Points to Emphasize
Points to Emphasize
Minimize exposure to dust, spores and gases.
Personal Protective Equipment - Enter silos or manure pits only with air-supplied full face respirator.
Use a wet process when cleaning.
Use chemical cartridges for toxic organic vapours.
Dusts
Dust and mould spores are encountered in many agricultural activities, and are often associated with
respiratory illnesses, such as Farmers Lung, Toxic Organic Dust Syndrome, and Extrinsic Allergic
Alveolitis.
Engineering practices
The prevention of particle release and control of dust is achieved by providing leak proof ducts and
enclosed conveyor systems for grains and feeds. Buildings should have local ventilation systems in
areas frequented by workers where particulates become airborne. For field operations self-propelled
equipment should have enclosed cabs provided with filtered air. Where crushers, grinders and mixers
are used, the area should be enclosed to contain the airborne materials.
Work practices
There are several practices that can either help prevent the growth of mould spores or limit the damage
they can cause. The following measures are recommended:
Harvested crops such as hay and grains should be dry when stored (14% moisture content). Ventilate
areas where bales are being opened and wear respiratory protection when doing so.
