Machine Guarding Labels: Frequently Asked Questions and OSHA Safety Guidelines

Yes, it is. Machine guarding is covered in OSHA 1910 Subpart O, with1910.212 detailing the general requirements for all machines. The standard requires the use of one or more methods of machine guarding to protect operators and other employees in the machine area from hazards. These guards should be affixed to the machine where possible and secured elsewhere if attachment to the machine is not possible.Information about guarding different machines and parts is also provided in the standard. 

Fixed, adjustable, self-adjusting and interlocking barrier guards are some of the most commonly used machine guards. Fixed barriers permit stock feeding but do not let the operator reach the danger area. Adjustable barriers, as the name suggests, can be adjusted for a variety of production operations. Self-adjusting barriers move according to the size of the stock entering the point of operation. These guards stay in place when the machine is at rest and push away when stock enters the point of operation. Interlocking barrier guards shut off or disengage power and prevent machine start-up when the guard is open. 

Each of these guards has distinct advantages and limitations, and this helpful OSHA resource aboutSafeguarding Equipment And Protecting Employees From Amputations presents every aspect in detail.

Machine guarding labels are safety communication and awareness devices that warn individuals of any impending, approaching or present hazard related to machine operation. These are a type of adhesive signs placed strategically on machines and usually designed in accordance with the OSHA standard1910.145 about accident prevention signs and tags.

The different headers onmachine guarding labels correspond to the different hazard severity levels associated with the machine. The DANGER header signifies that the hazardous situation will result in death or serious injury if not avoided. Where the hazard may cause death or serious injury, the WARNING header is used. The CAUTION header implies the possibility of minor or moderate injury if the marked hazard is not avoided. 

Like other safety labels, machine guarding labels should be placed in close proximity to the hazard. As per the location specifications mentioned in ANSI Z535.4 9.1, allsafety labels and signs should be readily visible to the workers they are meant for. The placement should be such that it gives the viewer sufficient time to take appropriate action against the hazard. 

Amputations are some of the most common, serious, and debilitating injuries in the workplace. To create a safe work environment and protect workers from these injuries, employers first must recognize, identify, manage, and control amputation hazards commonly found in the workplace. These are usually caused by the mechanical parts of machines and their automated or manual motion. Also, the activities performed by workers during mechanical operations contribute to increasing the number of injuries. 

Employers can implement safe work practices, employee training, and administrative controls to help prevent and control amputation hazards. Using machine safeguarding equipment, including guards and safeguarding devices, is one of the most effective ways to limit the risk of amputation injuries while operating machinery. ThisOSHA factsheet about amputations throws light on its causes, risk factors, standards for prevention, employer responsibilities, and worker’s rights.
