TYPES OF HAZARD
/ EXPOSURE
Formula: S or S8
Molecular mass: 256.5 (S_8) Atomic mass: 32.1
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
Combustible.
NO open flames,
NO sparks and
NO smoking.
Use water spray, foam, powder,
dry sand.
Finely dispersed particles form explosive
mixtures in air.
In case of fire: keep drums, etc.,
cool by spraying with water.
EXPLOSION
Closed system,
ventilation,
explosion-proof
electrical
equipment and
lighting. Prevent
deposition of
dust. Prevent
build-up of
electrostatic
charges (e.g., by
grounding).

attention.
Redness.
Protective
gloves.
Remove contaminated clothes.
Rinse and then wash skin with
water and soap.
Redness. Pain. Blurred vision.
Wear safety
goggles.
First rinse with plenty of water for
several minutes (remove contact
lenses if easily possible), then refer
for medical attention.
Burning sensation. Diarrhoea.
Do not eat, drink,
or smoke during
work.
Rinse mouth. Refer for medical
attention .

SPILLAGE DISPOSAL
Personal protection: particulate filter respirator adapted
to the airborne concentration of the substance. Sweep
spilled substance into covered containers. If appropriate,
moisten first to prevent dusting.

EMERGENCY RESPONSE
SAFE STORAGE
Transport Emergency Card: TEC (R)-115A.
NFPA Code: H1; F1; R0.
Fireproof. Separated from strong oxidants.
IMPORTANT DATA
Physical State; Appearance
YELLOW SOLID IN VARIOUS FORMS.
Routes of exposure
The substance can be absorbed into the body by
inhalation and by ingestion.
Physical dangers
Dust explosion possible if in powder or granular form,
mixed with air. If dry, it can be charged electrostatically
by swirling, pneumatic transport, pouring, etc.
Chemical dangers
On combustion, forms toxic and corrosive gases of sulfur
oxides including sulfur dioxide (see ICSC 0074). Reacts
violently with strong oxidants , especially if powdered.
This generates fire and explosion hazard.
Occupational exposure limits
TLV (NOT-ESTABLISHED):.
Inhalation risk
Evaporation at 20°C is negligible; a harmful
concentration of airborne particles can, however, be
reached quickly when dispersed.
Effects of short-term exposure
The substance is irritating to the eyes, skin and
respiratory tract. Inhalation of the powder may cause
inflammation of the nose and respiratory tract.
Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause
dermatitis. The substance may have effects on the
respiratory tract. This may result in chronic bronchitis.
PHYSICAL PROPERTIES
ENVIRONMENTAL DATA
Boiling point: 445°C
Melting point: 120°C (amorphous)
Melting point: 107°C (r-sulfur)
Melting point: 115°C (beta-sulfur)
Density: 2.1 g/cm³
Solubility in water: none
Flash point: 160°C c.c.
Auto-ignition temperature: 232°C
Explosive limits, vol% in air: 35-1400 g/m³
NOTES
Often transported in molten state (UN 2448; TEC(R)-115).
Molten sulfur reacts with hydrocarbons to form toxic and flammable gases.
Depending on the degree of exposure, periodic medical examination is indicated.
