Product Introduction
isolation-type chemical oxygen self-rescuer is produced on the basis of the MT425-1995 standard ( starter oxygen candles of the chemical oxygen self-rescuer meet the requirements of the AQ1057,the potassium superoxide comply with the provisions of MT427-1995).
When the coal mine gas and coal dust content is very high, disasters such as explosions, fires or roadway blockage，case the environment hypoxia, or harmful, toxic gases endanger miners' lives, please worn it timely to evacuate area safely.
When the coal mine gas and coal dust content is very high, disasters such as explosions, fires or roadway blockage，case the environment hypoxia, or harmful, toxic gases endanger miners' lives, please worn it timely to evacuate area safely.
Mainly used for coal mine and other potentially toxic gases and asphyxiation environment.
