storage facilities, and areas where the air contains
chemicals or particles, such as grain, dust, or metal
powders.
Blasting Caps and Areas
Power off your mobile phone or wireless device when in a
blasting area or in areas where signs are posted to power off
"two-way radios" or "electronic devices" to avoid interfering
