Handling hazardous liquids demands not only precision but also an unwavering commitment to safety. At D&R Packaging, we build hazardous liquid filling machines that meet industry safety standards while ensuring efficient operation. This guide covers key design considerations, compliance requirements, and how our solutions help maintain a safe production environment.
What are Hazardous Liquid Filling Machines?
Hazardous liquid filling machines are specialized equipment designed to handle flammable, corrosive, or toxic substances. The primary goal in designing these machines is to mitigate any potential sources of ignition or contamination during the filling process. This involves adhering to industry standards and utilizing components specifically rated for hazardous environments.
Key Design Considerations
Mitigating Ignition Sources
To prevent ignition of hazardous products or their fumes, it’s crucial to eliminate potential sources of sparks or heat. This is achieved by:
- Using Class I Division 1 Rated Motors: These motors are designed for environments where flammable gases or vapors may be present.
- Implementing Intrinsically Safe Devices: Components such as photo eyes and proximity sensors are designed to operate with low voltage, ensuring they do not produce sparks.
- Pressurized and Purged Control Panels: Control panels are built to be pressurized and purged with safety barriers, ensuring that any potential hazardous gases are kept out, and communication with the Programmable Logic Controller (PLC) is maintained via Ethernet IP.
Selecting Appropriate Components
Choosing the right components is vital for safety and functionality:
- Intrinsically Safe Field Devices: Utilizing low voltage, intrinsically safe electronics minimizes the risk of ignition.
- Solenoid Manifolds: Panel-mounted and sealed manifolds ensure that all air handling ports are outside the panel, with electronic valving inside the pressurized and purged panel.
Control Panel Placement
In highly hazardous locations, it’s often best to position the controls enclosure away from the filling machine. This setup involves:
- Remote Control Enclosures: Locating all electrical controls outside the hazardous environment.
- Detailed Utility Drawings: Providing comprehensive wiring and pneumatic schematics to connect the controls to the machine.
- Flexible Operation: Allowing machine functionality to be managed either remotely or via hazardous-duty tablets within the classified area.
Compliance with Industry Standards
When an area is classified as hazardous, it’s the plant’s responsibility to design systems and source machinery that conform to established standards. At D&R Packaging, we collaborate closely with our clients to:
