Guidance on Safe Use
Administrative data
First-aid measures
Emergency measure - Inhalation: Remove patient to fresh air and seek medical attention.
If not breathing, suitably qualified personnel should give
artificial respiration and, if breathing is difficult, give
oxygen. Continue administration of 100% oxygen for half hour
periods for at least six hours until breathing is easy.
Emergency measure - Eyes: Flush eyes with water for a minimum of 15 minutes. Seek
medical attention immediately.
Emergency measure - Skin: Flush with water for at least 15 minutes while removing
contaminated clothing. Launder clothing before re-use.
Emergency measure - Ingestion: Seek immediate medical attention.
Fire-fighting measures
Recommended extinguishing agent: Dry powder should be used. If unavailable, use sand,
absorbent clay, or carbon dioxide.
Product arising from burning: The substance is pyrophoric and may ignite on contact with
air, evolving noxious fumes eg carbon and arsenic oxides and
acids. Once extinguished, re-ignition may occur on contact
with air.
Product determined by test: N
Protective equipment: Full protective clothing and a self-contained breathing
apparatus must be worn.
Accidental release measures
Emergency measures in case of spillage: In case of accidental spillage evacuate all personnel from
the area. Wear suitable protective clothing (see 2.3.1).
Block off source of spill if possible. Extinguish any fire
with appropriate extinguisher. Keep to a safe distance.
Protect adjacent property. Do not contact with combustible
material. Cover spill with inert absorbent material. Dispose
of in a sealed container as arsenic waste, in accordance
with local regulations. Avoid release to drains.
Handling and storage
Handling: Wear protective clothing, fire resistant gloves, safety
goggles, face shield, safety shoes. Use full protective
clothing when handling. The cylinder must be located in a
fume hood while removing end-caps or plugs. Always handle
under an anaerobic atmosphere. Avoid contact with oxidising
agents, strong acids, chlorocarbons and bromocarbons. Do not
heat in excess of 50 deg C. Inhalation must be strictly
avoided. Do not eat, drink or smoke where this is to be used
and wash hands and face with soap and water after use.
All air, water and other oxidisers must be removed from
piping and equipment for delivery of the substance.
Storage: Always store under an anaerobic atmosphere. Do not expose to
temperatures above 50 deg C. Containers should be stored
upright in a well-ventilated and secure area. Storage should
be away from emergency exits and heavily travelled areas.
Valve caps should remain on containers not connected to
apparatus.
Packaging of the substance and or preparation: All-welded 316 stainless steel containers with nupro valves
and sealed VCR connections manufactured to ASME VIII.

Stability and reactivity
Danger other than fire: Ignition may occur on contact with air. Keep away from
oxidising agents, strong acids and chloro- and bromocarbons.
Chemical reaction with water: Hydrolyses slowly.
Dust explosion determined by test: N
Disposal considerations
Industry - Possibility of recovery/recycling: Recovery for recycling is not possible.
Industry - Possibility of neutralisation: The substance is pyrophoric and rapidly oxidised in air so
that the concentration will decrease as the substance
reacts. The substance decomposes slowly in water.
Industry - Possibility of destruction: controlled discharge: All material should be returned to the supplier for
disposal. It will be neutralised by dilution and
decomposition and then disposed of as arsenic waste to an
appropriate hazardous waste operator.
Industry - Possibility of destruction - incineration: Not recommended.
Industry - Possibility of destruction - water purification: Not recommended.
Public at large - Possibility of recovery/recycling: The substance will not enter the public domain.
