ingestion- Eating 3. Absorption- Through the skin and eyes 4. Injection

10. TYPES OF HAZARDS Biological – hazards are caused by living organisms includes bacteria, viruses, molds, mildew, insects, vermin, animals that can cause adverse health impacts. These health impacts can range from skin and respiratory system irritation, to the transmission of infections.

11. TYPES OF HAZARDS Ergonomics – this hazard is a result of physical factors that can results in musculoskeletal injuries. For example: a poor workstation setup in an office, poor posture and manual handling.

12. TYPES OF HAZARDS Psychosocial environment – hazards that can have an adverse effect on an employee’s mental health or wellbeing includes workplace stressors arising from a variety of sources. For example: sexual harassment, stress & workplace violence

13. When considering the degree of risk that a hazard poses to the employee, the ff . factors can influence risk must be bear in mind The frequency of exposure The route of exposure How severe the injury or adverse health effect of exposure is

14. Methods for Identifying Hazards Review workers injury and illness records Staying informed on trends and developments in workplace health and safety Reviewing the potential impact of new work practices or equipment introduced into the workplace in line with legislative requirements Doing walk-through surveys, inspections or safety audits in the workplace.

15. Methods for Identifying Hazards considering OHS implications when analyzing work processes investigating workplace incidents and `near hits' reports getting feedback from employees Consulting with employees, health and safety representatives and OHS Committee members
