Understanding Common Violations of ANSI B20.5.9.3: Guarding Nip and Shear Points

ANSI B20.5.9.3 sets the standard for guarding nip and shear points on machinery, an essential aspect of workplace safety. Nip and shear points, where two parts move together and can trap or crush an object or body part, pose significant hazards if not properly guarded. In my experience working with clients across various industries, I've seen several common violations that compromise safety and compliance.

Inadequate Guarding

The most frequent violation I encounter is the use of inadequate or makeshift guarding solutions. Often, I find that companies have installed guards that do not fully cover the nip and shear points or are easily removable, which defeats their purpose. Proper guarding must be robust, securely attached, and designed to prevent any part of the body from entering the danger zone.

Lack of Regular Inspections

Another common issue is the lack of regular inspections and maintenance of guards. Over time, guards can become damaged or misaligned, reducing their effectiveness. Based on my observations, many businesses fail to establish a routine inspection schedule, which leads to non-compliance with ANSI B20.5.9.3. Regular checks are crucial to ensure that guards remain in good working order and continue to protect workers effectively.

Insufficient Training

Insufficient training on the importance of guarding and how to properly use and maintain guards is a significant problem. Employees need to understand the risks associated with nip and shear points and the role of guards in preventing accidents. From my experience, when training is inadequate, workers may bypass or tamper with guards, leading to potential injuries and violations of safety standards.

Failure to Use Alternative Safety Measures

ANSI B20.5.9.3 allows for alternative safety measures if they provide equivalent protection to guarding. However, I've noticed that many companies do not explore these options or implement them incorrectly. For instance, using interlocked guards or presence-sensing devices can be effective alternatives, but they must be properly installed and maintained to ensure safety.

Documentation and Record Keeping

Lastly, poor documentation and record keeping can lead to violations. Companies need to maintain detailed records of their guarding solutions, inspections, maintenance activities, and training programs. In my work, I often find that businesses lack comprehensive records, which can make it difficult to demonstrate compliance during audits or inspections.

Understanding and addressing these common violations is crucial for maintaining a safe working environment and ensuring compliance with ANSI B20.5.9.3. By focusing on proper guarding, regular inspections, comprehensive training, exploring alternative safety measures, and maintaining thorough documentation, businesses can significantly reduce the risk of accidents and violations.
