Question

Accepted Answer

The Safety Officer/Safety Engineer interview questions include construction site experience, difference between MCB & RCCB, and safety measures for electric shock.

Yes, I have seen construction sites and have experience in ensuring safety protocols.
MCB (Miniature Circuit Breaker) and RCCB (Residual Current Circuit Breaker) are both electrical protection devices, but with different functions.
MCB is designed to protect against overcurrent and short circuits, while RCCB is used to detect and protect against earth leakage currents.
The best choice depends on the specific application and electrical system requirements.
If I insert my fingers in the electric switch box, I would take the following safety measures:
- First, I would ensure the power supply is turned off before attempting any intervention.
- I would wear appropriate personal protective equipment (PPE) such as insulated gloves.
- I would use insulated tools to avoid direct contact with live parts.
- I would follow lockout/tagout procedures to isolate the electrical circuit.
- I would also ensure proper grounding and bonding of the switch box to minimize the risk of electric shock.
These measures aim to protect against electric shock and ensure the safety of personnel.

A hazard is something that has the potential to cause harm while risk is the likelihood of harm taking place, based on exposure to that hazard.

What is the formula to calculate risk?

How to calculate risk

AR (absolute risk) = the number of events (good or bad) in treated or control groups, divided by the number of people in that group.
ARC = the AR of events in the control group.
ART = the AR of events in the treatment group.
ARR (absolute risk reduction) = ARC – ART.
RR (relative risk) = ART / ARC.

Risk terms

AR (absolute risk) = the number of events (good or bad) in treated or control groups, divided by the number of people in that group
ARC = the AR of events in the control group
ART = the AR of events in the treatment group
ARR (absolute risk reduction) = ARC – ART
RR (relative risk) = ART / ARC
RRR (relative risk reduction) = (ARC – ART) / ARC
RRR = 1 – RR
NNT (number needed to treat) = 1 / ARR

Examples

RR of 0.8 means an RRR of 20% (meaning a 20% reduction in the relative risk of the specified outcome in the treatment group compared with the control group).
RRR is usually constant across a range of absolute risks. But the ARR is higher and the NNT lower in people with higher absolute risks.
If a person's AR of stroke, estimated from his age and other risk factors, is 0.25 without treatment but falls to 0.20 with treatment, the ARR is 25% – 20% = 5%. The RRR is (25% – 20%) / 25% = 20%. The NNT is 1 / 0.05 = 20.

RCCB stands for Residual Current Circuit Breaker. ... It is the safest device to detect and trip against electrical leakage currents, thus ensure protection against electric shock caused by direct contacts. RCCB is generally used in series with an MCB which protects them from over current and short circuit current
