MACHINE GUARDS PREVENT SERIOUS
INJURIES

A company in Orrington ( Maine, USA ) was hit with $20,500 in penalties from the Occupational Safety and Health Administration (OSHA') following the death of a maintenance worker in its trash‑to‑energy plant last year.
The worker was sweeping around an operating conveyor when the handle of his broom became caught in the nip point 2 between a roller and the conveyor framework. He died as a result of the accident.
An OSHA inspection found that the conveyor wasn't properly equipped with machine guards that would have prevented the accident.
OSHA states that at least one method of machine guarding must be provided to protect employees in the machine area from hazards created by point of operation, ingoing nip points. rotating parts, flying chips and sparks.
The point of operation. the area on the machine where work is actually performed upon the material being processed, requires guarding if an injury to an employee is possible. These devices should be designed and constructed to prevent the operator from having any part of his body in the danger zone during the operating cycle.
All guards should be affixed to the machine where possible. and secured elsewhere if attachment to the machine is not possible. And obviously, the guard should not be a hazard itself.
Some OSHA‑approved guarding methods include barrier guards and electronic safety devices: 
Barrier guarding is the most commonly seen device. It is available in several forms, such as heavy steel rails mounted to structural steel columns or wire panels that are bolted to steel posts. Most of these guards are painted a bright, safety yellow and are used to keep workers a safe distance away from high‑risk areas.
Electronic devices usually feature infrared eyebeams that create a screen between a hazardous machine and personnel. If the beams are broken by an object or appendage, the device sends a signal to the machine to stop moving.
People often distrust electronic devices because of the possibility of a system failure.
These are just a small sampling of the guarding devices on the market, so be sure to look into all the options to find one that suits your facility's needs.
Keep in mind that while some are more costly than others, all will save thousands of dollars by protecting workers from harm.

WE CAN HELP YOU GUARD YOUR MACHINES

SCIENTIFIC TECHNOLOGIES INC.
Physical barriers were once the only way to safeguard workers from potentially hazardous machinery.
No more! Safety light curtains instead form a virtual barrier.
When breached, the machine or process stops.
An example of our solutions: Hydraulic Press Guarding
A safety light curtain provides an "L" shaped optical pattern protecting machine operators from a hydraulic press. The horizontal section prevents the operator from standing between the machine hazard and the vertical section without being detected.
