A Blower Insulator is responsible for installing, maintaining, and repairing insulators on blowers. Insulators are designed to prevent the flow of electricity from the blower to the ground, ensuring the safety of the operator and others in the vicinity.

1. Installation

The Blower Insulator may be required to install new insulators on blowers or replace existing ones.

• Inspects the blower to determine the type and number of insulators required.
• Installs insulators according to manufacturer’s specifications and industry standards.

2. Maintenance

The Blower Insulator is responsible for maintaining insulators on blowers to ensure their proper function and prevent accidents.

• Conducts regular inspections of insulators for damage, wear, or deterioration.
• Cleans and repairs insulators as needed.

3. Repair

The Blower Insulator may be required to repair insulators that have been damaged or have failed.

• Assesses the extent of damage to the insulator.
• Repairs or replaces damaged insulators.

4. Safety

The Blower Insulator must follow all safety protocols and procedures when working on blowers.

• Wears appropriate personal protective equipment (PPE).
• Follows lockout/tagout procedures when working on electrical equipment.

Preparing for a job interview can help candidates increase their chances of success. Here are some helpful tips:
