To prevent risk of disease among workers exposed to on-the-job use of biosolids to fertilize agricultural lands or mine reclamation sites, NIOSH (National Institute for Occupational Safety and Health) has outlined recommended practices. Among them:
- Engineering controls and work practices should be used as first measures to prevent worker exposures to Class B biosolids during and after field application. Examples may include mixing Class B biosolids thoroughly into the soil where feasible; providing sealed, air-conditioned, filtered-air-recirculation cabs for heavy equipment used on the site; and avoiding disturbance of the material during the restricted period.
- If engineering controls are not feasible at a Class B biosolid site, or while engineering controls are being installed or maintained, personal protective equipment for workers should be provided and required. Equipment may include goggles, splash-proof face shields, respirators, liquid-repellent coveralls, and gloves.
- Hand-washing stations with clean water and mild soap should be provided, and cabs on heavy equipment should be cleaned of residual mud or dust after each use.
- Employers should provide periodic training about standard hygiene practices on the job.
The Hazard ID, along with other NIOSH documents, can be ordered through the NIOSH toll-free information number, 1-800-35-NIOSH (1-800-356-4674). The document is also available at www.cdc.gov/niosh/hidlist.html.
