Safety is a three-step process - identify hazards, assess risk and address the hazard... Most lids still require a climb to the top of the silo to inspect rubber seals and latch the lid before the silo will meet a half-life pressure test, required for effective fumigation... Safe and sound on the ground: Ground-operated lids reduce the number of times a silo has to be climbed, but most situations require a climb to secure the lid for effective fumigation...

With the winter harvest mostly put away, the Grains Research and Development Corporation (GRDC) is encouraging farmers considering fumigating grain stored on farm to do it wisely and carefully... The GRDC says there are several key points when you are looking to fumigate stored grain, including effectiveness and safety... Farmers may think a silo is sealed because it keeps out rain, or because it was originally purchased as a "sealed silo" but in reality even new sealable silos can have construction or design faults resulting in leaks...

The decision of which silo to buy can be daunting, mainly because it's a 20+ year investment and not a purchase that is easily returned or traded-in if it proves unsuitable... Choose carefully: While all silos are made to store grain and 'do the job', some will enable superior grain quality management than others... The main options are to have an WHS compliant ladder, use a safety harness or build a platform that spans along the top of a line of silos...

Pressure testing a silo ensures it can hold gas concentrations sufficient to kill all insects at all life stages... If the silo has a slide plate outlet that has been tested empty, retest when full to make sure the pressure of the grain doesn't compromise the seal... Common places for leaks are: bottom outlet, aeration inlet seal, damaged lids (caused by the auger when lining it up to fill the silo), stretched springs on latches, between the bottom cone or base and the silo wall joint, the roof and wall joint and where the lid ring joins the roof...

Choose carefully: While all silos are made to store grain and 'do the job', some will enable superior grain quality management than others... In order to meet a ve-minute half-life pressure test, the silo must have: a pressure (oil) relief valve large enough to suit the silo and with gauge markings system to add air to perform a pressure test rubber seals made of high-density EPDM (ethylene-propylene-diene-monomer) rubber with a strong memory and UV resistance...

Northern growers storing winter crop on farm can ensure reliable grain quality by focusing on best hygiene practice, monitoring and cooling... "In terms of temperature, aim to keep grain less than 22 C through summer to slow storage pest activity, and when grain first goes in, ensure that aeration fans are run continuously for the first 2-3 days to push the first cooling front through and create uniform moisture... "An aeration controller will perform the cooling process at the right time, aerate the grain with the coolest air and ensure fans don't operate when the relative humidity is higher than 85 per cent, which can re-wet and damage grain if operated for extended periods."..

Standard to seal off phosphine resistance.. A new national standard for gas-tight grain storage aims to 'knock down' the phosphine resistance in grain insects that has been gnawing at the industry since a pest beetle strain was first detected on a Queensland farm 13 years ago... Many grain silos have failed to meet the gas-tight standards required for effective fumigation, creating a serious threat to the Australian grains industry by increasing target insect pest resistance to phosphine treatments," Mr Botta says.

Paul Kamel (left) and Les Zeller on-site at Tammin, WA, with the telemetry equipment installed to relay data on phosphine concentrations directly to a central database... The step would have removed the need for data from the phosphine monitors to be gathered and recorded manually... The automated phosphine monitoring system is designed to gather information including temperature, humidity and the concentration of phosphine being recirculated and also references this data with the silo being recirculated...
