Confined space is an area that is not designed for continuous occupancy, has limited entry and exit points, and may have hazardous conditions.

• Confined spaces are typically small and enclosed, making it difficult to enter and exit.

• These spaces may have poor ventilation, limited lighting, or contain hazardous substances.

• Examples of confined spaces include storage tanks, silos, tunnels, and sewers.

Oxygen level in confined spaces should be monitored to ensure safety of workers.

• Oxygen levels in confined spaces should be maintained between 19.5% and 23.5%.

• Low oxygen levels can lead to dizziness, confusion, and even loss of consciousness.

• High oxygen levels can increase the risk of fire and explosion.

• Monitoring equipment such as oxygen meters should be used to regularly check oxygen levels in confined spaces.

DOL starter stands for Direct-On-Line starter, used to start motors by directly connecting them to the power supply.

• DOL starter is the simplest and most common type of motor starter.

• It directly connects the motor to the power supply without any intermediate starting method.

• It provides full voltage to the motor during starting, which can cause high inrush current.

• DOL starters are suitable for small to medium-sized motor...read more

APFC PANEL stands for Automatic Power Factor Correction Panel, used to maintain power factor in electrical systems.

• APFC PANEL automatically monitors and corrects the power factor of electrical systems.

• It helps in reducing electricity bills by maintaining a high power factor.

• APFC PANELs are commonly used in industries and commercial buildings.

• They consist of capacitors that are switched on and off based on the load requ...read more
