G60 Industrial Safety Protocols and Risk Assessment 4

Question 1

A torch operator discovers that a combustible gas detector has an expired calibration date. What should the operator do?

Accepted Answer

Take the detector out of service until it is recalibrated

Answer

Use the detector anyway since readings are approximate

Answer

Recalibrate it manually using ambient air as the zero reference

Answer

Increase monitoring frequency to compensate for potential drift

Question 2

Under the hierarchy of hazard controls, which option ranks BELOW engineering controls but ABOVE PPE?

Accepted Answer

Administrative controls

Answer

Substitution

Answer

Elimination

Answer

Isolation

Question 3

Which atmospheric condition, if identified during a pre-work survey, would PROHIBIT the issuance of a hot work permit?

Accepted Answer

Flammable vapor concentration at or above 10% LEL

Answer

Relative humidity above 80%

Answer

Ambient temperature above 90°F (32°C)

Answer

Wind speed exceeding 10 mph indoors

Question 4

An incident investigation follows a 'near miss' during torch operations. What is the PRIMARY goal of such an investigation?

Accepted Answer

To identify root causes and implement corrective actions to prevent recurrence

Answer

To assign disciplinary action to responsible workers

Answer

To satisfy insurance documentation requirements

Answer

To calculate cost liability for the event

Question 5

What is 'residual risk' in the context of torch operation risk assessment?

Accepted Answer

The level of risk that remains after all controls have been applied

Answer

The financial cost of property damage after an incident

Answer

The risk attributed solely to operator error

Answer

The probability of equipment failure per year

Question 6

When must a new hot work permit be issued for torch operations that extend beyond the original permit's time limit?

Accepted Answer

Before any additional work begins beyond the permitted time period

Answer

Never — the original permit covers the entire project scope

Answer

Only if a new ignition source is introduced to the area

Answer

At the end of each calendar month

Question 7

Which of the following is an example of an administrative control for torch operations near combustible materials?

Accepted Answer

Scheduling hot work for hours when the area is unoccupied

Answer

Installing a fire-resistant blanket barrier

Answer

Replacing flammable materials with non-combustible alternatives

Answer

Using a HEPA-filtered respirator
