Understanding Hazards in the Workplace

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.
