Step 1
Identify THREE parts that have been omitted from the structure that will negatively impact on the safety of workers.
Answer
The three omitted parts that negatively impact safety are:
-
Baseplate: This is essential for stability as it helps distribute the load and secure the scaffold to the ground.
-
Soleplate: Similar to the baseplate, it provides a flat surface for the structure and is crucial in preventing sinking into the ground.
-
Guardrails: These are vital for preventing falls by providing a safety barrier around the platform.
Step 2
Predict what could happen if the platform is used as shown in FIGURE 1.1.
Answer
If the platform is used as shown in FIGURE 1.1, several dangerous outcomes could occur:
- Workers may fall from the scaffold due to the lack of guardrails, leading to serious injuries or fatalities.
- Tools and materials could fall from the scaffold onto workers below, causing accidents and injuries.
- The scaffold may tip over if the vertical standards sink into the ground, risking collapse.
Step 3
Step 4
Explain why it is advisable to keep the height of the guard rails between 900 to 1 000 mm above the scaffold working platform.
Answer
Keeping the height of the guard rails between 900 to 1 000 mm is advisable to ensure:
- Worker safety: This height prevents workers from falling off the platform by acting as a physical barrier.
- Ease of access and movement: It allows workers to lean against the rails without feeling over-restricted while still providing adequate protection.
Step 5
Describe ONE precaution that must be adhered to when storing a ladder.
Answer
One important precaution is to store a ladder in a dry place after use. This prevents the ladder from becoming damaged by moisture, which can lead to rust or deterioration, ensuring its longevity and safety for future use.
Step 6
Describe ONE check that the operator needs to perform before the builder's hoist moves.
Answer
The operator must check that the gates are shut when the device is being used. This ensures that materials and workers remain securely within the hoist, preventing accidental spills or falls during movement.
Step 7
Explain why the fire-fighting measures must be stated in the material safety data sheet of hazardous chemical substances.
Answer
Fire-fighting measures are crucial in the material safety data sheet to provide:
- Immediate information on how to respond in case of a fire involving the substance.
- Guidance for emergency responders to ensure that they can effectively control any fire-related incidents, protecting both people and property.
