Pioneer Hygiene Products Interview Questions and Answers

Oil & gas is highly inflammable due to its low flash point and high volatility.

• Oil & gas have low flash points, which means they can ignite at relatively low temperatures.

• Oil & gas are highly volatile, meaning they evaporate quickly and form flammable vapors.

• The presence of hydrocarbons in oil & gas makes them highly combustible.

• Oil & gas can easily mix with air to form explosive mixtures.

• The high energy content in oil...read more

Low pressure and low voltage are used in petrochemical plants for safety and efficiency reasons.

• Low pressure is used to prevent leaks and accidents in the handling of volatile substances like oil and gas.

• Low voltage current is used to minimize the risk of electrical hazards and ensure worker safety.

• Low pressure and low voltage systems are more energy-efficient and cost-effective in petrochemical operations.

• Examples of ...read more

A relay is an electrically operated switch that opens or closes circuits electronically.

• Relays are used to control high voltage circuits with low voltage signals.

• They are commonly used in industrial automation, automotive applications, and household appliances.

• Relays can be either electromechanical or solid-state.

• Examples of relays include power relays, time-delay relays, and latching relays.

The current is the flow of electric charge in a circuit.

• Current is measured in amperes (A).

• It is caused by the movement of electrons or other charged particles.

• Current can be either direct current (DC) or alternating current (AC).

• DC flows in one direction, while AC periodically reverses its direction.

• Examples of current include the flow of electricity in a light bulb or the charging of a phone.
