EWP Environmental and Weather Conditions 2

Question 1

What instrument is used on or near an EWP worksite to accurately measure wind speed?

Accepted Answer

Anemometer

Answer

Barometer

Answer

Hygrometer

Answer

Thermometer

Question 2

Under Australian WHS guidelines, who shares responsibility for monitoring weather conditions during EWP operations?

Accepted Answer

Both the operator and the PCBU/supervisor share responsibility

Answer

Only the designated site safety officer is responsible for weather monitoring

Answer

The equipment hire company must monitor weather conditions remotely

Answer

Weather monitoring is the sole responsibility of the WorkSafe regulator

Question 3

When should an EWP operator consult the manufacturer's manual regarding weather operating limitations?

Accepted Answer

Before every operation, as weather limits vary between different EWP models

Answer

Only when adverse weather is already actively affecting site conditions

Answer

Once a year during the scheduled annual safety refresher training program

Answer

Only when a replacement operator takes over the same machine mid-shift

Question 4

What should an EWP operator do when dark storm clouds are observed approaching the worksite?

Accepted Answer

Lower the EWP to ground level and move it to a sheltered location before the storm arrives

Answer

Complete the current task as quickly as possible before the storm reaches the site

Answer

Raise the EWP platform higher to maintain visibility above the incoming cloud

Answer

Continue working and wait only for an official site shutdown instruction to be given

Question 5

What is the primary reason wind speed is a critical factor when operating an EWP with a long elevated boom?

Accepted Answer

Wind creates a horizontal force on the boom and platform, increasing the tip-over risk

Answer

Wind only affects the operator's comfort and concentration, not the machine's stability

Answer

Wind exclusively increases fuel consumption of the EWP drive engine during operation

Answer

Wind speed concerns only apply to boom-type EWPs operating directly over water

Question 6

Why must EWP operators working near a coast or in open paddock areas be especially vigilant about wind conditions?

Accepted Answer

Wind speeds are typically higher and more variable in open and coastal environments

Answer

Salt air causes immediate corrosion of EWP structural components during operation

Answer

Coastal areas have no overhead hazard restrictions allowing higher EWP working heights

Answer

Open areas allow higher wind speed tolerances because there are fewer physical obstacles

Question 7

What weather-related information should an operator record in the EWP logbook or daily pre-start checklist?

Accepted Answer

Current weather conditions and any weather-related hazards identified prior to commencing work

Answer

Nothing — weather recording is not a standard part of EWP pre-start documentation

Answer

Only wind speed readings that exceed 50 km/h need to be formally recorded

Answer

Weather data is only required for inclusion in monthly site safety compliance reports
