Burning Sulfur decomposes into TOXIC sulfur oxide gasses
dioxide (SO2) and Hydrogen
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
Wear full-faced, self-contained breathing apparatus and full protective clothing. 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 310oF (154oC). Cool surrounding
areas with water fog to prevent re-igniting. Cool containers, tank cars, or trailer loads
with flooding quantities of water until well after fire is out. Evacuate nonessential
personnel from the fire area. If large fire, evacuate people downwind from fire. Isolate
for ½ mile in all directions, consider evacuation for ½ mile in all directions. Prevent
human exposure to smoke, fumes, or products of combustion (sulfur oxide gases). Firemen
exposed to contaminated smoke should be immediately relieved and checked for symptoms of
exposure to toxic gasses. Seek medical attention immediately! . This should
not be mistaken for heat exhaustion or smoke inhalation. These are extremely
irritating to the respiratory tract and may cause breathing difficulty and pulmonary
edema. Symptoms may be delayed several hours or longer depending upon exposure.

SECTION 4 REACTIVITY DATA
Conditions to Avoid (Instability): Keep from heat sources, sparks, and open flames.
Materials to Avoid (Incompatibility): Oxidizing agents, may react violently. Corrosive to
copper and copper alloys. Damp sulfur will corrode steel. Hazardous Polymerization: Will
Hazardous Decomposition Products: Oxides of sulfur gasses produced by burning sulfur.
SECTION 5 HEALTH HAZARDS
Sulfur is essentially non-toxic either through ingestion, inhalation, skin or eye contact.
Individuals with known allergies to sulfide drugs may also have allergic reactions to
SIGNS AND SYMPTOMS OF OVEREXPOSURE
Nose or throat irritation, coughing, chest discomfort, asthma, difficulty breathing,
nausea, vomiting, stinging eye irritation, skin irritation, hives.
EMERGENCY AND FIRST AID:
No adverse effects. Skin irritation may be aggravated in persons with existing skin
lesions. Wash exposed clothing separately before reuse. First Aid: Wash skin
with plenty of mild soap and water.
Sulfur dust is an eye irritant. Avoid contact with eyes, especially contact wearers. Wear
safety glasses. First Aid: In case of contact, immediately flush eyes with
plenty of water for a minimum of fifteen minutes. Hold upper and lower lids apart to
insure rinsing of the entire eye surface and lids. Do not use boric acid to rinse with;
sulfur is an acid irritant. FOR SEVERE IRRITATION, GET MEDICAL ATTENTION, preferably an
Prolonged inhalation may cause irritation of the respiratory tract. Breathing of dust may
aggravate asthma and other pulmonary diseases. Individuals with known allergies to sulfide
drugs may also have allergic reactions to elemental sulfur dust. Maintain adequate
ventilation in area where dust is present. Wear dust masks and use NIOSH/MSHA approved
dust respirator if airborne concentrations exceed exposure limits. First Aid:
Move patient to fresh air. Watch for signs of allergic reaction. Use a bronchodilator
inhaler if directed by asthma patient. Keep victim warm and quiet. If not breathing, clear
airway and start mouth-to-mouth resuscitation. If heart has stopped beating, start
cardiopulmonary resuscitation (CPR). GET MEDICAL ATTENTION.
Ingested sulfur is converted to sulfides in the gastrointestinal tract, and ingestion of
10 to 20 grams has caused irritation of the GI tract and renal injury. Individuals with
known allergies to sulfide drugs may also have allergic reactions to elemental sulfur.
Swallowing large amounts may cause nausea and vomiting. Do not eat sulfur. First
Aid: For large amounts ingested, if the victim is conscious and alert, give two or
more glasses of water to drink. If available, give one tablespoon of Syrup of Ipecac to
induce vomiting. If vomiting does occur, give fluids again. If vomiting has not occurred
in twenty minutes, the same dose of Syrup of Ipecac may be repeated one additional time.
Alternatively, vomiting may be induced by touching the back of the throat with a finger.
Do not give anything by mouth to an unconscious or convulsing person. GET MEDICAL

CARCINOGENICITY, TERATOGENICITY, MUTAGENICITY:

SECTION 6 PRECAUTIONS FOR SAFE
HANDLING AND USE
Containers should be stored in a cool, dry, well ventilated area. Keep container tightly
closed. Store away from flammable materials, sources of heat, flame and sparks. Separate
from chlorates, nitrates and other oxidizing agents. Exercise due caution to prevent
damage to or leakage from container.
Avoid any conditions that might tend to create a dust explosion. Be careful not to create
dust. Maintain good housekeeping practices to minimize dust build-up and dispersion.
Eliminate sources of ignition. Keep away from heat, sparks and flames. Use nonferrous
tools to reduce sparking. Sweep or shovel up spilled material using a natural fiber broom
and/or aluminum shovel to prevent sparking. Maintain adequate ventilation in all areas.
SMALL or LARGE SPILLS:
No flares or flames in area. No smoking. Danger of dust explosion near sparks. Sweep or
shovel up spilled material using a natural fiber broom and/or aluminum shovel to prevent
sparking. Place sweepings in an appropriate chemical waste container for reclaiming or
disposal in an approved facility. Wash spill site after clean up is complete. Wear
protective clothing during clean up: safety glasses, rubber gloves, impervious clothing,
dust mask or respirator.
SECTION 7 PROTECTIVE EQUIPMENT
Protective equipment should be used during the following procedures:
- Manufacture or formulation of this product.
- Repair and maintenance of contaminated equipment.
- Clean up of leaks and spills.
- Any situation which may result in hazardous exposure.
Maintain adequate ventilation and wear a respirator or a dust mask to prevent inhalation.
Wear suitable, protective clothing and safety glasses to prevent skin and eye irritation
from dust. Maintain a sink, safety shower and eyewash fountain in the work area. Wash skin
thoroughly after handling and before eating or smoking. Wash contaminated clothing
separately before reuse.
