Examples and Case Studies

Reducing Silica Dust Exposure in Construction

A mid-sized construction firm engaged an Industrial Hygienist to assess worker exposure to respirable crystalline silica during concrete cutting and demolition activities. Air sampling revealed exposure levels exceeding OSHA limits. Using a combination of wet-cutting methods, local exhaust ventilation, and strict PPE protocols, the hygienist worked with site management to implement controls, reducing exposures by over 70%. Training sessions were conducted to ensure worker compliance and understanding.

Key Takeaway: This case highlights the effectiveness of combining engineering controls with administrative measures and worker training to manage hazardous exposures in dynamic industrial settings.

Ergonomic Intervention in a Warehouse Environment

An Industrial Hygienist was called to identify reasons for high rates of musculoskeletal injuries in a large distribution warehouse. Through ergonomic assessments and direct worker interviews, the hygienist identified repetitive lifting and poorly designed workstations as primary contributors. Recommendations included adjustable lift tables, job rotation schedules, and worker ergonomics training. Follow-up assessments showed significant reductions in injury rates.

Key Takeaway: Systematic ergonomic evaluation and tailored interventions can dramatically improve worker safety and reduce injury-related costs.

Biological Hazard Control in a Healthcare Setting

A hospital faced challenges controlling airborne infectious agents in several patient care areas. The Industrial Hygienist performed ventilation evaluations, air sampling for biological contaminants, and assessed PPE usage. Ventilation system upgrades and revised PPE protocols were recommended and implemented.
