Koehler is an important manufacturer of safety lamps. the aluminium Koehler lamp was approved by the USBM as No. 209 on April 30, 1948. The lamps were designed to provide light and also to test for presence of toxic gases. If flammable gases were present, the light inside the lamp changed colour to a bluer tint. The lamps were not safe, as soon as a part rusted, loosened or cracked the lamps could actually ignite fire. They did not decrease the number of accidents.
