What is the ignition temperature of sulphur?
The minimum reported value for the flash point of dark crude sulphur is 168°C (335°F). Sulphur dust suspended in air is readily ignited by flame, static electricity or friction spark. The dust is characterized by a very low ignition point of 190°C (374°F) compared to other combustible dusts.
Is sulfur dust flammable?
Flammable solid with a relatively low ignition temperature. Sulfur dust ignites easily in air. Grinding sulfur may produce an explosion hazard. Static discharge may ignite sulfur dust.
What is the flammability of sulfur?
Hazard Class: 4.1 Molten Sulfur is a FLAMMABLE SOLID and a fire and explosion risk above 450 oF (232 oC). Sulfur is a COMBUSTIBLE SOLID. Use water spray to fight fires and to keep fire-exposed containers cool. POISONOUS GASES ARE PRODUCED IN FIRE, including Hydrogen Sulfide, Sulfur Dioxide and Sulfur Trioxide.
What is the flash point of sulfur?
160°C c.c.
Flash point: 160°C c.c. The substance can be absorbed into the body by inhalation and by ingestion. The substance is irritating to the eyes, skin and respiratory tract.
What happens if you breathe in sulfur?
What immediate health effects can be caused by exposure to sulfur dioxide? Inhaling sulfur dioxide causes irritation to the nose, eyes, throat, and lungs. Typical symptoms include sore throat, runny nose, burning eyes, and cough. Inhaling high levels can cause swollen lungs and difficulty breathing.
How do you put out a sulphur fire?
Use a water fog to extinguish fire. Do not use solid streams of water; which could create sulfur dust clouds and cause an explosion or move burning sulfur to adjacent areas. Fire will rekindle until mass is cooled below 310 oF (154oC).
What are precautions to be taken while heating Sulphur?
Precautionary Statements: P210 Keep away from heat/sparks/open flames/hot surfaces – No smoking, P280 Wear protective gloves/protective clothing/eye protection/face protection. INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek medical attention if symptoms persist.
What are the dangers of sulfur?
Sulfur is low in toxicity to people. However, ingesting too much sulfur may cause a burning sensation or diarrhea. Breathing in sulfur dust can irritate the airways or cause coughing. It can also be irritating to the skin and eyes.
Can you start a fire with sulfur?
Sulfur dust suspended in air ignites easily, and can cause an explosion in confined areas. May be ignited by friction, static electricity, heat, sparks, or flames. Toxic gases will form upon combustion. Bulk/solid forms burn only at moderate rate, whereas dust burns with explosive violence.
How is minimum ignition temperature of sulfur dust measured?
Measurement of minimum ignition temperature of sulfur dust layer (MIT-L) The measurement of minimum ignition temperature of sulfur dust layer was carried out at a hot plate (shown in Fig. 1), which was heated by heating wires. The minimum temperature of the hot surface was detected as the specific thickness of the dust layer fires.
What should be the concentration of sulfur dust?
The dust concentration should be controlled at 200g/m 3 or less in the production of sulfur. When the dust concentration was 1500g/m 3 , explosion pressure and explosion index remained high which showed that sulfur dust with a higher explosion limit was easy to form explosive dust cloud.
How does sulfur dust affect the explosion risk?
The explosion risk and strength of sulfur dust decreased with the increase of the particle size. The minimum ignition energy and the minimum ignition temperature increased as the water content increased. The maximum explosion pressure and the explosion index rose at first and went down latter as the dust concentration increases.
How to know if you are allergic to sulfur?
Individuals with known allergies to sulfide drugs may also have allergic reactions to elemental sulfur . .•. SIGNS AND SYMPTOMS OF OVEREXPOSURE Nose or throat irritation, coughing, chest discomfort, asthma, difficulty breathing, nausea, vomiting, stinging eye irritation, skin irritation, hives . .•.
