8.2 Working at height

The first approach in the working at height hierarchy is to:

• 1 Use a harness
• 2 Use a safety net
• 3 Rely on training
• 4 Avoid working at height

An example of preventing a fall is:

• 1 An airbag
• 2 Warning signs only
• 3 A scaffold with guardrails
• 4 A safety net near the ground

Which minimises the consequences of a fall?

• 1 Safety nets
• 2 Scaffold boards
• 3 Ladders
• 4 Warning tapes

Which of these increases the risk of a fall from height?

• 1 A guarded platform
• 2 A short ladder in good condition
• 3 A solid floor
• 4 A fragile roof

Working at height should first be:

• 1 Avoided where possible
• 2 Left without supervision
• 3 Done with harnesses only
• 4 Planned as a routine

An example of avoiding working at height is:

• 1 Using an extendable tool from the ground
• 2 Using an airbag
• 3 Using a net
• 4 Using a harness

A mobile elevating work platform (MEWP) is an example of equipment that:

• 1 Prevents a fall when used properly
• 2 Is not useful
• 3 Minimises a fall only
• 4 Avoids height completely

Which of these minimises the distance of a fall?

• 1 A safety net close to the working level
• 2 A solid roof
• 3 A ground tool
• 4 A guardrail

Work restraint systems:

• 1 Catch a falling worker
• 2 Remove the need for training
• 3 Stop a worker reaching a fall edge
• 4 Increase the fall distance

A personal fall arrest system:

• 1 Prevents any fall
• 2 Replaces a net
• 3 Limits the consequences of a fall
• 4 Needs no training

Which is a main precaution for work at height?

• 1 No rescue plan
• 2 Planning and supervision
• 3 Using damaged ladders
• 4 Working in storms

The weather is a risk because:

• 1 It lowers insurance
• 2 It improves access
• 3 It is always dry
• 4 Wind and rain can make surfaces slippery and unstable

Falling materials are controlled by:

• 1 Safe stacking and storage
• 2 Leaving them at the edge
• 3 Throwing them from height
• 4 Using fragile tools

For ladders, a general precaution is:

• 1 Using them on slippery ground
• 2 Using them damaged
• 3 Correct selection, inspection and stability
• 4 Using them without training

An existing safe workplace such as a solid roof with guardrails is an example of:

• 1 Preventing a fall
• 2 Minimising a fall
• 3 Avoiding height
• 4 Ignoring the risk
