Luftflaskor i varma miljöer – En undersökning om uppvärmning av kompositflaskor till
With this work we have investigated how the air in the air cylinders of portable breathing apparatuses is heated during work in hot environments equal to those of interior fire extinguishing. The laws, regulations and standards concerning breathing apparatuses have been reviewed. We describe the theoretical relationships between heating and cooling as a result of air outtake and compare these to e
