Hydrogen, compressed

Remove victim to uncontaminated area wearing self contained breathing apparatus. Keep victim warm and rested. Call a doctor. Apply artificial respiration if breathing stopped.

Symptoms: In high concentrations may cause asphyxiation. Symptoms may include loss of mobility/consciousness. Victim may not be aware of asphyxiation.

Ingestion is not considered a potential route of exposure.

Water. Dry powder. Foam.

Carbon Dioxide.

None.

In case of fire: Stop leak if safe to do so. Do not extinguish flames at leak because possibility of uncontrolled explosive reignition exists. Continue water spray from protected position until container stays cool. Use extinguishants to contain the fire. Isolate the source of the fire or let it burn out.

Evacuate area. Provide adequate ventilation. Consider the risk of potentially explosive atmospheres. In case of leakage, eliminate all ignition sources. Monitor the concentration of the released product. Prevent from entering sewers, basements and workpits, or any place where its accumulation can be dangerous. Wear self-contained breathing apparatus when entering area unless atmosphere is proved to be safe.

Prevent further leakage or spillage if safe to do so.

Only experienced and properly instructed persons should handle gases under pressure. Use only properly specified equipment which is suitable for this product, its supply pressure and temperature. Purge system with dry inert gas before gas is introduced and when system is placed out of service. Purge air from system before introducing gas. Containers, which contain or have contained flammable or explosive substances, must not be inerted with liquid carbon dioxide. Assess the risk of a potentially explosive atmosphere and the need for suitable equipment i.e. explosion-proof. Take precautionary measures against static discharges. Keep away from ignition sources (including static discharges). Use non-sparking tools. Protect containers from physical damage; do not drag, roll, slide or drop. Do not remove or deface labels. When moving containers, use appropriate equipment. Secure cylinders in an upright position at all times, close all valves when not in use. Suck back of water into the container must be prevented. Do not allow backfeed into the container. Avoid suckback of water, acid and alkalis. Never use direct flame or electrical heating devices to raise the pressure of a container. Leave valve protection caps in place until the container has been secured. Close container valve after each use and when empty. Never attempt to transfer gases from one container to another.

Keep container below 50°C in a well ventilated place. Secure cylinders in an upright position at all times, close all valves when not in use.

The substance must be handled in accordance with good industrial hygiene and safety procedures. When using do not eat, drink or smoke.

Keep away from ignition sources (including static discharges). Use non-sparking tools.

Consider a work permit system e.g. for maintenance activities. Ensure adequate air ventilation. Provide adequate general and local exhaust ventilation. Keep concentrations well below lower explosion limits. Gas detectors should be used when quantities of flammable gases or vapours may be released. Provide adequate ventilation, including appropriate local extraction, to ensure that the defined occupational exposure limit is not exceeded. Systems under pressure should be regularly checked for leakages. Product to be handled in a closed system. Only use permanent leak tight installations (e.g. welded pipes). Take precautionary measures against static discharges.

Guideline: EN 388 Protective gloves against mechanical risks. Additional Information: Wear working gloves while handling containers

Wear eye protection to EN 166 when using gases. Guideline: EN 166 Personal Eye Protection.

When allowed by a risk assessment Respiratory Protective Equipment (RPE) may be used The selection of the Respiratory Protective Device (RPD) must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected RPD. Self-contained breathing apparatus (SCBA) or positive pressure airline with mask are to be used in oxygen-deficient atmospheres Guideline: EN 137 Respiratory protective devices - Self-contained open-circuit compressed air breathing apparatus with full face mask - Requirements, testing, marking.

Wear fire resistant or flame retardant clothing. Guideline: ISO/TR 2801:2007 Clothing for protection against heat and flame -- General recommendations for selection, care and use of protective clothing. Other: Wear safety shoes while handling containers Guideline: ISO 20345 Personal protective equipment - Safety footwear.

Refer to local regulations for restriction of emissions to the atmosphere. See section 13 for specific methods for waste gas treatment. For waste disposal, see section 13 of the SDS.

Stable under normal conditions.

No reactivity hazard other than the effects described in sub-section below.

Can form a potentially explosive atmosphere in air. May react violently with oxidants.

Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.

oxidants

Under normal conditions of storage and use, hazardous decomposition products should not be produced.
