Step 4: Look-up Posture Score in Table A 4 3 4 4 4 5 6 7 8 8 9 9 9 Using values from steps 7-9 above, locate score in Table B Posture Score B Using values from steps 1-3 above, locate score in 5 4 4 4 5 6 7 8 8 9 9 9 9 Step 11: Add Coupling Score + Table A Posture Score A 6 6 6 6 7 8 8 9 9 10 10 10 10 Well fitted handles and mid range power grip, good: +0

+ 7 7 7 7 8 9 9 9 10 10 11 11 11 Acceptable but not ideal hold or coupling Step 5: Add Force/Load Score 8 8 8 8 9 10 10 10 10 10 11 11 11 acceptable with another body part, fair: +1 Coupling Score If Load < 5kgs: +0 9 9 9 9 10 10 10 11 11 11 12 12 12 Hand hold not acceptable but possible poor: +2

If Load is 5 to 10kgs +1 Force/Load Score 10 10 10 10 11 11 11 11 12 12 12 12 12 No handles, awkward, unsafe with any body part, = If load >22lbs +2 11 11 11 11 11 11 12 12 12 12 12 12 12 Unacceptable: +3

Adjust: If shock or rapid build up of force:add +1 = 12 12 12 12 12 12 12 12 12 12 12 12 12 Step 12: Score B, Find column in Table C Step 6: Score A, Find Row in Table C Add values from steps 10 & 11 to obtain Add values from steps 4 & 5 to obtain Score A. Score B> Find Column in Table C and match with Score A in Score B Find row in Table C. Score A row from step 6 to obtain Table C score.

Table C Score Activity Score Step 13: Activity Score Scoring: +1 1 or more body parts are held longer than a minute (static)

1 = Negligible risk +1 Repeated small range actions (more than 4x per minute) 2 or 3 = low risk, change may be needed +1 Action causes rapid large range change in postures or unstable base 4 to 7 = medium risk, further investigation, change soon 8 to 10 = high risk, investigate & implement change 11+ = very high risk, implement change Final REBA Score
