Study Notes
Definition of Hazard
- A hazard is anything that has the potential to cause harm.
Types of Hazards
- Physical Hazards: Include slippery floors, misused machinery, radiation, excessive noise, poor lighting, and fire.
- Chemical Hazards: Involve harmful substances like gases, dusts, fumes, vapors, and liquids.
- Ergonomic Hazards: Result from poorly designed equipment, risky workstation layouts, and repetitive movements.
- Psychological Hazards: Arise from shift work, workload pressures, harassment, discrimination, and constant noise.
- Biological Hazards: Include infections from bacteria, viruses, fungi, or parasites through various means such as cuts or insect bites.
Hazard Examples
- A moving lorry on a site represents a physical hazard as it poses a risk of running over a worker.
- Sodium hydroxide is a chemical hazard due to its corrosive nature.
- A damaged electrical code can lead to electric shock, highlighting a potential danger.
Characteristics of Hazards
- Some items are inherently hazardous, while others become so when misused.
- Accidents often result from negligence or disregarding hazardous situations.
Categories of Hazards
- Acute Hazards: Immediate and obvious risks, e.g., slippery floors.
- Chronic Hazards: Long-term impacts that may be less apparent, e.g., workplace bullying leading to stress.
Understanding Risk
- Risk is the likelihood of a hazard causing harm combined with the potential severity of that harm.
- Risks can be qualitatively categorized as high, medium, or low.
- Risk can be calculated using the formula: Risk = Likelihood x Consequences.
Types of Risks
- Personal Risk: Loss due to sickness, disability, or unemployment.
- Property Risk: Losses due to dangers, such as fire or theft.
- Liability Risk: Losses from negligence resulting in injury or property damage.
Basic Elements of a Health and Safety Program
- Management commitment and employee involvement are crucial.
- Worksite analysis and hazard prevention/control measures are necessary.
- Safety and health training must be implemented.
Importance of a Safety Plan
- A Safety Plan outlines processes for identifying hazards, preventing accidents, and responding to incidents.
- It may include method statements, job safety analyses, and project safety plans.
Occupational Safety and Health (OSH)
- OSH is a multidisciplinary field focused on ensuring safety, health, and welfare in workplace environments.
- It is essential for mitigating risks across various industries and protecting employees.
