Immediately Dangerous to Life or : 10 ppm
Health
Potential Health Effects
Primary Routes of Entry : Ingestion, Eyes, Inhalation, Skin Absorption
Aggravated Medical Condition : Asthma, Respiratory disorders, Heart disease

Material Safety Data Sheet
Chlorine
Version 5 Revision Date 04/26/2010 Print Date 04/26/2010
There is no evidence that acute inhalation of chlorine at low to moderate
levels will cause permanent lung damage. At high levels, chlorine is corrosive
to the respiratory tract and may cause lung damage.
Skin : May cause skin irritation and/or dermatitis.
Contact with liquid chlorine may cause burns with prolonged contact causing
destruction of the dermis with impairment of the skin at site of contact to
regenerate.
Eyes : Causes serious eye irritation.
Blurred vision
May cause permanent eye injury.
Ingestion : Ingestion or inhalation of high concentrations may cause injuries to
gastrointestinal tract, liver, kidneys and central nervous system.
Ingestion may cause gastrointestinal irritation, nausea, vomiting and
diarrhoea.
Ingestion is not an applicable route of exposure for gases.
Chronic Exposure : Effects from chronic skin exposure would be similar to those from single
exposure except for effects secondary to tissue destruction.
NTP: No component of this product present at levels greater than or equal to 0.1% is identified as a known
or anticipated carcinogen by NTP.
IARC: No component of this product present at levels greater than or equal to 0.1% is identified as probable,
possible or confirmed human carcinogen by IARC.
OSHA: No component of this product present at levels greater than or equal to 0.1% is identified as a
carcinogen or potential carcinogen by OSHA.
ACGIH: No component of this product present at levels greater than or equal to 0.1% is identified as a
carcinogen or potential carcinogen by ACGIH.

level "B" (Enhanced Level "B" is the addition of a splash hood).
? Responders can reference Chlorine Institute pamphlet #65 on PPE.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions : Restrict access to affected area.
Use personal protective equipment.
Use NIOSH approved respiratory protection.
Keep people away from and upwind of spill/leak.
Vapours can accumulate in low areas
In the case of hazardous fumes, wear self contained breathing apparatus.
Methods for containment / : Do not allow material to contaminate ground water system.
Methods for cleaning up Try to prevent the material from entering drains or water courses.
Prevent further leakage or spillage if safe to do so.
Inform the responsible authorities in case of gas leakage, or of entry into
waterways, soil or drains.
The liquid form is heavier than water. (Will form hazardous reaction products)
Pay attention to the spreading of gases especially at ground level (heavier
than air) and to the direction of the wind.
Retain and dispose of contaminated wash water.
