A Haz-Mat Emergency Response Supervisor is the supervisory level of work in the containment, mitigation and clean-up of hazardous materials releases and petroleum spills generally involving other local, State and federal environmental and public safety agencies.  Employees in this classification supervise lower-level Haz-Mat Emergency Response Officers, and direct and advise staff from various other government agencies and private industry contractors at spill sites.

Employees in this classification receive general supervision from a higher-level administrator.  Employees are required to work evenings and weekends and are subject to call-in during non-working hours in response to environmental emergencies.  The work is performed primarily outdoors under varying weather conditions and requires frequent travel throughout the State.  Employees respond to hazardous materials accidents that present a substantial and imminent threat to human health and the environment.  The work may require walking considerable distances over uneven and contaminated terrain while wearing heavy protective gear and carrying heavy equipment and materials weighing 20-100 pounds.  The work requires climbing ladders and entering confined or enclosed spaces such as large tanks, trucks, storm drains and containers as well as facilities such as chemical plants, treatment plants and steel mills.
