Examine forklift hazards and risks, including overturning, overloading, collisions, battery charging risks, which contribute to about 400 injuries and ten fatalities annually, plus silent operation and training gaps.

Identify hazards in passenger lifts, including overrun, fire risk, and trapped passengers. Implement automatic braking, dual suspension ropes, emergency stop, and direct rescue line with clear emergency procedures.

Identify hazards of disc cutters and cut-off saws, including high speed discs, eye injury, and electric shock, and apply controls: guards, proper wheels, two-handed grip, proper PPE.

Secure and clamp workpieces, fix sanding attachments, train operators, and use proper PPE when using hand-held sanders with a two-handed grip, acknowledging hazards from noise, entanglement, dust, heat, and fire.

Identify hazards of cartridge and pneumatic nail guns, including flying debris, recoil, nails driven by heavy charge, fire and explosion risks near flammables, high noise, electric shock, and compressor hazards.

explains adjustable guards for machine tools, including immovable guards with fixed clearance, and emphasizes trained operators, jigs or push sticks, proper lighting, and maintenance to minimize access to dangerous parts.

Interlocking guards interrupt power when the guard is not closed, eliminating hazards before access. They allow safe operation and maintenance without dismantling safety devices, but require maintenance to stay failsafe.

Identify secondary hazards of portable electrical appliances, including abrasion, noise, vibration, tripping and entanglement, and high risks from poorly maintained equipment, mains work, and live cables.

Select electrical equipment that suits the task and environment, considering flammable or explosive atmospheres, damp conditions, extreme temperatures, dirty or corrosive processes, and vegetation or animals, with isolation and earthing.

Protect people, plant, and premises from electrical hazards using protective systems. Fuses interrupt overcurrent to prevent overheating and fire, but do not prevent electric shock; inspections verify size and rating.

Explain how double insulation uses two independent layers of insulation over live conductors to provide double protection, preventing exposed parts from making the outer surfaces live in portable appliances.

Activate the emergency plan and notify emergency services, isolate the faulty device, do not touch a shock victim, follow fire procedures, and wait for a competent person to confirm safety.

Overhead lines are uninsulated conductors on poles or towers carrying 230 to 400,000 V. Keep equipment away from live lines or de-energize and barrier work near lines, obtaining permits.

Identify overhead lines on site, contact power supply and local authority for safe distances, and inform contractors to consult service provider about line divergence and plan work before starting.

Study the fire safety portion of the Nebosh course, covering fire starts and chemistry, fire risk assessment, rapid fire growth, and environmental impact, after the health and safety management system.

Identify carcinogenic, mutagenic, and reproductive toxin substances and explain acute and chronic health effects, emphasizing strict health and safety rules to protect workers.

Develop a preventive strategy to identify and control health risks before exposure. Address skin contact with irritants, respiratory sensitizers, workstation design, awkward postures, repetitive movements, noise, vibration, and ionizing radiation.

Learn employers' duties under chemical regulations, including health risk assessment, exposure prevention, health surveillance, control measures maintenance, monitoring, records, and emergency plans, plus employee training.

Implement engineering controls by segregating people from processes using local exhaust ventilation to capture fumes. Inspect and maintain equipment, and apply dilution ventilation for low toxicity contaminants not for dust.

Use manufacturer datasheets for safe handling and emergency procedures. Load substances in suitable containers, segregate from incompatible materials, attach emergency info to vehicles, and train drivers with aid and PPE.

Identify blue, brown, and white asbestos forms and why colour alone cannot identify products. Learn that respirable asbestos dust damages lungs and that work must stop if asbestos is discovered.

Identify and manage asbestos in premises under duty holder responsibility, assess presence and condition, maintain records, and implement plans to keep worker exposure and air fibre levels within limits.

Implement comprehensive asbestos control through PPE, ventilation, area segregation, method statements and air monitoring procedures, decontamination units, strong supervision, and workforce induction.

Provide medical surveillance for asbestos exposure above the action level, with exam within two years and follow-ups every two years; stop work after accidental exposure, and ensure showers and washes.

Explore how noise transmits through air and structures to cause ear damage, detailing acute effects: temporary threshold shift, tinnitus, and acute acoustic trauma, with reversible and potential permanent outcomes.

Handheld vibrating machinery such as pneumatic drills, sanders, and grinders pose hand-arm vibration syndrome, with symptoms like tingling, numbness, and reduced grip, influenced by vibration frequency and exposure duration.
