Safety Handling dangerous goods
The WA Government’s Department of Mines and Petroleum has put together some handy tips on the safe storage and handling of dangerous goods on farms
Dangerous goods are substances with properties that can be hazardous to safety or health if not stored and handled safely. Most farms use some form of dangerous goods either to operate machinery (fuel, oil) or control weeds and pests (fumigants).
HOW CAN I RECOGNISE DANGEROUS GOODS?
These goods can be recognised from the marking and labelling with the presence of a class diamond and a United Nations (UN) number on the packaging. The class diamond indicates which acute inherent hazard the item has. On receiving a delivery of dangerous goods, check that the packages are in sound condition and are labelled correctly. If the packaging or labelling is defective, contact the supplier to rectify.
WHAT DO I NEED TO CONSIDER WHEN STORING? Segregate
A number of dangerous goods can react dangerously when mixed, and have the potential to start a fire or release toxic gases. Be safe and store these goods apart (Table 1).
Security measures need to be in place to prevent unauthorised access to dangerous goods. This is particularly important for highly toxic dangerous goods such as 1080 baits and aluminium phosphide pesticides, as well as other herbicides and pesticides.
Protect storage areas from impact
On a farm, there is usually enough space to place dangerous goods storage facilities (such as a shed) out of harm’s way. However, this is sometimes not practical – for example, if there is a fuel dispenser on, or adjacent to, an above-ground fuel tank.
In these situations, you need to protect the tank and/or dispenser from vehicle impact. You can do this by installing bollards (concrete-filled steel pipes) or placing clean 200-litre or 110-litre drums filled with concrete or sand around the area.
Underground tank storage or handling systems
Though uncommon, some properties have underground fuel storage tanks. These tanks need to be designed, installed, operated and maintained so that they do not leak. Guidance is available in Australian Standard AS 4897 on how to store fuel in underground tanks safely (www.dmp.wa.gov.au).
HOW DO I HANDLE DANGEROUS GOODS SAFELY? Ignition sources
When handling flammable liquids such as petrol, or flammable gases such as LP or acetylene gas, ignition sources need to be kept away. These sources include naked flames, mobile phones, or activities such as smoking, welding, cutting and grinding.
Safety information and equipment
Material safety data sheets (MSDSs), also known as safety data sheets (SDSs), are good sources of safety and health information for the dangerous goods you have. You should have all the MSDSs for the dangerous goods stored and handled at the farm readily accessible in case of spills, poisoning or emergencies.
MSDSs are available from the supplier or manufacturer of dangerous goods, or can be found on the internet. These sheets also provide guidance on the types of personal protective equipment (PPE) that should be used when handling certain dangerous goods. This equipment should be kept and maintained ‘fit for purpose’. In particular, check that respirator cartridges are rated to the type of chemical being used.
Workers and supervisors
Induction, information, training and supervision need to be provided to those who work with dangerous goods. There should be safe systems of work and work practices that enable people to do their job safely. Relevant training needs to be considered for: • Workers who carry out specific tasks, i.e handling herbicides • Managers and supervisors who should have training relevant to the dangerous goods in areas they supervise.
This may be provided in-house or take the form of in-services by agricultural industry trainers or chemical suppliers, including providing MSDSs and proper use of PPE and safety equipment.
DISPOSAL Clean up spills or leaks
Dangerous goods stored on the farm sometimes spill or leak. Make sure that the spill or leak is cleaned up as soon as possible using a spill kit. Check that you have a spill kit handy. The kit could include a bucket of clean dry sand, ‘kitty litter’, clean empty containers with lids or caps for spill recovery, broom, and shovel.
Empty dangerous goods containers such as plastic drums need to be made safe through industry recycling initiatives like AgSafe’s DrumMuster collection (drummuster.com.au), or containers properly disposed of. Re-use of dangerous goods containers should only happen after appropriate decontamination measures (such as scrubbing, rinsing and steam cleaning) have been taken to effectively remove chemical residue.
Keeping old or unwanted chemicals in your shed presents an unnecessary risk to people, animals and the environment. AgSafe’s ChemClear program is run periodically to assist in the disposal of unwanted chemicals.
DID YOU KNOW?
Farms can be defined as a rural dangerous goods location under the Dangerous Goods Safety (Storage and Handling of Non-explosives) Regulations 2007 and are required to meet safe storage and handling requirements.
