OH&S

Occupational health and safety (OH&S) involves ensuring that workplaces such as piggeries are free of hazards for the health of its workers.

OH&S Legislation is made and administered at the State government level. States provide farm safety inspectors to assist farmers in maintaining a safe workplace. However, farms are excluded from much of the regulatory force of these acts, such as obligations to provide amenities.

Noise Exposure
Piggery staff are at risk of noise induced hearing loss from pigs squealing at over 110db. Piggery staff may be exposed to these noise levels for long periods of time.

This issue should be addressed by using husbandry measures that reduce squealing (eg. feeding systems) or by using hearing protection.

Respirable Disease
Airborne particles exist within pigs housed in high concentrations. These particles are small and usually not visible, they are suspended in the atmosphere, can carry odours, and may contain micro-organisms. These particles include feed dust, pig protein (urine, dander, and serum), faeces, mould, pollen, grain mites, and mineral ash.

Piggeries may also contain harmful gases, primarily from decomposing animal wastes, poor ventilation, and faulty heating systems.

Manual Handling Issues
Injury may be caused by manual handling of pigs. These issues are best addressed by a good piggery design and layout.
