A Haz-Mat Emergency Response Officer I is the intermediate 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 respond to emergency incidents to mitigate and contain hazardous materials releases and petroleum spills and direct clean-up activities to ensure public safety and eliminate or minimize environmental damage.  Employees in this classification do not supervise other Haz-Mat Emergency Response Officers.

Employees in this classification receive moderate supervision from a Haz-Mat Emergency Response Supervisor.  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.

Positions in this classification are evaluated by using the classification job evaluation methodology.  The use of this method involves comparing the assigned duties and responsibilities of a position to the job criteria found in the Nature of Work and Examples of Work sections of the class specification.

The Haz-Mat Emergency Response Officer Trainee, Haz-Mat Emergency Officer I and Haz-Mat Emergency Officer II are differentiated on the basis of the degree of supervisory control exercised by the supervisor over these employees. The Haz-Mat Emergency Response Officer Trainee performs duties under close supervision.  The Haz-Mat Emergency Response Officer I performs duties under close supervision at times and under general supervision at other times depending on the complexity of the specific duty being performed.  The Haz-Mat Emergency Response Officer II performs the full range of duties and responsibilities under general supervision.
