Operator Protection; Repetitive Motion; Hearing Protection - Stanley QB Expert Instruction Manual

5.1.1 Operator Protection

ROTATING EQUIPMENT
To Avoid Injury:
• Always wear eye and foot protection when operating, installing, or maintaining power tools, and when in
areas where power tools are being used, maintained, or installed. Some applications may require the use
of safety glasses and face shields. Use eye protection that conforms to ANSI Z87.1.[3] and ANSI Z41-PT99M
I/75 C/75.
• Always stay alert when operating tools and/or their accessories. Do no operate tools and/or their
accessories while tired, under the influence of drugs, alcohol or any other mind-altering substance.
• Repetitive work motions or vibration may be harmful to your hands, arms, shoulders or back.
• Use suitable protective equipment and work methods whenever an application presents a hazard.

5.1.2 Repetitive Motion

The use of power tools may involve highly repetitive motions of the fingers, hands, wrists, and shoulders. These
repetitive motions can lead to cumulative trauma disorders (CTD). Many personal and workplace factors can
contribute to these disorders.
Currently available data have identified the following risk factors. These risk factors are not necessarily causation
factors of CTDs. The mere presence of a risk factor does not necessarily mean there is excessive risk of injury.
Generally, the greater the exposure to a single risk factor or combination of factors the greater the risk for CTDs.
• Forceful exertions and motions
• Extreme postures and motions
• Repetitive exertions and motions
• Intended duration of exertion, postures, motions, vibration, and cold
• Insufficient rest or pauses
• Work organization risk factors
• Environmental risk factors
These risk factors span job design and content, operator training, work method, work pace, work environment,
proper tool selection and other work place factors beyond the control of the tool manufacturer. Tool owners and
employers should analyze jobs for all of the risk factors identified above and take appropriate action.
Some measures which may reduce the risk of CTDs:
• Use minimum hand grip force consistent with proper control and safe operation.
• Keep wrists as straight as possible.
• Avoid repetitive movements of the hands and wrists.
• If wrist pain, hand tingling, numbness, or other disorders of the shoulders, arm, wrist or finger occur; notify
supervisor, discontinue task, reassign user to a different job; if relief is not found contact experts skilled in
treating such disorders.
Wrist supports, torque reaction devices, and balancers should be used if it can be determined that such devices
can reduce the risk of repetitive motion disorders.

5.1.3 Hearing Protection

Power tool operators and adjacent personnel may be exposed to excessive sound levels. The tool in use is
generally only one of many sources of noise that an operator experiences. Other tools and machines in the area,
joint assembly noise, work processes, and other ambient noise sources all contribute to the sound level operators
