Safety at JCOR Mechanical

JCOR employees participate in regular random drug and alcohol testing programs. All JCOR employees are required to complete safety training in many areas and all are certified in 10-hour OSHA. Our Safety Officer is certified in 30-hour OSHA as well as 10-hour and has taken numerous other safety classes, including adult CPR and work place first aid. All of our employees take refresher courses as necessary. We hold regular jobsite safety meetings to remind employees of the importance of safe practices on and off of the jobsite. Because of this, JCOR's Experience Modification Factor has been excellent for a number of years. We always have a copy of our site specific safety and emergency plan available at each jobsite and our superintendent and/or foreman are very familiar with what's in it and how to use it.
