Phenol (C6H5OH) Handling Design, Loading, and Installation.

Phenol is used primarily in the production of phenolic resins and in the manufacture of nylon and other synthetic fibers.

Phenol is an aromatic organic compound with a molecular formula of C6H5OH. A mildly acidic toxic white crystalline solid obtained from coal tar and used in chemical manufacturing. In a diluted form, under the name of carbolic acid, it’s used as a disinfectant. Due to its acidic properties, Phenol requires careful handling due to its likelihood to cause chemical burns.

In the United States, Phenol is a “tight-fill” (closed-loop) loading operation and is loaded into road tankers and rail cars via chemical hoses or top loading arms with vapor recovery. Phenol, if not handled properly can be fatal therefore 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.

Phenol is typically transported in DOT 103 general service tank cars or approved DOT trailers include MC 300 thru MC 312 , MC 330 and MC 331.

Phenol is typically transported in a molten state via insulated, DOT 103 general service tank cars with safety valves. The rails cars themselves are 9′ outside diameter with an overall length of ~47′, with a 6’ x 6′ or 8’ x 8’ centered crash box.

Tank truck (un)loading procedures are similar to railcar applications with the trailers meeting established DOT requirements for hauling phenol or similar commodities.

Approved DOT trailers include MC 300 thru MC 312 , MC 330 and MC 331. All trailers must be equipped with pressure relief valves; and trailers with bottom outlets must be equipped with remote-controlled stop valves.

Phenol Loading Arms
	Phenol is typically loaded into railcars via chemical hoses or loading arms. The current best loading practice is to use a 3″ chemical hose or a carbon steel loading arm with quick-acting coupling, often in the form of Hammer Unions with stabber pipe. The hose or arm 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. Break-away couplings can be fitted near the inlet of the hose for additional safety in the event of a premature departure.
Loading Gangways and Safety Cages
	A wider access gangway (36″-48″ 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’ 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 use Retractalok power-assist technology allowing operators to raise or lower effortlessly, light as a feather to lift, solid as a rock. Tested in the most critical applications, this revolutionary new gangway outperforms all others. Available in multiple lengths and widths. Learn More
Phenol 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
Phenol Spill Containment
	Spill containment pans will be provided at the point of loading operations and is an essential piece of equipment in overall site safety and environmental protection Railcar spill containment and track pans
Phenol Grounding
	Phenol is highly flammable, and industry best practice includes the grounding of all vessels before starting the (un)loading process. Vehicle grounding and bonding — ensure true grounding before product flow is permitted Explosion-proof enclosures — meet or exceed UL, CSA and Ex requirements
Phenol Safety Gates
	Safety Gates will be installed at the top of stairs and any other openings to ensure operator safety at all times. YellowGate Safety Gates SafeRack’s line of industrial safety gates is the most flexible product on the market with the ability span openings between 16” and 36” and is field adjustable with nothing more than a wrench.

Phenol Options
	Lighting – Lighting both over and under the platform will be provided. For overcast days or second shift, lighting is essential for improved safety and improved productivity. Platform & Canopies – Full platform canopies reduce exposure to the elements and improve the safe and productive loading operation from the operator’s perspective. Operator Shelter – Depending on your site requirements, consideration should be given to the requirement of 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 e.g. gloves, aprons, boots. Coveralls or long sleeve shirts and pants 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 Phenol; 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 (e.g. double mechanical pump seals) to prevent the release of this material due to equipment failure.

Phenols are also used in household products and as intermediates for industrial synthesis. For example, phenol in low concentrations is used as a disinfectant in household cleaners, and even in mouthwashes. Phenol may have been the first surgical antiseptic. Phenol can be very dangerous, and the hazards are not just those of a typical corrosive. The dangers of phenol are two-fold. It’s both a corrosive (can cause severe burns) and a toxic (if absorbed phenol acts as a systemic toxin). Death was reported from the ingestion of as little as 15ml. Again, the primary hazard of phenol is its ability to penetrate the skin rapidly, causing severe burns, and its toxicity even in small amounts. Due to its local anesthetizing properties, skin burns may be painless.

Phenol is considered a Category 4 flammable liquid by OHSA and has a flashpoint of 79 degrees C and 174 degrees F. During a fire, phenol may decompose into hazardous carbon monoxide and carbon dioxide. Phenol doesn’t work well with most metals, rubber, plastics, or alloys.

Track Mounted Gangway — Helping a chemical company access their tanker truck

Phenol is typically loaded (tight-fill) into the tops of rolling stock/tank trucks and unloaded from the bottom. Variations on the preferred method of loading include a close dome, tight fill, splash fill with cover plate and vapor recovery, and tight fill with dry break couplers.

Best practices for phenol loading/unloading include: wearing a chemical suit, rubber gloves, splash goggles, face shield, rubber boots, and a self-contained breathing apparatus (SCBA). Because operators are regulated to wear a restrictive chemical suit, SafeRack suggests the use of a wider gangway and a MAX Rack for more ergonomic access and egress. A wider gangway will reduce the risk of the operator’s PPE getting caught, torn, or damaged, as well as address offset crash boxes.

To protect operators, SafeRack offers numerous options for fall prevention safety cages, including- two, three, and four rail designs.

Best practice includes the grounding of all vessels before starting the (un)loading process. For overcast days or second shift, lighting is an inexpensive and is essential for safety and improved productivity. Safety showers and eyewash stations should have alarms to alert workers of possible exposure.

SafeRack understands that accidents can happen. Properly equipping your loading terminal with rail or truck spill containment will save costly cleanup, downtime, and EPA/OSHA fines. In the event of a chemical release or spill, operators need to stay upwind. Having a windsock on your platform provides a visual reference to help keep workers out of harm’s way in the event of an emergency.

Phenol is a mildly acidic toxic white crystalline solid obtained from coal tar and used in chemical manufacture and a diluted form (under the name carbolic) as a disinfectant. Phenol is an aromatic organic compound with a molecular formula C6H5OH. The molecule consists of a phenyl group bonded to a hydroxy group. It’s mildly acidic and requires careful handling due to its likelihood to cause chemical burns.

Phenol can be tasted and smelled at levels lower than those associated with harmful effects. Phenol evaporates slower than water and can form a solution with water. Primarily, phenol is used in the production of phenolic resins and the manufacture of nylon and other synthetic fibers.

Petrochemicals are made from either petroleum or natural gas feedstock. A wide variety of petrochemicals are created/produced depending on the process.

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.
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.
