The psychosocial section in incomplete. What are some of the implications to safety & health based on the responses provided the worker during the interview?
For this section: Do not just report back what the answers: Strongly Agree, Agree, Disagree or Strongly Agree.
Make sure to provide comments/observations why certain items may be hazards.
Example: If the worker strong disagree to this question: "I have enough time to get the job done";
This could be a hazard that a work will have to work fast and may experience stress.
HAZARD ZONE JOBS CHECKLIST |

Calculator for Hand-Arm Vibration |
1. Find the vibration value for the tool. (Get it from the manufacturer look it up at this website http://wwwn.cdc.gov/niosh-sound-vibration/Results.aspx?tt=6 On the graph below mark the point on the left side shown as Vibration value.
Not Applicable
Vibration
m/s2
Not Applicable
Duration
Hrs.
2. Find out how many total hours per day the employee is using the tool and mark that point on the bottom of the chart below.
3. Trace a line into the graph from each of these two points until they cross. No vibration tool used
4. Interpretation
a. If that point lies in the crosshatched “Hazard” area above the upper curve, then the vibration hazard must be reduced below the hazard level or to the degree technologically and economically feasible.
b. If the point lies between the two curves in the “Caution” area, then the job remains as a “Caution Zone Job.”
c. If the point falls in the “OK” area below the bottom curve, then no further steps are required.
|
Note: The caution limit curve (bottom) is based on an 8-hour energy-equivalent frequency- weighted acceleration value of 2.5 m/s2. The hazard limit curve (top) is based on an 8-hour energy-equivalent frequency- weighted acceleration value of 5 m/s2.
