Protect ventilation ducts from damage and holes. Keep operation close to the hood to improve capture of vapors and fumes. Be aware of special precautions required when ventilating potentially explosive or corrosive vapors. Prevent recirculation of exhaust air back into the workplace. Evaluate the ventilation system periodically to ensure it is operating as designed.
Problems can occur with ventilation equipment, like any other tool used at work.
Contact your employer if you experience problems with a ventilation system. Most often a routine maintenance program of cleaning out ducts, replacing fan blades and repairing leaks will restore a system to full operation.
