Liquid sulfur

I would like to ask the experts: Are the hazard levels of liquid sulfur and solid sulfur the same during transportation? **Are there any standards in this regard? Thank you~

Solid sulfur is a flammable solid; our storage and transportation of liquid sulfur as well as solid sulfur are designed in accordance with the requirements for Class B fire hazards and explosion prevention.

Part 1: Chemical Name Chinese name of the chemical: Sulfur English name of the chemical: sulfur Other Chinese names: Other English names: Technical data sheet code: Molecular formula: S Molecular weight: 32.06 Part 2: Composition/Ingredients Information Main component: Pure substance CAS No.: 7704-34-9 Part 3: Hazard Summary Hazard category: Route of exposure: Health hazards: It can be absorbed in the body as it is partially converted to hydrogen sulfide in the intestines; therefore, large amounts ingested can lead to hydrogen sulfide poisoning. The systemic toxic effects of acute hydrogen sulfide poisoning are manifested as symptoms of the central nervous system, including headache, dizziness, fatigue, vomiting, ataxia, and coma. This product can cause conjunctivitis and skin eczema. It has a mild irritant effect on the skin. Long-term inhalation of sulfur dust in production generally does not have significant toxic effects. Environmental hazards: Fire and explosion risk: Section 4: First aid measures. Skin contact: Remove contaminated clothing and thoroughly wash the skin with soap and water. Eye contact: Lift the eyelids and rinse with flowing water or saline. 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: Drink plenty of warm water and induce vomiting. Seek medical attention. Part 5: Fire-fighting measures. Hazardous properties: Reacts violently upon contact with halogens, metal powders, etc. Sulfur is a poor conductor, and it easily generates static electricity during storage and transportation, which can lead to fires caused by sulfur dust. Dust or vapor mixed with air or oxidizers forms an explosive mixture. Harmful combustion products: Extinguishing method: Smother with sand to extinguish small fires. In case of a large fire, mist water can be used to extinguish it. Never direct water flow at the molten material, to avoid causing severe flash fires or intense splashing. Firefighters must wear gas masks and extinguish the fire from a safe distance, upwind. Precautions and measures for fire fighting: Section 6: Emergency response to leaks. Emergency handling: Isolate the area contaminated 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 standard work clothing. Do not come into direct contact with the spill. Minor leaks: Avoid creating dust; use a clean shovel to collect the material in a dry, clean, covered container, and transfer it to a safe location. Large leak: Cover with plastic sheeting or canvas. Use non-sparking tools to collect it and take it to a waste disposal facility for disposal. Part 7: Handling, Disposal, and Storage. Handling precautions: Storage precautions: Store in a cool, well-ventilated warehouse. Keep away from flames and heat sources. The package is sealed. It should be stored separately from oxidizers; mixed storage is strictly prohibited. Use explosion-proof lighting and ventilation facilities. The use of mechanical equipment and tools that may generate sparks is prohibited. The storage area should be equipped with suitable materials to contain leaks. Part 8: Exposure Control/Personal Protection Maximum Allowable Concentration: China MAC: No standard established ; Former Soviet Union MAC:6 Monitoring method: Engineering controls: enclosed operation, local exhaust ventilation. Respiratory protection: No special protection is generally required. Wear a self-priming filter dust mask when the dust concentration in the air is high. Eye protection: No special protection is generally required. Body protection: Wear standard work protective clothing. Hand protection: Wear general-purpose protective gloves. Other protections: Smoking, eating, and drinking are prohibited at the work site. Once the work is done, take a shower and change. Pay attention to personal hygiene. Part 9: Physicochemical Properties – Appearance and Characteristics: Pale yellow, brittle crystals or powder with a distinctive odor. PH: Melting point (°C): 119 Boiling point (°C): 444.6 Relative density (water=1): 2.0 Relative vapor density (air=1): No data Saturation vapor pressure (kPa): 0.13 (183.8°C) Heat of combustion (kJ/mol): No data Critical temperature (°C): 1040 Critical pressure (MPa): 11.75 Logarithm of the octanol/water partition coefficient: No data Flash point (°C): Not applicable Ignition temperature (°C): 232 Upper explosive limit (%/V/V): No data Lower explosive limit (%/V/V): 35 mg/m3 Solubility: Insoluble in water, slightly soluble in ethanol and ether, readily soluble in carbon disulfide. Main uses: Used in the manufacture of dyes, pesticides, matches, **, rubber, rayon, pharmaceuticals, etc. Other physical and chemical properties: Part 10: Stability and Reactivity Stability: Conditions to be avoided: Incompatible substances: Strong oxidizing agents. Polymerization hazards: Decomposition products: Part 11: Toxicological data Acute toxicity: LD50: No data available LC50: No data available Subacute and chronic toxicity: Irritation: Sensitization: Mutagenicity: Teratogenicity: Carcinogenicity: Other: Part 12: Ecological data Ecotoxicity: Biodegradability: Non-biodegradability: Bioaccumulation: Other harmful effects: Part 13: Disposal Waste characteristics: Methods of disposal: Part 14: Transport information Hazardous goods number: 41501 UN number: 1350 Packaging marking: Packaging category: O53 Packaging method: Two layers of plastic bags or one layer of plastic bag surrounded by burlap, plastic woven bags, or latex bags ; Plastic bags with composite plastic woven bags on the outside (polypropylene three-in-one bags, polyethylene three-in-one bags, polypropylene two-in-one bags, polyethylene two-in-one bags) ; Ordinary wooden box outside threaded-mouth glass bottles, iron-cap pressed-mouth glass bottles, plastic bottles, or metal drums/tanks ; Glass bottles with threaded mouths, plastic bottles, or tin-plated thin steel sheet drums (tanks), enclosed in floor-grid boxes, fiberboard boxes, or plywood boxes. Transportation precautions: Part XV: Regulatory information. Domestic regulations on chemical safety management: Regulations on the Safety Management of Chemical Hazardous Materials (issued by the State Council on February 17, 1987), Detailed Rules for the Implementation of the Regulations on the Safety Management of Chemical Hazardous Materials (Document No. Hualao Fa 677), Provisions on the Safe Use of Chemicals in the Workplace (Document No. Laobu Fa 423), and other regulations that set out rules regarding the safe use, production, storage, transportation, and handling of chemical hazardous materials ; The Classification and Labelling of Commonly Used Hazardous Chemicals (GB 13690-92) classifies this substance as a Flammable Solid of Category 4.1.

I have this too; what I need is the liquid version, because the risk levels for liquids are different from those for solids!~~

Both liquid and solid fire categories fall under Class B

I seem to have heard somewhere that liquid and solid sulfur have different hazard levels during transportation and storage. **There are documents regarding this; I wonder if anyone knows about it????

This post was last edited by sdqd800 on 2009-12-18 at 12:37. On September 10, 2007, the National Development and Reform Commission issued regulations regarding the transportation of sulfur: to facilitate its import and transportation, while liquid sulfur must be transported using designated tank trucks, solid sulfur can be transported as ordinary cargo. (**The amendment notice No. 1 to the GB12268—2005 Standard for the List of Dangerous Goods, officially issued by the Standardization Administration Committee, specifies that sulfur in a certain shaped form can be transported as ordinary cargo.**) The solid form has UN NO:1350, while the liquid form has UN NO. 2448
