a site and identify the material in it if possible, Transmit information
to an appropriate authority and call for appropriate assistance,
Identify actions to protect themselves and others from hazards,
Establish scene control by isolating the hazardous area and denying
entry.
◉ (DOT) Answer: also regulates the transfer and transportation of
