Toluene
Toluene Chemical Overview
As an Aromatic in the Petrochemical family tree, Toluene Diisocyanates are classified as hazardous materials under the Department of Transportation’s Hazardous Materials Regulations. Thus, the unloading of tank trucks or rail cars must be done in strict accordance with those regulations. Toluene, also known as methylbenzene, is an organic chemical compound with the chemical formula of C7H8. Insoluble in water, Toluene is a colorless liquid with an odor similar to paint thinners. In commercial applications, toluene is a solvent found in paint thinners, nail polish remover, glues, and correction fluid. Toluene can even be found in the explosives industry, where it is essential in making the flammable, explosive compound known as TNT or trinitrotoluene.
What is Toluene?
Toluene is an aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH₃) attached to a phenyl group. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent.
In the United States, Toluene is typically a “tight-fill” (closed-fill) loading operation and is loaded into rail cars via chemical hoses or 3” carbon steel loading arms. Toluene, if not handled properly can be fatal and Personal Protective Equipment (PPE) is required. Additionally, because operators are on top of the vehicles during the loading process, fall prevention is essential, not only for safety but increases throughput.
Although no two Toluene Loading solutions will be identical, the product itself determines much of the critical design criteria that will ensure that optimum safety and productivity can work together in harmony.
Toluene is typically shipped in insulated tank cars, equipped with external heating coils and a safety relief valve set for 75 psi. The temperature of the contents must be above 60 degrees F or (16 degrees C) when the car is unloaded. If needed the tank car can be heated to 68 degrees, but do not exceed 104 degrees F or 40 degrees C.
Toluene is a highly flammable liquid and it can cause mild damage to the skin and the eyes. However, the most-common hazard associated with this chemical is inhalation. Products containing toluene can produce dangerous fumes which can cause nausea, headaches, unconsciousness, and even death if inhaled.
Only properly trained and equipped personnel should be permitted to unload tank trucks. Operators should wear an approved respiratory protective device, and impervious clothing, footwear, gloves, and goggles.

Solutions
Below are some of the loading and unloading solutions for illustrative purposes only. Our experts will work with you and your team for a custom solution to suit your needs.
Loading Gangways & Safety Cages
Wide access gangways (48″-60″) are preferable to allow safe access and egress to and from the vessel. In addition, a wider gangway reduces the risk of PPE getting caught, torn or damaged, while improving productivity and safety. Powered gangway solutions allow for hydraulic and pneumatic use, reducing stress and strain on operators.
Each gangway is fitted with a two-rail safety cage for the railcar crash box or a four-rail safety cage for access trucks.
Loading Arms
Chemicals are typically loaded into railcars or tank trucks via boom-supported 316 stainless steel loading arms or chemical hoses with a flange connection. The arm or hose uses a top inlet with a control valve to ensure that it is self-draining after use and is supported along the length of a mechanical loading arm (by-pass arm) to improve handling. When required, a vapor hose can be mounted on one by-pass arm.
When unloading, use of a rigid 316 stainless steel arm with EPDM or PTFE seals or a braided stainless steel chemical hose is typical. Purge lines can be fitted to the arm for nitrogen purging. Additional features such as parking latches with proximity sensors can be incorporated into the total system to ensure the arm is correctly stowed when not in use to prevent rail movement.
Eye Wash/Drench Showers
ANSI guidelines state that an Eye Wash/Drench Showers need to be located 10 seconds or 55’ (16.8m) from contaminants or hazardous materials.
Eyewash stations need to be on the same horizontal plane with no obstructions.
Therefore, we propose installing a standard combination Drench Shower/Eyewash Unit, which will save limited space and fit easily into any work environment.
Spill Containment
Spill containment, such as railcar track pans will be provided at the point of loading operations and are an essential piece of equipment in overall site safety and environmental protection.
Wheel chocks allow for safe access to and storage of treatment chemicals, while spill containment pans utilized at the point of loading operations serve as essential safety and environmental protection tools.
Piperacks
Because chemical plants have pipe runs throughout the facility, ErectaRack pipe racks are pre-fabricated for a variety of pipe dimensions and applications. Because they’re pre-engineered, ErectaRack skips the long engineering and fabrication process, saving weeks, if not months in the installation process.
Grounding
Proper grounding is essential when loading and unloading chemicals to prevent static electricity buildup, which can cause sparks and lead to fire or explosion hazards. SafeRack offers grounding systems designed to ensure a secure connection between the transport vehicle and the facility, meeting industry safety standards while protecting personnel and equipment.

North America’s largest loading terminal
As one of the primary railcar loading points, Hardisty is one of the major crude oil hubs in North America and a major origination point of pipelines that export to the United States. SCS was asked to supply and construct a SafeRack crude oil loadout terminal spanning nearly half a mile. The USD Hardisty terminal can load up to two 120-railcar unit trains per day and consists of a fixed loading rack with 62 railcar loading positions enclosed, separate control, operator, and mechanical buildings, as well as a unit train staging area and loop tracks capable of holding multiple unit trains simultaneously. SCS also supplied and installed boom-supported loading arms with supply and vapor management systems.
Why SafeRack?
The SafeRack approach is collaborative. Let’s call it The SafeRack Way. Over many years, we have amassed a great deal of experience and understanding of the safety aspects involved in loading road tankers and railcars, as well as the behavioral habits of the operators.

Petrochemicals are made from either petroleum or natural gas feedstock. A wide variety of petrochemicals are created/produced depending on the process.
Synthesis gas (SynGas) – A mixture comprising of carbon monoxide, carbon dioxide, and hydrogen. Common Synthesis Gas is Ammonia and Methanol. Often used for creating Fertilizers and explosives. Synthesis gas is a mixture of carbon monoxide and hydrogen used to make ammonia and methanol. Ammonia is used to make the fertilizer urea, and methanol is used as a solvent and chemical intermediate. Steam crackers are not to be confused with steam reforming plants used to produce hydrogen and ammonia.
Aromatics – Aromatics are hydrocarbons that consist exclusively of the elements carbon and hydrogen. Common Aromatics are Benzene, Toluene, and Xylenes. Often used for creating Dyes, synthetic detergents, fibers, and plastics.The catalytic reforming of naphtha produces aromatics, which include benzene, toluene, and xylene. Together they are referred to as BTX and are predominantly obtained from petroleum refineries by the extraction from the reformate produced in catalytic reformers using naphtha obtained from petroleum refineries.
Olefins – The most reactive class of hydrocarbons tend to crack. Common Olefins are Ethylene, Propylene, and Butadiene. Often used for creating plastics, and synthetic rubber. Chemical plants produce olefins by steam cracking of natural gas liquids like ethane and propane. Olefins include ethene, propene, and butadiene. Ethylene and propylene are chief sources of both plastic products and industrial chemicals. Butadiene is mainly used in the production of synthetic rubber.
