Guidelines for Secure Handling of Highly Inflammable Substances by Instructors and Overseeing Personnel
In the workplace, proper storage, handling, and disposal of flammable liquids are crucial to prevent fires, spills, and exposures. Adherence to recognized safety codes and training are essential in ensuring a safer environment.
Storage
Flammable liquids should be stored in containers specifically designed and approved for these substances, such as fire-rated containers. These containers are organized by their flammable class (I–III) to avoid incompatible mixtures. Maintain proper aisle widths and rack clearances to comply with NFPA 30 standards for fire protection. Use galvanized steel racks resistant to corrosion and implement secondary containment systems suitable for spill control, sized according to total volume stored and location. Keep storage areas well-ventilated and away from ignition sources like open flames, sparks, and non-rated electrical equipment. Ensure fire extinguishers are readily available, within 50 feet of the storage area if more than 5 gallons are stored.
Handling
Employees should be trained on hazard recognition, use of personal protective equipment (PPE) like flame-resistant clothing, gloves, goggles, and respirators, and emergency procedures related to spills or fire. Use grounding and bonding techniques when transferring flammable liquids to prevent static electricity accumulation that can ignite vapors. Conduct all handling in well-ventilated areas and keep flammable liquids away from ignition sources during use. Avoid spills by handling liquids carefully, employing proper containers, and following protocols in transfer to minimize exposure and fire risk.
Disposal
Dispose of flammable liquids and contaminated waste according to local hazardous waste regulations. Never pour flammable liquids down drains or into the environment. Use designated hazardous waste containers for collection and removal. Regularly remove combustible waste from work areas, storing it safely in metal receptacles and disposing of it daily to reduce fire hazards.
By following these guidelines, workplaces can minimize the risk of fire, explosion, and chemical exposure related to flammable liquids. Sparks and smoking must be avoided when handling flammable liquids. Spills or leftovers of flammable liquids become chemical hazardous waste. Never smoke around flammable liquids. Control all ignition sources around flammable liquids. Flammable liquids should be stored in a self-closing safety can. Storing gasoline requires a red container. Never store flammables in open or unapproved containers. Identify flammable liquid containers by a red diamond-shaped label with black lettering. Some materials can ignite from static sparks, so ground and bond all bulk containers during dispensing and pouring. Storing flammables must be done in a special storage cabinet that is well marked with warning signs for everyone to see. A fire extinguisher must be within 75 feet of all bulk transfer stations.
