Self-contained breathing apparatus (SCBA) and pressure-demand supplied air respirators (PD-SAR) with emergency self-contained breathing apparatus (eSCBA) are used for many types of operations or for emergency situations. Because air is supplied to the wearer, and when the respirator assembly includes an eSCBA, these may be used when atmospheric contaminants are unknown, or concentrations are potentially unstable.
3M™ Scott™ Fire & Safety produces a wide variety of self-contained breathing apparatus (SCBA) and other associated firefighting, respiratory protection and communication accessories.
Confined space work requires careful consideration of both known and unknown hazards. If an atmospheric hazard is anticipated, workers should utilize supplied air respirators with an escape cylinder, such as the 3M™ Scott™ Flite Airline apparatus or an SCBA for short duration work. If atmospheric hazards are not expected and workers are breathing ambient air, worker should have an escape only respirator available, such as the 3M™ Scott™ ELSA EEBD Respirator, for added safety.
A dedicated SCBA for escaping a hazardous environment may not be used regularly. While training employees on the use of the escape respirators is critical, infrequent use can be anticipated. Consider SCBA systems that are easy to use, have the appropriate cylinder duration for escape, and are streamlined to include only the features you need. For escape only, also consider the use of emergency escape devices such as 3M Scott ELSA EEBD Respirators.
In some chemical manufacturing processes, routine applications such as taking air samples or checking gauges may involve brief exposure to contaminants. A comfortable and reliable SCBA offers worker mobility for this task and is often the protection of choice.
There are several hazardous jobs that require getting dirty. As an example, cleaning or slopping out storage tanks requires a respiratory protection solution that is easier to clean.
Having multiple models of SCBA or airline systems for different applications can present a challenge relating to training, maintenance and product use. Consider one SCBA with versatility for use in multiple applications such as the 3M Scott Propak-fx SCBA, or one supplied air respirator such as the 3M Scott Flite-COV, for use throughout the plant.
Choosing the right respirator for your work environment is highly dependent upon your application, the duration of use, and the hazards you may encounter. 3M™ Scott ™ Air-Supplied Respirators have top-down convertibility.
These systems can be used to work in, or escape from, hazards including those that are immediately dangerous to life or health (IDLH). SCBA offer the greatest user mobility and can be used for work duration up to 75 minutes.
Supplied air respirators can be either constant flow or pressure demand. 3M Scott systems are pressure demand and include Flite Airline apparatus with an escape cylinder and the RAS Airline equipment without an escape cylinder. Respirators that include a cylinder that include a cylinder can be used in environments that are immediately dangerous to life or health (IDLH). SAR users can work up to 300 feet away from the air source, and for extended periods of time.
When workers are in a space that could become hazardous, regulations often require a supply of escape respirators - easy to use, self contained units with enough air to allow workers to escape to safety.
