Although no two Sodium Cyanide 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.
What is Sodium Cyanide? Sodium cyanide, also known as Hydrocyanic acid, sodium salt or cyanide of sodium is a poisonous compound with the formula NaCN. It’s a white, water soluble solid or powder with a bitter almond-like odor. NaCN is produced by treating hydrogen cyanide with sodium hydroxide. Sodium cyanide is used commercially for fumigation, electroplating, extracting gold and silver from ores, and chemical manufacturing.
In the United States, Aqueous Sodium Cyanide is a “tight-fill” (closed-loop) loading operation and is loaded or unloaded into rail cars via chemical hoses or PTFE lined loading arms. Sodium cyanide, 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, robust, well-designed fall prevention is essential to ensure increased throughput, without compromising operator safety.
Sodium Cyanide is typically shipped in 26,000 gallon DOT-111 insulated or non-insulated tank cars with safety valves. The rails cars themselves are ~ 9′ outside diameter with an overall length of ~45’ to 55′, with a 6’ x 6’ center opening or off-set crash box openings.

Tank truck (un)loading procedures are similar to railcar applications with the trailers meeting established DOT requirements for transporting sodium cyanide or other similar commodities. Approved DOT trailers include MC 307 or low pressure chemical ISO containers. Trailers and ISO’s are typically bottom unloaded. An extension pipe with two valves is flanged to the top of the trailer.
All trailers must be equipped with pressure relief valves, and trailers with bottom outlets must be equipped with remote controlled stop valves.
Typically, as a starting point, we will need to know answers to these questions for your project
- The Railcar connection locations need flexibility – Do you know what the breadbasket connections look like?
- Are you using liquid and vapor arms/hose as two separate devices or a piggyback arm?
- Is the loading station indoors or outdoors?
- Is the loading area temperature controlled?
- How are you going to spot your railcars
Our highly trained technical sales team will undertake a detailed site survey prior to undertaking any work to check and clarify all dimensions, obstructions, access issues and other salient points. Our challenge is to provide the safest working environment – protecting operators and the equipment – while simultaneously enabling you to improve throughput and productivity.

- Can be dropped
- Can be driven over
- Are very heavy to use if fitted with a valve at the tanker connection point
- Cannot be easily heated or have vent/purge valves fitted to it
- Prone to catastrophic failure

Start by selecting loading application
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.
Sodium Cyanide Loading Arms
Sodium cyanide is typically loaded into railcars or tank trucks via boom supported PTFE lined loading arms or chemical hoses with a flange connection. The arm or hose will have 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 to improve handling; this is known as a by-pass arm. You can install one liquid and one vapor arm, or mount both the liquid and vapor hoses on one by-pass arm.
For unloading, typically you would use a rigid self-draining PTFE lined arm with Buna N (Nitrile), EPDM, Fluorocarbon (FKM), PTFE or Viton seals or a braided 316 stainless steel chemical hose. 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, before any rail movement can occur.
Note: Carbon Steel and Stainless steel materials of construction are rated “B” with a chemical effect resulting in slight corrosion and/or discoloration.
Loading Gangways and Safety Cages
A wider access gangway (48″-60″ is preferable) as it helps improve access and egress to and from the vessel. In addition, a wider gangway will reduce the risk of the operator’s PPE getting caught, torn or damaged, and will improve productivity and safety. Powered gangway solutions are also an option, with both hydraulic and pneumatic solutions being commonly used.
Each gangway will be fitted with a two-rail safety cage for the railcar crash box. This will be a centered 6’x6’ or 7’x8’ safety cage to sit directly over the cashbox. This will provide a safe, secure work environment for your operator when connected to their breathing apparatus.
GX SELF-ADJUSTING STAIR (SAS) GANGWAY
SafeRack’s NEW GX SAS gangways are light as a feather to lift and solid as a rock. Retractalok power-assist technology allows operators to raise and lower effortlessly. Tested in the most critical applications, this revolutionary gangway outperforms others on the market. Available in multiple lengths and widths. Learn More
Sodium Cyanide 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 would propose the installation of a standard combination Drench Shower/Eyewash Unit, which will save limited space and fit easily into any work environment.
Sodium Cyanide Spill Containment
Spill containment pans are essential in the overall safety of the facility and its workers and the protection of the environment.
Sodium Cyanide Grounding
Sodium cyanide is not flammable; however industry best practice includes the grounding of all vessels before starting the (un)loading process.
- Ground controllers — ensure true grounding before product flow is permitted
- Explosion-proof enclosures — meet or exceed UL, CSA and Ex requirements
- Non-sparking tools are also recommended while working around this product
Sodium Cyanide Safety Gates
Safety gates are installed at the top of stairs and to protect openings to ensure operator and visitor safety at all times.
YellowGate Safety Gates
Our industrial safety gates are the most flexible on the market. With the ability to span openings between 16″ and 36″, they are field adjustable and can be modified using nothing more than a wrench. Learn More
Sodium Cyanide Options
- Lighting – For overcast days or second shifts, lighting is essential for improved safety and improved productivity on and around the loading platform.
- Platform & Canopies – Full platform canopies reduce exposure to the elements and improve safe and productive loading operations.
- Operator Shelter – Site requirements may call for an operator or guard building on the loading platform. This can be customized to meet site specifications.
- Wheel Chocks – Required by the Department of Homeland Security, railcar wheel chocks provide fast blocking of all types of railcars and meet OSHA regulations to safely prevent railroad cars from moving during loading or unloading operations.
Personal Protective Equipment PPE Requirements
Eye/Face Protection: Wear chemical safety goggles. A face shield (with safety goggles) may also be necessary.
Skin Protection: Wear chemical protective clothing including gloves, aprons, and boots. Coveralls or long sleeve shirts and pants may be advisable in some operations. A chemical protective, full-body encapsulating suit and self-contained breathing apparatus (SCBA) may also be required. Suitable materials include butyl rubber, neoprene rubber, Viton®, Viton®/butyl rubber, Barrier® – PE/PA/PE, Silver Shield® – PE/EVAL/PE, Trellchem® HPS, Trellchem® VPS, Saranex®™, Tychem® BR/LV, Tychem® Responder® CSM, Tychem® TK. Recommendations are NOT valid for thin neoprene rubber gloves (0.3 mm or less).
Respiratory Protection: Up to 5 ppm:
(APF = 10) Any chemical cartridge respirator with cartridge(s) providing protection against chlorine*; or any supplied-air respirator*.
*Reported to cause eye irritation or damage; may require eye protection.
APF = Assigned Protection Factor
Recommendations apply only to National Institute for Occupational Safety and Health (NIOSH) approved respirators. Refer to the NIOSH pocket guide to chemical hazards for more information.
If necessary, use local exhaust ventilation and enclosure to control the amount of acetic acid in the air. Consider using a corrosion-resistant exhaust ventilation system separate from other ventilation systems. It may be necessary to use stringent control measures such as process enclosure to prevent product release into the workplace. Use backup controls such as double mechanical pump seals to prevent the release of this material due to equipment failure.

SUCCESSFUL SODIUM CYANIDE LOADING PROJECTS
Sodium Cyanide 101
Things to know about Sodium Cyanide
Sodium cyanide is regulated by the U.S. Department of Transportation (DOT) and is classified as a poison with the DOT identification number UN 3414.
Sodium cyanide was initially registered as a pesticide in 1947 to control ants, certain bacteria, insects and rodents in residential and commercial areas. It was later cancelled by the Environmental Protection Agency (EPA) in 1987 because of its extreme toxicity and is now restricted to use by only trained applicators.
Operators should wear approved PPE equipment including impervious clothing footwear, gloves, tight fitting goggles and a respirator when handling this chemical.
Sodium cyanide may be fatal if inhaled, absorbed through the skin or swallowed. Do not breathe dust, fumes, gas, mist or vapors. After exposure, cyanide is quickly absorbed into the bloodstream replacing oxygen in the cells resulting in the cells dying. The heart, respiratory and central nervous system are most susceptible to cyanide poisoning.
First aid measures for exposure include – removing operators from the source of exposure and into fresh air. Remove contaminated clothing immediately; wash skin thoroughly with soap and water; flush eyes with tepid water for 15 minutes.
If ingested, get medical help immediately. Only induce vomiting if directed to do so by medical personnel. Always have a cyanide antidote kit on hand when working with cyanide compounds.
Acids should not be used around sodium cyanide or potassium cyanide. Hydrogen cyanide (HCN) formation is the greatest potential hazard when handling sodium cyanide solutions because some HCN gases will be released.
Sodium cyanide is stable under normal temperatures and pressures. However it absorbs carbon dioxide and moisture from the air and deliquesces, meaning NaCN absorbs atmospheric water vapor and becomes a liquid.
Best practice includes storing in a locked, cool, dry, well-ventilated area away from incompatible substances, such as strong oxidizing agents and acids. Keep containers tightly closed and protected from moisture.
Sodium cyanide is not compatible with aluminum, brass or bronze. However, Galvanized and 304 stainless steel materials of construction, as well as, powder coating finishings are suitable with this chemical.

EMERGENCY EYEWASHES / SHOWER EQUIPMENT AND THE ANSI/ISEA Z358.1 – 2014 STANDARD
Following eye contact, you must start washing with water immediately to prevent permanent damage. In the event of skin contact, you must start washing with water immediately to prevent slow-healing chemical burns.
Are you aware that ANSI guidelines state that Eye Wash/Drench Showers need to be located 10 seconds or 55′ from contaminates or hazardous materials and located on the same horizontal plane, with no obstructions? If bottom loading/unloading, an additional shower should be located at grade as well. SafeRack provides the above equipment plus much more needed to keep employees safe and expedite bulk chemical loading and unloading.
