5 Missing Guards that Can Shut Down Your Entire Line
Overview
Today’s manufacturing facilities are well protected against catastrophic safety hazards. This is due to increased regulations and a greater emphasis on safety in the workplace that has come into place within the last decade.
What’s more likely to shut down your manufacturing line are the small, seemingly insignificant, safety hazards that are often overlooked; such as a propped open gate, or a missing guard. These small misses can cause big OSHA violations and halt production, causing loss in productivity, as well as potential accidents. Further, these oversights contribute to the over 400,000 nonfatal workplace injuries that occur in the United States every year.
Leveraging often overlooked and minor safety compliances, coupled with a robust safety program, can reduce workplace injuries by up to 40%. This creates better employee morale and can save a company significant money by diverting costs from compensation payouts to revenue-generating initiatives.
This blog post will explain some of the common mistakes companies make on the manufacturing floor and how WireCrafters machine guarding, access control gates, modular wall panels and more can help keep manufacturing plants safer and more efficient.
1. Missing Interlocked Access Gates
Problem: It might seem like a simple fix to prop a gate open for “just a minute,” but when gates are not interlocked, or the interlock is bypassed, anyone (including unauthorized personnel) can enter an energized cell. The moment an incident occurs, you’re facing emergency responses, investigations, and potential citations.
Solution: Add hinged or sliding doors equipped with card readers, remote push buttons, and full-width push bars for gate access control. WireCrafters 840 style wire mesh panels support door packages that integrate with existing controls.
Tips:
- Ensure door frames have the hardware necessary to implement interlocking panels.
- Define entry rules (badge/PIN, supervision key) based on risk tier prior to installing access control systems.
2. Missing Perimeter Barrier Panels Around Automated Cells
Solution: Easily install fully framed woven or welded wire panels that bolt to posts and stack to required height. These welded wire mesh panels provide a modular perimeter that can be installed quickly with standard tools and provide continuous, visible protection. Add in welding screens for additional safety.
3. Missing Reach‑Through Protection (Wrong Mesh Aperture)
Problem: If mesh openings are too large near pinch points or conveyors, hands could reach through to energized hazards. One recordable in this area and the whole line could go down.
Solution: Ensure mesh aperture is in line with ANSI/ISO standards. The larger the opening in the guard (also known as the mesh aperture) the farther the guard must be placed from the hazard to prevent hands, fingers or arms from reaching through. Wirecrafters 10 gauge 2×2 welded wire panels have tighter apertures for high-risk zones.
Tips:
- Review the table below to determine the proper mesh aperture and minimum safety distances. Distances are based on anthropometric data for adults (14+ years) and assume no additional obstructions.
ANSI/ISO Safety Distance Table
| Opening Size | Minimum Safety Distance |
|---|---|
| ≤ 4 mm (0.16 in) | 2 mm (essentially flush) |
| ≤ 6 mm (0.24 in) | 10 mm |
| ≤ 8 mm (0.31 in) | 80 mm |
| ≤ 12 mm (0.47 in) | 120 mm |
| ≤ 20 mm (0.79 in) | 850 mm |
| > 120 mm (4.72 in) | Whole-body access possible → Not allowed without additional measures |
Examples in determining setback distance:
- If your mesh opening is 50 mm square, the required setback is 850 mm (because an arm can reach through).
- If you reduce the opening to 8 mm, the required distance drops to 80 mm.
Other Tips:
- Add solid sheet metal panels for necessary hazards where reach-through risk remains a problem.
4. Missing Overhead/Ceiling Panels for Containment
Problem: Maintenance and safety managers might assume cells are safe with only side panels. However, many injuries can still occur if ceiling panels are missing. Examples of injuries due to lack of overhead wire mesh panels include ejected parts, broken tooling, or overhead falls – all of which can injure personnel outside the cell.
Solution: Utilize the same welded wire panels used for the walls to build the ceilings, creating full enclosures that allow HVAC, light and sprinklers to operate as designed. This is a simple way to ensure full coverage and complete safety within a machinery cell.
Tips:
- Confirm fire code requirements for open mesh ceilings.
- Use reinforced spans and intermediate support on wide bays.
5. Missing Controlled Entry Zones (Driver/Visitor & Maintenance Boundaries)
Problem: Many manufacturing facilities have uncontrolled entries or maintenance areas, leading to tailgating and shortcut culture. This allows for unauthorized personnel to enter hazardous areas, increasing the risk of injury and stopping the line.
Solution: Install a Driver Access Cage or tool/maintenance cribs with access control hardware, such as push bars, card readers, etc. To keep the public, vendors and maintenance separate from active production.
Tips:
- Anchor wire cages to walls or free-stand; size to fit traffic patterns.
- Add audit-ready locking options and signage at all entries.
Quick Floor Audit: Spot the “Shutdown Triggers”
Now that you’ve learned more about what missing guards can shutdown your line, you an be more attune to your surroundings and prepared to take action to increase your safety and efficiency.
Use this rapid check before your next shift:
- Any gate that can be opened without an interlock or badge?
- Any panel removed for “temporary access”?
- Any mesh near hazards that allows finger or hand reach‑through?
- Any overhead opening above a high‑energy process?
- Any uncontrolled doorway where drivers, visitors, or maintenance can tailgate?
If you’ve been able to answer “yes” to any of these questions, you might need to reevaluate your machine guarding.
