Not suitable for use in the presence of a flammable anaesthetic mixture. (The incubator is not
intended to be used in a location where flammable anaesthetics may be present. This would
create a serious risk of fire or explosion).
Before oxygen administration, disconnect any nebuliser and tube from the solution holder. (This
is to prevent oxygen flowing into the nebuliser pump and creating a fire hazard).
If fitted, disconnect the water pump control lead and water delivery tube. (The pump is not
intended for use during oxygen therapy and may create a fire hazard).
Do not cover the intensive care unit. (Blocking of ventilation slots/holes may lead to oxygen
enrichment of air in unintended areas leading to an increased risk of fire. It may also lead to
increased concentration of CO
2
in the animal cabinet. Covering the unit may lead to fire hazard
due to reduced dissipation of heat).
Do not obstruct ventilation holes. (Blocking of ventilation slots/holes may lead to oxygen
enrichment of air in unintended areas leading to an increased risk of fire. It may also lead to
increased concentration of CO
2
in the animal cabinet).
Do not exceed 1 lpm (litre per minute) oxygen flow rate. (The maximum safe long-term
concentration of oxygen for canines and felines is achieved at this flow rate and increased flow
may lead to permanent injury or death. Greater flow rates also increase the risk of oxygen
leaking in the event of a fault and could create a fire risk).
The incubator contains no flow restriction or pressure regulator device. The oxygen supply must
be reliably restricted to 400kPa (50psi). Always use a medical grade oxygen pressure regulator
and flow meter that has been serviced in accordance with the manufacturer’s instructions.
Failure of an external device may create a fire or pressure hazard or prevent effective treatment.
It is assumed the operator will be trained in the safe and correct use of such devices.
After oxygen administration, animals and any associated cloth materials must be allowed
sufficient time in the chamber in normal air to allow trapped oxygen to disperse. (Fabric and
similar materials that trap oxygen enriched air may burn vigorously if ignited by a spark or other
source of ignition). Use only pure cotton materials to reduce the risk of static electricity sparks.
Perform the following tests and safety checks before EVERY use for oxygen administration and fill in the
Start-Up Check Sheet.
11.1 Check the cabinet, door and hinges/lock for cracks, damage or loose parts that may allow oxygen
gas to escape and create a fire hazard. Check for gaps between the upper and lower halves of the
white cabinet.
11.2 If fitted, disconnect the flexible tube from the nebuliser solution holder to prevent any flow of
oxygen to a nebuliser pump. This could create a fire hazard.
11.3 Remove the water pan and evaporating block. Disconnect the Brinsea Advance Humidity Pump
tube and electrical cable if fitted. Please note that it is not practical to use the pump during oxygen
administration due to capacity restraints. A hydrated oxygen supply is commonly used and helps
humidify the animal chamber.
11.4 Fit the oxygen hose barb to the inlet hole using the locknut supplied. Check for tightness if already
in place, there must be no gap or oxygen gas could leak and create a fire hazard. The hose barb is
suitable for hoses with a 6mm (1/4 inch) bore size. Always use a hose clamp device and ensure it
is tightly fitted so that the hose cannot possibly fall off.
