| Abstract |
A comparison of demand-type and rebreathing-type self-contained respiratory protective equipment (weight, length of use) comes out in favour of the rebreathing-type apparatus. By raising the operating pressure to 300 bars, it has been possible to increase the service time of demand-type respirators and at the same time reduce their weight. It has also been possible to reduce the weight of rebreathing-type respirators. Advice is given on the use of this type of apparatus. A mixed-gas rebreathing apparatus (60% oxygen, 40% nitrogen) has been developed for use in pressurised atmospheres. |
