Fire hazard of phenol
Thread Content
Dear sea friends, what category does the fire hazard of phenol fall into? I searched online for a long time but couldn’t find the right category. Furthermore, if phenol is stored above its melting point, for example at around 60 degrees, what category does its fire hazard fall into? I’ve been unable to decide which category this should be placed in the table below. Thank you all here. Fire hazard characteristics by production categoryProduction involving the use or generation of the following substances:
Class A: 1, 2, 3, 4, 5, 6, 7 – Liquids with a flash point below 28°C; gases with a lower limit of less than 10%; substances that can decompose on their own at room temperature or oxidize in air to cause rapid self-ignition; substances that produce flammable gases when exposed to water or water vapor at room temperature, thereby causing combustion; substances that are highly prone to ignition upon contact with acids, heat, impact, friction, catalysts, or flammable inorganic substances such as organic compounds or sulfur; strong oxidizers that can cause combustion upon impact, friction, or contact with oxidizers or organic compounds. Production carried out in enclosed equipment at temperatures equal to or above the substance’s own auto-ignition point.
Class B: 1, 2, 3, 4, 5, 6 – Liquids with a flash point of 28°C or higher but less than 60°C; gases with a lower limit of 10% or higher; oxidizers that do not fall under Class A; chemically flammable solid substances that do not fall under Class A; oxidizing gases; dust, fibers, or particles in a suspended state that can form explosive mixtures with air; liquid droplets with a flash point of 60°C or higher.
Class C: 1, 2 – Liquids with a flash point of 60°C or higher; combustible solids.
Class D: 1, 2, 3 – Production involving the processing of non-combustible substances, with frequent generation of intense radiant heat, sparks, or flames at high temperatures or in molten states. Production that uses gases, liquids, or solids as fuels, or that involves burning gases or liquids for other purposes. Production involving the use or processing of difficult-to-combust substances at room temperature.
Class E: Production involving the use or processing of non-combustible substances at room temperature.
Classification of hazardous chemicals: Phenol belongs to Category 6.1 – Toxic substances.

Hazard category: Route of exposure: Health hazards: Phenol has a strong corrosive effect on skin and mucous membranes; it can suppress the central nervous system or damage liver and kidney functions. Acute poisoning: Inhaling high concentrations of vapor can cause headache, dizziness, fatigue, blurred vision, pulmonary edema, etc. Accidental ingestion causes burns to the digestive tract, resulting in burning pain; exhaled breath has a phenolic odor, and vomiting or stools may contain blood. There is a risk of gastrointestinal perforation, as well as shock, pulmonary edema, liver or kidney damage, acute renal failure, and death due to respiratory failure. Eye contact can cause burns. It can be absorbed through burned skin, and after a certain incubation period, it causes acute renal failure. Chronic poisoning: It can cause headache, dizziness, cough, loss of appetite, nausea, and vomiting; in severe cases, it can lead to proteinuria. It can cause dermatitis. Environmental hazards: It causes serious harm to the environment, potentially polluting water bodies and the atmosphere. Fire and explosion hazard: This product is flammable, highly toxic, and highly corrosive; it can cause burns to the human body. Part 4: First Aid Measures Back to Table of Contents Skin contact: Immediately remove contaminated clothing, scrub with glycerin, polyethylene glycol, or a mixture of polyethylene glycol and alcohol (7:3), and then wash thoroughly with water. Or rinse with plenty of flowing water for at least 15 minutes. Seek medical attention. Eye contact: Immediately lift the eyelids and rinse thoroughly with plenty of flowing water or saline for at least 15 minutes. Seek medical attention. Inhalation: Quickly move to a place with fresh air. Keep the airway clear. If there is difficulty breathing, administer oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. Ingestion: Immediately administer 15–30 mL of vegetable oil. Induce vomiting. Seek medical attention. Part 5: Fire-fighting measures Return to table of contents Hazardous properties: Flammable in the presence of open flames or high temperatures. Harmful combustion products: carbon monoxide, carbon dioxide. Fire extinguishing method: Firefighters must wear gas masks and full protective firefighting suits, and extinguish the fire from the upwind direction. Extinguishing agents: water, alcohol-resistant foam, dry powder, carbon dioxide. Section 6: Emergency Response to Leaks Return to Table of Contents Emergency Response: Isolate the area affected by the leak and restrict access. Cut off the source of fire. It is recommended that emergency responders wear dust masks (full-face masks) and protective suits. Minor leaks: Cover with dry lime or soda ash. Large-scale leakage: Collect, recycle, or transport to a waste disposal facility for disposal.
