Unlike compressed gas cylinders which are potentially explosive, the R15 can be stored safely in all public areas such as airports, office buildings, schools, malls, golf courses... anywhere that people gather. Plus, the R15 can be placed on a shelf or any visible area where everyone can see it for quick access in emergencies. Oxygen cylinders must be stored in fire resistant cabinets and only people who have specific training may activate an oxygen cylinder. The R15 is the only accessible emergency oxygen with no special storage or training required. It is an essential emergency safety device to have on hand. The R15 improves emergency readiness and reduces potential liability. Effective CPR provided by a bystander in the first few minutes of cardiac arrest can increase survival 2 or 3 times. Every second without oxygen can negatively affect survival: improve your emergency preparedness program by adding emergency oxygen with the R15.
