electrostatic sensitive device
This sounds like a question from a sheet I did or actually had for HW the answer is they eliminated the heat sensitive components
Thermal analysis are used to prevent the electronics circuit being damaged, such as heat sinks are used to absorb the heat which is created by the components to protect the sensitive components
GALVANOMETER detects very small currents in terms of milli amperes so it is said to be called as sensitive
they do not have any electrical property that is polarity sensitive
Transistor failure can occur due to a variety of reason. The following are some of them. Age Aging of transistor due to temperature variations inside the components due to carrying current can cause failure. The electrical properties of the materials inside can drift due to age. External Causes External causes such as spikes in the power supply, heat, mechanical damage can also result in transistor failures. Hence, all transistors should be adequately protected against overvoltage. Poor Circuit design. Improperly chosen components and wrong circuit design can also result in transistor failure. Hence, all components in the circuit should be properly rated with sufficient allowance for overloading and temperature rise. The failure of one component can lead to cascade failures of other components. Overheating Overheating is the most common cause of transistor failure. Hence, it is important that transistors be provided with cooling mechanism. Devices which contain temperature-sensitive electronic components should be kept in air conditioned environments. Electrostatic Discharge Electrostatic discharge can also damage transistors. Hence proper precautions against Electrostatic Discharge Should be taken.

1500v From ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1: "When people are charged with static electricity, they can release stored energy to conductive objects such as doorknobs and electronic circuits. This transfer of energy is called an electrostatic discharge. Sometimes the electrostatic discharge causes visible sparks, but more often, it is both unseen and unfelt. Electrostatic discharges can damage ESD sensitive components used in modern electronics. Static electricity is a natural phenomenon that occurs in all climates and at all levels of relative humidity year round. Most people cannot feel an electrostatic discharge unless the static voltage is greater than 2000 volts. However, some electronic circuitry can be damaged by ESD that is less than 2000 volts. The damage can be done without people having any sensation of the ESD event. When a wrist strap is worn properly and connected to ground, the person wearing it will stay near ground potential."

By keeping it inside in a hollow conducting sphere. This process is known as electrostatic shielding.

electrostatic shielding is the method of protecting a certain region of space or any sensitive instrument from the influence of the external field produced by an electric charge

Anti-static bubble bags are an essential component of an ESD (electrostatic discharge) protection program. These bags are designed to protect electronic components and other sensitive items from damage caused by static electricity. The bags are made from specialized materials that are static dissipative, which means that they can prevent the buildup of static electricity and promote grounding.

Human body have electrostaticelectricity and MOSFET are made with Field Effect Transistor, a kind of transistor very sensitive to electricity including electrostatic. Specifically, MOSFETs have a very thin gate oxide layer, which insulates the gate from the source and drain. Exceeding the gate voltage limit can "punch a hole" in the oxide layer, so to speak, causing permanent damage to the device. The gate oxide is much more sensitive to electrostatic discharge than the source/drain junctions.
