1. Safety
Working at Heights
Whilst the equipment has been designed to operate primarily at ground level, at some stages during the life cycle it will be necessary to operate at heights. For this reason the equipment has been provided with access ladders, platforms and walkways. These have been designed to recognized safety standards to minimize the risk to health and safety to operators and technicians working on them. In addition attention should be paid to the following safety requirements.
1. The ladders, platforms and walkways are for use by competent and trained personnel only. NEVER allow children or members of the general public to gain access to the equipment, its ladders or access platforms.
2. Where the equipment is sited in an unsecured location, access must be restricted by use of security fencing and lockable gates.
3. Lower sections of ladders on the equipment should be fitted with a lockable safety gate, to prevent unauthorized access.
4. Ensure any hot surfaces have had adequate time to cool before working on or in the equipment. This may require running the equipment fans only to cool off external screens and internal burner components.
5. The equipment should be OFF and all power LOCKED OFF before work on or in the equipment. Ensure the power isolator is OFF and LOCKED and TAGGED to prevent inadvertent re-start. This must include all equipment attached to the dryer/bin on which you are working. (See Figure 1A.)
Figure 1A
6. Ensure the fuel supply is OFF and LOCKED. (See Figure 1B.)
Figure 1B
1. Safety
7. NEVER attach lifting equipment to ladders or platforms.
8. When working on the equipment, NEVER go outside the safety rails provided.
9. NEVER walk on the roof of the equipment.
10. Do not work at heights during high winds, heavy rain, snow, ice or storm.
The majority of routine cleaning and service can be carried out from the service platforms provided. However in exceptional circumstances it may be necessary to access other parts of the equipment. In particular, in the rare event that access is required to repair or r eplace the g rain level switches. On th ese occasions additional access and safety equipment may be required. Wherever possible we recommend the use of powered access lift platforms or ‘cherry pickers’. In exceptional circumstances access may require the use of safety harness. Such work must only be carried out b y specialist technicians trained and qualified in working at heights and only after a complete risk assessment has been carried out and safe working methods established.
Entering Grain Dryers
Wherever possible it is recommended not to enter grain dryers. However, if you have to enter the, observe the following minimum
precautions:
1. NEVER
2. Make sure you are aware of all the possible hazards
3. Complete a risk assessment
4. You may need to complete a permit to work approved by the dryer owner or supervisor.
5. Ensure the dryer has been purged of any products of combustion. Shut off the burner but leave the fans running for at least 30 minutes before entry.
6. Do not smoke or use naked flames in or around the dryer.
7. Where there is a risk of harmful gases or vapors, check the atmosphere with a suitable analyzer. If necessary, run the fans for longer to provide a safe breathable atmosphere. If in doubt do not enter
8. Switch OFF, lock and tag equipment feeding and emptying the dryer. This will require turning the main power isolator to OFF, LOCKING it and apply a TAG to prevent inadvertent re-start. (See Figure 1C on Page 11.)

1. Safety
WARNING
Keep the dryer clean. Do not allow fine material to accumulate in the plenum chamber or surrounding the outside of the dryer.
Precautions to Reduce Risk of Fire
Whilst the dryer has been designed to minimize the risk of ignition of combustible dust and dirt, this can only be ensured by regular inspection and cleaning. At least every five (5) days.
1. Refer to Page 10 for required precautions before entering the dryer. The dryer must be locked out and tagged at the main power and fuel supply before entering.
2. Open the dryer access hatches and check for any significant build-up of dust or particles of grain.
3. Using an industrial vacuum cleaner, clean the plenum. Do not use compressed air.
4. Check inside other dryer accesses and clean as required.
5. Check all personnel are out of the dryer, close and lock all accesses before re-starting drying.
6. This procedure may be carried out more regularly in conditions of extreme dust and dirt.
Exercise greater caution when drying highly flammable grains and seeds. For example rapeseed, can ola, linseed, sunflower and milo.
All grain and seed must be whole (minimal cracked or crushed), clean and dust free. Dry at low temperatures (< 40°C). Avoid dust and chaff being drawn into the fan and heater. Keep the fan, heater, drying plenum and ducts clean at all times. In the event of a fire (or suspected fire).
• Shut down the entire dryer.
• Turn OFF fuel at the tank or supply valve.
• Shut off and lock electrical power.
• Evacuate the area.
• Call the fire department.
Use Caution in the Operation of this Equipment
This dryer is designed and manufactured with operator safety in mind. However, the very nature of a grain dryer having a gas burner, high voltage electrical equipment and high speed rotating parts, presents hazards to personnel which cannot be completely safeguarded against withou t interfering with the efficient operation of the dryer and reasonable access to its components.
Use extreme caution at all times when working on or around the dryer.
Continued safe, dependable operation of automatic equipment depends, to a great degree, upon the owner. Follow the recommendations within the Owner’s Manual and make it a practice to regularly inspect the unit for any developing problems or unsafe conditions.
Take special note of the safety precautions on Page 8 before attempting to operate the dryer.
