(011) 608-3300 or Toll free: 0800-1144455
: Sulphur solid
S8
3. Hazards identification :
Highly flammable and combustible Solid. A nuisance dust. Crystalline sulphur deposits and dust are readily
ignitable. Forms explosive mixtures with charcoal and oxidizing agents. Thermal decomposition will evolve
with large quantities of sulphur dioxide.
In dry state can form electrostatic charge if stirred, transported pneumatically or poured.
Contact could cause burns to skin and eyes.
Fire could produce irritating or Sulphur dioxide (SO2) gas. Threshold Limit value (TLV) of 2ppm / Short term
exposure limit (STEL) = 5ppm
Run-off from fire-control or dilution water could cause pollution.
Eye contact: Irritation and redness.
Inhalation: sore throat, coughing.
3
No recommended dust exposure limit therefore considered a nuisance dust. ACGIH 10mg/m (total dust) or
3
5mg/m (as respirable dust)
4. First Aid :
Specific Immediate Treatment
Skin
: Remove contaminated clothing, wash skin with soap
and water or shower.
Eyes
: IMMEDIATELY wash eyes with running water until
irritation is gone. Take to doctor if necessary.
Ingestion
: Rinse mouth with water and do not induce vomiting.
Obtain medical attention. Sulphur is not considered
highly toxic.
Inhalation (SO2 gas, smoke, dust or H2S)
: Move to fresh air. Take to doctor.
5. Fire fighting :
Requirements for fire fighting
Extinguishing Medias
: Water, water fog, Dry chemical powder fire
extinguisher, sand, water spray or foam.
Fires
: Protect product and containers from ignition during
nearby fires if possible.

SOLID SULPHUR
Respiratory equipment
: Breathing Apparatus set
Unusual fire and explosion hazards
: Combustion product is sulphur dioxide, an irritating
toxic gas which smells like burning match heads.
Dust air mixtures are highly flammable / explosive.
Sulphur fires are deep blue at night, with very short
flames. Fire is invisible in the daylight except for smoke
and heat. Burning material turn deep red black.
6. Accidental Release :
Precautions
: Avoid mixtures of air and sulphur dust, sparks or open
flames, mixtures of sulphur and oxidizing agents in
general, large accumulations of sulphur dust which
become airborne in an explosion or process disruption
caused by other materials. Examples of oxidizing
agents are perchlorates, nitrates, chlorates,
permanganates, peroxides, oxygen and etc.
Good house keeping is essential to minimize fire
danger.
: Restrict access to area.
Provide adequate protective equipment, ventilation and
have fire fighting equipment at hand.
Remove sources of heat, flame and ignition.
Avoid setting fire to spilled material.
Avoid creating dust and sparks with tools.
Small spills may be cleaned up with a shovel and
broom.
Large spills may be cleaned up with front end loaders.
Personnel to thoroughly wash all exposed skin areas to
prevent irritation from dust.
Spill or Leak
: Do not let spillages enter drains, sewers or water
courses. Any spillages into the water courses must be
reported to the local regulatory body, of that area.
Environmental
7. Handling and Storage :
Handling and storage
:
Handle only with well grounded non-sparking
equipment.
Dry sulphur materials may generate static electricity
and sparking.
Avoid handling sulphur at high velocity in air.
Control dust formation.
Avoid contact with eyes and dust suspections.
Only use in well ventilated areas.
Do not use near sparking equipment or open flames.
Do not allow large amounts of waste to accumulate.
Do not store near oxidizing materials or near hot
equipment.
In the presence of moisture over long periods of time,

sulphur will convert to sulphuric acid which is corrosive
to metals, attacks paper, concrete, wood. Store in dry
place
8. Exposure and Personal Protection :
Occupational Exposure Limits
: No Exposure Limits Established
Personnel Protective Equipment
: Respiratory protection: dust mask suitable for use of
irritating dust.
Fire: Breathing apparatus shall be worn.
Indoor use areas should have sufficient local exhaust to
remove dust as it is release into the air.
Eye protection must be used.
Clothing: Long sleeves, long pants and gloves assist to
keep sulphur off the skin of sensitive persons prone to
irritation or dermatitis.
Fire fighting tools should be readily available.
Safety shower or eye wash fountain or bottle to be
available.
