Abrasive Wheels Training Certificate PPE and Risk Assessment 2

Question 1

What type of hearing protection may be required during prolonged abrasive wheel operations?

Accepted Answer

Ear defenders or ear plugs conforming to BS EN 352 when noise exceeds 80 dB(A)

Answer

No hearing protection is needed as grinding is quiet

Answer

Cotton wool in the ears is sufficient

Answer

Hearing protection is only needed above 100 dB(A)

Question 2

Which of the following is a key control measure to reduce dust exposure during dry grinding operations?

Accepted Answer

Local exhaust ventilation (LEV) fitted at the point of dust generation

Answer

Opening a window

Answer

Sweeping the floor regularly

Answer

Working faster to reduce exposure time

Question 3

What must a suitable and sufficient risk assessment for abrasive wheel use include?

Accepted Answer

Identification of hazards, who might be harmed, evaluation of risks, control measures, and review date

Answer

Only the names of employees who will use the equipment

Answer

Only the manufacturer's safety data sheet

Answer

A photograph of the abrasive wheel

Question 4

When is respiratory protective equipment (RPE) required during abrasive wheel operations?

Accepted Answer

When engineering controls such as LEV cannot adequately control dust exposure below workplace exposure limits

Answer

Never, as dust from grinding is not harmful

Answer

Only when grinding lead-based materials

Answer

RPE is only recommended, never required

Question 5

Under the Hand Arm Vibration Regulations 2005, what is the daily exposure action value for hand-arm vibration?

Accepted Answer

2.5 m/s²

Answer

1.0 m/s²

Answer

5.0 m/s²

Answer

10.0 m/s²

Question 6

What should be done if a risk assessment identifies that an abrasive wheel operation presents a fire risk from sparks?

Accepted Answer

Remove combustible materials from the area, provide appropriate fire extinguishers, and use spark guards/screens

Answer

Ignore it as sparks are a normal part of grinding
