Engineering and management measures to reduce environmental emissions and improve the work environment in swine barns

Project: MLMMI 07-02-05

Objective

The overall goal of this project is to assess the effectiveness of selected engineering and management measures in reducing ammonia (NH3) emissions, thereby reducing environmental emissions and protecting the health and safety of barn workers.

Specifically, this project aims to:

  1. Apply four types of engineering and management measures (oil sprinkling, low-protein diet, high level of cleaning, and manure pH manipulation) in swine production rooms, and
  2. Compare the occupational exposure to ammonia and dust of workers assigned to the experimental and conventional rooms. Exposure will be assessed using standard methods in accordance with the new Manitoba Workplace Safety and Health Regulations.

KEYWORDS: ammonia, odour, pH reduction, dust, emissions, manure, oil sprinkling, swine, occupational exposure.

Summary

The overall goal of this project was to assess teh effectiveness of selected engineering and management measures, namely canola oil sprinkling, low crude protein diet, high level cleaning, and manure pH manipulation in reducing NH3 and respirable dust concentration in swine production rooms.

As the engineering and management measures evaluated were not economically promising, attention should focussed on administrative measures and protective equipment to reduce worker exposure to airborne contaminants
