Tray 1-A: NIOSH Investigations of WMSDs in Work Settings |
SIC Codes: 3231 3261 3261 3291
| Standard industrial classification (SIC) |
3231 Manufacturing (Glass products) |
| Work setting and tasks |
Specialty glass and mirrors. Grinding, buffing, polishing, and buffing tasks. |
| Work-related musculoskeletal problems found |
Upper limb and neck |
| Ergonomic risk factors found |
Repetitive and forceful exertions, awkward postures |
| Recommendations |
Engineering control recommendations ranged from automating aspects of certain jobs to using special fixtures to hold the products. Continued job rotation for workers involved in certain tasks was suggested as an administrative control. |
| HETA/NTIS reference no. |
HETA 89–137–2005 NTIS order no. PB–91–108–134 |

| Standard industrial classification (SIC) |
3261 Manufacturing (Pottery products) |
| Work setting and tasks |
Ceramic plumbing fixture manufacturing. The machine-paced tasks include repeated lifting and moving of toilet bowls weighing up to 70 lb. |
| Work-related musculoskeletal problems found |
Back |
| Ergonomic risk factors found |
Repetitive and forceful exertions, awkward postures, heavy lifting, and paced work |
| Recommendations |
Arrange for two-worker lifts of heavy product loads. Modify height of conveyor and adjoining workstations to facilitate access, ease transfer of product in the course of the manufacturing process. Consider alternatives to the paced work and incentive system that would moderate and more evenly distribute the physical effort. |
| HETA/NTIS reference no. |
HETA 88–237–L1960 NTIS order no. PB–89–230–270 |

| Standard industrial classification (SIC) |
3261 Manufacturing (Pottery products) |
| Work setting and tasks |
Lifting and loading jobs (as much as 73 lb) in a plant manufacturing ceramic plumbing fixtures. |
| Work-related musculoskeletal problems found |
Back |
| Ergonomic risk factors found |
Repetitive exertions, awkward postures, heavy lifting |
| Recommendations |
Furnish mechanical lift devices to relieve manual handling of heavy product loads. Redesign carts and workstations to facilitate transfer of product in course of manufacturing process. |
| HETA/NTIS reference no. |
HETA 82–229–1286 NTIS order no. PB–84–209–741 |

| Standard industrial classification (SIC) |
3291 Manufacturing (Nonmetal mineral products) |
| Work setting and tasks |
Abrasive products manufacture with focus on press operating tasks. |
| Work-related musculoskeletal problems found |
Limited to evaluation of potential ergonomic risk factors. |
| Ergonomic risk factors found |
Repetition, sustained awkward postures, forceful exertions, and contact forces. |
| Recommendations |
Guardrails should be adjustable and padded. Prohibit use of hand as "hammer."
Modify press to reduce awkward postures. Furnish training to employees about ergonomic hazards. Establish a medical surveillance program. |
| HETA/NTIS reference no. |
HETA 92–0001–2444 NTIS order no. PB–95–146–429 |
