In the past couple of years there have been three serious incidents resulting from the ignition of diesel vapour in asphalt plants causing severe burns and fatalities among workers. WorkSafeBC approached the Construction Safety Network, representing the B.C. road building industry with a request to strike up a committee responsible for finding an alternative product to replace diesel as a cleaning agent in asphalt plants. This committee was made up of industry representatives and was facilitated by the Construction Safety Network.
Diesel fuel was being used as a both a degreaser and release agent in asphalt plants as this was an accepted industry practice; however Occupational Health and Safety Regulation 5.32 – Manual Cleaning states “A flammable liquid must not be used as a manual cleaning solvent unless a thorough review of alternative solvents by the employer indicates that a suitable non-flammable substitute is not available.
In recent years many new alternative products have flooded the market that claim to have the same effect as diesel. It was the committee’s responsibility to research the products and poll industry in order to show that alternative products are available and are similar in cost and as effective as diesel.
After April 30th, 2007, the practice of using diesel as a release agent or degreaser in asphalt plants will no longer be acceptable. WorkSafeBC will begin to encourage the use of alternative products and will eventually begin to inspect workplaces. If required they will write orders or may even recommend penalties for those companies still using diesel.
The Construction Safety Network would like to thank Industry committee members as well as those companies who shared information during the research phase for their time and valuable experience. Thank you also to WorkSafeBC for dedicating resources to this cause.
