Self-contained breathing apparatus (scba) PROMPT DELIVERY

Types and differences between various models of breathing apparatus

Self-contained breathing apparatus are designed and built to support human intervention in all conditions, so they are produced in different versions, each designed for one area of use.

The structure of the device normally consists of a "shoulder strap" (backrest with belts) to be worn like a backpack, on which is installed a pressure reducer, the regulator with breathing mask, a cylinder loaded with high-pressure air (200/300 bar) that provides air reserve (up to 60 minutes), and an audible alarm (Whistle) essential for warning of air exhaustion.

• Self-contained breathing apparatus Type 1, for general use (Industrial emergency team, confined spaces and first aid).
• Self-contained Type 2 / FR breathing apparatus, supplied to firefighters or high-risk emergency teams, this version has passed the flash-over resistance test and is suitable for operations in high-temperature environments.
• Self-Escape Breathing Apparatus, follows the same concept as the classic self-contained breathing apparatus with the difference that it comes with a hood to wear and a bag containing the cylinder. Intended purely for extreme emergency use, we can, for example, find it equipped on a forklift.

European Standard EN 137

Accessories and spare parts for breathing apparatus

All components connected to the rebreather (mask, regulator, cylinder) can be replaced independently, complying with the manufacturer's guidelines, except for the backrest and its pressure reducer and pressure gauge, which must be subjected to the manufacturer's exclusive handling. Listed below are the main accessories for rebreathers:

Full face mask with CL2 or CL3 screen

Hypoallergenic silicone full face mask

Low pressure strap for second operator (emergency)

Dispenser with bayonet connection, allows use of full face mask with multi-purpose filter

Self-contained breathing apparatus maintenance and overhaul, when and how to do it

As self-contained breathing apparatuses are "life-saving" devices, they must be subjected to expiring and regular maintenance as required by regulations. Maintenance should be carried out only by the manufacturer or by a workshop authorized annually by the manufacturer.

The frequency of maintenance is dictated solely by the manufacturer, who makes the expiration dates explicit in the owner's manual.

The air cylinder, on the other hand, follows current regulations, which require that every 12 months the air inside it be replaced (even if not used), and every 10 years the cylinder must be tested at an authorized institution.

How to choose the right self-contained breathing apparatusB

A self-contained breathing apparatus is a self-contained life-saving device that allows the user to deal with emergencies, rescues and fires while protecting themselves. It is also used as an airway protection device during maintenance work inside the work area or during particular stages of production. It is important to choose the right self-contained breathing apparatus for your company to be ready for any event.

For example, we can choose escape breathing apparatus and install it on a forklift that normally handles toxic materials. We will choose type 1 breathing apparatus to provide emergency equipment for our company's firefighting team. Common sense would want to provide for an escape self-contained breathing apparatus available to the emergency team, in addition to the classic Type 1 self-contained breathing apparatus already in place, in a chemical company with a high risk of fire or toxic contamination to be worn by an injured person during an emergency recovery in a noxious area. The choice of an FR type 2 self-contained breathing apparatus when there is a need to operate in environments at other temperatures such as maturing stoves at 80CB0, ensuring the unchanged integrity of the self-contained breathing apparatus in hot atmospheres.
