Understanding ANSI B20.5.9.3: Guarding Nip and Shear Points in Casinos
In the bustling environment of a casino, safety cannot be left to chance. The ANSI B20.5.9.3 standard, specifically addressing the guarding of nip and shear points, is crucial for ensuring the safety of both employees and patrons. This standard mandates that nip and shear points on machinery, like conveyor systems often found in casinos for handling chips, cash, and other items, must be guarded unless alternative safety measures are in place.
Why Guarding Matters in Casinos
Casinos are unique workplaces with a high volume of both people and mechanical operations. Nip and shear points, where two parts move together or past each other, pose significant risks. In a casino setting, these hazards can occur in areas like money counting rooms or behind-the-scenes operations where conveyors are used. Without proper guarding, the risk of accidents, such as entrapment or amputation, increases dramatically.
Compliance with ANSI B20.5.9.3
To comply with ANSI B20.5.9.3, casinos must ensure that all nip and shear points are either guarded or that other effective safety measures are implemented. This could involve installing physical barriers, using safety interlocks, or employing other engineering controls. For specific types of conveyors used in casinos, section 6 of the standard provides detailed guidance on what is required.
Practical Implementation
In my experience, implementing these safety measures in a casino involves a thorough risk assessment. We walk through the facility, identifying all potential nip and shear points. For instance, in a casino's cash handling area, we might find a conveyor system used for sorting and transporting chips. Here, we would install guards to prevent access to the moving parts, ensuring that employees cannot accidentally get caught.
It's not just about installing guards. Training is key. Employees need to understand the purpose of these guards and the dangers of bypassing them. Regular safety audits and maintenance checks are also essential to ensure that the guards remain effective and in compliance with ANSI B20.5.9.3.
Resources and Further Reading
For those looking to dive deeper into ANSI B20.5.9.3 and its application in casinos, the following resources can be invaluable:
- American National Standards Institute (ANSI) - For the full text of the standard.
- Occupational Safety and Health Administration (OSHA) - For additional guidance on machinery safety in workplaces.
- National Fire Protection Association (NFPA) - For related safety standards in casino environments.
Based on available research, individual results may vary, but adhering to these standards significantly reduces the risk of accidents in casinos. By understanding and implementing ANSI B20.5.9.3, casinos can ensure a safer environment for everyone.
