Types of Guards and Safety Devices for Enhanced Protection
These are the types of effective safety guards that help keep worksites and employees protected:
. Fixed GuardsThese permanent covers block access to hazardous parts of equipment. They stay in place and suit tools that don’t need frequent changes. For example, a fixed guard on a saw effectively blocks contact with the blade, meeting safety requirements.
. Interlocked Guards
These include a mechanism that stops operation when opened or removed. This is important for tools needing upkeep or adjustments, as it stops accidental startup.
For instance, an interlocked guard on a conveyor stops moving parts unless the equipment is powered down first. They are designed so that opening the guard automatically cuts power and halts motion.
. Adjustable Guards
These can be changed to fit different sizes of materials entering the equipment. They modify openings based on the stock being processed, offering flexibility while maintaining protection.
An example is a self-adjusting guard on a stamping press that fits various sheet sizes, keeping employees protected.
. Additional Safety Devices
Beyond traditional covers, devices like light curtains, safety fencing and automated doors improve protection by detecting personnel and stopping operation before contact.
