A. Sub‑strands explained (brief)

  • Safety in and outside the workshop: Rules and behaviours to avoid hazards—for example, PPE, no running, safe transport of tools and hot work outside the workshop.
  • General rules & OSHA (Kenya): Employer and worker responsibilities, training, safe systems of work, signage, record keeping and reporting incidents.
  • Causes of accidents: Slips, trips, incorrect machine use, lack of PPE, poor housekeeping, unsafe electrical connections, bad lighting and rushing tasks.
  • First aid: Immediate care for cuts, burns, fractures, electric shock and eye injuries until medical help arrives.
  • Workshop layout: Zones for cutting, welding, storage, finishing, PPE station, fire equipment and first aid.
  • Importance of safety: Avoid injuries, protect lives, reduce costs, keep machines running and meet legal requirements.

B. Safety inside and outside the metal workshop

Inside the workshop:

  • Always wear PPE: safety goggles, gloves, apron, ear protection and steel‑toe shoes.
  • Know the location of fire extinguishers, exits, first aid kit and emergency shutoffs.
  • Use machines only after instruction and when guards are in place. Switch off and isolate before maintenance.
  • Keep work area tidy; remove swarf and oil immediately to avoid slips.

Outside the workshop:

  • Transport hot or sharp items in boxes or with tool carriers; warn people nearby.
  • Dispose of metal waste in proper bins; do not leave sharp scraps on paths.
  • When working at client sites or outdoors, check for overhead hazards, electricity lines and stable ground.

C. General workshop rules & OSHA (Kenya) — key points

  • Employer duties: Provide safe workplace, PPE, training and first aid; ensure machines are safe and maintained.
  • Worker duties: Follow instructions, wear PPE, report hazards, and not operate machinery without permission/training.
  • Safe systems: Risk assessments, signage, emergency exits, clear walkways, and permit-to-work for hot work (welding/cutting).
  • Electrical safety: All fixed wiring and portable tools must be safe and earthed; no overloaded sockets.
  • Incident reporting: All accidents and near-misses must be recorded and reported to the school/workshop supervisor.
  • Training: Regular safety induction and refresher training for all learners and staff.

(These points reflect the principles of the Occupational Safety and Health Act, 2007 — Kenya.)

D. Possible causes of accidents in a metal workshop

  • Poor housekeeping (swarf, oil, clutter) → slips/trips.
  • Missing machine guards or using machines without guards → cuts, entanglement.
  • Improper PPE or no PPE → eye/hand/hearing injuries.
  • Electrical faults, exposed wires or wet floors → shocks.
  • Poor training or rushing → wrong tool use or incorrect settings.
  • Sparks from welding or cutting near flammable materials → fires/explosions.
  • Poor lighting or ventilation → mistakes, inhalation hazards.

E. First aid procedures (basic & immediate)

Important: For serious injuries call emergency services and a trained first aider. In Kenya use local emergency number (e.g., 999/112) or school emergency plan.

  • Bleeding (cuts):
    • Apply direct pressure with clean cloth; raise the limb if possible.
    • Do not remove embedded objects — apply padding around and seek help.
    • When bleeding slows, clean with clean water and cover with a sterile dressing; seek medical help if heavy bleeding.
  • Burns (hot metal/sparks):
    • Cool the burn with running cool (not icy) water for 10–20 minutes.
    • Remove jewelry or tight clothing near the burn unless stuck to the skin.
    • Cover with a sterile, non‑adhesive dressing; do not apply creams or ointments in serious burns — get medical care.
  • Eye injuries (metal particles):
    • Do not rub the eye. If particle is visible and not embedded, try flushing with clean water or saline from the inner corner outward.
    • If particle is embedded or pain persists, cover both eyes loosely and seek urgent medical help.
  • Fractures/suspected broken bones:
    • Immobilize the limb (splint) in the position found; do not try to realign bones.
    • Apply ice packs to reduce swelling (wrap ice in cloth).
    • Arrange transport to hospital and keep casualty warm and calm.
  • Electric shock:
    • Do not touch the casualty if they are still in contact with the electrical source.
    • Isolate power (switch off at source) or use non-conducting object (wood/rope) to separate casualty from source.
    • If breathing stops, begin CPR and call emergency services immediately.

F. Components of a metal workshop layout

A safe workshop is divided into clear zones. Typical components:

  • Entrance / Reception
  • PPE station / lockers
  • Workbenches / fabrication benches
  • Cutting and machining area (lathe, drill press, cutters)
  • Welding and hot work bay (with welding screens)
  • Grinding/finishing area (with local exhaust ventilation)
  • Material storage (raw and finished) — labelled and off the floor
  • Flammable materials store (separate, ventilated)
  • First aid box / sick bay and eye wash station
  • Fire extinguishers and emergency exits clearly marked

G. Importance of safety in the metal workshop

  • Protects students and staff from injury and long‑term harm.
  • Ensures continuous learning — fewer interruptions from accidents.
  • Reduces costs related to medical care and equipment damage.
  • Complies with legal and school safety requirements (OSHA, school policy).
  • Builds professional habits that learners will take into industry.

Suggested learning experiences (Kenyan context, age 15)

  • Safety induction: Teacher demonstrates PPE use and machine guards; learners practice putting on PPE.
  • Workshop safety inspection: In small groups, use a checklist to find 10 hazards in the school workshop and suggest fixes.
  • First aid role‑play: Simulate cuts, burns and eye injuries; practise safe first aid steps and calling for help.
  • Create safety posters: Groups design posters in English or Kiswahili for PPE, fire procedure or machine safety.
  • Mock emergency drill: Practice evacuation route and meeting point; check fire extinguishers and first aid kit.
  • Invite a local tradesperson or OSHA representative to speak on workplace safety and apprenticeships.
  • Assessment: Short quiz, practical demonstration of safe machine setup and a group presentation on the inspection findings.

Materials and teacher notes

  • Materials: PPE sets for demonstrations, first aid kit, fire extinguisher, safety checklist templates, basic SVG/printed floorplan.
  • Teacher notes: Supervise all practicals closely; never allow students to use machines without consent and prior training. Keep emergency contacts and parental information available.
Reminder: This guide is for classroom learning. For serious injuries, get professional medical help immediately. Follow your school’s safety policy and the Occupational Safety and Health Act (Kenya).
