4. FIRST AID MEASURES

Description of first aid measures

General advice Immediate medical attention is required. Show this safety data sheet to the doctor inattendance.

Inhalation Remove to fresh air and keep comfortable for breathing. If breathing is difficult, giveoxygen. If breathing has stopped, give artificial respiration. Get medical attentionimmediately.

Skin contact Immediately flush skin with plenty of water for at least 30 minutes. Remove contaminatedclothing and shoes. Immediate medical attention is required.

Eye contact Immediately flush eyes with running water for at least 30 minutes. Remove contact lenses,if present and easy to do. Continue rinsing. Keep eye wide open while rinsing. Do not rubaffected area. Immediate medical attention is required.

Ingestion Not an expected route of exposure.

Self-protection of the first aider RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHINGAPPARATUS. Use personal protective equipment. Avoid contact with skin, eyes andclothing.

Most important symptoms and effects, both acute and delayed

Symptoms Inhalation of corrosive fumes/gases may cause coughing, choking, headache, dizziness,and weakness for several hours. Pulmonary edema may occur with tightness in the chest,shortness of breath, bluish skin, decreased blood pressure, and increased heart rate.Chemical pneumonitis and pulmonary edema result from exposure to the lower respiratorytract and deep lung. Residual pulmonary malfunction might occur. May cause burns ofeyes, skin and mucous membranes.

Indication of any immediate medical attention and special treatment needed

Note to physicians Treat symptomatically.

5. FIRE-FIGHTING MEASURES

Suitable extinguishing mediaUse extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Specific extinguishing methodsContinue to cool fire exposed cylinders until flames are extinguished. Damaged cylinders should be handled only by specialists.

Specific hazards arising from the chemicalNon-flammable gas. The product causes burns of eyes, skin and mucous membranes. Highly soluble in water-will react to yielddense, acrid HCL fumes. Thermal decomposition can lead to release of irritating and toxic gases and vapors. Cylinders mayrupture under extreme heat.

Protective equipment and precautions for firefightersAs in any fire, wear self-contained breathing apparatus pressure-demand, NIOSH (approved or equivalent) and full protective gear.Corrosive hazard. Wear chemically protective gloves/clothing and eye/face protection.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment and emergency procedures

Personal precautions Evacuate personnel to safe areas. Ensure adequate ventilation, especially in confinedareas. Keep people away from and upwind of spill/leak. Monitor concentration of releasedproduct. Use personal protection recommended in Section 8. Wear self-contained breathingapparatus when entering area unless atmosphere is proved to be safe.

Other Information Gas/vapor is heavier than air. Prevent from entering sewers, basements and workpits, orany place where accumulation may be dangerous.

Environmental precautions

Environmental precautions Prevent spreading of vapors through sewers, ventilation systems and confined areas. Donot allow into any sewer, on the ground or into any body of water. Prevent product fromentering drains. See Section 12 for additional ecological information.

Methods and material for containment and cleaning up

Methods for containment Stop the flow of gas or remove cylinder to outdoor location if this can be done without risk.If leak is in container or container valve, contact the appropriate emergency telephonenumber in Section 1 or call your closest Messer location.

Methods for cleaning up Return cylinder to Messer or an authorized distributor.

7. HANDLING AND STORAGE

Precautions for safe handling

Advice on safe handling Many metals corrode rapidly with wet hydrogen chloride.

Protect cylinders from physical damage; do not drag, roll, slide or drop. When movingcylinders, even for short distance, use a cart designed to transport cylinders. Never attemptto lift a cylinder by its valve protection cap. Never insert an object (e.g. wrench, screwdriver,pry bar,etc.) into valve cap openings. Doing so may damage valve, causing leak to occur.Use an adjustable strap wrench to remove over-tight or rusted caps. Use only withadequate ventilation. Use a backflow preventive device in piping. Use only with equipmentrated for cylinder pressure. Close valve after each use and when empty. If user experiencesany difficulty operating cylinder valve discontinue use and contact supplier. Ensure thecomplete gas system has been checked for leaks before use.

Never put cylinders into trunks of cars or unventilated areas of passenger vehicles. Neverattempt to refill a compressed gas cylinder without the owner's written consent. Never strikean arc on a compressed gas cylinder or make a cylinder a part of an electrical circuit.

Only experienced and properly instructed persons should handle gases under pressure.Always store and handle compressed gas cylinders in accordance with Compressed GasAssociation, pamphlet CGA-P1, Safe Handling of Compressed Gases in Containers. Foradditional storage recommendations, consult the CHLORINE INSTITUTE PAMPHLET 99for Hydrogen Chloride.

Conditions for safe storage, including any incompatibilities

Storage Conditions Store in cool, dry, well-ventilated area of non-combustible construction away from heavilytrafficked areas and emergency exits. Keep at temperatures below 52°C / 125°F. Cylindersshould be stored upright with valve protection cap in place and firmly secured to preventfalling. Use a "first in-first out" inventory system to prevent full cylinders from being storedfor excessive periods of time. Full and empty cylinders should be segregrated. Storedcontainers should be periodically checked for general condition and leakage.

Incompatible materials Incompatible with strong acids and bases. Incompatible with oxidizing agents. Fluorine.Calcium carbide. Cesium carbide. Rubidium carbide. Lithium silicide.

HYDROGEN CHLORIDE 7647-01-0

Ceiling: 2 ppm Ceiling: 5 ppmCeiling: 7 mg/m3

IDLH: 50 ppmCeiling: 5 ppm

Ceiling: 7 mg/m3

ACGIH TLV: American Conference of Governmental Industrial Hygienists - Threshold Limit Value. OSHA PEL: OccupationalSafety and Health Administration - Permissible Exposure Limits. NIOSH IDLH: Immediately Dangerous to Life or Health

Other Information Vacated limits revoked by the Court of Appeals decision in AFL-CIO v. OSHA, 965 F.2d962 (11th Cir., 1992).

Appropriate engineering controls

Engineering Controls Showers. Eyewash stations. Provide general ventilation, local exhaust ventilation, processenclosure or other engineering controls to maintain airborne levels below recommendedexposure limits and to maintain oxygen levels above 19.5%. Exhaust gas should be ventedto a gas treatment system. Consider installation of leak detection systems in areas of useand storage. Systems under pressure should be regularly checked for leakages.

Individual protection measures, such as personal protective equipment

Eye/face protection Tight sealing safety goggles. Face protection shield.

Skin and body protection Appropriate protective and chemical resistant gloves, clothing and splash protection, or fullyencapsulating vapor protective clothing to prevent exposure. For materials of constructionconsult protective clothing manufacturer's specifications. Work gloves and safety shoes arerecommended when handling cylinders.

Respiratory protection If exposure limits are exceeded or irritation is experienced, NIOSH approved respiratoryprotection should be worn. Positive-pressure supplied air respirators may be required forhigh airborne contaminant concentrations. Respiratory protection must be provided inaccordance with current local regulations.

General Hygiene Considerations Handle in accordance with good industrial hygiene and safety practice. Do not get in eyes,on skin, or on clothing. Do not eat, drink or smoke when using this product. Remove andwash contaminated clothing before re-use. Contaminated work clothing should not beallowed out of the workplace. Regular cleaning of equipment, work area and clothing isrecommended.
