ECT2

What is the most likely hazard to happen if you work in an electrical/electronics environment?

• Electrical hazard.

• Mechanical hazard

• Machinery hazard

• Chemical/biological hazard

Identify and recognize the risk and their level in the workplace.

• "Low, medium and high"

• "Minor, moderate and major"

• "Low Risk, basic and moderate"

• "No risk, high risk and extremely riskly"

"The use of a less hazardous or lower risk material, equipment or process is identified as"

• Elimination

• Substitution

• Engineering control

• Administrative control

The record of the assessment for incident should be created and keep for at least

• 6 months

• One year

• Two years

• Three years

Current can flow in a/an

• A. Insulator
• B. Conductor
• C. Both insulator and conductor
• D. Semi-conductive materials only

Alternating current (AC) periodically reverses between

• Positive and neutral

• Positive and positive alternation

• Negative and negative alternation

• Positive alternation and negative alternation

Amplitude and frequency refers to the

• Analog signals and digital signals respectively

• Digital signals and analog signals respectively

• Strength of a signal and number of cycles respectively

• Number of cycles and strength of a signal respectively

When a signal is repesentad by either 1 or 0 it is termed as

• Digital signal

• Analog signal

• Direct current signal

• Alternating current signal

"A function for cutting off an electrical installation, a circuit, or an item of equipment from every source of electrical energy is called"

• Isolation
