White de-icing Salt


Material Safety Data Sheet

1. Identification of the Substance

Product name: White Marine Salt
Chemical name: Sodium Chloride
CAS Number: 007647 14 5
EINECS Number: 231 598 3
Formula: NaCl

2. Identification of company:

Water Softener Salt UK
134 Seaford Road
London N15 5DS

0203 286 7367

3. Composition White De-icing salt

Sodium Chloride 99.9%

4. Physical and Chemical Properties

Physical State White Crystalline solid, Odourless
Boiling Point 1413°C
Melting Point 802°C
Bulk Density 1.2 - 1.5 gm/ml
Density of Sodium Chloride up to 2.165 g/ml at 20 Deg C
Water Solubility Freely Soluble

5. Hazards Identification

Inhalation Very high concentration of salt dust may result in
inflammation of the mucus of the respiratory tract
Skin Contact Dry salt and concentrated solutions can cause withdrawal
of fluid from the skin. Repeated and /or prolonged skin
contact may cause irritation.
Eye Contact Salt and salt solutions are not toxic to the eye but
concentrations much above that of tears cause a stinging
Ingestion Wash out mouth with water and give 200-300ml (half a
pint) of water to drink. Obtain medical attention if illeffects
occur. Further Medical Treatment: Symptomatic
treatment and supportive therapy as indicated.

6. First aid measures

Inhalation Remove patient to fresh air. Keep warm and at rest. Give
drinks if required
Ingestion Vomiting will probably occur. Wash out mouth with
water and give 200-300ml (half a pint) of water to drink.
Obtain immediate medical attention especially if
vomiting has not occurred.
Eye Contact Irrigate with eyewash solution or clean water, holding the
eyelids apart, for at least 10 minutes. If symptoms
develop, obtain medical attention.
Skin Contact Wash skin with plenty of water

7. Fire fighting measures

Flammability Non-flammable
Extinguishing Agents Use agents suitable for type of surrounding fire (dry
chemical, CO2, water, spray or foam).
Special hazards Salt withstands temperatures up to its melting point
without decomposing, but at very high temperatures
(greater than approximately 800°C) a vapour may be
emitted which is particularly irritating to the eyes
Protective equipment As applicable to the combustion products associated with

8. Accidental release measures

Personal precautions Avoid prolonged contact with the skin and inhalation of
dust concentrations, otherwise normal good handling
and house keeping practice is adequate. No special
protective clothing is required. An eyewash bottle with
clean water should be made available.
Spillages • Clear up spillages.
• Transfer to a container for disposal.
• Wash the spillage area with water.
• Spillages or uncontrolled discharges into water courses,
drains or sewers must be IMMEDIATELY alerted to the
Environment Agency or other appropriate regulatory

9. Handling & Storage

Handling Avoid contact with eyes. Avoid prolonged skin contact.
Atmospheric levels should be controlled in compliance with the
occupational exposure limit for dust. Keep away from strong acids
and common metals. Static electricity can be generated by
pneumatic conveying, therefore pipes should be bonded and
earthed, especially where a spark could prove hazardous.
Storage Keep away from concentrated acids. White salt can be stored
outside. Care should be taken to avoid excessive run-off into
water or onto vegetation

10. Exposure Controls

Long Term Exposure Repeated ingestion of excessive amounts may cause
disturbance of body electrolyte and fluid balance.

11. Personal Protection

Wear suitable protective clothing, gloves and eye/face protection. An approved
dust mask should be worn if exposure to levels above the occupational exposure
limit is likely.
Occupational Exposure Standard (UK HSE Guidance Note EH40)
Time Weighted Average mg/m 3(ppm)
Dust (Total Inhalable Dust) 10
Dust (Respirable Dust) 4

12. Stability and reactivity

Chemical stability Stable
Conditions to avoid Reacts with strong sulphuric acid or nitric acide to give
hydrogen chloride gas
Material to avoid Under wet conditions salt can corrode many common metals,
particularly iron, aluminium and zinc
Hazard decomposition products Trace amounts of hydrogen chloride gas can be
evolved at temperatures in excess of 800°C. Does not
react with alkalis at ordinary temperatures.

13. Toxicological information

Eyes Dust may be irritating
Skin Will remove the natural greases resulting in dryness,
cracking and possibly dermatitis. Repeated and /or
prolonged skin contact may cause irritation.
Ingestion May cause vomiting and diarrhoea. The swallowing of
small amounts is unlikely to cause any adverse effects.
Inhalation High concentrations of dust may be an irritant to the
respiratory tract.
Carcinogenicity Not considered to be a carcinogen.
Mutagen city Not considered to be a mutagen.
Reproductive effects None identified.

14. Disposal considerations

Disposal should be in accordance with local or national
