Q

NIOSH Lifting Equation
RWL = LC X HM X VM X DM X AM X FM X CM

A

LC - Load constant
HM - Horizontal distance of hands from midpoint between ankles
VM - vertical distance of hand from the floor
DM - Vertical travel distance of between origin and destination
AM - angular displacement of the load from the Sagittarius plane in degrees
FM - average frequency of lifts per minute
CM - coupling or handle adequacy

Q

Composite Lifting Index

A

Determines the additive effect of several tasks and is obtained by ranking the tasks in decreasing order of physical difficulty as indicated by the single task lifting index of each task. Better estimates the risk associated with multi-tasks manual lifting

Q

Rapid Entire Body Assessment

A

Used to assess static, rapidly changing and unstable postures. Assess handling loads

25
Rogers Muscle Fatigue Analysis
Studies physiological massless fatigue at different effort levels and holding times. Muscular effort in relation to recovery time
26
Moore-Garg Strain Index
Method of evaluating jobs to determine if they expose workers to increased risk of developing MSDs of the upper extremity
27
Rapid Upper Limb Assessment
Qualitative assessment used to assess posture, force and movement associated with tasks where the worker is seated or standing without moving about
28
Work Hardening
A process that is designed to restore the employee’s physical capacity and functional abilities after an injury
29
Job Rotation
Having employees rotate tasks that use different body segments or different frequency/forces
30
Restricted Duty
Medical term indicating that an employee may return or work under specific guidelines or restrictions
31
Fit for Duty Exam
Exam to determine if employees are ready to return to work
32
Trench Foot
Caused by prolonged exposure to a cold temperature that usually above freezing and damp, sometimes unsanitary conditions
33
Tenosynovitis
Inflammation of the tendon sheath where muscle connects to bone
34
Trigger Finger
Occurs due to repeated and prolonged use of the trigger finger
35
Thoracic Outlet Syndrome
When blood vessels or nerves in the space between your collarbone and your first rib (thoracic outlet) are compressed
36
Illuminance
The amount of light falling onto a given surface area
37
Luminance
The intensity of light emitted from a surface
38
Lux
Measure of illuminance, the total amount of light that falls on a surface
39
Lumens
Measures the amount of light that is emitted by a single light source, and in all directions
40
Candela
The international system of units (SI) measure of luminous intensity 1 Candela = 1 Lumen
41
Workplace Wellness Program (WWP)
Proactive activities companies take to prevent injury/illness or to detect illnesses early to improve recovery

Future of Work (FOW)
Identify new research solutions, practical approaches, and partnership opportunities to address the future of work
43
Prevention through Design (PtD)
To prevent or reduce occupational injuries, illness, and fatalities through the inclusion of prevention considerations in all designs that impact workers
