Flammable liquids are common in many workplaces, from construction sites and maintenance shops to manufacturing facilities. But improper management of these materials can create serious safety risks. Understanding how to store, handle and label flammable liquid waste for disposal can help protect your workers, property, and business operations. Here are some best practices to help your business manage flammable liquid waste safely and support a safer workplace.
Storing and handling flammable liquid waste
Proper storage is an important first step in managing flammable liquid waste. Used or contaminated materials should generally be stored in approved, clearly labelled containers that are compatible with the substance being stored. If your workplace generates larger volumes of waste, your recycling or hazardous waste provider may be able to supply bulk collection containers.
Avoid mixing different hazardous or flammable liquids unless directed to do so by a qualified waste management provider. Keeping materials separate can simplify recycling and help prevent dangerous chemical reactions.
Depending on your location and industry, regulations may limit the amount of flammable liquid waste that can be stored onsite. Scheduling regular pickups can help reduce accumulation and support compliance with regulations. Keep in mind that some recyclers offer container services and regular pickup, depending on what and how much is being collected.
Make sure handlers wear the proper protective personal equipment (PPE) for all tasks related to handling hazardous or flammable liquids.
Labelling flammable liquids for disposal
Proper labelling helps workers identify hazards, handle materials safely, and respond appropriately in the event of an emergency. In Canada, flammable and hazardous workplace products are subject to the Workplace Hazardous Materials Information System (WHMIS).
The workplace label of waste materials should typically include:
- Product name
- An indication that the material is intended for recycling or disposal
- Safe handling instructions and hazard warnings
- A reference to the Safety Data Sheet (SDS) for additional information
Supporting safer hazardous waste management
Safe storage, handling and disposal are only part of an effective hazardous materials management program. Businesses can further reduce risk by minimizing the amount of flammable liquids used onsite, exploring less hazardous alternatives where appropriate, and providing employees with ongoing training on handling and storage procedures.
By combining best practices and employee education businesses can help reduce workplace hazards and build a stronger culture of safety.
Protect yourself and your business with insurance
By following the best practices above, you can significantly reduce the risks associated with flammable liquids and create a safer environment for everyone involved. However, accidents can and do happen. That’s where insurance can help. To learn more, visit our Construction & Contractors Insurance page today.
