Vinyl acetate loading solutions should be designed with optimal safety and efficiency standards in mind. Worker safety and productivity can work in harmony to ensure positive outcomes for your facility.
What is vinyl acetate?
Vinyl acetate is a clear colorless liquid, with a sweet, sharp odor used to make other chemicals, such as adhesives, paints, and plastics. It’s a highly flammable liquid and vapor and irritate the skin, eyes, and lungs.
In the United States, vinyl acetate is typically a “tight-fill” (closed-loop) loading operation with the product loaded into rail cars via chemical hoses or 3” stainless steel loading arms. If not handled properly, vinyl acetate can cause serious injuries and Personal Protective Equipment (PPE) is required. Additionally, because operators are on top of the vehicles during the loading process, excellent fall prevention systems are essential to ensure operator safety without compromising throughput.
Vinyl acetate 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 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 and trailers must meet established DOT requirements for transporting vinyl acetate. Approved DOT trailers include MC 307 or low-pressure chemical ISO containers. Trailers and ISO’s are typically bottom unloaded with a 2-valve extension pipe 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.

- Fitted with manual or actuated valves.
- Fitted with optional purge/vent facilities
- Can be moved into position with ease and left hanging in the air while the operator prepares the tanker connection
- Parked neatly
- Annual pressure test
- Are difficult to stow neatly when not in use
- 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.
Vinyl Acetate Loading Arms
Vinyl acetate is typically loaded into railcars or tank trucks via boom-supported stainless steel loading arms or chemical hoses with a flange connection. The arm or hose has a top inlet with a control valve to ensure that it is self-draining after use and is supported by a by-pass arm along the length of a mechanical loading arm to improve handling. This can be installed with one liquid and one vapor arm, or both the liquid and vapor hoses can be mounted on a single by-pass arm.
Typical unloading procedures call for a rigid stainless steel self-draining loading arm with Viton, PTFE, or EPDM seals. 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 wide 48 – 60″ access gangway is preferable, as it helps improve access and egress to and from the vessel. In addition, a wide gangway will reduce the risk of the operator’s PPE getting caught, torn, or damaged, improving productivity and safety. Hydraulic and pneumatic-powered gangway solutions improve ergonomics and provide ease of use for operators, even in a loss of power situation.
Gangways are fitted with a two-rail safety cage for the railcar crash box. Centered 6’x6’ or 7’x8’, the safety cage sits directly over the cashbox. This provides a safe, secure work environment for operators.
GX SELF-ADJUSTING STAIR (SAS) GANGWAY
SafeRack’s GX SAS gangways are solid as a rock and light as a feather to lift and lower. Retractalok power-assist technology reduces strain for operators and can drastically reduce repetitive strain injuries at your facility. Tested in the most critical applications, this revolutionary gangway outperforms all others. Available in multiple lengths and widths. Learn More
Vinyl Acetate Eye Wash/Drench Showers
ANSI guidelines state that an eyewash/drench shower needs 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.
Installation of a standard combination drench shower/eyewash unit can save space and fits easily into any work environment.
Vinyl Acetate Spill Containment
Spill containment pans are provided at the point of loading operations and are an essential component in overall site safety and environmental protection.
Vinyl Acetate Grounding
Vinyl acetate is a combustible 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
- Non-sparking tools are recommended while working around this flammable product.
Vinyl Acetate Safety Gates
Safety Gates are 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 versatile, with the ability to adjust to span openings between 16″ and 36″. YellowGate products are field adjustable and can be modified to fit with just a wrench. Learn More
Vinyl Acetate Custom Options
- Lighting – Lighting both over and under the platform can be provided. For overcast days or second shift, lighting is essential for improved safety and increased productivity.
- Platform & Canopies – Full platform canopies reduce exposure to the elements and improve safe and productive loading operations.
- Operator Shelter – An operator or guard building may be required on the loading platform. This can be customized to meet the specific site requirements at your facility.
- Wheel Chocks – Railcar wheel chocks provide fast blocking of all types of railcars and meet OSHA regulations for safety. Required by the Department of Homeland Security, they prevent railroad cars from moving during loading or unloading.
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 such as gloves, aprons, and boots. Coveralls or long sleeve shirts and pants may be necessary for 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. 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 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 VINYL ACETATE LOADING PROJECTS
Vinyl Acetate 101
Things to know about vinyl acetate
Vinyl acetate is regulated by the U.S. Department of Transportation (DOT) and is classified as a flammable material with the DOT identification number UN 1301.
Vinyl acetate is an industrial chemical that is produced in large quantities in the United States. It’s a clear, colorless liquid, and is slightly soluble in water with a sweet, fruity aroma. Vinyl acetate is a very flammable liquid and vapor and can be ignited by heat, sparks, or flames. Vinyl acetate is used in the production of many industrial chemicals, primarily to make glues for packaging and the building industry. It’s also used in the production of paints, textiles, paper, and as a coating in the making of plastic films.
Only properly trained and equipped personnel should be permitted to load or unload vinyl acetate tank cars and tank trucks. Operators should wear approved PPE equipment including impervious clothing, footwear, gloves, and goggles.
Vinyl acetate can be hazardous to human health and acute exposure can cause respiratory irritation and organ toxicity. Do not breathe dust, fumes, mist, or vapors. Use only outdoors, or in a well-ventilated area.
First-aid measures for exposure include:
- Remove 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 do not induce vomiting, but immediately call your local poison control center.
Aspiration into the lungs can cause fatal chemical pneumonitis. If ingestion has occurred, assume there is a risk of aspiration into the lungs. Vinyl acetate is not corrosive and works well with aluminum and stainless steel. Carbon and milled steel are rated “C” or “fair” with softening and/or loss of material strength; therefore it is not recommended for long-term use.
Is your plant or facility compliant with ANSI, OSHA, and local safety codes? We can help!
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.
