Fatal Risks and Controls Scan

1. Fatal Risks in High-Risk Industries

Common Fatal Risks:

1. Falls from Heights

• • Risk: Workers falling from ladders, scaffolds, elevated platforms, or open edges.

• • Fatalities: A significant cause of fatalities, especially in construction, mining, and maintenance work.

2. Vehicle and Mobile Equipment Accidents

• • Risk: Collisions involving trucks, cranes, excavators, bulldozers, or other heavy machinery.

• • Fatalities: Often result from rollovers, driver errors, inadequate signage, or insufficient communication in busy, congested areas.

3. Crushing and Striking by Objects

• • Risk: Workers being struck by falling objects, caught between machinery, or crushed by equipment.

• • Fatalities: These types of accidents can occur due to improper securing of loads, lack of barricades, or faulty machinery.

4. Explosions and Fires

• • Risk: Workers being exposed to explosions, flash fires, or other combustion-related hazards, especially in environments with flammable materials or gases (e.g., mining, oil & gas).

• • Fatalities: Often caused by gas leaks, improper handling of combustible materials, or electrical sparks.

5. Confined Space Incidents

• • Risk: Fatalities occur in confined spaces due to lack of oxygen, toxic atmosphere, or hazardous mechanical or electrical equipment.

1. • Fatalities: Workers may be overcome by gases, chemicals, or lack of ventilation in confined or enclosed spaces.

6. Electrocution

1. • Risk: Coming into contact with live electrical wires, faulty equipment, or unsafe electrical installations.

1. • Fatalities: Typically caused by workers working on electrical systems without proper isolation, protection, or training.

7. Cave-ins or Mine Collapses

1. • Risk: In mining operations, the collapse of tunnels or shafts, or a landslide in open-pit mining.

1. • Fatalities: Often result from inadequate ground support, poor ventilation, or seismic activity.

8. Asphyxiation and Toxic Exposure

1. • Risk: Inhalation of toxic gases, fumes, or dust particles (e.g., carbon monoxide, silicosis, asbestos).

1. • Fatalities: Often a result of inadequate ventilation, failure to wear respirators, or poor monitoring of air quality in confined spaces or enclosed areas.

9. Machinery and Equipment Malfunctions

1. • Risk: Accidents caused by machinery failure, malfunctioning safety features, or improper operation.

1. • Fatalities: Can happen when workers are caught in or between moving parts or when safety guards are bypassed.

10. Manual Handling and Lifting

1. • Risk: Fatalities caused by improper lifting, overexertion, or being struck by or crushed by loads.

1. • Fatalities: Workers can be injured or killed when lifting heavy loads manually without proper lifting techniques or equipment.

2. Controls for Fatal Risks

To reduce the likelihood of fatal incidents, it’s essential to implement control measures aligned with the Hierarchy of Controls, a system used to identify the most effective methods of eliminating or reducing risks.

A. Elimination and Substitution (Most Effective)

• Eliminate the hazard: Where possible, completely remove the risk from the work environment.

• • Example: If working at height is a risk, eliminate the need for elevated work by using equipment like cranes, hoists, or automated machinery.

• Substitute hazardous processes or materials: Replace hazardous chemicals or substances with safer alternatives.

• • Example: Substituting a more toxic chemical with a less toxic one in a chemical manufacturing process.

B. Engineering Controls

• Physical changes to the work environment: Modify equipment, machinery, or the workspace to reduce risks.

• • Example: Installing guardrails or fall arrest systems to prevent falls from heights.

• • Example: Lock-out/tag-out procedures and systems to prevent machinery from being accidentally energized during maintenance.

• • Example: Ventilation systems in confined spaces to ensure breathable air and reduce toxic exposures.

• • Example: Reinforcing mine tunnels with support structures to prevent cave-ins.

C. Administrative Controls

• Safe Work Procedures (SWPs): Develop and enforce clear work procedures that outline how tasks should be safely performed.

• • Example: Establishing standard operating procedures (SOPs) for machinery operation and maintenance.

• Permit-to-work systems: Require formal permits for high-risk activities (e.g., hot work, confined space entry).

• • Example: Issuing a hot work permit before allowing welding or cutting in areas where flammable materials are present.

• Signage and Warnings: Use visual warnings (signs, lights, barriers) to indicate hazardous areas.

• • Example: Warning signs for areas with risk of falling objects, high noise levels, or toxic gas exposure.

• Training and Supervision: Continuous safety training and regular supervision.

• • Example: Provide confined space entry training for all personnel working in or around such environments.

• • Example: Regular refresher courses on PPE usage, first-aid training, and emergency evacuation protocols.

D. Personal Protective Equipment (PPE)

• Provide PPE to minimize exposure to hazards.

• • Example: Workers must wear fall protection gear (harnesses, lanyards) when working at height.

• • Example: Workers handling chemicals should wear gloves, goggles, and respirators to protect against exposure.

• • Example: In noisy environments, workers should wear hearing protection to avoid permanent hearing damage.

• • Example: High-visibility clothing for workers operating in areas with moving vehicles or machinery.

E. Emergency Preparedness

• Develop and communicate emergency procedures tailored to fatal risks.

• • Example: In case of an explosion, establish evacuation routes, muster points, and first-aid procedures.

• • Example: For mining or confined space work, have a rescue team trained in emergency extraction and provide first-aid and medical evacuation plans.

• Regular Drills and Training: Conduct frequent drills for emergency situations like fires, medical emergencies, or equipment malfunctions.

• • Example: Fire drills, evacuation drills, and first-aid training for all site workers.

• • Example: Conduct mine rescue drills to practice response to underground collapses or gas leaks.

3. Fatal Risk Example and Control Measures:

Risk: Falls from Heights (e.g., scaffold collapse, falling from ladders or roofs)

• Control Measures:
  1. Elimination/Substitution: Use lifts, platforms, or aerial work platforms to eliminate the need for workers to perform tasks at height.
  2. Engineering Controls: Install guardrails, safety nets, or fall arrest systems. Secure ladders and scaffolds, ensuring they are stable and maintained.
  3. Administrative Controls: Establish safe work procedures for working at height, conduct hazard assessments before work begins.
  4. PPE: Provide personal fall arrest systems (harnesses and lanyards) and ensure their proper use.
  5. Training: Provide workers with fall prevention training and ensure they are aware of the risks of working at height.

Risk: Vehicle and Equipment Accidents

• Control Measures:
  1. Elimination/Substitution: Where possible, reduce or eliminate vehicle use by using automated equipment or aerial hoists.
  2. Engineering Controls: Install crash barriers, speed bumps, or warning signs to prevent vehicle collisions.
  3. Administrative Controls: Implement traffic management plans, designate walkways, and vehicle zones.
  4. PPE: Ensure workers wear high-visibility clothing when working near vehicles or moving machinery.
  5. Training: Ensure all vehicle operators and workers are trained in safe driving practices, pedestrian safety, and equipment handling.
