Guard pinch point

Some hazards can be rectihed in a short time, and some may take longer to fix. Whatever the scheduling, some form of temporary measures need to be put in place while the hazard is being permanently fixed. For example, while upgrading machine guarding that has exposed pinch points, a temporary barrier can be erected around the machine while it is being modified. Once hazards have been identified, they should receive immediate attention where possible, as the credibility of the new safety direction is at stake. 

Figure 13-4. The danger line for in-running rolls is where the rolls are 3/8 in apart. The danger line determines the pinch point. The distance from the 3/8 in pinch point becomes the reference for guard placement.

Two in-running rolls (with no feed table) compress parts fed into them. The rolls are each 4 in. in diameter. There is a 1/8 in. gap between them and the material is 5/8 in. thick before compression in the rolls. A guard will protect the pinch point. The opening for the material will have a 1/8 in. clearance. Determine ...

This chapter will focus on those warehouse hazards that need physical guarding or identification in some way. The proper design and construction of many physical safeguards requires that they be not only secure and substantial, but that they also meet OSHA guidelines. Something as basic as a physical pinch point exposure that requires a barrier guard should be of concern to each employee. Employees that work and travel through various parts of the warehouse could easily be exposed to many additional physical risks. 

Conveyors have moving parts. Various pinch points exist in those areas that help the conveyor move product. A drive chain on a sprocket may move the rollers of the conveyor, but left unguarded this hazard can cause very serious hand injuries. The guard must be designed and mounted to completely seal off the hazards. This includes a full enclosure guard that does more than just cover the front of the drive chain. An employee could easily place a hand on the partial... 

The guarding on the portable compressor in Figure 6-4 is excellent. A serious pinch point always exists on drive belts. In some cases, the pulley belts may be mounted eight or more feet from the floor and be considered safe because of distance. But it must be remembered that if maintenance is needed on the motor, someone must gain access to the motor and at... 

All moving parts must be guarded. These moving parts would involve the usual pinch points for gears and drive mechanisms. 

Some individuals in the material handling industry argue that the improvements in conveyor safety have not kept pace with improvements in other machines and processes. Some of the noticeable improvements, however, include full enclosures of pinch points such as chain and sprocket transmissions, perimeter pull cords for emergency stops, audible alarms and a delayed start-up function, pop-out rollers, improved warning labels, and interlock guards that are designed to shut off the power if removed. 

Since many conveyor injuries occur because of poor initial layout of the system, be sure to consider auxiliary hazards when installing the unit. These include guarding, electrical, exits, side-hinged gates, alarms, lights, and hidden pinch point hazards.
