Methyl Chloride Loading Solutions – Optimal Safety for Maximum Productivity
What is methyl chloride?
Chloromethane, also referred to as methyl chloride, is a colorless, odorless, and extremely flammable liquefied gas. CH3CI is a crucial reagent in industrial chemistry, commonly used in the manufacturing of paint removal technology, pharmaceutical manufacturing, and metal cleaning and degreasing.
In the United States, methyl chloride is a “tight-fill” (closed-loop) operation via chemical hoses or 3” stainless steel loading arms to load and unload into rail cars or trucks. If not handled properly, methyl chloride can cause serious injuries which is why the use of personal protective equipment (PPE) is required. Because loading operators need to access equipment from the top of the vehicles while operating, high-quality fall prevention systems are essential to ensure increased throughput and operator safety.
Methyl chloride is typically shipped in 26,000 gallon DOT-105, 112 or 114 pressurized insulated or non-insulated tank cars with safety valves. The rails cars themselves are ~ 9′ outside diameter with an overall length of ~45’ to 50′, with a 6’ x 6’ center opening or off-set crash box openings.

Tank truck loading and unloading procedures are similar to railcar applications with the trailers meeting established DOT requirements for transporting methyl chloride and other similar commodities. Approved DOT trailers include MC 307 or low pressure chemical ISO containers. Trailers and ISOs are typically unloaded from the bottom. 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.
Specifications for Your Project
As a starting point, we will need to know the following:
- Railcar connection locations require 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 will you spot your railcars?
Our highly trained technical sales team will complete a detailed site survey to determine all dimensions, obstructions, and access issues. Our goal is always to provide the safest working environment to protect operators and the equipment while helping you improve throughput and productivity at your facility.
Whether you are looking for a turn-key installation, on-site supervision or a safety maintenance program, we are ready to assist you. We can do as little or as much as you need. Our project management and supervision team are the best in the business ready to support the needs of your company.
- Collaborative Design – Our loading platform specialists will work with you one-on-one to design the best loading solution for your facility.
- Contract Review – Our team will review the drawings and associated documents related to the contract prior to site arrival.
- Risk Assessment – We will always provide a thorough review of your site to assess the risks to workers and visitors to your facility.
- Shipment Inspection – Each shipment is thoroughly inspected for shipping damage or abnormalities.
- Material Receiving – Our team will supervise off-loading and transport at your site.
- Installation Management – We offer supervised installation and on-site coordination of your project.
- Start-up & Commissioning – On-site training is available as needed for users and maintenance personnel.
Generally speaking, we recommend rigid pipe loading arms wherever possible. We believe they are the most successful option because they are:
- balanced throughout their movement envelope
- designed not to hit the ground, protecting the asset and the operator
- ergonomic requiring only one person operation
- fitted with manual or actuated valves
- fitted with optional purge/vent facilities
- moved into position with ease and left hanging in the air while the operator prepares the tanker connection
- parked neatly
Alternatively, we don’t recommend hoses because they:
- require an annual pressure test
- are difficult to stow neatly when not in use
- can be dropped or 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 them
- 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.
Methyl Chloride Loading
Methyl chloride is typically loaded into railcars or tank trucks via boom-supported stainless steel arms or chemical hoses with flanged end connections. The arm or hose will have a top inlet with a control valve to ensure it self-drains after use and is supported by a by-pass arm along the length of a mechanical loading arm to improve handling. One liquid and one vapor arm can be installed both the liquid and vapor hoses can be mounted on one by-pass arm.
For unloading, typically a rigid stainless steel self-draining loading arm with PTFE or Viton seals would be used. 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.
Loading Gangways & Safety Cages
A 36″-48″ wide access gangway is preferable as it helps improve access and egress to and from the vessel. 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’ safety cage to sit directly over the crash box. This will provide a safe, secure work environment for operators connected to a breathing apparatus.
GX SELF-ADJUSTING STAIR (SAS) GANGWAY
GX SAS gangways use Retractalok power-assist technology allowing operators to raise or lower effortlessly. Tested in the most critical applications, this revolutionary new gangway is light as a feather and solid as a rock, outperforming all others in the marketplace. Available in multiple lengths and widths. Learn More
Methyl Chloride Eye Wash/Drench Showers
ANSI guidelines state that eyewash/drench showers need to be located 10 seconds or 55’ (16.8m) from contaminants or hazardous materials.
Eyewash stations must be on the same horizontal plane with no obstructions.
Our standard combination drench shower/eyewash unit saves limited space and fits easily into any work environment.
Methyl Chloride Spill Containment
Spill containment pans are provided at the point of loading operations and are an essential element of a comprehensive site safety and environmental protection plan.
Methyl Chloride Grounding
Methyl chloride is a flammable liquid and vapor. Industry best practice includes the grounding of all vessels before starting the loading or unloading process.
- Ground controllers — ensure true grounding before product flow is permitted.
- Explosion-proof enclosures — meet or exceed UL, CSA, and Ex requirements.
- Always use non-sparking tools when handling MMA.
Methyl Chloride Safety Gates
Safety Gates will be installed at the top of stairs and any other openings to ensure operator and visitor safety at all times.
YellowGate Safety Gates
Our industrial safety gates are the most flexible fall protection product on the market with openings spanning 16” to 36”. Field adjustable with nothing more than a wrench, they are an easy way to protect every opening with just one SKU. Learn More
Methyl Chloride Options
- Lighting – Lighting both over and under the platform will be provided for optimal safety. For overcast days or second shifts, lighting is essential for improved safety and productivity.
- Platform & Canopies – Full platform canopies reduce exposure to the elements and improve safety and productivity from the loading operator’s perspective.
- Operator Shelter – Depending on your site requirements, consideration should be given to an operator or guard building on the loading platform. This can be customized to meet specific site requirements.
- Wheel Chocks – 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. This is a requirement by the Department of Homeland Security.
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 are suggested in some operations. Wear a chemical protective, full-body encapsulating suit, and self-contained breathing apparatus (SCBA). 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. The following materials should NOT be used: natural rubber, polyvinyl chloride. Recommendations are NOT valid for very 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.
Use a local exhaust ventilation and enclosure, if necessary, to control the amount of vapor 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 (e.g. double mechanical pump seals) to prevent the release of this material due to equipment failure. * For illustrative purposes only.

SUCCESSFUL METHYL CHLORIDE LOADING PROJECTS COMPLETED
Methyl Chloride 101
Things to know about Methyl Chloride
Methyl Chloride is regulated by the U.S. Department of Transportation (DOT) and is classified as a flammable, liquefied gas with the DOT identification number UN 1063.
Methyl chloride is used as a chemical intermediate in the production of silicone polymers. It is also used as a solvent in the manufacture of butyl rubber and in petroleum refining.
Only properly trained and equipped personnel should be permitted to load or unload methyl chloride tank cars and tank trucks. Operators should wear approved PPE equipment including impervious clothing, footwear, gloves, goggles, and a respirator.
Methyl chloride is dangerous to human health, as acute exposure can cause severe cold skin burns and possible frostbite. Use only outdoors, or in a well-ventilated area.
Methyl chloride kills by turning into carbon monoxide upon entering the body. Once inside, the chemical replaces oxygen in the blood and quickly starves the heart and brain of air. Fatal injuries can occur in as little as 5 minutes. Since 2017 the EPA has restricted the use of this toxic chemical used in paint and coating strippers due to accidental deaths.
First-aid measures for exposure include:
- Remove operators from the source of exposure and into the fresh air.
- Remove contaminated clothing immediately.
- Wash skin thoroughly with soap and water.
- Flush eyes with tepid water for 15 minutes.
Store away from oxidizing agents, strong acids, or bases. Store in a cool, dry environment not to exceed 125 degrees F (52C) Post “No Smoking/No Open Flame” signs in storage and use areas.
Methyl chloride is not compatible with aluminum, carbon, or milled steel so great care should be taken to avoid contact with these materials. However, galvanized, stainless, and powder-coated steel are viable options.

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.
