Machine Safety and Guarding for Molded Pulp Lines: Protecting Operators Around Moving Equipment

Molded pulp lines combine presses, heated dryers, and moving conveyors, each with pinch, crush, and burn hazards. Machine guarding, interlocks, and lockout/tagout (LOTO) procedures are the core defenses. Following standards such as ISO 12100 for risk assessment and ISO 14120 for guards, plants cut serious-injury risk and keep lines running without incident.

The Scenario: Hazards around the line

Machine safety faces three challenges:

Pain Points

• Presses and conveyors create pinch and crush points that can injure operators;
• Heated dryers add burn hazards that require guarding and access control;
• Maintenance during running equipment needs lockout/tagout to prevent unexpected start-up.

The Solution: Three safety solutions

Safety is built with three controls:

1. Guarding and interlocks Physical guards and interlocks block access to pinch, crush, and burn points during operation.

2. Lockout/tagout procedures LOTO isolates energy during maintenance, preventing unexpected machine start-up.

3. Standards-based risk assessment Risk assessment per ISO 12100 and guards per ISO 14120 formalize hazard control.

The Result: A safe, incident-free line

With guarding, interlocks, and LOTO, plants cut serious-injury risk while keeping production running smoothly.
