GRADE 9 Pre-technical FOUNDATIONS OF PRE-TECHNICAL STUDIES – SAFETY ON RAISED PLATFORMS Notes
FOUNDATIONS OF PRE-TECHNICAL STUDIES
Subtopic: SAFETY ON RAISED PLATFORMS
Target age: 14 (Kenyan schools). These notes explain safe behaviour when working on raised platforms such as scaffolds, stages, ladders, mezzanines and roofs. Always follow your teacher’s or supervisor’s instructions and Kenyan school safety rules.
What is a raised platform?
Any place that is higher than ground level where people work or move — for example, ladders, scaffolding, raised stages, roofs and platform edges.
Common hazards
- Falls from height (most serious).
- Objects falling from the platform and hitting people below.
- Slips and trips because of poor footwear or clutter.
- Unstable or damaged ladders/scaffolds.
- Working near edges without guardrails.
Basic safety rules (Easy to remember)
Before you start:
- Get permission from your teacher/supervisor.
- Inspect the platform or ladder for damage.
- Keep the area below clear of people and belongings.
- Wear closed shoes with good grip (no sandals).
- Use tools in a belt or container so hands are free when climbing.
While on the platform:
- Always face the ladder when climbing (🪜).
- Keep at least one hand free to hold on while climbing.
- Do not overload — only as many people/equipment as allowed.
- Do not have loose items or push someone else on a platform.
- Never jump off a raised platform — climb down carefully.
Personal Protective Equipment (PPE)
- Non-slip closed shoes (safety shoes if available).
- Hard hat where objects may fall from above.
- Gloves for good grip when handling tools or materials.
- High-visibility vest if working around vehicles or heavy equipment.
- Harness and fall-arrest system if working at significant heights (follow teacher/supervisor instructions).
Using a ladder safely — quick steps
- Place ladder on firm, level ground. Top and base must be secure.
- Set ladder at the correct angle — about 1 out for every 4 up (bottom 1m away for 4m height).
- Climb slowly, facing the ladder, with three points of contact (two feet + one hand or two hands + one foot).
- Do not stand on the top two rungs of a stepladder.
- Do not overreach; move the ladder instead.
Scaffolding and elevated work platforms
- Only use scaffolds erected by a trained person.
- Ensure guardrails and toe boards are fitted to stop falls and falling objects.
- Check planks are secure and free from cracks.
- Never remove guardrails for convenience.
- Do not push tools or materials off the platform — lower them safely using ropes or a controlled method.
Quick safety checklist (do this before using a raised platform)
- Permission and supervision present? ✅
- Platform/ladder inspected and in good condition? ✅
- Guardrails and toe boards fitted? ✅
- Proper footwear and PPE worn? ✅
- Tools secured and area below cleared? ✅
If there is an accident or fall
- Stay calm. Do not move an injured person unless they are in immediate danger.
- Call for the teacher, supervisor or first aider immediately.
- For serious injury call emergency services — in Kenya call 999 or 112 and inform the school office.
- Provide first aid if trained. Stop bleeding with pressure and keep the person warm.
- Report the incident to the teacher and write a short report of what happened.
School & Kenyan context — notes for students
- Follow your school’s safety rules and the teacher’s instructions at all times.
- Kenyan schools must keep students safe at work practice. Report unsafe conditions to a teacher or the school safety officer.
- Never use equipment you have not been trained to use.
Short review quiz (answer with your teacher)
- Why should you always have three points of contact on a ladder?
- Name two pieces of PPE needed when working on a roof.
- What should you do first if you see a broken scaffold at school?
Remember: Safety is everyone’s job. Always think before you climb, wear the right shoes, and ask for help when unsure. ⚠️✅
