EMERGENCY PROCEDURE GUIDE

LIQUID NITROGEN INFORMATION SHEET

EMERGENCY CONTACT:Police or Fire Brigade: 111

NON FLAMMABLE GAS

CLASS: 2.2 UN NUMBER: 1977 HAZCHEM: 2REPHYSICAL DESCRIPTION/PROPERTIES

Appearance: Colourless, odourless Boiling Point: -195.80C Flash Point: Non-flammable Form: Liquid

HAZARDS

Fire Mobile cylinders exposed to heat should be moved away from heat source.Health Liquid and cold vapour can cause severe frostbite with death of tissue, even through normal gloves.

Cold vapour will irritate lungs. Gas acts as an asphyxiate by displacing Oxygen in the atmosphere.Prompt medical attention is mandatory in all cases of over exposure to nitrogen.Ensure own safety before attempting to rescue an unconscious person from an enclosed area.Inhaled: Asphyxiation in high concentrations includes rapid, gasping respiration, rapid fatigue and

vomiting, cyanosis and may lead to loss of consciousness and death. Rescue personnel should beequipped with breathing apparatus and an oxygen resuscitator.Eye:Cryogenic liquid can cause tissue freezing or frostbite if splashed in the eyes.Skin:Cryogenic liquid or items that have directly immersed in liquid nitrogen can cause tissue orfrostbite on dermal contact.Hypothermia: Prolonged exposure to liquid nitrogen can cause an abnormally low body temperature.

EMERGENCY PROCEDURES

IF THIS HAPPENS: DO THIS: FOR ALL EMERGENCIESMove people from immediate area; keep upwind or cross wind, send messenger to notify FireBrigade and Police. Tell them the location, material, quantity, UN number and emergencycontact.

Indicate condition of vehicle and damage observed.Tanker/Vehicle Carry out action under FOR ALL EMERGENCIES

Accident Shut off engine and leave off until vapour hazard is removed. Check for spills or leaks. Do notmove vehicle, as movement could cause spillage. Warn other traffic.

Spill or leak Carry out action under FOR ALL EMERGENCIESDo not enter vapour cloud. Move people from area, do not stay in a Nitrogen enriched area.Avoid breathing vapours and contact with skin and eyes. Wear self-contained breathingapparatus and protective gloves.

Fire Carry out action under FOR ALL EMERGENCIES.

Liquid or Gas will not burn or support combustion. Mobile cylinders exposed to heat should bemoved away from heat source. Do not approach container suspected of being hot. Do notstayin a Nitrogen enriched atmosphere. Withdraw all personnel from area and warn against entry.

FIRST AID

Inhaled Move affected person to fresh air, lay down, rest. If not breathing, apply resuscitation.Preferably using an oxygen resuscitator if available. Keep warm. Transport to a Hospital orDoctor.

Eyes Hold eyes open immediately and wash continuously with water or with a sterile saline solution,for at least 15 minutes. Transport to Hospital or Doctor.

Skin Irrigate affected area with tepid water (300- 35

0) if available for 15-30 minutes. Apply sterile

Cold dry dressing and treat as a thermal burn. If tepid water is unavailable use tap water. Do notBurns apply any form of direct heat. Seek medical attention. Summon ambulance; recommend

admission to hospital for observation.Hypothermia Move person to a warm place. Wrap in blankets. Seek medical attention. Avoid heat.

Summon ambulance; recommend admission to hospital for observation.

SAFE HANDLING INFORMATION

Storage and transport:

Keep cylinders sheltered from rain or water at

all times, this can cause ice to form and sealthe cylinder and explosion may occur.

Protect cylinders from physical damage.

Cylinders should be stored below 45

0

C in asecure, dry, well ventilated firm area, awayfrom heavy traffic areas and emergency exits.

Liquid cylinders (portable) must be transportedwith an open topped vehicle and the load is tobe secure. Wear leather gloves and eye shieldwhen transferring liquid nitrogen.
