1.1 Safety on Raised Platforms

• Meaning of a raised platform as any surface used to work above the ground
• Types used to perform tasks: ladder, scaffold, raised platform, rooftop, farm tree, staircase
• School types to identify on a walk: trestle, steps, stand, mobile raised platform, work bench, ramp
• Risks: fall, slip, electric line and overload
• Safety: 1-out-4-up ladder angle, inspect, three points of contact, PPE, adult and trained for roofs
• Kenyan tasks: painting a school wall, picking mangoes, mabati roof work by trained adults

• identify types of raised platforms used in performing tasks
• describe risks associated with working on raised platforms
• observe safety when working on raised platforms
• appreciate the need for observing safety while working on raised platforms

1. Types of raised platforms
   40 min · 1 practice tasks · quiz
   A raised platform is any surface used to work above the ground. Grade 9 names six types used to perform tasks, then walks the school to identify more.
2. Ladders: one out, four up
   40 min · 1 practice tasks · quiz
   A leaning ladder is set 1 out, 4 up. Grade 9 measures the angle on the ground. Learners do not climb. A footer stays at the feet.
3. Scaffolds, trestles and mobile platforms
   40 min · 1 practice tasks · quiz
   A scaffold needs rails, ties and a load limit. Trestles and step stands stay short and locked. Mobile towers move empty with wheels locked to work.
4. Rooftops, farm trees and staircases
   40 min · 1 practice tasks · quiz
   Mabati roofs and tall farm trees are adult and trained work. Grade 9 stays on the ground. Stairs are a raised platform everyone uses, with a handrail.
5. Risks: fall, slip, line and overload
   40 min · 1 practice tasks · quiz
   Four risks to describe on raised platforms: fall, slip, electric line and overload. Learners search and match each risk to a Kenyan place.
6. PPE and ways to minimise risks
   40 min · 1 practice tasks · quiz
   Observe safety with helmet, closed shoes and a harness only when trained. Inspect, set 1-out-4-up, three points of contact, and stop for lines or overload.
7. Role-play: painting a school wall
   40 min · 1 practice tasks · quiz
   Rehearse painting a school wall with 1-out-4-up, a footer, tins on the ground and a clear fall zone. Learners do not climb. Love means caring for the person below.
8. Why height safety matters
   40 min · 1 practice tasks · quiz
   Appreciate safety on raised platforms: painters, mango pickers and mabati roofers go home when rules are kept. Locality visit is from the ground. Height is not a game.
