Hydrogen is non-toxic at normal temperature and pressure. By diluting the oxygen concentration in
air below the level necessary to support life, it can act as an asphyxiant. Effects of oxygen deficiency
are: 12-16%: breathing and pulse rate increased, muscular coordination slightly disturbed; 10-14%:
emotional upset, abnormal fatigue, disturbed respiration; 6-10%: nausea and vomiting, collapse or
loss of consciousness; below 6%: convulsive movements, possible respiratory collapse and death.
Chronic
Long term exposure to hydrogen has no known health effects. Prolonged exposure to an oxygen deficient
atmosphere (below 18% oxygen in air) may affect the heart and nervous system.
First Aid
Inhaled:
Call doctor. If victim is conscious: Move to uncontaminated area to breathe fresh air. Keep warm and quiet. If
victim is unconscious: Move to uncontaminated area and give assisted respiration. When normal breathing is
restored, treatment as above. Continued treatment should be symptomatic and supportive.
Skin Contact:
Remove contaminated clothing and shoes immediately.
Eye Contact:
If eyes become affected gently flood with tap water for at least 15 minutes, call doctor
Advice to Doctor
Advise doctor that victim has been exposed to an oxygen deficient atmosphere and exposed to acetylene which
is a known anaesthetic.
FIRE FIGHTING MEASURES
Flammability:
Highly flammable. Spontaneously flammable in air. Avoid all ignition sources.
Fire/Explosion Hazard:
Hydrogen is highly flammable and burns with almost invisible flame. Container may rupture when heated. Move
cylinders from fire if safe to do so. Cool cylinders with water from a protected location. If unable to keep
cylinders cool, Evacuate Area.
Extinguishing Media:
Water fog or fine water spray.
Hazchem Code:
2SE
Recommended Protective Clothing:
Breathing apparatus need only be worn if the substance is involved in a fire or in confined space.
ACCIDENTAL RELEASE MEASURES
Personal Protection:
Personnel engaged in the movement of cylinders shall be provided with safety footwear and leather or PVC
gloves. Full cover overalls and safety glasses recommended. In areas where equipment failure may cause an
immediate high concentration of hydrogen, approved self-contained full face respiratory equipment should be
readily available.
Spills and Disposal:
Ventilate area. Stop leak if it can be done without risk. Allow gas to dissipate to atmosphere. Evacuate Area.

General:
Only experienced and properly instructed personnel should handle compressed gases. Cylinder contents and
identification labels provided by the supplier must not be removed or defaced. Colour coding should not be the
only criterion used for content identification.
HANDLING AND STORAGE
Handling
Flammability:
Highly flammable. Spontaneously flammable in air. Avoid all ignition sources.
General:
Only experienced and properly instructed personnel should handle compressed gases. Cylinder contents and
identification labels provided by the supplier must not be removed or defaced. Colour coding should not be the
only criterion used for content identification.
Approved Handlers:
Approved handlers are required if more than 100 m3 is stored on site.
Storage
Separation:
Storage of compressed gas cylinders shall be in compliance with New Zealand regulations. Cylinders shall be
stored in a cool, dry, well ventilated area out of direct sunlight and away from heat and ignition sources. No part
of cylinders shall be exposed to temperatures above 50°C. Cylinders shall be stored upright on a level, fireproof
floor, secure in position and protected from damage. Full cylinders shall be stored separately from empties.
Segregate from oxidant gases and other oxidants in store. Avoid any contact with oil or grease particularly to
the cylinder valve. Ensure equipment is adequately earthed. Suck back of water into the container must be
prevented. Purge air from system before introducing gas. Do not allow backfeed into the container. Use only
properly specified equipment which is suitable for this product, its supply pressure and temperature. Keep away
from ignition sources (including static discharges). Cylinders should be moved by hand-truck or cart designed for
that purpose.
Spills and Disposal:
Ventilate area. Stop leak if it can be done without risk. Allow gas to dissipate to atmosphere. Evacuate Area.
EXPOSURE CONTROLS / PERSONAL PROTECTION
Exposure Standards:
Simple asphyxiant.
Engineering Controls:
Provide adequate local exhaust and dilution (general) ventilation and supply sufficient replacement air to
maintain oxygen concentration above 18%.
Personal Protection:
Personnel engaged in the movement of cylinders shall be provided with safety footwear and leather or PVC
gloves. Full cover overalls and safety glasses recommended. In areas where equipment failure may cause an
immediate high concentration of hydrogen, approved self-contained full face respiratory equipment should be
readily available.
