Handling with NH3 Ammonia, anhydrous
By: CBL Safety Pillar
Ref: CANUTEC Emergency Response Guidebook 2008

NH3 Potential Hazards
• Health
– TOXIC; may be fatal if inhaled, or absorb through skin – Vapors are extremely irritated and corrosive – Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite – Fire will produce irritating, corrosive and/or toxic gases – Runoff from control may cause pollution

NH3 Potential Hazards
• Frostbite at different level

NH3 Potential Hazards
• Fire or Explosion
– Some may burn but none ignite readily – Vapors from liquefied gas are initially heavier than air and spread along ground – Some of these materials may react violently with water – Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices – Containers may explode when heated – Ruptured cylinders may rocket

Personnel Safety
• Call CBL Emergency Service
– Immediate precaution measure, isolate spill or leak area for at least 100 meters in all direction

Initial Isolation distance

Initial Isolation Zone

Spill

Personnel Safety
• Call CBL Emergency Service
– Keep unauthorized person away – Stay upwind – Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks…) – Keep out low areas – Ventilate closed spaces before entering

Personnel Safety
• Protective Clothing
– Wear positive pressure self-contained breathing apparatus (SCBA) – Wear chemical protective clothing that is specifically recommended by manufacturer.

Personnel Safety
• Evacuation
– Spill

Emergency Response
• Fire
– Small fire: use dry chemical or CO2 fire extinguisher – Large fire: water spray, fog or regular foam

Emergency Response
• Spill or leak
Fully encapsulating, vapor protective clothing should be worn for spills and leaks without fire Do not touch or walk through spill material Stop the leak if can do it without risk Prevent entry into waterways, sewers, basements, or confined areas Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water run off to contact spill material Isolate area until gas dispersed

Emergency Response
• First Aid
– Move victim to fresh air – Call our Emergency Medical Service (157/158) or Ambulance 119 – Give artificial respiration if victim is not breathing

Emergency Response
• First Aid
– Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of pocket mask equipped with a one-way valve or other proper respiratory medical service

Emergency Response
• First Aid
 Administer oxygen if breathing is difficult  Remove and isolate contaminated clothing and shoes  In case of contact with liquefied gas, thaw frosted parts with lukewarm water

Emergency Response
• First Aid
In case of contact with substance, immediately flush skin or eyes with running water for at least 20 min. Keep victim warm and quiet Keep victim under observation Effects of contact or inhalation may be delayed Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
