NEW MEXICO MILITARY INSTITUTE Safety Training Presentations Ergonomics Program 29 CFR 1910.900


Goals Musculoskeletal disorders (MSD) Summary of the Ergonomics Standard Quiz

What Is Ergonomics?: 

What Is Ergonomics? Science of fitting jobs to the people who do them Goal is to reduce work- related MSD when their jobs require repetitive reaching, bending, lifting, using force, working with vibrating equipment, and doing other repetitive motions

What Are MSDs?: 

What Are MSDs? Muscles Nerves Tendons Ligaments Joints Spinal discs

Common MSDs: 

Common MSDs Carpal tunnel syndrome Tendinitis Trigger finger Raynaud’s syndrome De Quervain’s disease Rotator cuff tendinitis Carpet layers’ knee Herniated spinal disc Low back pain

Signs of MSDs: 

Signs of MSDs Less strength for gripping Less range of motion Loss of muscle function Inability to do everyday tasks

Common Symptoms of MSDs: 

Common Symptoms of MSDs Painful joints such as wrists, shoulders, forearms, knees Pain, tingling, numbness in hands or feet Shooting pain in arms or legs Swelling, inflammation, burning sensation Fingers or toes turning white Back or neck pain or stiffness

Report Signs or Symptoms of MSDs: 

Report Signs or Symptoms of MSDs Permanent disability may result if not reported early Employer is required to respond promptly to your report Report signs or symptoms of MSDs to your supervisor or Human Resources representative Report MSD hazards


Repetition Same motion over and over puts stress on muscles and tendons How often the movement is repeated Speed of the movement Number of muscles involved Required force

Forceful Exertions: 

Forceful Exertions Amount of physical effort required to perform a task Effort needed to control equipment or tools Type of grip Weight of object Body posture Type and duration of the task

Awkward Postures: 

Awkward Postures Reaching Twisting Bending Kneeling Squatting Working overhead Holding fixed positions

Contact Stress: 

Contact Stress Pressing your body against a hard or sharp edge Puts pressure on nerves, tendons, and blood vessels Allowing your wrists to rest on the keyboard when typing Holding tools with hard handles


Vibration Sanders Grinders Chippers Routers Drills Saws


Goals Musculoskeletal disorders (MSD) Summary of the Ergonomics Standard Quiz

Response to MSD Report: 

Response to MSD Report Employer determines if report is an MSD incident Employer provided access to a healthcare provider Wages and benefits protected while on light duty or off work to recover Employer analyzes your job for MSD hazards Employer takes steps to reduce MSD hazards

MSD Incident: 

MSD Incident Requires medical treatment beyond first aid Assignment to light duty or temporary time off work for recovery MSD signs or symptoms that last seven or more consecutive days

Employer’s Response to MSD Incident: 

Employer’s Response to MSD Incident Basic Screening Tool: Identifies risk factors that could lead to MSD hazards Action Trigger: When risk factors on the job meet the levels of exposure in the Basic Screening Tool Now a full blown ergonomics program must be implemented

Management Leadership and Employee Participation: 

Management Leadership and Employee Participation MSD reporting and response system Designate persons with authority and resources to run the program Policies do not discourage employee participation or reporting of MSDs Employees participate in development, implementation, and evaluation of ergonomics program

MSD Management: 

MSD Management Employee provided with access to a health care professional Evaluation and follow-up of MSD incident Temporary work restriction

Work Restriction Protection (WRP): 

Work Restriction Protection (WRP) 100% wages/benefits while on light duty 90% wages and full benefits if removed from work WRP benefits last only a limited time Second opinions can be obtained by employee or employer

Job Hazard Analysis: 

Job Hazard Analysis Determine whether MSD hazards exist Implement control measures to reduce the hazards Employee involvement in identification and control is required Training for employees and supervisors in affected jobs

Evaluate Ergonomics Program: 

Evaluate Ergonomics Program Employer must make sure the program is effective Ask employees for their opinions Ensure hazards are being addressed Make necessary changes


Recordkeeping Reports of MSDs or signs/symptoms of MSDs Responses to reports Job hazard analyses Hazard control measures Ergonomics program evaluations Records of work restrictions and doctor’s written opinions Employees may have access to these records


Goals Musculoskeletal disorders (MSD) Summary of the Ergonomics Standard Quiz


Summary Recognize MSD signs and symptoms Understand MSD hazards Learn to take steps to control MSD hazards Report MSDs Participate in the Ergonomics Program


Quiz 1. Name one risk factor that determines if repetition contributed to an MSD: _________________________. 2. Loss of the muscle function is a sign of an MSD. True or False 3. MSDs are injuries to nerves and ___________________. 4. Name a vibrating tool that could contribute to an MSD: _____________________________________________. 5. An MSD incident can be defined as MSD symptoms that last seven or more consecutive days. True or False

Quiz (cont.): 

Quiz (cont.) 6. Describe a common MSD symptom: ________________. 7. Describe an awkward posture that you may experience while conducting your job: _______________________. 8. What does contact stress put pressure on that may result in an MSD? _____________________________________ 9. Employee participation is not needed for an effective Ergonomics Program. True or False 10. The type of grip is a risk factor to consider when evaluating jobs with forceful exertions. True or False

Quiz Answers: 

Quiz Answers 1. How often motion repeated, speed of movement, number of muscles involved, or required forces 2. True 3. Soft tissue 4. Sander, grinder, chipper, router, drill, saw True 6. Painful joints, tingling or numbness, shooting pain, swelling, pale fingers, back or neck stiffness 7. Reaching, twisting, bending, kneeling, squatting, working overhead, holding fixed position 8. Nerves, tendons, or blood vessels 9. False; employee participation is essential and fundamental 10. True
