Hazards of Phenol - Safety precautions & preparations for loading- Chemical Tanker Solutions
Phenol is derived from the basic raw materials of benzene and propylene. Phenol is typically a solid at room temperature as it solidifies at 41°C (106 °F). Plywood, window glazing, DVDs, computers, automotive parts and LCD/LED TVs are some of the many items that rely on this important raw material.
Recommended Precautions & Preparations:
Heating instructions of the Shipper or Owners must be followed to avoid cargo related claims. Sufficient toxic gas measuring tubes must be available before commencement of loading. Polyethylene glycol -300 or 400 (PEG) must be immediately available at the manifold, along with sufficient quantity of cotton wool. All personnel involved in the handling of phenol should be familiar with MSDS for phenol. Crew members involved in the operation should be equipped with proper safety equipment / devices NIOSH and/or OSHA-approved.

All personnel involved in the handling of phenol should be familiar with MSDS for phenol. Crew members involved in the operation should be equipped with proper safety equipment / devices NIOSH and/or OSHA-approved.
Before loading all lines, valves and systems must be pressure tested. Common lines and excessive bends, hoses as far as possible must not be used. If simultaneous loading is done through a Y piece, then precaution must be taken to prevent freezing of cargo. After loading and during passage regular turning of pumps must be done to prevent impeller freezing.
Loading guideline:
Tanks nominated for Phenol must be cleaned for Water White Standard. Some shippers might require Methanol Standard. All hose/pipe connections associated with Phenol operation must be tested with high pressure nitrogen. Tanks to be loaded should have ballast removed from underneath and heating coils must be opened once product has fully covered the coils. The fire main must be pressurized throughout; Steam and hot water should be available during loading period.
Topping Off:
Loading rates to each tank must be adjusted to minimize the chances of product freezing in the lines before they can be blown. Individual lines and manifolds must be blown through to avoid residues in line. If cargo tanks are fitted with a drop line great care must be taken to load simultaneously part of the cargo through the pump stack in order to prevent blocking of the cargo line between the delivery valve of the pump and the drop line valve. Closed sampling system should be used.
Care at passage:
Phenol must be carried at temperatures within charterers instructions, typically between +50 and + 60 degrees C. Heating instructions of the Shipper or Owners must be followed to avoid protests and delays in the port of discharge. Overheating can damage this cargo. A full cargo heating log must be maintained.
High melting point cargoes such as Phenol, Palm fatty acid distillates lauric and Stearic acid has inherent property to form lumps of cargo. It is therefore recommended to turn the cargo pumps at regular intervals during the voyage and prior to discharge in order to avoid any last minute surprises. All the lines to be then blown back to the cargo tanks.
The danger of frozen valves, pressure/vacuum in the tanks to be monitored during loading, voyage and discharge. In the event if any of the pumps are found frozen, deployment of portable Framo pump should not be considered without a proper RA and office permission.
Discharging:
Care must be taken during the initial stages of discharge to ensure that all associated lines /valves are unblocked by applying either external live steam or hot water. The fire main is to be pressurized and Nitrogen is available for blowing cargo lines. A tank dry certificate is issued immediately after completion.
Cleaning: :
Phenol is a category “Y” substance and depending on the discharge temperature, should be pre-washed in accordance with MARPOL requirements (Solidifying Substances). Prewash is not required if cargo temperature is 10 degrees C above the freezing point at the time of discharge.
Hazards of Phenol:
Some examples of accidents with Phenol:
A lump of phenol has crystallized on the bottom of the man lid (sloshing of load). After opening of the man lid the lump of crystals fall down and cause a splash of hot phenol liquid upwards. A vapor return line (or a product line) gets plugged with solid phenol. Line is pressurized and heated. Phenol plug suddenly gives way and pressure levels instantaneously. Phenol sprays or physical damage from pressure.

Hazards of Phenol:
- Health Hazards: Toxic by inhalation, in contact with skin and if swallowed. Causes burns. Phenol can be rapidly absorbed through skin causing systemic poisoning and possibly death.
- Safety Hazards: Combustible liquid. Risk of explosion, if heated under confinement.
- Environmental Hazards: Toxic to aquatic organisms.
Some examples of accidents with Phenol:

A vapor return line (or a product line) gets plugged with solid phenol. Line is pressurized and heated. Phenol plug suddenly gives way and pressure levels instantaneously. Phenol sprays or physical damage from pressure.
First Aid::
- Inhalation: Remove to fresh air and resuscitate with medical oxygen.
- Skin Contact: To remove phenol from a small affected body area (10% of body area or less) remove any contaminated clothing and swab the area promptly and repeatedly with cotton soaked in PEG then wash with water for more than 5 min. If a larger body area has been contaminated, immediately remove all phenol contaminated clothing and shoes under a shower with lukewarm, gently flowing water. After several minutes flushing, decontaminate with swabbing or spraying with PEG.
- Eye Contact: Immediately flush eyes with large amounts of water for at least 30 minutes while holding eyelids open.
- Ingestion: Do not induce vomiting. If victim is alert, rinse mouth and drink 1/2 to 1 glass of water to help dilute the material. Do not give liquids to a drowsy, convulsing, or unconscious person.
- Ensure the suitability of the vessel for carrying phenol with respect to its stowage restrictions and operations on the whole.
- Ensuring crew is well informed and trained to handle such cargoes.
- Ensuring a blend of experienced officer and crew on board so as to Properly train the inexperienced staff for their future endeavours With specific cargo operations
- Proper check/pressure testing of lines and valves prior loading.
