Top 10 Questions for Puffer Tender Interview

1. Describe the purpose and function of a puffer tank?

A puffer tank is a device used in the shipbuilding and repair industry to create a temporary, enclosed, and inflatable environment within a compartment or space of a vessel. Its primary function is to provide a safe and controlled space for workers to perform tasks such as welding, painting, and cleaning in areas that are inaccessible or hazardous due to the presence of confined spaces, toxic fumes, or other safety concerns.

2. Explain the process of preparing a puffer tank for use, including safety precautions and equipment required?

Safety Precautions:

• Ensure proper ventilation to prevent the accumulation of toxic fumes.
• Wear appropriate protective gear, including respirators, gloves, and eye protection.
• Inspect the puffer tank for any damage or leaks before use.
• Follow established safety protocols and guidelines.

Equipment Required:

• Puffer tank and blower
• Air supply and hoses
• Clips or clamps to secure the tank in place
• Lights and electrical equipment for illumination
• Tools and materials required for the specific task

3. How do you maintain and troubleshoot a puffer tank during operations?

During operations, it is crucial to maintain the integrity and functionality of the puffer tank. Regular maintenance includes checking for leaks, ensuring proper air pressure, and inspecting the blower for proper operation. Troubleshooting involves identifying potential issues, such as air leaks, blower malfunctions, or power supply problems. Prompt repairs or adjustments should be made to maintain a safe and effective working environment.

4. Describe the different types of materials used for puffer tank construction and their respective advantages and disadvantages?

Puffer tanks are typically constructed using various materials, each with its unique advantages and disadvantages. Common materials include:

• PVC (Polyvinyl chloride): Lightweight, flexible, and durable, PVC is commonly used for smaller tanks due to its ease of handling and installation.
• PU (Polyurethane): Known for its high strength, abrasion resistance, and chemical resistance, PU is suitable for heavy-duty applications and harsh environments.
• Rubber: Provides excellent air retention and flexibility, making it suitable for complex shapes and confined spaces. However, it can be more expensive than other materials.

5. Explain the importance of proper ventilation and air supply when working with a puffer tank?

Adequate ventilation and air supply are critical for the safety of workers using a puffer tank. The purpose of ventilation is to prevent the accumulation of toxic fumes and ensure a fresh air supply within the enclosed space. Proper air supply maintains the required pressure inside the tank, creating a positive pressure environment that prevents outside contaminants from entering the work area. This helps protect workers from exposure to hazardous substances and ensures a safe and healthy working environment.

6. Describe the emergency procedures to follow in case of a puffer tank failure or malfunction?

In the event of a puffer tank failure or malfunction, it is crucial to follow established emergency procedures to ensure the safety of workers and minimize potential hazards. These procedures may include:

• Immediately evacuate all workers from the affected area.
• Identify the source of the failure or malfunction and take steps to isolate it.
• Contact the supervisor or designated emergency personnel for assistance.
• Ventilate the affected area to remove any accumulated fumes or gases.
• Do not re-enter the area until it has been deemed safe by authorized personnel.

7. What are the key safety regulations and industry standards applicable to the use of puffer tanks?

The use of puffer tanks must adhere to various safety regulations and industry standards to ensure the safety of workers and compliance with legal requirements. These regulations may include:

• Occupational Safety and Health Administration (OSHA) regulations
• American Welding Society (AWS) standards
• National Fire Protection Association (NFPA) codes
• Specific regulations or guidelines set by the shipyard or employer

Compliance with these regulations is crucial to minimize risks, prevent accidents, and ensure a safe work environment.

8. What are the common challenges faced while working with puffer tanks and how do you overcome them?

Working with puffer tanks can present various challenges, including:

• Confined spaces: Working in a confined space within the tank requires proper ventilation and safety measures.
• Air leaks: Maintaining a consistent air supply and pressure is crucial to prevent collapse or deformation of the tank.
• Toxic fumes: Welding, painting, or other activities within the tank can generate hazardous fumes, necessitating proper ventilation and respiratory protection.
• Electrical hazards: Lighting and equipment used within the tank must be properly grounded and protected against moisture.

To overcome these challenges, it is important to follow safety protocols, use proper equipment, maintain regular maintenance, and have a contingency plan in place for emergencies.

9. How do you coordinate with other team members when working on a project involving a puffer tank?

Effective coordination is vital when working with puffer tanks on a project. Communication and teamwork are essential to ensure a safe and efficient work environment. Responsibilities may include:

• Communicating safety protocols and procedures to all involved team members.
• Assigning roles and responsibilities for tank setup, maintenance, and monitoring.
• Coordinating with ventilation and electrical personnel to ensure a safe and well-ventilated work area.
• Maintaining regular communication to address any issues or concerns that arise during the project.

10. Describe a specific project where you successfully utilized a puffer tank and the key challenges you encountered?

In a recent shipyard project, I was responsible for using a puffer tank to create a controlled environment for welding repairs on a large cargo vessel. The key challenges included:

• Confined space: The work area within the tank was narrow and required careful planning for ventilation and worker access.
• Toxic fumes: Welding created significant fumes, necessitating the use of respirators and a constant supply of fresh air.
• Air leaks: Maintaining a consistent air pressure inside the tank was crucial to prevent its collapse during welding.

To overcome these challenges, I worked closely with the ventilation team to ensure proper air circulation and monitored the air pressure regularly. I also implemented a safety protocol for entering and exiting the tank to minimize the risk of exposure to fumes. The project was successfully completed within the specified timeframe, maintaining the highest safety standards.
