Datacenter Ergonomics Evaluator and Auditor Training
MODULE 03

Part 2: Evaluating Industrial Environments

Industrial and Environmental Ergonomics are the most common branches addressed in datacenters. Manual work in server aisles places strain on joints and muscles that differ from those affected by desk-based work.

Industrial ergonomic risks

Organized by body part: arms, hands, back, and legs experience different strain mechanisms while working on servers for extended periods.

Five joint groups carry most of the load in a server aisle: shoulders and elbows from reaching, wrists and fingers from gripping, and the back, knees, and ankles from crouching or kneeling. The categories below map to each marked point.

Arms / Shoulders

01

Arms positioned outward and upward while working on servers for extended periods.

What to look for
  • Arms positioned outward; work performed at a distance in front of the body (shoulder flexion)
  • Reaching overhead (shoulder abduction and extension)
  • Using tools or handling materials while arms are outward or overhead

Arms / Elbows

02

Arms positioned downward or close to the body while working on servers for extended periods.

What to look for
  • Arms positioned downward; work performed below waist level (elbow extension)
  • Arms close to the body; work performed above waist level (elbow flexion)
  • Using tools or handling materials with arms downward or close to the body

Hands

03

Hands positioned backward, forward, or sideways while working on servers for extended periods.

What to look for
  • Hands in a backward position (extension)
  • Hands in a forward position (flexion)
  • Hands in a sideways position (radial or ulnar deviation)

Fingers

04

Fingers pinched while working on servers for extended periods.

What to look for
  • Employees pinching fingers to grip small parts, materials, or tools

Back

05

Bending, twisting, or standing for extended periods while working on servers.

What to look for
  • Bending forward to do work (back flexion)
  • Bending backward to do work (back extension)
  • Bending sideways to do work (lateral bending)
  • Twisting at the waist while using tools or handling materials
  • Prolonged standing to complete job tasks

Legs / Knees / Ankles

06

Kneeling or crouching for extended periods while working on servers.

What to look for
  • Working in a kneeling position with knees on the floor
  • Working in a crouched position with knees bent and the upper body leaning forward
  • Kneeling or crouching with arms extended while using tools or handling materials

Back / Entire Body

07

Pushing and pulling server racks, or lifting and carrying heavy loads.

What to look for
  • Moving servers or racks manually without assistive devices
  • Lifting and carrying boxes or heavy wire bundles manually without assistive devices
3.2

Environmental ergonomic risks in industrial environments

Excessive noise, lighting, or temperature, plus PPE and signage checks specific to industrial spaces.

  • Employees in noisy areas with no hearing protection
  • Hearing protection signage in noisy areas
  • Employees over- or under-dressed for the type of room (e.g. wearing gloves in a control room)
  • Monitors without glare screens
  • Proper positioning of light fixtures in work areas

Knowledge Check

Q1. A technician repeatedly reaches overhead to rack servers. What risk category and mechanism does this describe?
Q2. An employee works in a crouched position with knees bent and their upper body leaning forward. What should the evaluator flag?
Q3. What should an evaluator look for when a rack is being relocated?
Q4. Which is an environmental ergonomic risk specific to industrial data center areas?
