A worker was transferring a flammable liquid (RC-250) from a tank into his truck, but when he’d finished dispensing the fuel noticed the transfer line had become stuck because of the cold outdoor temperature. He decided to use a propane blow torch to unfreeze the line, but as soon as the torch was lit the vapours from the flammable liquid ignited and exploded. The worker died from burns he suffered during the explosion.
This horrible accident occurred in the USA, and it’s a real reminder of just how important it is to make sure staff fully understand the chemical properties of any flammable liquids and Dangerous Goods they are handling. Staff training is an essential requirement of AS1940:2017 - The storage and handling of flammable and combustible liquids and this blog discusses the type of training you need to deliver to staff, contractors and other personnel who may encounter flammable and combustible liquids at your worksite.
Training employees and site personnel
All staff working with flammable liquids must receive formal training so they understand the risks and hazards to their safety while working with these chemicals. Because flammable and combustible liquids are found on just about every workplace, they are often not treated with the full respect they deserve — many accidents (like the man using a blowtorch on a fuel transfer line) occur because workers don’t fully understand the flashpoint of the flammable liquids they are using.
The content of the training delivered to your employees and site personnel will depend on the duties they are performing; whether they are directly handling Class 3 Flammable Liquids; or just working in areas where flammables are stored.
At the very least your staff need to know how to identify the liquids held onsite and their chemical properties using the applicable Safety Data Sheets (SDSs). Training content would also include:
- Relevant safety regulations (personal responsibilities, controlling ignition sources, restricted areas, site housekeeping, and upkeep)
- Safe handling procedures (preparing a work area, earthing and bonding, liquid dispensing, spill response, and waste removal)
- Chemical properties of the flammable liquids (flash points and explosion limits)
- First aid procedures (location of first aid stations, first aid measures including how to use safety showers and eyewash facilities)
- Mandatory PPE (where it is stored, how to use it, how to keep it clean and properly maintained)
- Emergency procedures (emergency venting, shut-offs, fire and explosion responses, location of the manifest of hazardous chemicals)
- Evacuation drills and other simulated emergency exercises
IMPORTANT: The list above identifies some of the training requirements under AS1940:2017 - The storage and handling of flammable and combustible liquids, but always conduct your own risk assessment to determine the training required to ensure your staff can safely handle flammable liquids as well as respond to an emergency.
The Standard requires that all contractors and their staff must receive training appropriate to the work they are carrying out onsite and the areas they will be accessing. This safety and induction training must include:
1. Safety rules of the site
Safety rules that apply to everyone onsite (eg, non-smoking areas, restricted access points, ignition controls, speed limits) as well as rules specific to the tasks being performed by the contractors (eg, low voltage tools, visitor registration, protective clothing).
2. Conditions and obligations of work permits
If any work permits are in place (eg, confined space entry), contractors must be aware of the full conditions of the permit and their personal responsibilities and obligations.
3. Site hazards
Hazards likely to be encountered on the site — not just Class 3 Flammable Liquids but any hazardous chemicals or dangerous goods that may affect their health and safety.
4. Emergency procedures
Everyone on-site needs to know what to do in an emergency (fires, explosions, spills, natural disasters), this includes site contractors and their staff. The training would include the location of first aid stations, how to activate safety showers and eyewash facilities, emergency PPE (breathing apparatus, face masks), fire protection equipment, muster points, and evacuation areas.
REMEMBER: Training for contractors need only relate to the actual tasks they will be performing while on-site. For example, a delivery driver transferring fuel from their truck to a bulk tank might be notified of hazards like gas cylinder stores and other Dangerous Goods held onsite, but may not need to know the rules and layout of the packaging warehouse.
Refresher training for staff and contractors
Refresher training is an essential requirement of the Standard to ensure that staff and contractors maintain competence in safety procedures. Job sites change, new chemicals are introduced, flammable liquids are bought from different suppliers, and flammable storage cabinets are updated as new technologies emerge: it is not enough to deliver a 30-minute safety induction and then expect duties will be carried out perfectly for the next 5 years.
Additionally, refresher training should occur whenever:
- Workers or contractors are observed not following appropriate safety procedures
- An accident or dangerous incident occurs
- Workers have spent significant time away from their normal duties (long service leave, sickness, site transfer)
- Changes are made to operating procedures or new flammable liquids are introduced to the site
IMPORTANT: You must keep permanent records of staff training including refresher sessions and updates, as well as the details of emergency and evacuation drills. These records will also help you to schedule refresher training.
