Checklist
-
Reading across the page, determine if any of the conditions are present in the work activities. For many of the risk factors, two conditions are presented, which are the indicators for Caution and Hazard. Most of the conditions are based on duration. If the lower threshold condition is not met, the "no" box is checked. If the lower condition is met but the higher is not, then Caution is checked. If the higher condition is met (generally a longer period of time), then Hazard is checked. If only Caution boxes are checked, some risk is present. It is worthwhile to continue to monitor Caution level jobs for changes that might increase the risk and for the occurrence of injuries or symptoms. If one or more Hazard boxes are checked, a work-related musculoskeletal disorder (WMSD) hazard exists, and immediate action (further analysis or intervention) is recommended. The checklist is divided into four body zones • Low Back • Hand and Wrist • Neck and Shoulder • Knee Note: Washington State Department of Labor and Industries published two checklists (Caution Zone and Hazard Zone). This checklist is an attempt by a third party to combine the lists. See www.lni.wa.gov/Safety/Topics/Ergonomics/ServicesResources/Tools/ WISHA is the Washington Industrial Safety and Health Act.

WISHA Lifting Calculator
-
Note: If the job involves lifts of objects with a number of different weights and/or from a number of different locations, use Steps 1
through 5 above to:
1. Analyze the 2 worst case lifts—the heaviest object lifted and the lift done in the most awkward posture.
2. Analyze the most commonly performed lift. In Step 3, use the frequency and duration for all the lifting done in a typical workday. -
STEP 1 Enter the weight of the object lifted. kg
-
STEP 2 Select the number on a rectangle in the diagram that corresponds to the position of the person’s hands when they begin to lift or lower the objects. - select number
- Above shoulder 30 lbs./ 13.6 kg
- Above shoulder 40 lbs./ 18.1 kg
- Above shoulder 60 lbs./ 27.2 kg
- Waist to shoulder 40 lbs./ 18.1 kg
- Waist to shoulder 50 lbs./ 22.6 kg
- Waist to shoulder 70 lbs./ 31.7 kg
- Knee to waist 40 lbs./ 18.1 kg
- Knee to waist 40 lbs./ 18.1 kg
- Knee to waist 40 lbs./ 18.1 kg
- Below Knee 35 lbs./ 15.8 kg
- Below Knee 50 lbs./ 22.6 kg
- Below Knee 70 lbs./ 31.7 kg
-
STEP 3 Select the number that corresponds to the times the person lifts per minute and the total number of hours per day spent lifting. Note: For lifting done less than once every five minutes, use 1.0
