Purpose
Signal lamp LS-04 falls into group I, category M1 of equipment which is designed for continous work in underground mines and sufrace facilities with a possibility of methane explosions, as well as in surface mine facilities and confined space work where potential explosive atmosphere of mine gas (methane) and/or coal dust can occur temporarily in general work conditions.
Falls into group III, category 2G of equipment which is designed for continuous work in 1 and 2 zones endangered by gases, vapor and mist of group IIB.
It is a warning device adjusted to work with position casings OP-1 which are used to indicate the end of mine trains.
Major advantages:
Spark-proof design ( level "ia ").
Maintenance free, gasproof, battery Ni-MH (so called "hydrogen")
High capacity lighting achieved owing to LED diode system with high intensity luminosity
Battery might be carried on the belt
