4. FIRST AID MEASURES

OBTAIN IMMEDIATE MEDICAL ATTENTION

Inhalation : Remove patient from exposure, Keep warm and rest. Administer oxygen if
necessary. Apply artificial respiration if breathing has ceased or show signs of
failing. During resuscitation, care must be taken to avoid contamination by
substance from the patient. Obtain medical attention.

Skin Contact : If contact with liquid chlorine, remove contaminated clothing. After contact with skin,
wash immediately with plenty of water for at least 15 minutes. Care must be taken to
prevent the spread of material from contaminated clothing. Do not attempt chemical
neutralization or apply any salves or ointments to damaged skin .Obtain medical
attention.

Eye Contact : SPEED IS ESSENTIAL. Immediately irrigate with eyewash solution or clean water,
holding the eyelids apart, for at least 15 minutes. Obtain medical attention.

Ingestion : Do not induce vomiting. Obtain medical attention.

4.1 MOST IMPORTANT SYMPTOMS AND EFFECTS, BOTH ACUTE AND DELAYED.
Contact with this material will cause burns to the skin, eyes and mucous membranes.
Unconsciousness. Cough, shortness of breath, headache, nausea, vomiting. May cause lung damage

4.2 INDICATION OF IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED

Continue oxygen if necessary. Following exposure the patient should be kept under medical review for at least 48
hours as delayed pulmonary oedema may develop. Positive end expiratory pressure pulmonary ventilation plus
steroid therapy should be considered in severe cases. Symptomatic treatment and supportive therapy as indicated.

Revision 7 3/9 01/01/2020

5. FIRE FIGHTING MEASURES

Suitable Extinguishing Media:

Use suitable extinguishing media for the surrounding fire. Keep fire exposed containers cool by spraying with
water. Use water with caution, chlorine in water can be very corrosive. DO NOT spray on to leaking containers.

Specific hazards arising from the substance or mixture:

Non-combustible. Oxidising agent ; may assist combustion. Mixtures of chlorine and hydrogen are explosive
over a wide range of concentrations.

Special Protective equipment and precautions for fire fighters

A self contained breathing apparatus and suitable protective clothing should be worn in fire conditions

Special protective equipment and precautions for firefighters

Special Protective Equipment for Firefighters: Firefighters MUST use self contained breathing equipment, eye
protection and full protective clothing when fighting fires in which chlorine is involved. Use water spray to keep
fire-exposed containers cool, but avoid area where chlorine is leaking.

Fire-fighting equipment/instructions
In case of fire and/or explosion do not breathe fumes. Remove pressurized gas cylinders from the immediate
vicinity. Cylinders can burst violently when heated, due to excess pressure build-up. Cool containers / tanks with
water spray. Evacuate area and fight fire remotely due to the risk of explosion.

______________________________________________________________________________________

6. ACCIDENTAL RELEASE MEASURE

Personal precautions, protective equipment and emergency procedures

Keep people away from and upwind of leak. Keep out of low areas. Closed spaces must be ventilate before
entering. Wear appropriate protective equipment and clothing during clean-up.

Methods and materials for containment and cleaning up

Ensure full personal protection (including respiratory protection) during removal of spillages. Provided it is safe
to do so, isolate the source of the leak. If possible turn leaking containers so that gas escapes rather than liquid.
Neutralised the leak material with limestones and soda ash.

Environmental precautions
Contain spillages with sand or earth, cover with polythene sheeting. Do not allow to enter drains, sewer or
watercourses. Spillages or uncontrolled discharge into watercourses must be alerted to the appropriate regulatory
body.

Revision 7 4/9 01/01/2020

7. HANDLING AND STORAGE

7.1 PRECAUTIONS FOR SAFE HANDLING

Precautions for safe handling

Do not breath gas. Do not use grease and oils. Avoid contact with skin or eyes. Wherever possible should be
handled in high containment systems. Provide adequate ventilation, including appropriate local extraction, to
ensure that the defined occupational exposure limit is not exceeded. Wear appropriate PPE Equipment. Avoid
release to the environment.

Hygiene measures :
Do not eat, drink or smoke when using this product. Wash hands and other exposed areas with mild soap and
water before eating, drinking or smoking and when leaving work. Wash contaminated clothing thoroughly

7.2 CONDITIONS FOR SAFE STORAGE, INCLUDING ANY INCOMPATIBILITIES

Keep container in a well ventilated place. Keep container tightly closed and dry. Keep away from heat and direct
sunlight. Cylinders should be securely kept upright at all times. Drums should be stored horizontally. Check
regularly for leaks.

___________________________________________________________________________________________

8. EXPOSURE CONTROL AND PERSONAL PROTECTION

Atmospheric levels should be controlled in compliance with the occupational exposure limit. For
operations where there is a risk of exposure to chlorine, full protective clothing and suitable respiratory
equipment must be worn.

Wear goggles/face shield.

Revision 7 5/9 01/01/2020

 Skin/Protective Clothing
Wear suitable protective clothing and gloves. Neoprene and butyl rubber are better than PVC.

Respiratory protection
For high (unknown) concentrations suitable respiratory equipment with positive air supply must be
worn. Canister type respirators may be suitable for low concentrations up to 50ppm and short exposure
times. Wear cartridge/canister respirator is used check with protective equipment manufacture’s data.

Thermal Hazards
Wear appropriate thermal protective clothing, when necessary

10. STABILITY AND REACTIVITY

Stability : Stable

Conditions to avoid : The presence of moisture in gaseous and liquid

chlorine increases corrosive attack on most
common metals.

Hazardous Reactions : Oxidising agent ; may assist combustion. Can

react violently if in contact with many organic
materials such as mineral oils and greases
(including silicones) and finely divided metals.
Dry chlorine reacts violently with titanium. Form
explosive compounds with alcohols, glycols,
ammonia and its compound. Form explosive
mixtures with hydrogen over wide range of
concentrations. Can cause an iron/chlorine fire
with steel at a temperatures over 100 deg C.

Hazardous Decomposition Product (s) : Hydrogen chloride in the presence of water.

11. TOXICOLOGICAL INFORMATION

Inhalation : Toxic by inhalation. Irritating to respiratory system. Atmospheric

concentrations in excess of the occupational exposure limit may lead
to immediate severe irritation of the upper respiratory airways,
intense coughing, choking and bronchospasm (15-20ppm); shortness
of breath, chest pain, possible nausea and vomiting (30ppm). There
is some evidence that such exposures may cause bronchial hyper
reactivity in susceptible individuals. Chemical tracheo - bronchitis,
pulmonary oedema may appear up to 48 hours after exposure (above
40ppm)

Skin Contact : Irritating to skin. Gas can cause irritation and may cause blistering
in high concentrations particularly if moist. Liquid causes freeze
burns.

Eye Contact : Irritating to eyes. Gas causes irritation (severity depending on

concentration and duration of exposure above 5ppm).The liquid
causes severe burns.

Ingestion : Will cause corrosion of and damage to the gastrointestinal

tract.

Long Term Exposure : Repeated exposure by inhalation to

concentrations of chlorine in excess of the occupational exposure
standard may result in adverse effect on the respiratory tract.

Acute toxicity : Inhalation LC50 (rat): 293 ppm/1hr.

Irritation Threshold: approximately 0.5 ppm
Unconsciousness and death may occur following exposure to
concentrations above 50ppm, (dependent upon duration of
exposure).
