Oxygen mask for emergency escape and self-help in fire

Self-generating oxygen mask is used in various situations of hypoxia caused by disasters, and it is an escape tool and personal respiratory protection tool for short-term entry into harmful gas leakage space to troubleshoot. The exterior of the mask is made of imported aluminum foil flame retardant composite material, which has the functions of flame retardant and heat radiation prevention. Its unique oxygen candle starting device can ensure that the oxygen bag is filled with oxygen within 1 minute, thus ensuring the wearer to escape from the disaster site quickly and safely.
